The correct specification of intumescent air transfer grilles is critical, that’s why Lorient designed an ATG product selector tool to help select suitable air transfer grilles for various applications.

In everyday use, intumescent grilles allow air to circulate freely throughout the building; but in a fire, the intumescent expands to form a solid block that stops the fire from spreading. 

Reliable Fire Safety Solutions

Lorient intumescent air transfer grilles offer many benefits such as a reliable solid-state designWherever ventilation is needed through a fire-resisting wall or where ductwork runs through that wall – an intumescent ATG should be fitted to maintain fire compartmentation.

For cold smoke protection, it is vital to add a fire and smoke resistant air transfer grille with a control shutter – Talkback system.

Lorient intumescent air transfer grilles offer many benefits including a reliable solid-state design, that unlike conventional mechanical fire dampers do not contain any moving parts.

They are easy to install, low maintenance; and can offer fire performance ratings from 30 minutes to in excess of 180 minutes. They are also tested and approved in accordance with the very latest standards; including BS 476-22:1987 and BS EN 1364-5:2017.
