Design-led performance for contemporary architectural interiors
A FD30 fire-rated pocket door and jamb lining kit not only looks great it provides peace of mind
FD30-Certified Pocket and Concealed Door Systems from Rocket Door Frames
Rocket Door Frames has established itself over the past five years as a leading innovator in space-saving pocket door systems across the UK. Its fully steel pocket door kits have grown in popularity among architects, contractors and high-end residential developers, driven by robust construction, simplified installation and a clean, contemporary finish.
Alongside its pocket systems, Rocket’s ultra flush concealed door solution, designed without architraves, has become a fashionable choice for designers seeking uninterrupted wall lines and minimal visual detailing in both residential and commercial environments. But in today’s regulatory climate, aesthetics and installation efficiency must be matched by proven fire performance.
Independently Tested FD30 Performance
With fire safety now a critical factor in building design and product selection, Rocket Door Frames has invested in rigorous independent testing to validate the performance of its systems.
Both the steel pocket door system and the aluminium two-way push-pull ultra flush concealed door system were tested by Warringtonfire, a UKAS-accredited laboratory. Each system achieved full FD30 certification, confirming 30 minutes of fire resistance in accordance with UK standards.
Notably, during testing of the pocket door configuration, Rocket elected to use a flaxboard core door which is widely regarded as one of the most onerous fire door cores. By selecting this door type for assessment, the company aimed to provide specifiers with maximum confidence when ordering.
The result exceeded expectations: the system achieved 48 minutes of fire protection, delivering 60% beyond the minimum requirement for FD30 approval.
Fire-Rated Pocket Jamb Lining
Integral to the FD30 system is Rocket’s purpose-designed fire-rated jamb lining. Installed post door fit-out, the timber lining conceals the head and running gear while lining the internal steel pocket entrance for a refined, architectural finish.
Manufactured from high-density, slow-burning European oak, the fire jamb provides structural stability and enhanced fire resistance. Crucially, the system does not incorporate fixed architraves. This allows architects and developers to maintain consistent architrave detailing across a scheme, rather than being restricted by integrated frame profiles, an important consideration in high-spec residential and multi-unit developments.
The jamb system successfully passed fire testing without the need for applied architraves, reinforcing the integrity of the complete assembly.
The FD30 fire-rated jamb lining kit comes in a range of sizes: 120mm, 125mm and 140mm
