Most New Zealand homes require – or at least benefit a lot from – some insulation. One of the benefits of insulation is drastically reducing the amount of heat which enters the home in summer, and the amount of heat which escapes in winter. Insulation helps to maximise the efficiency of indoor heating and cooling, and greatly lightens the load on the air conditioning unit or other heating and cooling systems.
How much does it cost to insulate a roof?
Not as much as you’ll pay in energy bills if you don’t insulate your roof! Ceiling insulation should be the first priority in any home insulation project. The roof space is usually the biggest culprit in transferring heat into the home, and in winter time, without ceiling insulation, much of the indoor heating will escape up and out through the ceiling. Ceiling insulation alone can reduce electricity consumption by up to 40%. For most homes, the cost of buying and installing ceiling insulation will be saved back in reduced power costs, after only a few years. And since home insulation can be expected to last as long as the home itself – the insulation will potentially save the home owners many thousands of dollars on their electricity bills over the life of their home.
Thermal and acoustic benefits of insulation
If you live in a noisy neighbourhood or wish to isolate noise within the home, then thermal acoustic insulation is highly recommended. In addition to providing a high level of thermal protection, acoustic insulation’s added density helps it to block out unwanted noise, such as aircraft noise, lawn mowers or barking dogs.
