FIRE CURTAINS

Window Techs fire curtains provide up to 240 minutes (4 hours) of fire integrity — the highest rating available. Our curtains are independently tested and certified under EN 1634-1 by TÜV and Efectis laboratories, two of the most respected fire testing bodies globally.

Yes. All Window Techs fire curtains are fully compliant with the National Building Code of India (NBC 2016), Part 4 — Fire and Life Safety. They also comply with IS 16947 where applicable. Our systems satisfy the fire compartmentation requirements mandated for commercial buildings, hospitals, hotels, malls, and high-rise structures in India.

A gravity fail-safe system ensures that the fire curtain deploys automatically even if there is a complete power failure. The curtain is held in the retracted position by a motorised brake. When the fire alarm triggers — or when power is lost — the brake releases and gravity pulls the curtain down at a controlled, safe speed to seal the opening. This is a critical safety feature required by EN 1634-1 and NBC 2016.

Window Techs manufactures four types of fire curtains: the WFC standard fire curtain (single and double barrel), the WAFC-01 accordion fire curtain for wide openings, the WEFC-01 egress fire curtain which allows safe evacuation through the curtain, and the WDFC-01 draft curtain for smoke and draft control. All models are EN 1634-1 certified with up to 240-minute fire integrity.

Fire curtains are required wherever fire compartmentation is mandated but traditional rigid barriers such as walls or fire doors are not feasible. Common locations include atriums, lift lobbies, stairwells, open-plan office floors, shopping mall corridors, hotel lobbies, data centre server rooms, airport terminals, and theatre stages. Window Techs fire curtains have been installed at Google data centres, Amazon warehouses, Walmart retail stores, L&T facilities, AIIMS hospital, and Taj Hotels properties across India.

Yes. Window Techs fire curtains are fully compatible with fire alarm systems and building management systems (BMS). The control panel accepts standard fire alarm contacts and can trigger single or multiple curtains simultaneously across a building. Integration with HVAC, access control, and elevator systems is also supported.

The standard manufacturing and delivery timeline is approximately 3 to 4 weeks from order confirmation and receipt of deposit, subject to specification review by our sales team. Installation timelines depend on site conditions and scope. Our engineers provide a complete installation and commissioning service with pan-India reach.

All Window Techs fire curtains carry a 12-month manufacturing warranty covering mechanical faults. We recommend annual servicing by our qualified engineers, who test the curtain against the fire alarm, replace control panel batteries, check motor limits, and issue a Service and Maintenance Certificate. Post-warranty annual maintenance contracts are available. Once serviced, units are guaranteed for a further 12 months.

Yes. Fire curtains should be inspected and tested at minimum once per year by qualified professionals. Regular maintenance ensures the system deploys correctly in an emergency and maintains its compliance with fire safety standards. Window Techs offers annual maintenance contracts across India, including site visits, alarm testing, battery replacement, and certification.

Yes. All Window Techs fire curtains are manufactured to custom dimensions. We supply curtains for standard doorway openings as well as large-span atriums, wide lobby openings, and irregular architectural configurations. Our team reviews each project’s drawings and specifications to recommend the correct model, size, and fire rating.
