Frame for 1981mm x 762mm x 44mm FD30 Fire Door

Construction mirrors the style of an external frame while remaining suited to an internal location. Instead of a projecting cill typically found on external door sets, this design includes a solid hardwood threshold, creating a practical barrier between garage flooring and the home interior. That detail helps maintain a tidy transition between spaces while supporting correct fire door installation.

Every component arrives flat-packed for convenient transport and efficient handling on site. Pre-machined mortise and tenon joints simplify assembly, allowing tradespeople to achieve a precise fit with minimal preparation work. Grooves for 15 x 4mm intumescent strips are already machined into the frame, ensuring compatibility with standard fire door sealing systems once the appropriate intumescent material is installed.

Sizing

Two frame options are supplied to suit the most common FD30 internal fire door dimensions used between garages and homes.

Design & Compatibility

Homes with attached garages often require a fire-resistant barrier between the garage space and internal living areas. Building regulations frequently specify FD30 rated doors in these locations to slow the spread of fire and smoke should a vehicle or stored materials ignite.

Using a purpose-built frame is vital for achieving correct installation. The Hardwood Integral Garage Personnel Fire Door Frame has been designed with that requirement in mind, ensuring compatibility with standard 44mm thick FD30 doors and commonly used door sizes. Integrated intumescent grooves simplify the fitting of fire protection seals, while the hardwood threshold helps create a practical transition between the two environments.

This frame provides installers with a reliable, professional solution for garage-to-house access points, ensuring that fire door assemblies are supported by a structure built for the task.
