Applications

PYROGRILLE units can be fixed into fire resisting doors or timber stud partitions using a hardwood or steel flange. Alternatively wood screws can be used through the perimeter of the units.

Gaps around the PYROGRILLE unit greater than 3mm should be fire sealed using PYROMAS A intumescent sealant.
