Unifoil is a multi-layer bubble film insulation with an aluminium coating bonded to its face. The aluminium is coated with polyethylene which gives a corrosion resistant fully waterproof insulation system.
Unifoil is a high performance material, tested by BSRIA (Building Services Research & Information Association) to prove its efficiency, which acts by trapping air within its structure, creating low emissive air spaces to enhance its total thermal capabilities. For use on intermediate timber suspended floors, with 50mm x minimum 160mm deep (for 20mm notching) joists at 400mm centres and chipboard T & G flooring/decking. The Unifoil system is not suitable for ground floor timber suspended floors with ventilated voids.
