- C E Marking
- Planitherm TOTAL Glass (Low E)
- Warm edge spacer
- Argon or Krypton Gas filled
- Primary Seal (dual seal units)
- Double or Triple glazing
- Toughened/laminated glass

- Decorative glass,
- Quadra bar, georgain bar, duplex bar
- Heritage units
If you are considering replacement or new windows, there are a number of rules, old and new, which need to be complied with. Below is an outline of the latest legislation, but for more information please speak to one of our experts. These laws will mean that care needs to be given when selecting double glazing window for a new construction – or for replacement windows – as it will affect any eventual sale of the home.
CE Marking and harmonised European Norms for quality compliance;
All products manufactured in Europe, including double glazing window, must now comply with the harmonised European Norms (hENs), to ensure European wide technical standards are met. Double glazing window marked with the CE logo are hEN compliant and it is important to check this before purchasing replacement windows. hENs apply to basic float glass, coated glass, toughened glass, laminated glass and energy efficient glass. Modern Glass is proud to meet with these high standards and be able to manufacture and supply CE marked units.
Window Energy Ratings
Many houses are unable to achieve even a D rating on the Home Information Pack scale. For a home to achieve a C or above rating in the Energy Performance Certificate, the type of double glazing and window chosen is crucial and standard double glazing window will not be sufficient.
Heating accounts for 60% of energy used in the home. Double glazing window plays a key role in a home’s overall energy rating as up to 25% of heating used can be lost through a double glazing window. As such, windows have their own labelling system – under the British Fenestration Rating Council’s Window Energy Rating scheme. As with the EPC, Window Energy Ratings are also measured on an A to G scale.
The thermal insulation properties of Low E double glazing window achieves by far the greatest Window Energy Ratings and, depending on their construction, can obtain an A, B or C grade on the WER scale. To illustrate the difference, 1m2 of Low E glass emits 91 kilos less of carbon dioxide per year than 1m2 of standard double glazing window.
The most well known Low E double glazing windows are Planitherm TOTAL by Saint Gobain whichbwe use at Modern Glass. Further energy savings can be made by using warm edge ‘thermal break’ spacer bars. These warm edge spacer bars can reduce heat lost around the edge of the window by up to 65%.
As well as complying with legislation, the savings on heating that can be made by improving a home’s window energy ratings are substantial. By selecting the most energy efficient Low E windows (an A on the energy rating WER scale), a typical semi-detached home will reduce its heating bills by an estimated £9000 over 20 years compared with a standard double glazing window.
