Smoke and Head of Stair ventilators

Colt Express Works is a specialist division of Colt International UK, providing smoke ventilators, access hatches and head of stair ventilators on an express shipping service.

Is your building compliant with building control?

Smoke control systems are required in multi-storey residential buildings, principally to protect the stairs to assist escape in the event of a fire, in compliance with the recommendations of Approved Document B and BS 9991:2011.

Often, a head of stair smoke ventilator is required to make a building compliant to these recommendations, with no additional smoke control design needed. Colt Express Works can provide these ventilators as single units, dispatched quickly with secure online payment options.
