BENEFITS AT A GLANCE

ROOF EXIT HATCH COMFORT DOUBLE FLAP


The CI System Roof Exit Hatch Comfort Double Flap offers much more than an ordinary roof exit: The two-section sliding roof on an upstand (max. opening size 96cm x 282cm / top roof edge size 120cm x 300cm) will enable you to easily access the outside terrace from your stairs. This adds value to exclusive top floor apartments while indoor climates are noticeably more pleasant.

Design & Comfort

  • Generous daylight incidence
  • Convenient access to the roof terrace using the staircase (provided by client)
  • Self-cleaning thanks to partial glazing at an angle of 5° on a up stand which slopes 3° downwards on the eave side
  • Continuously adjustable ventilation position for one or both flaps
  • Sleek appearance: No interfering edges or visible drive units inside
  • Wide variety of colours based on RAL system (surrounding profile)
  • Flap system, motor opener and upstand are fully pre-assembled in the factory

ENERGY EFFICIENCY

  • Overall structure free of thermal bridges
  • Upstand thermally insulated over its entire surface
  • Optional: Functional glazing of superior quality
  • Minimised risk of condensation

Safety

  • Possible to close from the outside using an optional control unit
  • Smoke removal: Can also be used to remove smoke
  • Emergency stop during closing triggered by sensor barrier

TECHNICAL DETAILS

ROOF EXIT HATCH COMFORT DOUBLE FLAP


Construction Details

  • Head clearance needs to be taken into account when the client is planning and building the staircase
  • Two electric motors attached to the external corner section
  • Four-layered sealing system

THERMO-ACTIVE DESIGN

A patented structural ribbing uses the thermal energy of the room air below the base of the glazing. This increases the surface temperature in the aluminium frame.
The effect: Flawless isothermal characteristics and minimised risk of condensation.

ENERGY EFFICIENCY

UPSTAND – STABILITY AND THERMAL INSULATION

The upstand forms the base for the construction (top roof edge size 120 cm x 300cm). It provides a thermally optimum mount on the building structure. Manufactured by LAMILUX, using fibre-reinforced composite, our upstands are CFC-free, solid white in colour and thermally insulated with polyurethane hard foam. They include weatherproof sealing and are classified as non-flammable components with no burning droplets. LAMILUX upstands feature a closed box section, which makes them very stable and warp-resistant.

The continuous insulation, which is at least 55mm thick, provides an excellent heat transition coefficient U of 0.6 W/m²K. The upstand is 40cm high on the eave side and climbs at an angle of 3° to reach a height of 55cm on the ridge side. This ensures optimum self-cleaning on all sides of the structure.
