Upstand - Stability and thermal insulation

The seamlessly manufactured upstand (top roof edge dimensions 120 x 300 cm) forms the base for the construction. It provides the ideal thermal connection to the building structure. The LAMILUX upstands made of glass-fibre 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. LAMILUX upstands have a closed box cross-section - this makes them very stable and torsion-resistant.

The continuous insulation, at least 55 mm thick, ensures an excellent heat transfer coefficient of 0.6 W/m²K. The upstand is 40 cm high on the eaves side and rises by 3° to 55 cm on the ridge side. This supports the self-cleaning of the element.
