Buy Pink Batts and Install Them Yourself

Roof insulation can be installed before or after plaster. Often the insulation installers will find it easier to install before plaster. The roof insulation segments are simply pushed up into place between the ceiling joists with long sticks. The insulation is precut to ensure a snug fit between the ceiling joists assuming that the joists are spaced at the industry standard; 450mm or 600mm. If the spacing is excessive or uneven it can make it difficult for the installers to insert the roof insulation from underneath and the decision may be made to preload the roof with unopened bags of insulation and install them from above.

Calculating the Amount When You Buy Pink Batts

The number of bags required is easily calculated by dividing the number of square metres in the roof space by the number of square metres of insulation in the bags and then deducting 10 percent to allow for the timber framing itself. R2.5 segments are on the thinner end of the scale and less rigid, making them more difficult to install from underneath, even if the joist spacing is optimal. This may also provide a reason to opt for installing the insulation after plaster, from within the roof cavity.  Installing roof insulation in the cavity of a new home is usually a much more pleasant experience compared to older homes. Unlike old houses, new buildings haven’t had time to accumulate the layers of dirt and dust that an old roof will inevitably accumulate over a number of decades.

While it is fully possible for someone to install the insulation on their own, installers will often choose to work a fellow team member. Working as a team of two has several benefits. Apart from the social element of doing a tough job together with a friend, working as a team of two can use less than half the time one installer would need on their own. Benefits are especially felt when loading bags through the manhole which can be quite tedious and time consuming to do alone.

Installing Insulation from Within the Roof Cavity

Roof cavities are typically quite hot, so installers usually prefer to start early, before the temperature inside the roof cavity becomes too high to work in safely. Installers often bring a couple of extra bags of insulation with them “just in case”. Up in the ceiling space the installers will split one bag open at a time and, using their installer sticks, (this might be as simple as a broom handle with a nail fixed to the end), will get to work deftly fitting the insulation batts between the ceiling joists, starting in the furthest corner. Once the roof insulation installation is complete installers can be expected to clean up any leftover scraps before fitting the final piece of insulation over the manhole cover.

Roof insulation is by far the most cost-effective way towards keeping your electricity bills down and maintaining a pleasant indoor temperature all year round. Buy Pink Batts this winter and get a free delivery anywhere in New Zealand!

Knauf Insulation Ticks All the Boxes

Knauf Earthwool Insulation Ticks All the Boxes

Pricewise Insulation is one of New Zealand’s popular retailers of thermal and acoustic insulation. One of their most popular brands is Knauf Earthwool. Earthwool segments are made from fiberglass, similar to most other brands of bulk insulation. However, this German brand of insulation has gained significant popularity due to several distinct features which helped to set it apart from other recognized brands.

An Industry First – Low Itch Glasswool

Since its invention, fiberglass insulation has been associated with itching and discomfort. While some have been worse than others all were more or less itchy to work with. Knauf developed Earthwool to be the least itchy glasswool insulation on the market. In addition to the total absence of any nasty chemicals, Knauf insulation segments contain longer and softer strands compared to other types of glasswool. Fewer strands means fewer ends, which are the primary cause of discomfort when handling glasswool.

More Segments Per Pack = Savings For All

Insulation segments of all makes come in polybags and the amount of square metre coverage in the bag largely depends on the r-value (and thickness) of the insulation in the bag. Earthwool is packaged using advanced compression packaging technology, meaning one bag of Earthwool may contain over twice as much insulation as other brands of the same r-value. This is a real cost saver for suppliers, builders and installers alike. Earthwool insulation retailers can thus store far more Earthwool insulation than any other brand in the same warehousing situation, reducing the overall cost of storage. Builders and DIY renovators inevitably save on transport costs as a smaller delivery vehicle may suffice. Insulation installers themselves also benefit as there are fewer bags to carry around on building sites and into roof cavities, fewer bags to open and fewer bags to dispose of.

Environmentally Friendly and Safe to Work With

In addition to the above-mentioned features, Earthwool shares all the benefits generally associated with glasswool insulation. Fire safety considerations are a key component of good building design. Earthwool is completely non-combustible, meaning that it won’t burn in the event of a fire. Knauf Insulation contains no added formaldehyde and is non-hydroscopic, meaning it doesn’t adsorb airborne moisture.  It is safe to handle and install and requires no special protective equipment. It is, however, always recommended to use protective glasses and a dust mask, especially if working in very dusty environments, ie. old roof cavities, or when installing insulation above your head.

Savings on Energy Bills Far Exceed Initial Cost

If you decide to install Knauf Insulation yourself in your home, use common sense and follow basic safety procedures and recommendations which are available on the manufacturer’s website. Alternatively, if you’re not the DIY type, you might be better off booking in a professional insulation installer to do the job for you. Earthwool insulation is a quality glasswool product and comes with a 50-year manufacturer’s warranty. Over the course of the life of the home you can expect your initial investment in Knauf insulation to be saved back many times over.

Premium Sound Solutions with Greenstuf Insulation

Premium Sound Solutions with Greenstuf Insulation

Autex has a made a name for itself in the market for dealing with acoustic sound insulation products. Autex manufactures insulation from polyester and specialises in both thermal and acoustic insulation and a range of specialty carpets and decorative peel and stick panels.

The thermal and bulk insulation is branded as Greenstuf. Greenstuf insulation has grown in popularity over the years as the no itch alternative to the traditional glass wool insulation. This is particularly relevant to allergy sufferers but has also proven to be a favourite with retired insulation installers who, for example, might want to insulate their own house and who handled more than enough glass wool in their life.

Out of all the types of bulk insulation polyester is the most pleasant to work with. It is important to note, however, that today’s glass wool insulation is much improved to what was commonly sold on the market several decades ago.

Being such a large product, bulk insulation is quite costly to store and to transport. This is also the case with Autex’s Greenstuf insulation. Greenstuf is therefore commonly manufactured to order, shipped directly out of the nearest factory to the home or building site where it will be installed.

Wide Range of Acoustic Panels

Autex Insulation manufactures an impressive range of acoustic sound panels, designed specifically for use in libraries, commercial businesses and any other place where reduced noise level and a stylish design are important considerations. The peel and stick panels come in a huge variety of classic and modern colours. They can be mixed and matched to fit in with almost any building’s interior design.

Acoustic Insulation for Internal Walls

Autex Insulation’s range wouldn’t be complete without its Greenstuf Sound Solution. These acoustic insulation segments are manufactured for internal wall cavities. They fit snugly between the wall studs and are very effective at reducing the amount of noise which is transferred throughout the house interior and also between the external walls of the house.

Reduce Cold Spots with Underfloor Insulation

The popular underfloor insulation comes in long rolls which can be conveniently stapled to the floor joists immediately below the exposed floor boards. If you’re installing insulation it’s important to avoid unduly compressing the insulation as the performance r value of all bulk insulation will always be most optimal when it is allowed to expand to its full width. Any compression will reduce the effects of insulation.

About Pricewise Insulation New Zealand

Autex Insulation is one of a number of several insulation brands sold by New Zealand retailer Pricewise Insulation. Pricewise sells insulation segments and related products to builders, insulation installers and home renovators in all of New Zealand’s major cities and throughout most regional areas. Their other popular brands include Pink Batts, Knauf Insulation (known for their soft handling and “don’t miss the itch”) and CSR Bradford. Bulk orders are delivered typically within 1-3 business days at a reasonable cost.

Increased Comfort With Better Ceiling Insulation Ratings

Increased Comfort With Better Ceiling Insulation Ratings in New Zealand

If we know how to keep a cup of coffee hot for hours, and we know how to keep our drinks chilled on a hot day, what’s to stop people from using that knowledge on a large scale? By understanding the fundamental properties of insulation and conductivity, there is nothing to stop anyone from applying the same principles when constructing a house or other building. The only difference is that instead of keeping a mere cup of coffee warm or a cool drink chilled, we’re talking about keeping people warm or cool, regardless of the weather conditions outside.

Keeping You Warmer in Winter…

As we know, insulation is a material that has high insulating properties. In other words, it is difficult for heat to pass through. During winter, we generate heat inside our homes to keep warm. If, however, we don’t have wall and roof insulation, the heat is able to pass through quite easily. This is because common building materials are generally poor insulators. Consequently, our heaters have to continually generate heat to keep our houses at a comfortable temperature. By installing insulation in the walls and ceiling, we make it difficult for the heat to escape and our house essentially becomes an enormous version of a thermos.

… and Cooler in Summer

Do the same principles apply during the summer? Yes, they do. Houses with higher home insulation ratings can be likened to a massive variety of an esky which keeps our cool drinks chilled. The heat is now being generated by the sun on the outside of the house and finding it very difficult to penetrate the external walls and ceiling. The effects of a poorly insulated home, on the other hand, can be likened to a can of drink sitting in a backpack that has been left in the sun for hours. Of course insulation can’t prevent all heat from passing through and the unrelenting rays of the sun will eventually penetrate the home, but it takes a lot longer. In fact, even if the house has warmed up a little by late afternoon, measures can often be taken overnight to cool it down again.

Choosing the Right Ceiling Insulation Ratings

One of the factors determining how well ceiling insulation will perform in New Zealand is the thickness of the material. Fortunately home owners and DIY renovators don’t have to worry about deciding how thick is good enough. This information is already available through reliable sources. All insulation products come with an R-value (recognised all over New Zealand) which is a definition of how effective it is. The higher the rating, the better it performs. The Building Code sets out minimum requirements for insulation in new housing, measured in R-values and categorised by climate zones. Many insulation experts recommend that home owners increase their home insulation ratings by going for a slightly higher R-value than specified by the Building Code. The benefits are often very noticeable, with increased comfort and energy savings. As the initial cost is only marginally higher, many home owners report having earned back the extra expense already in the first few years.

Polyester Autex Insulation vs Pink Batts Glasswool vs Polystyrene

Which insulation brand is best? Polyester Autex Insulation vs Pink Batts Glasswool vs Polystyrene

Is Polystyrene Insulation an Effective Thermal Barrier?

Polystyrene is one of the most common plastics used today. Extruded polystyrene (XPS) is made from a polystyrene polymer using an ‘extrusion’ technique and is used as thermal insulation.

Still Air is Practically the Best Insulator That Exists

Any type of bulk insulation works on the same principal, no matter what material is used. The aim is to create as many air pockets as possible inside the material. The more air you can trap inside your material, the more effective your material will be at resisting heat flow. If, in addition to the air pockets you create, the material itself has high insulating properties, then you have managed to manufacture an excellent insulator.

Polystyrene has a High Thermal Resistance

Extruded polystyrene (XPS) contains millions of air pockets trapped within the foam. Because the polystyrene itself is also highly resistant to heat, the result is a great thermal insulator which can give excellent R-ratings. In addition to this, XPS is often lined with aluminium foil on at least one side, causing heat to be reflected and blocked simultaneously. This combination of bulk and reflective insulation is very effective.

Excellent Moisture Resistance

When installing glasswool insulation, such as Pink Batts or Bradford, it’s important to ensure that the area you are working in is completely dry, as moisture that becomes trapped can cause mould issues. Moisture can also cause batts to compact which lowers their effectiveness and essentially their R-value. XPS, on the other hand, is already compacted and very little moisture is able to penetrate, preventing mould from developing and ensuring a consistent and durable R-value.

Popular With Installers Due to Ease of Handling

Polystyrene insulation is near odourless, making it a popular choice with professional installers. Unlike glasswool, where thousands of loose fibres detach themselves during installation and often irritate exposed skin, XPS has a dense structure, making it more comfortable to work with. Standard construction site safety wear is more than adequate when installing XPS, compared to glasswool installers who often take protective measures to avoid inhaling tiny fibres and contact with eyes and skin.

Environmental Considerations

Unfortunately a lot of polystyrene ends up in landfill as there are no known biological agents that can break it down. So while XPS is a very high performing insulating material, one of its major drawbacks is the impact it is having on our environment. This may be why many people still opt for glasswool such as Knauf insulation, Bradford Gold or Pink Batts. Greenstuf insulation, manufactured by Autex, is yet another alternative and is made out of polyester. When installed correctly, Autex thermal insulation has the same performance r-value as its glasswool equivalent. Autex insulation is an attractive option for asthma and allergy sufferers in New Zealand.

Classic Issue: Insulation Bag is Bigger Than Manhole

What do when the house manhole is too small to fit the insulation bag

For some DIY renovators, working with insulation installation is not something they do every day. Quite often these people have done a bit of research and discovered that their home doesn’t have adequate ceiling insulation. They go up through the manhole, carry out some measurements and buy Pink Batts insulation with Pricewise Insulation. The reason they go with Pink Batts insulation is to make use of the free delivery offer in New Zealand. Additionally, they decide to save a few dollars by installing it themselves. They’re not exactly thrilled about the prospect, but best not to think too much about it – it can’t be that bad.

All Ready to Go, Or Not

The insulation arrives and they’ve got everything else they need; gloves, knife and dust mask. They brace themselves to get started and what do they find? The bag of Pink Batts insulation won’t fit through the manhole… They haven’t even started on the job and there are problems already. This was not part of the plan!

Getting Someone to Help You May Solve the Problem More Quickly Than You Think

As with any insulation job, it is always recommended to work together with another person. In the situation described above, it could simply be that you are pushing the Pink Batts bag straight into some angled timbers. If you climb through the manhole first and get someone to push the bag up to you, you may be able to angle the bag away from whatever is blocking its path. This would be by far the easiest option.

You Might Have to Bite the Bullet and Split Open the Bag of Pink Batts Insulation

The rule of thumb in DIY insulation is only to open the insulation bag once it’s in the area that you need to insulate. The reason being that Pink Batts is much easier to carry around in its bagged state and it takes up more space when it expands. If, however, you are working on your own, you may unfortunately have to open the bag and carry the individual batts through individually. This is a tedious and time consuming task, but may be your only option.

Think Safety and Don’t Take Risky Short Cuts

Some installers choose to pull back a few roof tiles and load the bags through the roof. They’ll do anything to avoid splitting open the bags that won’t fit through the manhole. This method is not recommended practice for safety reasons, as the risk of falling from a height is great. Although the prospect of passing each insulation batt through the manhole might seem unbearable, it is by far the safer and recommended option. Having someone there to help you will make the job less daunting. Just make sure that the person passing up the insulation batts is wearing eye protection and a dust mask as many Pink Batts fibres will detach themselves and float down in the process.

An Analysis of How People Keep Warm at Home in Winter

Is your house always cold in winter? Learn how to keep warm with insulation

Recently several articles have been published describing things you can do to keep warm in winter. At first glance is easy to be impressed by these astute people who figure out ways to keep warm that don’t involve turning their heating up excessively. One, they are saving money on their energy bills, and two, they are supporting the environment by reducing energy consumption and carbon emissions.

So Why is the House Still Cold?

But on closer analysis, it seems like these people are missing the point altogether. If they are in fact heating their house, then why is it still cold? If they have actually sealed all the gaps, left the oven door open after cooking, opened the curtains to let in the natural sunlight and closed them after sun down, then why the need for flannel sheets, hot water bottles and woollen socks? It doesn’t make sense.

Old Insulation Can Lose Performance R-Value Over Time

Heat energy doesn’t disappear, it is transferred. And if nothing is there to stop it, it will quite literally travel through the roof. So it sounds like the homes these people are living in are not insulated. Or if they are, the layers of insulation probably aren’t thick enough for their climate zones. Or perhaps they were adequately insulated once upon a time, but the insulation material has moved, settled or become damp over time, losing most of what is referred to as R-value.

Installing Home Insulation – the Real Solution

If your home doesn’t have adequate insulation, then you will constantly be striving to heat up your house, trying to stay warm and the problem will never be fully resolved. However, getting to the core of the matter and installing a sufficient level of insulation correctly (this level will vary depending on the climate in your area) reduces the need for all these special modifications. You will simply turn your thermostat to the desired temperature, confident that the heat you are paying for is staying within the four walls of your house.

Pink Batts Ceiling Insulation Retrofit

Heat is also lost through the walls of the house, but in reality, it is often impractical to install insulation in existing walls. Walls have to be opened up, insulated and then replastered and painted. As such, wall insulation is best installed at the time of construction, so home owners are encouraged to consider carefully how well they will insulate the walls. Ceiling insulation, on the other hand, can in most cases be installed at any time, as access can usually be gained through the manhole. Pink Batts manufactures good quality ceiling insulation in a range of R-values. The higher the R-value, the better the insulation will be at resisting heat transfer. Consequently, the higher the r-value, the more comfortable you will be and the higher your energy savings will be.

Pricewise Insulation offers free delivery all over New Zealand for Pink Batts insulation orders. Minimum quantities apply.

Do Insulation Segments Really Work?

The benefits of insulation batts in New Zealand

Building or renovating? A good strong door, a fresh coat of paint, a well landscaped front yard, new fittings in the bathroom – what you see is often what you get, and if it looks good, then you’ll probably be happy with the result. With insulation segments it’s a bit different. It’s not as visible and home renovators will often “uhm” and “ah” about thermal and acoustic insulation..

Do I really need it? Will it make a difference? How much R-value should I invest in? Will thermal be enough, or should I invest in thermal-and-acoustic (sound) insulation segments also? And perhaps deep down inside there’s this uncomfortable cynic, not convinced that there will be any real benefit. So what are the magic benefits of thermal insulation..? And will you notice any difference?

Grants Still Available for Insulation NZ

Many older homes have no insulation in the walls, and (though hard to believe, considering how long the Warm Up New Zealand – Healthy Homes programme has been running), there are still New Zealand homes without even any ceiling insulation. Landlords have just over a year (until July 2019) to fit their rental properties out with adequate ceiling insulation, in accordance with the Residential Tenancies Act. Grants are still available to home owners or rented homes whose tenants have a community services card or have health problems associated with cold or damp housing. The grants provide 50 percent of the cost of ceiling and underfloor insulation. Over 300,000 existing homes have been insulated since the start of the programme in 2009 and the health benefits of insulation NZ have been substantial. There has been a significant reduction in hospitalizations, including the number of asthma sufferers being admitted to hospital.

Year Round Indoor Comfort with Ceiling Insulation

Quite simply, an insulated ceiling increases indoor comfort – all year round, but especially noticeable during the hottest and coldest months of the year. Insulation segments contain literally millions of invisible air-pockets. These restrict the transfer of heat and cold through one of the most exposed areas of the house – the roof / ceiling area. Installing insulation in ceiling spaces is relatively straightforward. Usually the insulation segments will simply be installed between the ceiling joists, but in the case of habitable attic conversions, then more creative solution needs to be found, since the ceiling cavity itself then needs to be kept at a reasonable temperature. The solution here is to focus on the area immediately underneath the roof itself – typically a combination of foil and bulk insulation will provide the required result.

Year Round Energy Savings

Insulation segments, correctly installed in the walls and ceilings will vastly reduce the amount of energy required to heat the house in winter, and keep it cool in summer. In fact, a proper level of insulation can more than halve your electricity bill! Does installing insulation in the underfloor make a difference too? Yes, not only will you create a more comfortable flooring temperature, you will also save on your energy bills. So, comfort factors aside, thermal insulation is a logical investment which in simple dollars terms, will usually “pay itself off” after only a few years.

Energy Prices on the Rise – Think Higher R Value

How to choose and insulation R-value in Auckland

Will the insulation top-up option be the next trend?

With electricity costs increasing across many areas in New Zealand, the insulation top-up option might soon become the new trend. The r value of thermal ceiling insulation will usually correspond closely to the thickness of the insulation segments. The more you’re paying for your energy, the more likely you will be to save money by topping up the insulation in your ceiling with an extra layer.

Air-conditioning vs Insulation

Here’s how it works: let’s imagine electricity was free, and let’s imagine your house, had no insulation. To compensate, however, your house is fitted out with a top-of-the-range ducted air-conditioning system. On a hot day, the roof space heats up like a furnace, and before long, the ceiling itself is emitting heat which can be felt inside the house. But since it doesn’t cost anything, you just crank up your air-conditioning, and keep the heat at bay… or most of it at least. In this scenario, it would be tempting to just leave the home uninsulated, after all, it’s not costing you anything.. or is it?

The excessive load on the airconditioning system will doubtless lead to higher servicing and repair costs. But you might think that’s not much, compared with the cost of insulating the entire ceiling. But this scenario obviously isn’t from the real world.

Rising power prices in New Zealand

In the real world, (or at least in New Zealand) gas and electricity cost money, and in most areas, the average New Zealand family is more per year for their energy use…all other factors being equal. Which brings us to an interesting point: what if your home is under-insulated­? You might well ask ‘what’s the definition of under-insulated? When is some insulation not enough? One way of looking at it would be as follows: If the cost of increasing the R value would reduce the energy cost by more than this cost, over a reasonable period of time – then your home is probably under-insulated.

How quickly does insulation pay itself back?

For example: let’s say the cost of topping up your insulation (assuming you’ll install it yourself) comes to $600.  You estimate that the increased thermal protection in your roofspace will knock $150 per year off your energy costs. So in 4 years, the investment has practically paid itself off, and thereafter, it delivers savings, year after year. If you consider that to be a good investment, then by this definition, your house is under-insulated, and will benefit from a timely top-up. Happy insulating!

Installing insulation in existing homes

Installing ceiling insulation in old homes is usually done fairly easily. Simply open up the manhole, push the insulation bag through, split open the bag and fit the insulation between the joists. Walls, on the other hand, need to be opened up, insulated and replastered. Think long term and make sure you install adequate insulation during the construction stage, as you won’t be in a hurry to open up the walls again.

Renovating your home? Don’t forget Pink Batts in the walls

Install Pink Batts wall insulation when renovating

Many old homes which were not insulated during the construction stage will by now have had Pink Batts or some other brand of insulation installed in the ceiling. These days, people seem to realise just how much they can save on their energy bills by retaining their heat in winter and reducing heat gains in summer. On the other hand, the focus has not been so much on wall insulation, and with good reason. You won’t save as much on your energy bills and many claim that the initial investment is just too expensive. People learn to live with the whirring washing machines, banging water pipes and other common household noises. They tune out to the constant passing traffic on the main road out the front and it’s really only the visitors that comment on the sounds all around. However, this doesn’t mean that sound insulation is out of the question. You just have to wait for the right time to install it.

Find the right time – install sound insulation during a renovation

To install Pink Batts in walls you have to open up the wall itself. There is no way around this, so it’s no surprise that the walls in many old homes remain uninsulated. People will rarely tear apart a finished, plastered, painted wall simply to install sound insulation. If, however, you are renovating your home, then you should definitely consider insulating any new walls. The bottom line is: if you’re opening up a wall anyway, then consider soundproofing it while you can do it cheaply! You’ll be surprised at how much you will appreciate the reduced noise in your home, and you’ll also save a bit on your energy bills.

Reduce unwanted noise from the outside with Pink Batts

Insulating your external walls reduces the amount of sound that enters your home from the outside. The most common complaints are traffic, aircraft and barking dogs. High-density soundproofing insulation prevents much of the noise from penetrating your home and many sound insulation products also provide a thermally resistant barrier, keeping you warmer in winter and cooler in summer. If you’re opening up any internal walls, consider insulating these too and you will reduce the level of sound that is transmitted from room to room. Media/TV rooms, studios, bedrooms, bathrooms and laundries should be first on the priority list.

Receiving a large amount of bulk insulation?

Bulk insulation is a large and relatively heavy and bags are often wrapped together as bales. These bales can weigh over 70 kilograms and can be quite a challenge to move around. However, by using the right technique, practically anyone who is reasonable fit should be able to move a bale of insulation up a driveway or around a building site without too much trouble. Here’s how to do it: lift the bale up so it’s standing upright (lift it together with another person if necessary). Standing behind the bale, push it forward, using your body weight to assist. As it starts to roll, follow it, continuing to push it as you go. The first push will be the hardest, but after that it will start to pick up momentum.
