Buy Knauf Earthwool Glasswool Insulation in Auckland, New Zealand

Need insulation? Think Earthwool Glasswool

In New Zealand we are spoiled for options when it comes to insulation brands to pick from. Knauf Earthwool is one of the most modern brands on the market, and is the only major insulation brand which is not manufactured locally. Earthwool is in fact made all over the world, and the New Zealand insulation is sourced directly from England. It looks and feels different to other brands. In fact, many customers who are using this superb product for the first time can’t believe that it’s actually made from glasswool.

Knauf Earthwool uses renewable materials with technological advances

Knauf Insulation has invested heavily in new “ECOSE” technology to bring the itch factor (which for decades has been synonymous with glasswool) – to an unprecedented new low. Like many types of glasswool, Knauf Earthwool is manufactured using recycled glass bottles and has been ranked even more environmentally friendly than real sheep’s wool, according to the U.K’s Green Guide for Specification. The product benefits from a unique binder which includes zero formaldehyde and is founded on renewable bio-based materials instead of old-fashioned petroleum-based chemicals.

Some more info on Earthwool Insulation..

Earthwool insulation is a natural shade of earthy brown, and has no added dyes, bleaches or fake colours. Furthermore it is also less dusty and has a much softer and friendlier feel. As there is no formaldehyde or phenol used in the manufacturing process for Knauf Earthwool it improves the indoor air quality of buildings where these products are installed (compared to conventional glasswool products). One of the secrets behind the absence of itch is the longer strands of insulation. The longer the strands, the fewer strands there are – and less strands of glasswool means fewer of those minute, protruding ends which are the cause of the well known ‘itch’ you may have experienced on the inside of your wrists when working with inferior brands of glasswool insulation.

Compressed for ease of freight and storage

Knauf does a great job off compressing their insulation into the bags they come in. The super-compression factor does come with one warning – you’ll need to take extra care when carrying or transporting the bags, as an accidental slit along the bag will see the earthy coloured segments inside making their break for freedom, and you won’t get them back into the damaged bag without a struggle and lots of strong tape!

Knauf: the company behind the Earthwool brand

German company Knauf manufactures a wide range of glass and rock mineral wool products for a wide variety of applications, and has numerous manufacturing facilities all over the world. Earthwool® insulation segments (in New Zealand they are correctly termed segments rather than insulation batts)  and rolls are extremely versatile and can be used in applications from wall and ceiling insulation to HVAC and certain industrial applications.

It’s not hard for us to recommend Knauf Earthwool – it is after all low-itch, rot-proof, odourless, non-hygroscopic, does not sustain rats, mice or other unwelcome visitors, and won’t encourage the proliferation of fungi or mould. It is chemically neutral, does not contain impurities and comes with a reassuring 50 year warranty.

Happy insulating!
