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 tested under EN 1634-1.

Steve Potter Owner, Form
Forza were selected as we have established a trusted relationship with them on our previous projects, based on their customer service and exceptional quality. We couldn’t be more proud of the end result, and to work with a fantastic forward thinking client.

Paul McArdle Director & Co-Founder, Imago Interiors
The craftsmanship of [Forza’s] timber doors is second to none, and the level of detail and precision made the installation process effortless and reinforced why we chose them.

Liam Greenhow Commercial Manager, Form
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. The next day their Sales Manager was in my office and within 3 days all designs and door schedules were complete. Five weeks later all 43 bespoke doors were on site.
