Key Features & Applications

  • Euroroof Caltech is a flame-free, BBA approved, fully warranted system with a life expectancy of up to 25 years
  • It can be used to refurbish failing roof coverings or to provide waterproofing for new-build podium decks, balconies and walkways. It can also be used under green roofs and is suitable for pedestrian traffic 
  • The Caltech system is fully adhered for a durable, yet flexible monolithic waterproofing solution and offers excellent resistance to puncture, abrasion, micro-organisms and chemical agents 
  • Euroroof Caltech has the appearance of a smooth, plain colour with mid-sheen finish

Durability

  • Euroroof Caltech is reinforced with a chopped strand emulsion bound fibreglass fabric to ensure excellent mechanical properties and dimensional stability, maximising durability.

Performance

  • Euroroof Caltech is a cold-applied liquid polyurethane with a high solids content. With embedment of the fibreglass reinforcement, the liquid bridges over undulations, fissures and vulnerable points within the existing roof, forming a seamless waterproofing membrane.
  • Euroroof Caltech, when tested in accordance with BS 476-3:1958/2004, achieved the highest available EXT.F.AA rating and can therefore be used without restrictions according to the Building Regulations.

Insulation

  • Euroroof Caltech is compatible with PIR insulation (warm roof) and extruded polystyrene (inverted roof)

Installation & Maintenance

  • Installed by a nationwide network of Euroroof Caltech registered contractors
  • Euroroof Caltech is a flame-free system and as such is cold-applied using roller or airless spray
  • A range of primers are available for adhesion to substrates such as concrete, metal, plywood, existing roof membranes
