Glazing Bars for Timber Rafters

​ThermGard-R aluminium glazing bars for timber rafters provide the ideal combination of the natural beauty and warmth of timber inside with a weather-tight, maintenance free external finish. The carrier rail features integral drainage channels to ensure in the unlikely event that water penetrates the capping and high-performance gaskets, it is safely transported to the outside of the building. A continuous screw on pressure plate with provides outstanding glass retention and a choice of decorative external covers are available to provide either contemporary glass roof appearance or a more traditional heritage style for roof lanterns on period buildings.See here for typical hardwood conservatory details [1] [2]).

“We’ve fitted ThermGard-R glazing bars time and again and like all Lonsdale products, we have never been let down” - John Robinson, Robinson Glazing Services
