What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The finished depth sits at 270 mm or more, the depth the Energy Saving Trust recommends. More about loft insulation.

Questions about loft insulation in Abergavenny

How do I pay for work in Abergavenny?

Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.

What do I need to do before you arrive in Abergavenny?

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Is loft work in Abergavenny 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.

Will loft insulation make my loft colder?

Yes, and that is expected. The insulation keeps the heat in the rooms below, so the loft above runs closer to the outdoor temperature. That is why pipes and the tank are lagged as part of the job.

How deep should loft insulation be?

The Energy Saving Trust recommends at least 270 mm of mineral wool, and that is the depth we install as standard. Building regulations also set an energy standard for the roof when a loft is insulated. It differs between England, Wales, Scotland and Northern Ireland, so we confirm the target for your address on the quote.
