A traditional design doesn’t mean compromising on security. Entrance doors from Sieger are all created with security at their core. The Grosvenor Entrance Door has a fully integrated locking system built within its core. The locking system has a 10-point securing mechanism that is operated via laser cut keys, the latest technology in building security.
Each Grosvenor door design has been styled in keeping with the UK’s elegant home designs. The door leaves feature clean linear and geometric shapes with sophisticated elements of glazing integrated into the door pane for light and visibility. To complete the traditional appearance a variety of handles, knockers and letter boxes are available to complete this style.
In addition to various door styles you also have the choice of over 30 metallic finishes and colours for even greater design flexibility.
