What Should Be Considered for Roof Windows and Skylights?
Transparent roof components must be designed as a complete system. In addition to selecting the appropriate sheet, the substructure, support spacing, fastening, sealing, drainage and thermal expansion are critical factors. Wind and snow loads, maintenance loads and local building regulations must also be taken into account during planning.
- Determine wind and snow loads as well as the required spans.
- Allow sufficient movement clearance for thermal expansion.
- Use suitable profiles, seals and fastening systems.
- Plan roof pitch, drainage and controlled water runoff.
- Properly protect sheet edges and connections against moisture.
- Check local building, safety and fire protection requirements.
FAQ About LEXAN™ Film & Sheet for Roof Windows and Skylights
Which LEXAN™ Film & Sheet Product Is Suitable for Roof Windows and Skylights?
For transparent roofing applications permanently exposed to weather conditions, a UV-protected product grade designed for this purpose, such as LEXAN™ EXELL™-D, is particularly suitable. Specific suitability must be assessed based on the technical product data and the construction.
Why Is UV Protection Important for Transparent Roof Surfaces?
Roof windows and skylights are exposed to intense sunlight and weather conditions. For such applications, a LEXAN™ Film & Sheet product grade specifically designed with UV protection should be selected.
What Sheet Thickness Is Required for a Skylight?
The required sheet thickness depends on factors including dimensions, support spacing, installation position, wind and snow loads and the fastening system. It must therefore be determined for the specific construction.
Can LEXAN™ Film & Sheet Products Be Used for Curved Skylights?
Depending on the product grade, sheet thickness, bending radius and type of construction, curved applications may be possible. The permissible parameters must be obtained from the relevant technical documentation.
What Must Be Considered When Fastening Polycarbonate Sheets on a Roof?
Polycarbonate changes dimensions as temperatures fluctuate. Fasteners, drill holes, profiles and joints must therefore allow sufficient movement while also providing a secure and permanently weather-tight construction.
