BauderJFRI (300) Inverted Insulation

BauderJFRI (300) Inverted Insulation is an environmentally friendly, high performance rigid expanded polystyrene (EPS) insulation, which is very lightweight and has a higher compressive strength than the (200) grade. 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. 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.

Intended Use

Use in conjunction with BauderJFRI Vapour Permeable Membrane Layer (WFRL) prior to installing paving, decking, ballast or green roof. Use in conjunction with BauderJFRI HP Plus 60mm Upstand Board to exposed vertical upstands.
