Case study - Blast proof windows

We were asked to design and manufacture very heavy duty window fittings for blast proof windows that would be capable of resisting a 50 year exceptional weather event.

After extensive testing at the Building Research Establishment Watford we produced a design that passed some of the most rigorous testing we have ever undertaken. The products also had to be completely Tamperproof so that only authorised personnel could release them.

This development really illustrates what this company is all about. We have a "can do" approach to the two most important areas, solving design problems, and manufacturing specials to the highest standards.
