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 County Londonderry

Do you cover the whole of County Londonderry?

Yes. We cover every town and village in County Londonderry, including Derry/Londonderry, Coleraine and Dungiven.

Are your prices the same across County Londonderry?

Yes. Our guide prices are the same everywhere we work, and they include normal travel. Your fixed price depends on your loft, not your postcode.

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.

Is it messy?

The hose runs through the house, so we sheet the route and the landing. The fibre stays in the loft.
