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 County Down

Do you cover the whole of County Down?

Yes. We cover every town and village in County Down, including Bangor (County Down), Newtownards and Newry.

Are your prices the same across County Down?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

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.

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.
