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 Merseyside

Can you quote for several properties in Merseyside?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

Which council covers my address in Merseyside?

Councils in Merseyside include Knowsley, Liverpool, Sefton, St Helens and others. Your council matters for building control questions and some funding schemes.

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.

Can you insulate around downlights?

Recessed downlights need clearance or a fire-rated cover so they do not overheat. We fit covers where needed and leave a clear zone around fittings that cannot be covered.
