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.

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.

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