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.

Waste packaging removed
Mineral wool to 270 to 300 mm across the whole loft floor

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.

Will loft insulation make my loft colder?

Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.
