Fire-Rated Glass Partitions (EI30/EI60)

Full fire resistance without the visible frame between panes. EI30/EI60-rated, 4 mm silicone joints, no limit on overall wall length, installation quoted separately.

WH-78EI is a silicone-joined glazed wall system that removes the visible vertical profiles that normally separate the glass modules in a partition, while keeping full fire resistance. The joint between panes is just 4 mm, filled with intumescent firestop material and non-flammable silicone, in black, grey or white to match the fit-out.

Because the wall reads as continuous glass rather than a row of framed panels, rooms built with WH-78EI feel larger, while the wall still does what a fire-rated partition has to do: hold the fire compartment and keep escape routes usable.
