YBS BreatherQuilt is a 40mm thin dual-purpose breathable membrane which offers a sustainable and affordable approach to needing both thermal and breathable insulation. Agrement Certified and accepted by NHBC, YBS BreatherQuilt has a built-in double-sided tape for ease of installation in pitched roofs.
YBS BreatherQuilt is simple to install in pitched roofs thanks to its flexibility and built-in tape. Simply roll the breathable insulation out across the rafters, staple in place, and use the tape to secure and overlap rolls of insulation. This overlapping method reduces the risk of condensation and removes the risk of thermal bridging.
This thermal breathable insulation roll has a waterproof outer membrane allowing exposure for up to four weeks. The way that this product is manufactured means it’s a perfect dual-purpose breathable insulation for reflecting heat back into a room, guarding against condensation and energy transfer, and being made with zero fibres so no PPE is needed to install YBS BreatherQuilt.

Question:
Can this be installed room side of the rafter if this is breathable? I have an old barn and was think of insulating between the rafters and then installing this before plasterboard or will I need a vapour barrier over the top again, I won't have a breathable membrane/vapour barrier on the cold side under the roof sheets as it's an existing roof.
Answer:
This is designed to be installed on the cold side of the roof, unfortunately your best if you don't have a pre installed membrane then you'd need to pull up the sheeting so this can be installed.
Question:
Is this product plastic and does it have any chemical treatment for fire on it please?
Answer:
It is a multifoil product (aluminium) and is not chemically treated for fire although has a fire classification rating of Euroclass E.
