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 Portslade

Do you cover all of BN41?

Yes, we cover the BN41 postcode district and the districts around Portslade.

Can a landlord in Portslade book work for a tenanted house?

Yes. We can arrange access with the tenant directly and send you photos once the work is finished.

Is loft work in Portslade 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.

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.
