Upstand - Stability and Thermal Insulation

The base of the system is a seamlessly manufactured upstand that provides an ideal thermal connection to the building structure. LAMILUX upstands made of glass-fiber reinforced plastic are CFC-free, completely pigmented white and thermally insulated with rigid polyurethane foam. They have a weatherproof seal and are not considered to be burning drips and comply with DIN 18234 without additional measures. To make them very stable and torsion-resistant, LAMILUX upstands have a closed box cross-section.

The continuous insulation, at least 55 mm thick, ensures an excellent heat transfer coefficient of 0.6 W/m²K. The upstand is 35 cm high on the eaves side and rises by 6° to 68 cm on the ridge side. This supports the self-cleaning of the element.
