BauderJFRI PREMIUM (300) Inverted Insulation

BauderJFRI PREMIUM (300) Inverted Insulation is an environmentally friendly, high performance rigid expanded polystyrene (EPS) insulation with improved thermal conductivity. It is very lightweight and has a higher compressive strength than our Premium+ range. The product is rebated on all four sides to ensure thermal continuity. It is CFC and HCFC free, with a Global warming potential less than 5Kg CO2 Eq./kg.

This product is for use with inverted (protected membrane) roof constructions and can be laid directly onto Bauder Hot Melt and Bitumen Based Waterproofing Membranes. Contact Bauder for advice relating to other membrane types.

Use in conjunction with BauderJFRI WFRL Membrane prior to installing paving, decking or ballast or Extensive, Brown, Biodiverse or Intensive Green Roofs. Use in conjunction with BauderJFRI Upstand board or BauderROCK NC 56mm Upstand Board to exposed vertical upstands.
