How Does CosyWall Insulation work?

The simplest way to describe how CosyWall insulation works is by using the example of a chilly bin effect.

Typically in a home, you have a lid (the roof insulation). and a base (the floor insulation) and all your homes heat passes out through the walls. CosyWall insulation completes your home’s thermal envelope by adding a barrier to the walls of your home, allowing your home to retain its heat.

How can you tell if my homes not properly insulated?

If you’re living in rented accommodation and you’re seeing signs of moisture of mould then you might have an insulation issue.

Typically if there are areas that are missed with insulation, whether it’s the ceiling, underfloor or walls, you’ll see a presence of some form of mould or condensation building up. It becomes quite obvious in bathrooms, behind furniture in your living room and in the back of wardrobes.

If you are seeing these types of problems then you should have a chat to your landlord and point them in the direction of CosyWall. We can work with your landlord to do a home assessment and see what needs sorting out.
