Glass Information

What type of glass do we use in our windows?

It may surprise you to learn that up to 25% of the heat in your home can be lost through your windows. Without energy-efficient glazing, you are effectively throwing your money out of the window.

Did you know that by installing low-e windows, you can significantly improve your heat retention and reduce the amount of energy lost through your windows by up to 75%! Considering these figures and the cost of fuel today, it is easy to see why more and more people are opting to replace their windows and doors and saving money by incorporating low-e glass onto their new window frames. We can also re-glaze your existing windows with low-e glass, just give us a call for a costing. See below to get information on the glass we use.

Pilkington Low E Glass

Pilkington K Glass S is the latest high performance, low-emission soft coated product on the market which offers excellent thermal insulation when incorporated within an Insulating Glass Unit. (IGU).

It has a highly neutral appearance with optimal solar heat gain, thermal insulation and light transmission to provide the highest Window Energy Rating (WER) performance.

Pilkington K Glass S is a single stock, soft coated glass which can be used in annealed form or toughened, resulting in a product with the same thermal performance and neutral appearance. Once fabricated into a IGU, it can be used in windows in all types of glazing applications in new houses, conservatories and in replacement windows for existing homes.

Warm Edge Spacer Bar

As an added bonus we also use WARM EDGE SPACER BAR as standard if required, no extra charge.


Up to 80% of energy loss through a window occurs at it edge.

Warm edge products aim to minimize this energy loss. Warm edge technology refers to the edge construction of a double glazed unit that conducts less heat or cold than traditional windows and standard construction double glazed units. Standard double glazed units are constructed with an aluminium spacer to hold the glass apart. However, aluminium is highly conductive and also has an exceptionally high thermal energy loss.

Comparatively, double glazed windows fitted with warm edge spacer have a warmer internal edge temperature by up to 65% which helps to improve the thermal efficiency of the window and reduce the risk of condensation.


Warm edge also significantly lowers the temperature differential between centre and edge of the unit and up to 94% reduced heat loss at the external edge of the window.

While making a real contribution to the environment, this heat loss saving can help to reduce the heat consumption of a home which lowers carbon emissions and saves money on fuel bills.

Warm edge technology can also help to reduce condensation on your sealed unit by up to 70%. This reduction in moisture virtually eliminates the chance of mold growth and potentially harmful bacteria. This is an essential consideration for the increasing number of people who suffer from respiratory conditions such as asthma.






6.8 Clear Acoustic (Stadip) Silence Glass

6.8mm Clear Acoustic (Stadip Silence) Specially developed acoustic glass comprises of a PolyVinyl Butyral (PVB) interlayer which acts as a dampening core to prevent sound frequencies from vibrating from one pane of glass to the other. This absorbs and weakens sound energy, helping to act as a barrier to noise.  This plastic interlayer also has the additional safety and security properties of laminated glass. This thickness is considered a Class A safety glass (1B1). Stadip Silence acoustic glass offers optimum sound reduction performance approx 51 dB to 53 dB is possible, It also has a slightly better performance with higher frequency sounds.
