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
  • Vapour control layer where the design needs one
  • Insulated plasterboard lining where specified

Questions about rafter insulation in Weymouth

Do you cover all of DT4?

Yes, we cover the DT4 postcode district and the districts around Weymouth.

Do you charge extra to travel to Weymouth?

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

Can a landlord in Weymouth book work for a tenanted house?

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

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.
