Blown Insulation FAQ

Your Comprehensive FAQ Guide to Blown Insulation Solutions in New Zealand.

Types of insulation


There are many different types of insulation on the market so how do you know which is the right product for your property? Here are the three products we recommend to give you a total insulation solution.

1: Insulate your walls with CosyWall blown Cavity Wall Insulation (CWI):

CosyWall insulation is a light, mineral wool product which is used is to insulate the gap between the interior and exterior walls of your home. It is perfect for most houses in New Zealand and will keep your home cooler in the summer and warmer in the winter. CWI is much easier to install than other products as there is no need to remove the Gib board – it can be done in as little as three hours. Our professional installers will drill small holes in your wall, pump in the insulation so that it completely fills the cavity – unlike some blankets or batts, and then fill and paint the holes to match your existing walls. And we make sure everything is clean and tidy before we leave.

2: Use Loft blown roof insulation in your ceiling

Loft Insulation is water resistant, formaldehyde free, non-combustible, clean, durable and is specially manufactured for installation in roofs, attics and ceiling spaces. It forms a consistent white layer (similar to cotton wool) with no gaps or joins to let heat escape. Because it is blown into your ceiling cavity it can be used in hard to get to areas. It is ideal for insulating flat roofs, and can be installed from outside if necessary.
