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

Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about loft insulation in Tenby
Do you cover all of SA70?
Yes, we cover the SA70 postcode district and the districts around Tenby.
Do you take on jobs outside Tenby?
Yes. We also work in Pembroke Dock and Haverfordwest and elsewhere in Dyfed.
Is loft work in Tenby 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.
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.
