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 finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

Questions about loft insulation in Sunbury-on-Thames

Can you visit Sunbury-on-Thames outside working hours?

Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.

Can a landlord in Sunbury-on-Thames book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Do you charge extra to travel to Sunbury-on-Thames?

Not normally. Our guide prices include normal travel to Sunbury-on-Thames. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.

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.

How deep should loft insulation be?

The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
