GEOTEC S Vertical Smoke Extraction & Ventilation Ducts

A key principle underpins the operation of fire-resistant ducts: a constant flow of air allows toxic fumes and hot gases to be rapidly extracted by fire-resistant smoke extraction ducts, while maintaining a supply of fresh air via fire-resistant ventilation ducts. This strategy limits smoke propagation, improves visibility for occupant evacuation and reduces temperature rise, thus contributing to better protection of people and infrastructure. By complying with fire safety standards, these systems guarantee effective passive protection, essential for preventing and controlling fires in buildings. Our GEOTEC® smoke extraction and ventilation ducts are a perfect example of this determination. We manufacture these systems by juxtaposing GEOTEC®S fire-resistant boards. Each board measures 1000 mm in length and is available in widths ranging from 200 to 1100 mm (in increments of 50 mm) and thicknesses of 30 or 45 mm. All fire-resistant boards are molded to standard dimensions with a rebate on all four sides for 45 mm-thick ducts, and on two sides for 30 mm-thick ducts, to facilitate assembly.
