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 Haverfordwest

Do you cover all of SA61?

Yes, we cover the SA61 postcode district and the districts around Haverfordwest.

Do you charge extra to travel to Haverfordwest?

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

Can you visit Haverfordwest 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.

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.
