What is different about insulating an older home's loft?
We work from crawl boards spanning several joists so the ceilings are not loaded, check for loose plaster keys before anything is laid, and usually recommend vapour-open insulation such as sheep's wool or wood fibre. Unfelted slate roofs are naturally well ventilated, but they let in wind-driven rain and snow, which the insulation has to cope with. More about loft insulation for an older house.

Why book with us in Penzance
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Boarding done properly
Storage boards go on loft legs, never straight onto the insulation.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
