Silvelox Overlap BOX

Product Finishes: , ,

Bold Georgian style panels make Silvelox Overlap BOX the perfect choice for a period property.

Silvelox have created a totally new kind of garage door with the Overlap range. Overlap is a trackless sectional garage door. Unlike other sectional doors, the Overlap has only two sections rather than four or more. It opens without the need for ceiling tracks leaving your roof space clean and clear. Another big difference from most garage doors is that Overlap doors have no springs. The door uses a weight balance system. This makes for a smoother more even operation. The BOX also uses the high tech Silmotion operator which is neatly hidden away within the head rail of the door.


With your new Silvelox Overlap BOX you will have the beauty of timber but without the problems. The BOX is made from okoume hardwood engineered board that is built around a ridged box section chassis.  You will have no worries about splitting and warping that often comes with solid timber. The frame and lifting gear of the door are made from 2mm thick galvanised steel finished in anthracite for a tough and durable wipe clean finish.

Timbers and finishes for Silvelox Overlap BOX

Firstly, the BOX comes as standard in okoume hardwood which is fully finished to your choice of a selection of paint finishes and stains. Secondly other timbers that are available are oak, larch, Northern spruce and teak. Also, if you wish to match in your new garage door to an existing colour scheme, it is possible. Have the Silvelox Overlap BOX finished to any standard RAL colour or provide a sample to use the colour matching service available.


Silvelox Overlap are currently the best insulating garage doors available. Prior to this range, traditional sectional doors were the best insulators. Overlap doors are approximately one third more energy efficient than other sectional garage doors.
