Permatuff MD R1.3 55MM x1200mm x 15m Roll

Fletchers Permastop® Building Blanket is a glasswool insulation blanket with one side factory-faced with Sisalation® reflective foil laminate that is non-permeable to moisture. A 150 mm foil lap is provided for seam sealing.

It helps control condensation under metal roofs, behind wall cladding, or beneath concrete roof structures by acting as both a vapour barrier and insulation layer. The blanket also reduces heat transfer into the building, lowering cooling or heating loads, and provides acoustic damping to reduce noise from rain, hail, and vibration.

Permastop blankets are installed with the foil facing downwards (towards the interior) so that the blanket lies in contact with the underside of the roof. All joints in the foil should be sealed using suitable tape to maintain continuity of the vapour barrier.
