Lorient's LVH44 is a high performance intumescent grille designed for doors, walls, ducts, floors & ceilings.

In everyday use, the grilles allow the free movement of air around a building. In a fire, our intumescent grilles expand to form a solid block that stops frie spreading.

In this video, we put the LVH44 to the test utilising our indicative furnace.

The footage has been accelerated for ease of viewing.

In less than 2 minutes, an effective seal is formed.
