  • High compressive strength.
  • Resistance to mould and microbial growth.
  • Resistant to most oils, greases and adhesives (except those containing ketones and esters).
  • Easy to handle, cut and install.

Insulation Board Core & Facings

The Core: Thermazone Full Bond Pour and Roll insulation board is manufactured from a high performance CFC/HCFC– free polyisocyanurate (PIR) based formulation with a typical density of 32 kg/m3.

Thermazone Full Bond Pour and Roll insulation board is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).

Insulation Board Facings: Thermazone Full Bond Pour and Roll insulation board is faced on the upper surface with an autohesively bonded, 13mm thick perlite board, manufactured from expanded, milled, volcanic perlite rock particles formed into a board and treated during manufacture with a bitumen emulsion.

The underside of the insulation core is faced with a perforated glass reinforced cellulose facing autohesively bonded to the insulation during manufacture.
