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 Merthyr Tydfil
Do you charge extra to travel to Merthyr Tydfil?
Not normally. Our guide prices include normal travel to Merthyr Tydfil. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will I get a written quote for work in Merthyr Tydfil?

Can you visit Merthyr Tydfil outside working hours?

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.
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.
