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 second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.
- Cables lifted clear of the insulation where possible
- Area under the cold water tank left clear so it cannot freeze
- Tank jacket and pipe lagging in the loft

Questions about loft insulation in Crawley
Is loft work in Crawley 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.
Can a landlord in Crawley book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Will I get a written quote for work in Crawley?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
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.
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.
