Retrofit Insulation NZ

Retrofit Insulation

As specialist retrofit insulation installers, the jobs we do require us to retrofit insulation into existing houses. 

Due to poor insulation requirements prior to 2008, retrofit insulation jobs are carried out on houses built this century through to older houses that have stood the test of time but are now too cold and draughty for modern lifestyles, or in cases where the initial insulation type used was not high quality. With a growing range of insulation materials and installation methods, we can help you choose the best retrofit insulation product to keep you comfortable all year round, add value to your home and offer great long term benefits. 

It is important to remember that retrofit insulation can sometimes be complex and often involves more complex work than simply placing insulation into walls, ceilings or subfloor cavities. There are complex NZ Standards, NZS4246-2016, that retrofit insulation must meet when it is installed into an existing house.

Houses must be assessed on a case-by-case basis to determine if they are suitable for retrofit insulation and if the proposed methods and materials are appropriate. When considering retrofit insulation for your property we recommend consulting an insulation specialist to discuss the best way to go about this. 

Most of our insulation types are suitable for retrofit insulation projects, and as with any other job, we will assess your requirements and make a recommendation on the best retrofit insulation to suit your particular project.
