Twinfix have introduced a new roof glazing panel system that can be used to replace individual panes or entire runs of failed and cracked glazing with multiwall polycarbonate, whilst retaining the existing glazing bars.  You simply take off the existing capping bar, replace the glass with an Adaptaglaze panel and mechanically re-fix the capping bar

Effective roof glazing refurbishment can then work as part of an ongoing maintenance programme, rather than a single, sometimes prohibitive, capital cost.  If the existing glass glazing bars are in good condition, the choice can be made between replacing a whole run of glass, or simply replacing a damaged pane as and when necessary

Each lightweight panel consists of an aluminium frame that is fitted with multiwall polycarbonate.  Multiwall polycarbonate is impact resistant and, once installed, avoids the need for an ongoing maintenance programme, which is often required with glass.  It also eliminates the high costs and potential dangers caused by broken glass falling into the premises below; particularly vital in food processing areas, schools, leisure centres and railway stations.

Because polycarbonate is self-extinguishing, it has excellent fire resistant properties.  No burning drops are produced and the polycarbonate makes no contribution to the growth of a fire through flame spread.  With a fire classification of 1y to BS476, (part 7), it is the preferred glazing material.

With its honeycomb structure and smooth surface, multiwall polycarbonate offers superior heat insulation and superb light transmission, both of which properties can help to save considerably on energy costs.
