Acoustic Doors FAQs

Can you cut aperture holes on a flush door leaf on-site?

Letterbox, door viewer, air transfer grills must be tested or otherwise approved for use with Forza fire-rated doors, they must be fitted fully in accordance with manufacturer instructions including all intumescent liners and cloaking grilles/beads.

Restrictions on the maximum size and placement of any aperture, in which must also be included in the total area permitted for apertures.

Note: the installation of such items in a door leaf may compromise its performance as a smoke control door assembly.

I need EN tested doors, are your doors EN tested?

At this moment Forza is only permitted to certify fire-rated door assemblies under BS 476: 22.

We are actively developing a scope of fire-rated products under EN 1634-1.

  • Forza's service and quality went above and beyond our expectations. After having trouble with another door manufacturer we approached Forza Doors and explained we had 8 weeks left on programme.
