There is an increasing demand for 'glass garage doors', and now it is possible to have either real glass or the more traditional acrylic panes as used for many years.
What are the possibilities?
If you search on the internet today for a glass garage door you will probably see mostly the same images - a generic sectional type garage door manufactured from aluminium sections with varying sizes of glazing inserts. These will be polycarbonate, or maybe glass if the manufacturer is in a country where it is possible to place glass above people's heads within the construction laws. Most of the images you will see on the internet at present will be American sectional type doors. Here in the UK of course, and in most of Europe, you can have a toughened acrylic in twin or triple sheet construction to create a 'glass garage door' effect. The use of glass in any doors is subject to some stringent regulations in this country, and therefore in a large garage door to use the kind of specification of glass as required would be far too heavy and onerous in daily use.
Glass Garage Door Options in the UK
In the UK right now there are two ways to get what could be described as a glass garage door - One is to use commercial sectional door systems and have one of the various glazing section options (ALRF42 and the Vitraplan door from Hormann as one example) and the other is to have the Silvelox Securlap trackless sectional door and have the panels in mainly glazing sections with a border framework.
