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 Bristol

Can you quote for several properties in Bristol?

Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.

Do you cover the whole of Bristol?

Yes. We cover every town and village in Bristol, including every postcode district.

Is it messy?

The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.

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.
