Aluminium Foil Membrane Vapour Barrier and Thermal Insulation 1m x 50m - 50 SQ/M

Our aluminium foil membrane is a three-layer aluminium, silver foil insulation, a high-quality building supply option, which is used extensively in both new-build constructions and renovations.

Serving as a fully waterproof vapour barrier and thermal insulation upgrading system, this foil insulation is utilised in walls, roofs, attics, ceilings and floors.

Typically used in applications to minimise the thickness of the insulation required. In the best cases, the use of a foil membrane could reduce the amount of insulation needed by between 10-20mm (but typically 5-10mm), although this varies with construction type and target U-value.

Installation uses include:

• Floors – under floor boards, carpets / vinyl, tiles and laminate floor and between floor joists
• Underfloor Heating - under heating pipes (wet and dry systems)
• Ceilings – between ceiling joists
• Roof – can be used in ventilated and non-ventilated roofs
• Walls – in dry lined stud walls and against solid walls

The product can also be used in conservatory, steel, timber frame and modular construction. Please note, this membrane is not self-adhesive, it must be fixed in place to ensure its full effectiveness as a thermal waterproof insulation. Self-adhesive foil tape is available for this purpose which can be purchased on our site separately see the recommended products on this page.

The shiny side of this product should face in-towards the room when installed.
