Vario Therm

Vario Therm is a barrel-vault continuous rooflight that offers energy efficiency and robust construction. It combines thermal insulation, protection and weathertight roof sealing with an attractive appearance, making it the perfect choice for projects with high architectural demands.
With thermal decoupling and thermal insulation of the eaves area and kerb head, Vario Therm rooflights are able to achieve Uw-values as low as 1.02 W/m²K.
They are ideal for both new-build and refurbishment projects where sustainability and energy efficiency are priorities, and guarantee optimum roof illumination with natural, diffused daylight.

Multiple configuration possibilities are available, ensuring the right fit in every roof opening. In addition, a variety of accessories and features can be incorporated into the rooflight system, and the customised rooflights are prefabricated at our factory for easy and quick installation.

• A wide range of glazing types fulfill thermal, photometric and other special requirements as needed.
• Equipped with corresponding flap systems and opening devices, the Vario Therm rooflight can be optimally used for comfort ventilation as well as smoke and heat exhaust ventilation (SHEV).
• Fall-through protection systems ensure maximum safety during installation and when maintenance work is being carried out. Options range from lightweight systems that can be retrofit to existing rooflights, through to up to extremely robust multifunctional systems.
• Other accessories include adjustable upstands, secure roof membrane connections and intelligent building management systems.

Vario Therm continuous rooflights feature a high-quality and robust construction with excellent thermal efficiency. The innovative composite profile comprises a rigid PVC multi-chamber insulation structure and aluminium cover profiles.
This, combined with the thermal-insulating kerb system and the kerb connection profile, ensures optimal isothermal characteristics and minimal heat loss.

• Available in widths of 1200mm to 11340mm, and in any length.
• U-values as low as Uw=1.02 W/m²K.
• Great selection of accessories, including adjustable upstands, connection. systems and insect protection.
• European Technical assessment (ETA)-16/07 10.
• Smoke and heat exhaust tested according to DIN EN 12101-2.
• Meltable and can therefore be calculated as a heat exhaust surface in accordance with DIN 18230.
• Structural dimensioning according to Eurocode.

Vario Therm has an extensive selection of glazing types with the following features:

• Different thicknesses in opal or clear polycarbonate
• Thermal transmission: Ug-values from 1.80 to 1.16 W/m²K
• Light transmission from 64% to 20%
• Solar energy transmission: g-value from 15% to 54%
• Airborne sound insulation up to 21 dB
• Specialist glazing for specific needs: IR-control for lower heat input, fire class B-s1,d0, B_ROOF(t1) for resistance to external fire exposure or hail protection
