An intumescent louvre grille measuring 150 x 300mm with a silver louvre face, combining fire-rated air transfer performance with a decorative louvre finish. The larger rectangular format provides a greater ventilation area for fire-rated doors and partitions where higher airflow is required, while the intumescent material expands under heat to seal the opening and maintain fire integrity.

Supplied as a single grille.
