GRP Upstand

Stability and thermal insulation in many models

The upstand forms the base for construction. It provides a thermally optimum attachment on the building structure. Manufactured by LAMILUX, using fibre-reinforced composite, our upstands are CFC-free, solid white in colour and thermally insulated with polyurethane hard foam. They include weatherproof sealing and are classified as non-flammable components with no burning droplets. LAMILUX upstands feature a closed box section, which makes them very stable and warp-resistant. Different metal inserts can be directly laminated into the structure. Secure anchorage for fittings and personal protective equipment (PPE) is guaranteed.

LAMILUX upstands can be manufactured in an extensive range of variations with regard to height and inclination angle. They also offer many options for customised roof mounts. Example: Thermally insulated base flange – variable insulation thicknesses also available on request.

DIN 18234 – Prevention of fire spread on flat roofs

The GRP upstand and the aluminium surrounding frame profile render further safety measures unnecessary on flat roofs. Surface protection in the form of gravel fill is not required.
