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.

  • Build-up designed for your type of roof underlay
  • Insulated plasterboard lining where specified
  • Rigid insulation between the rafters, joints taped

Questions about rafter insulation in Denbigh

Can a landlord in Denbigh 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 Denbigh?

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

Can you visit Denbigh 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 I use the loft as a bedroom after rafter insulation?

Insulation alone does not make a loft habitable. Fire escape, stairs, floor strength and headroom all come into a conversion, which needs building control.

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.
