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
- Tank jacket and pipe lagging in the loft
- Mineral wool to 270 to 300 mm across the whole loft floor

Questions about loft insulation in Cardigan
Can a landlord in Cardigan 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 you visit Cardigan 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.
How do I pay for work in Cardigan?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Does loft insulation need building control approval?
On its own it usually does not, but the work still has to meet the energy standard. The rules differ across England, Wales, Scotland and Northern Ireland, so we confirm the position 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.
