What is blown loft insulation?

The machine stays outside or on the landing and the hose runs up to the loft. Depth markers fixed to the joists or trusses show the installed depth, and the fibre settles into corners that rolls would bridge. More about blown loft insulation.

Questions about blown loft insulation in Johnstone

How soon can you visit a home in Johnstone?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

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.

Can you visit Johnstone 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.

Is blown insulation better than rolls?

It performs about the same for the same depth. It is the faster and neater option in lofts that are awkward to work in, and rolls are better where you want boarding later.

Does blown insulation settle?

Mineral wool loose fill settles a little, which is allowed for in the depth we install. The depth markers let you check it later.
