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. It earns its place when you need a warm loft. More about rafter insulation.
- Rigid insulation between the rafters, joints taped
- Build-up designed for your type of roof underlay
- Vapour control layer where the design needs one

Questions about rafter insulation in Holyhead
Is loft work in Holyhead different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Do you cover all of LL65?
Yes, we cover the LL65 postcode district and the districts around Holyhead.
Do you take on jobs outside Holyhead?
Yes. We also work in Llangefni and Caernarfon and elsewhere in Gwynedd.
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.
