Silvelox Overlap EMI

Product Finishes: , , ,

Silvelox Overlap EMI is the door which looks like a traditional sectional garage doors but with the performance you would expect from a Silvelox.

Although EMI might look like other sectional garage doors, it is in fact a trackless sectional door. Rather than being in 4 sections, it is in two. On the inside, where you would expect to see ceiling tracks, springs and a boom operator, you see instead a clean, clear ceiling space. All of the lifting gear on the Silvelox Overlap EMI is built into the frame. The leaves of the door give a much more aesthetically pleasing space inside the garage.


EMI sections are made from okoume hardwood engineered board  built around a steel box section chassis. This allows these doors to be made in large sizes up to 5500mm wide. The benefit of using an engineered board rather than solid timber is that it gives you the beauty of natural wood but with no shrinking or warping prevalent with solid boards.

Colours and Finishes for Silvelox Overlap EMI

Want to get away from an outside timber surface altogether? No problem. EMI is one of 3 doors in the Overlap range that can have the external face of the door finished in steel. This can then be lacquered to any of the standard colour finishes. Optional RAL finishes, or foil finished with a pvc embossed wood effect are other choices. If you love the natural beauty of timber then as well as okoume there are other options. Northern spruce, oak, larch and teak are also available.


As energy costs rise and we all become more environmentally conscious, retaining heat becomes a more and more important factor. Your new Silvelox Overlap EMI is one of the most energy efficient garage doors available. It is approximately one third more energy efficient than a traditional sectional garage door.

If you’d like to see and try a Silvelox Overlap garage door we have one on display at our garage door showroom in Lancashire.
