What is rafter insulation?

Because the whole roof slope, the gables and the party walls now have to be insulated, this costs much more than insulating the floor and saves less heat for the money. We check the roof underlay first: a breathable membrane and a felt with no ventilation gap need different build-ups to avoid condensation. More about rafter insulation.

Questions about rafter insulation in Newport, Isle of Wight

Do you take on jobs outside Newport, Isle of Wight?

Yes. We also work in Cowes and Ryde and elsewhere on the Isle of Wight.

Do you charge extra to travel to Newport, Isle of Wight?

Newport, Isle of Wight is reached by ferry, so travel is priced separately and shown on the quote before you book.

Do you cover all of PO30?

Yes, we cover the PO30 postcode district and the districts around Newport, Isle of Wight.

Will it cause condensation?

It can if the build-up is wrong for the roof. Old bitumen felt needs a ventilation gap behind the insulation; a modern breathable membrane may not. We check before we design it.

Is insulating between the rafters better than the loft floor?

Not for saving energy alone. Insulating the floor heats less space and costs far less. Rafter insulation is the right answer when the loft itself needs to be warm.
