| W103 (with matt, light-coloured film) | 1,1 W/(m²K) | 54 % | 59 % | 38 dB |
Ventilation drives
- 4 x 24 V linear drives, weatherproof, with control panel
- Protection class IP 65, 1 A power consumption per motor
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.
Energy efficiency
Isothermal lines indicate points featuring the same temperature and reveal a measurable customer benefit in a thermal diagram. The 10° isothermal line, for example, is a measured variable used in building physics to ensure protection against condensate. If this line wanders outside the confines of a structure, condensate or even hoar frost will form precisely at this point.
