Having adequate home insulation is one of the most important, effective ways to keep your house healthy. Home insulation will help keep you warm in the winter, reducing the cost of heating your home, and cooler in summer. We have different subsidies available no matter your financial situation.


We can also offer a no obligation Home Energy Check, where one of our trained assessors will go through the house with the owners and talk about small, everyday behavioural changes that can be made to better protect their investment. Typically includes information about best practice for how to ventilate the house properly, reducing mould and condensation and power bills.



Is your current insulation good enough?


If your insulation is 10 years old or more, then it’s unlikely to be performing at its best. Insulation does deteriorate over time. Try the hand-span test for an initial assessment to see if your insulation is performing at its best. If your insulation is below/around hand width then it’s unlikely to be performing well and you should consider replacing or topping it up. All insulation installed before 2008 is recommended to be topped up. In 2008 the Building Code was amended and a thicker layer of insulation is now recommended for the South Island. 


What is insulation?


Insulation is a product that is installed in the roof and underfloor cavities. It works by trapping layers of still air, reducing the heat conductivity, and allowing less warm air to escape your home. If your house is poorly insulated, heating may be less effective and costly to run.


Insulation performance is measured in R values. Over time, insulation compacts, and the effectiveness of it is reduced. If your home was built before 2000, it is likely to need a top up of insulation. All our insulation products have manufacturer’s guarantees for up to 50 years.


Foil Insulation


Under section 26 of the Building Act 2004, a ban has been placed on installing foil insulation into residential buildings with existing electrical installation (retrofitting foil insulation), and the repair of foil insulation that has been damaged in any way. This is due to safety concerns about electrocution, and anyone who breaches this ban may be liable to a fine of up to $200,000.


Our staff are trained in safe foil removal, contact us today for more information.
