Questions about sheep's wool or natural loft insulation in Johnstone
What do I need to do before you arrive in Johnstone?
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.
Can a landlord in Johnstone 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 Johnstone?

Do moths eat sheep's wool insulation?
Insulation-grade sheep's wool is treated against insects. We use products sold for loft insulation, not raw fleece.
How deep does natural insulation need to be?
It depends on the product's thermal conductivity. Some need slightly more depth than mineral wool to reach the same U-value, which we allow for on the quote.
