Silvelox Overlap GEO

Product Finishes: , ,

Silvelox Overlap GEO is a luxury hardwood garage door. The contemporary cross hatch grooves make it one of our most popular models.

Overlap is the world’s first trackless sectional garage door. Unlike traditional sectional garage doors overlap has only 2 sections. It is counter balanced with weights rather than springs. This gives the door a low maintenance, extremely long lasting, lifting mechanism. Silvelox Overlap GEO requires no ceiling tracks whatsoever. Even when automated, the operator is concealed within the head rail leaving a clear space within the garage. This makes it one of the neatest garage doors available.


Multi-ecowood engineered panels, made from okoume hardwood, are built onto a ridged steel box section chassis. This creates the door sections. The GEO pattern is then cut into the face of the panels with a CNC router. The door frame is made from galvanised steel, powder paint coated and, if necessary, clad with timber.

Security and Insulation

These two things with Overlap are key. Silvelox Overlap GEO sections are 75mm thick. Almost twice the thickness of traditional sectional doors. This gives the Silvelox Overlap GEO thermal insulation values as low as U=1.0W/m2k. To cut or break through these thick and robust sections would require specialist equipment. In the case of forced entry, Overlap doors have two mechanical security devices; Silblock and Silhook. Silblock is two spring loaded shoot bolts which engage between the sections to prevent them being forced apart. Silhook are two mechanical locking latches which are operated by the motor. Manually in the event of a power failure.

Woods and Finishes for Silvelox Overlap GEO

GEO is available in a range woods, including oak, veneered onto the okoume panels. The range of standard finishes, which you can see above, include popular RAL colours and stain finishes. It is also possible to have the door painted to any RAL colour or to have a colour or stain matched from your sample.

Bespoke sizing – unlike many garage doors Overlap doors do not work on standard sizing. The door will be purpose made to fit your garage.
