Somerset based premium ready meal producer, Charlie Bigham’s, required a new production facility as part of their continuing expansion plans. The original building design specified standard, non-fire rated vison panels with automatic fire rated shutters to close off the openings in the event of a fire. This solution required complicated and costly controls and additionally, the surface-mounted shutters would create ledges and inaccessible areas that were not suitable for hygienic environments.


Turnkey technical contractor TSL required a cost-effective alternative to the proposed fire rated window solution that would maintain the fire rating and hygienic requirements for a food manufacturing facility.  Having worked with MIDDAS previously on other projects, TSL turned to the team for a viable solution.


MIDDAS designed and manufactured a solution from its wide range of independently tested, flush triple-glazed vison panels.  The vision panels are designed so the outer glazing of the cassette finishes flush with the walls, ensuring a hygienic, wipe-clean surface.  The third inner pane of the triple glazed vision panels provided the fire barrier.

MIDDAS vision panels are engineered to integrate into any third party wall type, including fire rated walls supplied and installed by others, negating the need for the originally proposed fire shutters.

MIDDAS understood the brief and were able to offer a proven and tested solution to meet our requirements for hygienic fire rated vison panels. MIDDAS worked closely with our installation and design team to engineer all the interfaces and the result met all our expectations including a cost saving over the original design intent.
