Characteristics
Smoke vents are used to extract smoke produced by a fire
They facilitate the evacuation of people by keeping a smoke-free layer in the lower part of the facility
Smoke vents facilitate the rescue team operations
Protect the building structure
Reduce indirect losses caused by the emitted smoke and hot fire gases
Serve as skylights providing more natural daylight in the premises in which they are installed
They can also be used as room vents if appropriate actuators are installed
The upstand of the vent:
Made of galvanised steel sheet min. 1.25mm thick (straight, straight-slant or slant upstand 350 mm, 500 mm, and 750 mm high). The upstand should be insulated with a layer of mineral wool, polystyrene, or PIR foam 40 mm thick.
Made of PVC (slant upstand 300 mm high). The upstand does not require insulation because it is insulated with a layer of expanded polystyrene.
Compensation frame:
Once the upstand is fixed and finished, the special cut-outs in its corners enable easy snap-fit mounting of the PVC compensation frame.
Hinged cover:
The hinged cover consists of a frame and a cover. Covers can be made in the form of a dome (made of acrylic or solid polycarbonate) or flat (made of cellular polycarbonate). The cellular polycarbonate cover can be made in Broof (t1)/NRO classification.
The frame is made of PVC or aluminium profile. It is secured around the whole perimeter with gaskets preventing water from getting inside
Drive:
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 functions.
Single-leaf smoke vents are made in dimensions ranging from 100 cm x 100 cm up to 200 cm x 300 cm in various dimensions
Re1000 – They demonstrate operational reliability in 1000 cycles of opening and closing the smoke vent leaf to the ventilation position, 1000 cycles of activation of the trigger circuit without any loss of efficiency and efficient opening time not longer than 60 seconds.
SL250 / SL550 / SL900 – reliable operation under a load of 250 N/m2, 550 N/m2, and 900 N/m2, respectively
WL1500 – wind load resistance up to 1500 Pa
B300 – temperature resistance up to 300 °C
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
High values of smoke extraction parameters specified in the Performance Certificate 1488-CPR-0042/W
Smoke vent can be equipped with fall protection grids or/and a mosquito net
Smoke vent can be equipped with anti-grab bars
Inner side of the upstand can be painted in any colour from the RAL palette
Retrofitting the smoke vent with a smoke extraction and ventilation system, e.g., smoke extraction control panel, smoke detectors, emergency buttons
Roof skylights provide convenient lighting and even distribution of daylight
Popular application of skylights is spot lighting of workstations located directly under the skylight
Skylights with ventilation function enable natural ventilation of the rooms in which they are installed
Application of skylights helps to minimise electricity costs
They have a wide application in large facilities, as they can effectively replace traditional windows
