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 Llanelli
How do I pay for work in Llanelli?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Do you charge extra to travel to Llanelli?
Not normally. Our guide prices include normal travel to Llanelli. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Llanelli book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
