Weatherproof Roof Hatch
A fully weatherproof hatch suitable for roof access is available.
Fire Resistant Casings
We can offer the Supreme with a choice of fire resistant casings:
a) the wooden hatchbox and trapdoor coated with pyroex to give a 30 minute fire resistance or
b) the steel hatchbox and trapdoor with either a 30 or 90 minute fire resistance.
The Supreme is suitable for use with suspended ceilings. When installing a deep hatchbox within a void e.g. an area between a suspended ceiling and the main ceiling, then we would recommend the use of bracing from the main ceiling to the outside of the hatchbox to add stability.
