VRS Mono Pitch Roof Light
Construction:
Constructed using VRS roof glazing panels the VITRAL mono pitch rooflight is a double glazed system that can incorporate a wide range of glass specifications.
The rooflight can have every second panel as outward opening panel, with no visible difference in sightlines between fixed and opening panels.
Opening panels can be fitted with a range actuators and control systems to allow comfort and/or smoke ventilation. Each panel spans freely between head and cill, secured at the head with a hinge and at the base with brackets; onto a shaped cill. Frame width 48mm.
Measurements and pitch:
- Slope, glass roof 15° - 60°
- Module Measurements 270 < 1200mm
- Panel height up to 3200mm
- Panel size, see 2.4.08
Top-hung outward opening:
- Opening angle up to 45°
- The panel next to a glazed gable or hip must be fixed
Bottom-hung outward opening:
- Opening angle up to 0° - 45° from the plane of the glazing
- Always placed between to fixed panels
- Slope, glass roof 25° - 60°
- Module measurements 450 < 1200mm
Gable models:
- Vertical glass gable constructed in 1, 2, 3, or 4 VITRAL VRS panels with sloping top frame. Panels secured to gable profile and cill.
- Slope, glass roof min. 25°
- Angle with roof footing, in the horizontal plane, must be 90°
- Hipped glass gable ends constructed in 1, 2, 3, or 4 VITRAL VRS panels with sloping top frame. Panels secured to hip profile and cill.
- Angle with roof footing, in the horizontal plane, must be 90°
- Slope, glass roof min. 25°
- Both glass roof surfaces must have the same angle of slope
- Panel width must be the same on either side of the hip
Valley:
- 90° corners constructed in 1, 2, 3, or 4 VITRAL VRS panels with sloping bottom frame. Panels secured to valley and head
- Both glass roof surfaces must have the same angle of slope
Valley:
Multi tier rooflights of up to 3 tiers can be constructed using a stepped purlin arrangement. The strength of each tier should be considered in isolation, i.e. as a single tier mono pitch.
