Continuous rooflights

Characteristics

  • The use of continuous rooflights allows to reduce the need for artificial lighting and thus greatly reduces the electricity bills.

  • Continuous rooflights can be equipped with a ventilation flap providing natural ventilation of facilities.

  • They are widely used in large-scale facilities, i.e., production halls, logistics centres, warehouses, sports facilities, high-rise warehouses, and shopping centres.

  • Continuous rooflights can be equipped with a smoke vent for smoke extraction.

  • They can be made in two variants: triangular or arched.

The upstand of a continuous rooflight:

The upstand is made of galvanised steel sheet 1.5 mm – 3 mm thick and 150 mm – 750 mm high. The upstand should be insulated with a layer of mineral wool, polystyrene, or PIR foam 50 mm or 100 mm thick. The upstand is mounted on a constructed supporting structure. Optionally, the base can be made in a self-supporting version with a max. 6 metres row spacing of support points.

 

Structural and cover aluminium profiles:

The structural profiles, correctly connected together with fasteners, constitute a rigid and light frame in which covers are fixed. Cover profiles are the finishing elements of a continuous rooflight.

 

Cover of a rooflight :

The cover of a continuous rooflight is made of cellular polycarbonate or cellular polycarbonate combined with a special fabric, owing to which we will receive a product that can be classified into non fire spreading class Broof (t1)/NRO.


Smoke vent or ventilation vent in a continuous rooflight:

The vent in a continuous rooflight  is an additional element. The smoke vent is activated with either a 24 V electric drive or a pneumatic drive. Ventilation function will require to supplement the pneumatic drive with an additional 230 V actuator, while the 24 V drive will suffice for both smoke extraction and ventilation. With ventilation function only just one 230 V actuator is used.

  • Width up to 6 m for arch continuous rooflights  or 4.5 m for triangular continuous rooflights

  • DL 750 – downward load resistance up to 750 N/m2

  • UL 1500 – upward load resistance up to 1500 N/m2

  • SB 300 – soft and heavy body impact 

  • 1.1-2.5 W/m2K – heat transfer coefficient for the entire product. The coefficient value depends on the choice of cover and upstand variants

  • Cover made of polycarbonate 21 mm, 27 mm, or 33 mm thick in accordance with the NRO/Broof (t1) requirements

  • Option to equip the elongated skylight with ventilation, smoke or smoke and ventilation damper

  • Option to equip with anti-fall grate and anti-insect screen

  • Option to equip elongated skylights with anti-fall grips

  • Option to use an additional E30/EI30

  • Option to paint the upstand from the inside in any RAL colour

  • Elongated skylight damper equipment with a smoke venting and ventilation system, for example smoke venting control panel, smoke detectors, alarm buttons
