If you are looking for permanent secondary glazing, or want to install it on the outside? In the table below you can see which mounting method suits your frame best. Using secondary glazing brings about many benefits, including acoustic insulation and thermal insulation as well as notable reductions in pollution and condensation. Our unique design mirrors the structure of your existing primary windows so that the secondary glazing is hardly visible once installed.
It has an impact resistance similar to that of normal glass, but in case of breakage, the mesh retains the pieces of glass. Tight sizeThe actual size of an opening into which glass is to be glazed and is measured from the rebate platform.

The coating has hydrophilic properties which mean it attracts water over its entire surface, avoiding unsightly uneven water marks. This is made from a sheet of annealed glass reheated beyond its annealing point of around 1200 degrees Fahrenheit and then cooled slowly. Heat strengthened glass may be twice as strong as annealed glass, but may still need to be laminated for use in buildings. Tempering is the process by which annealed glass is heated in the same way as heat strengthened glass. The glass is cooled more rapidly which allows the internal portion of the glass to remain fluid for longer than the outer surfaces. This means that an equal amount of tensile and compressive stresses are formed across the glass which allows it to become in the order of four times as strong as annealed glass.
