Gilberts has risen to the challenge of ensuring the balance of ventilation and safety with the development of its fire rated connection box (plenum).
The Fire Rated Connection Box (available in both top and side entry versions) achieves 60 minutes’ fire and thermal rating to EN1366-3-2021. It means that fire integrity of ventilation between internal compartments has never been easier to achieve.
The new plenum maintains performance integrity when tested at temperatures up to 1000°C. It ensures that the fire barrier through a masonry or plasterboard wall or ceiling or concrete floor will be retained, maintaining compartmentation.
Gilberts believes it is the only plenum of its kind in the UK tested to deliver such high performance. It gives assurance that the two relevant layers of fire safety- compartmentation and structural safety- are addressed.
“There is no harmonised European standard for fire testing of plenum boxes.However, it is the crucial element in retaining the fire compartment. The lack of a definitive Standard makes it difficult for fire officers to sign off a detail. By providing them with a tested one- hour fire and thermal rated plenum box they have the peace of mind that they have a sensible choice,” explains Gilberts’ Technical Director Roy Jones.
“We believe it will be the ‘go to’ solution for consultants and contractors to achieve building compliance in non-domestic or multi-occupancy settings.”
The Fire Rated Connection Box builds on Gilberts’ reputation as an innovator committed to giving clients products that exceed expectation.
All Gilberts’ products, standard lines and bespoke solutions, are designed and developed in accordance with BS EN ISO 9001:2015 quality standard in the company’s state of the art 140,000 ft2 facility in Blackpool.
