Sleek appearance, high stability: Our roof lanterns are designed for modern flat roof architecture – with slim profile views and a structural design that simplifies installation and supports watertightness.

Profile Geometry & Design

• Slim rafters (e.g., 40 mm profile width – depending on the design)
• Reduced interior view due to optimized geometry (compared to many alternatives)
• Proportionally harmonious roofline with clean lines for contemporary architecture

Load-bearing Capacity & Safety

• Robustly constructed (e.g., up to 3.5 kN/m² uniformly distributed load – design-dependent)
• Ring beam/support frame as a system component – reduces dependence on the on-site upstand
• Mechanically secured connection (e.g., pressure plate system) for robust clamping and lasting hold

Thermal Protection (depending on glazing)

• Thermal break in the profiles – reduces cold bridges
• Very good insulation values possible – specific U-values are product/design-dependent

Warranty (DE): For roof lanterns from SARIS's own production, a 10-year manufacturer's warranty applies according to the warranty conditions (see warranty page for details).

For your rooflight to fit exactly, dimensional reference, upstand, and roof sealing are crucial. The following points will help with planning and installation – without PDF downloads.

Correctly understanding dimensional reference

• Order dimension refers to the defined system/light opening (product-dependent)
• External dimensions can be constructively larger (overhangs/profile structure)
• Plan tolerances for substructure and sealing

Upstand & slope

• Recommended: Upstand at least approx. 150 mm above roof level (project-specific)
• Ensure sufficient slope to avoid standing water
• Execute the top of the upstand even/flat (prepare the support surface cleanly)

Sealing & connection

• Prepare surfaces to be dry, dust-free, grease-free
• Choose sealing system (e.g., EPDM/bitumen/foil) on-site to match the roof structure
• Installation/sealing always according to trade rules for roofers or manufacturer specifications

Note: Screws/fasteners and on-site sealing membranes are – depending on the roof structure – not automatically included.

We deliver your roof lantern free of shipping costs throughout Germany. Delivery is made via specialized freight forwarders/logistics with notification (by phone/SMS) – if available from the service provider.

Delivery times (estimated)

• Standard sizes / Stock items: usually 10–14 working days (depending on design and capacity utilization)
• Custom-made designs / Individual sizes: usually 3 to 6 weeks (after technical clarification/approval)

Delivery & Unloading

• Delivery usually takes place curbside
• Unloading on site: Please provide sufficient helpers and suitable unloading aids (e.g. pallet truck/forklift) – depending on size/weight
• Goods must be accessible at the time of unloading (consider access road/parking area/surface)

Important notes

• Please check goods for transport damage upon delivery and note any damage directly with the driver
• In case of non-acceptance/unavailability, additional costs (e.g. second delivery/storage) may arise
