Please note, delivery time is 3-4 weeks, as this product is purpose built and manufactured.


The EN1364-2:1999 classification involves challenging simulated tests. The Em-Glaze FR30 was subjected to fire conditions with temperatures reaching 600°C after 5 minutes and 840°C after 30 minutes. The rooflight withstood this for more than 30 minutes, with heat transfer kept under the allowable 180°C.

The secret to this outstanding performance is its construction: a 19mm fire resistant laminated pyro-glass inner pane and 6mm toughened glass outer pane, held securely within a well-engineered steel frame.


Always installed to a builder’s upstand to the project’s specific specification/as specified by others.
