Manufactured with vapour-tight, gas-tight aluminium foil facings, FR\/ALU delivers excellent thermal performance while helping to reduce heat loss and improve the overall energy efficiency of flat roof constructions.\u003c\/p\u003e\n\u003cp\u003eSuitable for use on timber, metal and concrete roof decks, Unilin FR\/ALU boards provide a durable and lightweight insulation solution for both new build and refurbishment projects. The boards offer outstanding thermal efficiency with a low thermal conductivity of 0.022 W\/mK, helping to achieve demanding building regulation requirements whilst minimising roof build-up thickness.\u003c\/p\u003e\n\u003cp\u003eEach board measures 2400mm x 1200mm and is supplied in full pack quantities only. Available thicknesses range from 25mm to 150mm, allowing the correct specification to be selected for a wide range of flat roofing applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e Unilin FR\/ALU is designed for use beneath mechanically fixed single ply membrane systems and is not suitable for use with built-up bituminous roofing systems, torch-on felts, mastic asphalt or liquid applied roofing systems.
