Roofing insulation in single storey extension with pitched roof
Posted: Mon Jun 13, 2022 1:41 pm
I have a small single storey extension at the back of my house with a pitched roof, the house is a Victorian terrace and the extension also looks pretty old .
The extension is off the kitchen and has suffered from condensation in past, so I've stripped away all the old plaster, have ventilated and will fit a radiator.
When I've removed the plasterboard ceiling there was no insulation between the ceiling and the roof tiles and the underlay is thick polythene (looks like visqueen) so not breathable.
I want to insulate between the rafters before I fit a new ceiling, but am concerned that the insulation should be breathable, because of the visqueen.
Any advice on suitable insulation products to use?
