Flat board
Torch-on roof insulation.
Application
- Suitable for use with Icopal Profiles and Total Torch waterproofing systems, and other traditional partial bond torch-on systems.
- Suitable for use over all types of structural deck and must always be laid over a vapour control layer.
- Adhesives containing such solvents should not be used in association with this product.
Description
Torch-on polyisocyanurate (PIR) based roof insulation.
Features and benefits:
- Facing: Faced on the underside with a mineralized glass tissue auto-adhesively bonded to the insulation core during manufacture. The top surface is finished with a bitumen-coated glass tissue finished with a thermofusible polypropylene fleece.
- Core: Manufactured from a high-performance CFC/HCFC free polyisocyanurate (PIR) based formulation with a typical density of 32 kg/m³. Manufactured without the use of CFCs/ HCFCs and has zero Ozone Depletion Potential (ODP) and a low Global Warming Potential (GWP).
- Compressive strength: Typically, the compressive strength exceeds 150 kPa at 10% compression and 125 kPa at 5% when tested to BS EN 826:1996.
- Water vapour resistance: Modified to include board facings, the board achieves a resistance greater than 15 MN·s/g when tested in accordance with ‘BS 4370-2:1993 (Methods of test for rigid cellular materials. Methods 7 to 9)’. Thermazone Torch-on Board must be laid over a vapour control layer.
- Durability: When correctly applied has an indefinite life. Its durability depends on the supporting structure and the conditions of its use.
- Resistance to solvents, mould and vermin: The insulation core is resistant to short term contact with petrol and with most dilute acids, alkalis and mineral oils. The insulation core is not resistant to some solvents, e.g. ketonic solvents; such as methylethylketone (MEK).
- CE marked (EN 13165, 13, 1486).
Thermazone XtraFall Taper System:
- A Thermazone XtraFall Torch-On System provides the designer and contractor with a precise, technically excellent solution to providing thermal insulation and bespoke drainage on a flat roof.
- A Thermazone XtraFall Taper System comprises factory laminated boards and factory cut hip and valley pieces which allow for the creation of mitres without on-site cutting thereby reducing installation times, cutting errors and the associated labour and waste costs. Each component is clearly identified by board type and the direction of fall.
