Risk Assessment


We can work directly with specifiers, clients and security consultants/risk assessors to help identify the risks and specify the appropriate solutions.

Protection against forced entry may be required for a whole building or only for specific areas - in either case we can bring our experience to bear and provide the right products.




Safety Solutions


Three steps to improving window security


  • Make your property more secure than neighbouring properties, thereby making it less of a target - window security is the number one priority
  • Anything that makes it more difficult, time consuming or noisy to gain entry is both a deterrent and also makes it less likely that a thief will successfully gain entry
  • If your property is occupied, then the more warning you have from the noise the more time you have to respond - call the police and lock yourself and your family into a bedroom




Safety Testing


We offer testing on a project by project and product by product basis once the specifications have been determined.

Testing is generally carried out at the British Board of Agrément in Garston, Hertfordshire, to the following Standards:


  • BS 7950 - 1997 Specification for enhanced security performance of casement & tilt/turn windows for domestic applications
