Security & Performance
The high specification Winkhaus locking systems come designed for optimum security with the door set certified to Secured by Design, subject to configuration. Also fitted to the lock is a 3-Start security cylinder designed against picking, drilling or snapping. The door hinges also come with high security fixings with built-in security features.
Glazed door panels offer an extra layer of security with a secure bonding method as well as internal glazing beads, preventing removal of the panel or glass from the outside.
Thermal performance is excellent, exceeding current Building Regulations and providing U-Values as low as 1.2 w/(m2k).
Weather performance is also outstanding thanks to every door having multiple rubber weather seals. All Dutemann doors come designed with full weather protection as standard.
