Icopal Thermazone Roof Insulation Boards for Flat Roofs

Thermazone TorchTop Roof Insulation Boards

Thermazone TorchTop insulation board is suitable for use with Icopal Profiles and Total Torch waterproofing systems. It is suitable for use over all types of structural deck and must always be laid over a suitable vapour control layer.

Features & Benefits

  • Excellent thermal performance.
  • Dimensional stability.
  • 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 Torch Top insulation board  is manufactured from a high performance CFC/HCFC– free polyisocyanurate (PIR) based formulation with a typical density of 32 kg/m3.

Thermazone Torch Top insulation board is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).

Insulation Board Facings: Thermazone Torch Top insulation board is faced on the upper surface with an autohesively bonded, 15mm thick perlite board, manufactured from expanded, milled, volcanic perlite rock particles formed into a board and treated during manufacture with a bitumen emulsion and finished on its upper surface with a thermofusible film.

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