What is the difference between double and triple glazing

Low-E glass has an invisible coating that dramatically reduces heat transfer and reflects interior heat into the room. You might notice that Low-E glass looks a little darker than regular glass, but the tint effect is minor and only noticeable if you have Low-E and non-Low-E glass next to each other or view light-coloured net curtains through the glass.

High-quality double glazing with a Low-E coating should be more than sufficient for most situations. However, triple glazing can be a good choice if you want maximum thermal insulation, such as for an ultra-low-energy modern new-build house. The higher the rating ranging from 20 to 65 , the better the acoustic insulation.

Whether you should opt for a higher or lower STC rating depends on your situation, e. You can compare the amount of light that windows let in by looking for their Light Transmittance value LT. An LT of 0. The LT value of a triple-glazed window is usually slightly lower than a double-glazed window e.

The LT value is also affected by the thickness of the glass coating. For example, one pane of laminated glass may have a lower LT value than three panes of glass designed with very high light transmission.

The amount of light your windows allow in is a matter of personal taste. One of the benefits of Low-E glass, which we use in our double- and triple-glazed windows, is that it minimises the amount of heat energy that passes through the glass while maximising natural light transmission. Triple glazing has additional glass and one more air chamber than double glazing.

This keeps the inner pane temperature higher than double glazed windows. This also reduces the chance of a gas chamber leaking, which may cause condensation within the panes. Both triple and double glazing windows in Somerset are safer than single pane windows. However, the additional pane in triple glazing makes the windows a lot harder to break and reduces the chance of invasion.

The energy savings from switching from single to double glazing are considerable, but the difference between a U value of say 1. The key benefits are really to do with comfort. If you insulate the walls, roof and floor of a house, and you ignore the glazing, you end up with cold spots surrounding the windows at night, which cause draughts, draw heat away from you if you sit next to them, and result in streams of condensation running down the panes. So, in essence, the standard of glazing has to match the standard of the insulation elsewhere in the house, so that the warm wrapping around the house performs consistently.

Windows behave rather differently to walls and roofs in that, when the sun is shining, they are capable of absorbing heat. In fact, the very best double glazed windows are already capable of being net heat contributors over the course of a heating season. In contrast, triple glazed windows slightly reduce the heat absorption characteristics of a window.

To reflect these complexities, the British Fenestration Rating Council has devised a scheme for the energy labelling of windows, from A down to G. The top rating is reserved for windows that are reckoned to absorb as much heat as they lose, and they include both double and triple glazed windows. Bit by bit, we are being encouraged to switch from double to triple glazing.

You may not have noticed yet but the pressure is on to improve the energy performance of windows and we are now reaching the stage where mere double glazing will no longer be enough.

Worked non stop all day to make sure that everything was finished to perfection. A credit to your company. Can you please pass on my thanks to them. Once again John, thank you for your help. It was much appreciated. Great service and quality workmanship from the Senator Cavan team.

This team have helped to transform my older house for renovation into a home. A great range of colours to choose from with helpful advice and guidance from Michael, and a great gang of hard working installers.

Quality re-plastering and making good, and also cleaning up and the removal of all waste — highly recommended and reliable Company. With the Government announcing further level 5 restrictions to halt the spread of COVID and for the safety of all our staff, suppliers and customers, our factory and showrooms will temporarily close from Friday 8th January until further notice.

There will be no installations of windows and doors over this time. Our team have the capability to work from home and we are still here for you to answer any queries you may have. Once we are in a position to re-open, we will work swiftly to schedule new installation dates for customers awaiting our products.

Be assured, we are monitoring the situation closely and will continue to follow official advice. You can contact us remotely, over the phone or by email for any pricing requests and queries that you may have.
