What is blown loft insulation?

The machine stays outside or on the landing and the hose runs up to the loft. We hold a board or tray at the eaves so the loose fill cannot block the ventilation path. More about blown loft insulation.

Questions about blown loft insulation in Pwllheli

Not normally. Our guide prices include normal travel to Pwllheli. 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.

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.
