Application

Used for insulation in:

  • External roofing – pitched, flat and complex roof structures.
  • External buildings and cold stores.
  • External oil and chemical storage tanks.

Should be built up in passes of not less than 15 mm, and should not be used on substrates below 10°C. When used externally, the foam must be protected from ultraviolet radiation and atmospheric degradation by a suitable elastomeric coating, e.g. ISOTHANE EM – consult manufacturer for details.

Description

Two-component, modified polyurethane, 1:1 ratio rigid foam system.

Features and benefits:

  • Free of HCFCs (Hydrochlorofluorocarbons) and CFCs (Chlorofluorocarbons).
  • Produces a rigid foam of 40 kg/m³.
  • High compressive strength helps to withstand damage from foot traffic.
  • Smooth surface.
  • Can be processed through all standard foam spray machines.
  • Seamless.
  • High insulation values, which helps to reduce heating costs.
  • Good adhesion to all types of surface.
  • Quick and easy to apply – no mechanical fixings required.
  • Complies with BS: 5241 and BS: 7021 for external roof insulation and weatherproofing.
  • Manufactured under ISO 9001 and ISO 14001 'Quality and Environmental Management Systems'.
