Insulation | |
Type | Proteus Pro-Therm PIR.Guidance for specification option: Proteus Pro-Therm Insulation PIR is a fibre-free rigid polyisocyanurate (PIR) insulation core faced with coated glass tissue on one side and bituminized glass tissue with polypropylene fleece on the other. The PIR fibre free insulation core is temperature tolerant and withstands the application of hot bitumen and asphalt to the surface at up to 230°C. Proteus Pro-Therm HP PIR.Guidance for specification option: Proteus Pro-Therm HP PIR used either stand alone or with tapered or flat board insulation as a premium performance board, providing a slim solution for use on new and existing roofs with timber or concrete decks. Proteus Pro-Therm HP PIR Plus.Guidance for specification option: Proteus Pro-Therm HP PIR Plus used either stand alone or with tapered or flat board insulation as a premium performance board, providing a slim solution for use on new and existing roofs with timber or concrete decks. Proteus Pro-Therm Mineral Wool.Guidance for specification option: The Proteus Pro-Therm Mineral Wool has been specifically developed for use on flat roof and refurbishment projects. The product is manufactured with an integral mineral coating fibre fleece, which for adhered membranes, secured a strong bond between membrane and insulation whilst limiting the amount of adhesive required. The insulation is compatible with all commonly used flat roof membranes including bitumen and liquid applied membranes. Proteus Pro-Therm Cellular Glass.Guidance for specification option: Proteus Pro-Therm Cellular Glass consists of a Cellular Glass slab, the upper surface is unfaced. The insulation is manufactured from specially graded recycled glass (≥60%) and natural raw materials which are available in abundant supply (sand, dolomite, lime). The product is totally inorganic, contains no ozone depleting propellants, flame resistant additives or binders. Without VOC or other volatile substances. Proteus Pro-Therm VIP.Guidance for specification option: Proteus Pro-Therm VIP Insulation is a high performance Vacuum Sealed Insulation Panel with a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope, giving outstanding thermal conductivity, with the thinnest possible solution to insulation problems, suitable for a variety of roof types and designs.
