OWS Ltd are able to offer a complete design, manufacture and installation service for fire rated products from our factory in Surrey where we have been producing high quality windows, doors and curtain walling for more than 10 years. We use the latest CNC cutting and machining equipment so that we can offer a fast turnaround from drawings to finished product at extremely competitive prices.

As a matter of policy we undertake to employ environmentally sympathetic materials and processes wherever feasible. Nearly every component that is used to make our MB78 EI fire rated doors and screens comes from a sustainable source, all aluminium, steel, thermoplastic rubber seals and polyamide strips are 100% recyclable.

Aluminium is now more than just a cost effective alternative to steel and timber for fire rated doors and windows - it provides real advantages in design, fabrication and installation. Our products are architecturally pleasing in both internal and external applications, and can achieve fire rated values of up to 120 minutes integrity and insulation, conforming to European standards.

Aluminium profiles and components can be powder coated prior to assembly, dramatically reducing manufacturing lead times and producing a low maintenance, attractive, durable finish that withstands the harshest environments and climatic extremes. The resilience and versatility of aluminium makes it an ideal choice for installations of up to 4000mm screen height in practically all applications where fire rated doors and windows are needed.

The MB-78EI system conforms to the following standards:

  • EN 1364-1
  • EN 13501-2
  • EN 1634-1
  • EN 1834-3
