Now the heating is back on, have you noticed some rooms just never seem to warm up?
In a lot of homes, especially older ones, heat escapes straight through the walls. It’s often the bedrooms and the rooms with outside walls that feel it most. Cold walls can also cause condensation, which is where damp and black mould start to appear.
The good news is it can be fixed from the inside. SprayCork Natural IWI is a natural cork insulation sprayed onto your inside walls. Cork is one of nature’s best insulators, so it helps keep the heat in the room instead of letting it escape through the wall. That means rooms warm up faster, stay warm for longer, and your heating doesn’t have to work so hard.
Because it warms the surface of the wall, there’s less chance for condensation to settle and mould to grow. It’s also breathable, so any moisture in the wall can escape rather than getting trapped. It goes on as a thin, seamless coating, so you won’t lose room space like you would with bulky boards, and it’s KIWA accredited, so you know it’s been properly tested.
