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 Carmarthen
Can you visit Carmarthen 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 loft work in Carmarthen 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.
Do you charge extra to travel to Carmarthen?
Not normally. Our guide prices include normal travel to Carmarthen. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Is it messy?
The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
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.
