Bauder JFRI PREMIUM (300) Inverted Insulation

Application

  • Use in conjunction with Bauder JFRI WFRL Membrane prior to installing paving, decking or ballast or extensive, brown, biodiverse or intensive green roofs.
  • Use in conjunction with Bauder JFRI Upstand board or BauderROCK NC 56mm Upstand Board to exposed vertical upstands.

Description

A rigid expanded polystyrene (EPS) insulation with improved thermal conductivity. It is very lightweight and has a higher compressive strength than the 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 of less than 5 kg 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.


Only to be used as part of a full Bauder Waterproofing System. Not for use with Bauder LiquiTOP PU System.
