In cooperation with our Norwegian partner Mil Sec Norge we completed the security-up grade of a historical public building in Oslo this summer.
A large mullion-transom façade has been completely replaced by a security façade from SÄLZER. The arched windows should not be substituted for historical reasons. To upgrade the level of security secondary windows were installed inside in front of the existing window.
