Stick system

Our stick-glazing system enables you to create individual, creative and tailor-made daylight and ventilation solutions with very good physical building properties.

The thermally broken stick system consists of aluminium profiles, vertical mullions and horizontal transoms that are assembled on site. Vertical and horizontal aluminium profiles are fitted with EPDM gaskets. Externally, the profiles have aluminium covers and pressure profiles fitted with EPDM gaskets that retain the insulating glass units in place.

Profiles are self-supporting and carry the structural load of the glazing solution. If required, the profiles can also be fixed to a steel, concrete or wooden sub-structure. The mullions and transoms have a 60 mm profile width. The height of the profiles can be between 35 mm and 190 mm and is determined by the span width, taking the solution self-weight and external loads into consideration.

The system offers excellent sealing values even for low pitch roof slopes and a controlled and reliable drainage over two levels.

Guaranteeing both products and installation, we manufacture, deliver and install the glass roof solution.

The stick-glazing system provides almost unlimited design freedom when it comes to sizes. The profile height is dimensioned between 35 mm and 190 mm according to span width, taking the solution self-weight and external loads into consideration.

The complete solution is statically calculated by our engineering specialists and verified by the customer depending on the use and building situation.

VENTRIA flaps are available for comfort and smoke ventilation, including dual function of both comfort and smoke ventilation.
VENTRIA TG flap and VENTRIA 3 flap, constructed from high-quality aluminium profiles, can be used as both top-hung and bottom-hung solutions for daily comfort ventilation and as a bottom-hung solution for certified smoke and heat exhaust ventilation CE-marked according to EN 12101-2.
Flaps can be installed as a single or as a double flap using either electrical (24 V or 230 V) or pneumatical operation. However, flaps for smoke ventilation can only be electrically operated.

Stick System ventilation flaps have a recommended minimum installation height of 2.5 m above floor level (inside) and ground level (outside). In case of installation of the ventilation flaps below that level, safety measures must be applied by the user to prevent serious injury.

By ordering a stick system solution containing ventilation flaps to be placed within reach i.e. below 2.5 m above floor/ground level, delivered and installed by the VELUX Group, the user acknowledges to have been made specifically aware of the regulatory requirements concerning entrapment protection and inherent hazards, and the user takes full liability on application of adequate safety measures. No instruction or measure can eliminate the inherent hazards resulting from installation heights below 2.5 m. Measures could for instance be to install a motion sensor that is able to disconnect power from the control unit in case of any movement in the immediate vicinity of the Stick System ventilation flaps.

The mullions and transoms have a 60 mm profile width. The height of the profiles can be between
35 mm and 190 mm and is determined by the span width, taking the solution self-weight and external loads into consideration.
The mullions and transoms are fitted with EPDM gaskets. Externally, the profiles have aluminium covers and pressure profiles fitted with EPDM gaskets that retain the insulating glass units in place.

Continuous insulation strips made of XPS foam placed between the glazing units combined with the EPDM gaskets provide an advanced thermally broken system.

Sealed variant is an alternative design option, which is ideal for low installation pitches. This variant is sealed to ensure water tightness and mechanically fixed with stainless steel suction plates every 300 mm instead of cover profiles.

The roof glazing system can be designed with the following options to ensure optimal indoor comfort:

• Glass thickness between 25 mm and 60 mm
• Insulating glass unit with Ug values down to 0.5 W/m²K
• Fall-through safe glazing
• Toughened outer glass
• Laminated inner safety glass
• Sun protection coating
• Printed glass
• Photovoltaic glass

The system has an abZ technical approval (allgemeine bauaufsichtliche Zulassung) Z-14.4-486 from the German technical building authorities, and the flaps for smoke ventilation are CE-marked according to EN 12101-2. Additionally, the system and the VENTRIA 3 flap has an Environmental Product Declaration (EPD) according to ISO 14025 and EN 15804.

The system can be offered in a highly thermally insulated design as passiv house standard (Passive House Institute No. 0538ic03). This product is not compatible with flaps for comfort or smoke ventilation.
