Smoke Curtain
Smoke Curtain: It’s management is complex and can often impact on your building’s aesthetics and interior designs. At Window Techs, our commitment to advancing smoke curtain technology has led us to develop a wide range of BS, DIN, EN and tested to UL standard smoke curtains that enable designers to make open plan environments by replacing smoke-rated walls, bulkheads, glazing and down stands with approved smoke curtains.
From the additional wide vertical smoke curtains installed to compartmentalization Pragati Maidan, ITPO, Delhi. We’ve installed 80meter wide and 16meter tall curtains.

Frequently Asked Questions
Are you looking to achieve ‘Smoke control’?
Are you using the Acceptable Solutions?
The Acceptable Solutions define smoke separations as complying with BS EN 12101 Part 1, Specifications for smoke barriers (which includes fixed barriers), or being a ‘rigid element’, and forming an ‘imperforate barrier’. It does not specify a generic acceptable air leakage rate. BS EN 12101.1 includes note 4.1 that states… compliance, by itself, does not ensure fitness for purpose for an application.
Do you need insulating capabilities?
Conventional fire curtains do not provide insulation in the traditional sense, partly because the required test thermocouples will not adhere to the curtain. In some BS EN tests irradiance is measured and this data can be used by the Fire Engineer to calculate the impact of radiant heat at given distances. (insulating zone).
What installation, inspection, testing and maintenance provisions have you made?
Curtains are often in hard to access and concealed locations. Regular operation, and access to ceiling voids for maintenance may be required.
Have you considered air flow?
Smoke curtains don’t have side guides (unless specified), so will billow out of the wind path and your smoke flow modelling will need to take this deflection into consideration. The lower the curtain descends, the greater the impact.
Fire curtains will have side guides but aren’t designed to deal with wind loads.
The curtain could also be a long way from the ultimate exit, but consider the impact of open exterior doors during the evacuation. Will airflow become channelled through the building?
BS EN 12101 Smoke and heat control systems Part 1: Specification for smoke barriers, provides some guidance on determining the effect of air flow on curtains.
