3. Safety Glass

Safety glass, also known as toughened glass, is a type of safety glass which is required by law for any window below 800mm or for windows fixed to the side of a door, as well as all door glass. Your glass should have a stamp in a corner which indicates it is safety glass.

4. Energy Saving Glass

Low-E coating, or low-emissivity coating, is a type of thin, invisible layer applied to glass surfaces to enhance their energy efficiency. The "E" in Low-E stands for "emissivity," which refers to a material's ability to radiate energy. All windows fitted after 2002 will have this.

5. Argon Gas

"Argon is an inert gas that has a lower thermal conductivity and helps with soundproofing, condensation reduction, and energy efficiency.
By improving thermal performance which means lower energy consumption for heating and cooling, which can reduce carbon emissions and save on energy bills.

6. Warm Edge Space Bar

A warm edge spacer bar is a component used in double glazing to improve the thermal efficiency of windows, reduce condensation and helps with environmental impact by improving thermal performance which means lower energy consumption for heating and cooling, which can reduce carbon emissions and save on energy bills.

The Calculated Prices

The glass calculator should be used as a guide only for the price and installation of a replacement double glazing unit in our service area. Discounts are offered for more than one replacement unit in the same window or property. Limitations apply to some installations where special access equipment is required or the window location is over a tiled roof or difficult to reach. Externally glazed windows are height restricted to a normal two-story property.

All replacement units will be surveyed by our engineer to ensure they meet or exceed building regulations for both glass safety and energy efficiency.
