What is loft insulation?
We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

Questions about loft insulation in Rhondda
What do I need to do before you arrive in Rhondda?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position for your address on the quote.
How long does it take to insulate a loft?
Most lofts in houses take a single day. A large bungalow loft, a loft that needs clearing first or one with awkward access can run into a second day.
