Retrofit Insulation

Retrofit Insulation and Rental Homes

Retrofitting insulation into existing homes and rental properties.

A well-insulated home is warmer in winter, cooler in summer, and helps keep your energy costs down. But many older New Zealand houses have little or no adequate insulation, making them hard to heat, uncomfortable to live in, and potentially unhealthy.

Topping up your ceiling insulation is an important first step. Having a thick layer of ceiling insulation creates a resistance to your rising warm air like damming a creek. All insulation comes with a thermal rating or R value, this just means the thermal resistance of the insulation product. Higher the R value generally means better the insulation product. If your house is over twenty years old topping up the insulation could be worth doing.

If there is access and the house has enclosed perimeter , it is recommended to install underfloor insulation and a ground vapour barrier (moisture barrier). Even if it looks dry underfloor installing a vapour barrier is still recommended, as this is a common way for dampness and mold to enter the home. Fungi and mold can lead to a lot of health issues its important to take steps to mitigate. Installing underfloor insulation and moisture barrier will help with the overall comfort to you and your family.
