Retrofitting security concept

Secondary windows can provide additional levels of protection against forced entry, ballistic attack and blast when the fitting of a new up rated primary window may not be deemed suitable due to the constraints often placed upon architects / designers by either clients or planning authorities.

By installing secondary windows the outward appearance of the building is maintained whilst at the same time upgrading the level of security to any perceived threat, thus offering protection to the occupants and contents.
