As of now, only a selected few would think of installing single glazing. Besides, Building Regulations do not allow it these days, apart from listed properties. However, is there going to come a moment when double glazing is also regarded as insufficient, and triple glazing becomes the new thing?
With some compelling discussions in triple glazing’s favour and the increasing demand for energy efficiency in most homeowners, how important is it to invest in this high-performance alternative?
1. How does double glazing differ from triple glazing, and what is the importance?
New builds usually consist of large swatches of glazing – roof lights, sliding doors, and picture windows. However, all that glass causes energy efficiency implications since heat moves through it a lot more readily than it would on an insulated wall.
Since there exist even more stringent Building Regulations, most glazing companies have decided to rise to the challenge of manufacturing better-performing products. Because of the enhanced insulation from containing two air pockets rather than one, triple glazing is a practical solution.
2. Security & noise benefits
Generally speaking, triple glazing can significantly improve security since it’s tough to break. Although there’s a minor advantage in terms of noise reduction, if the acoustics are your top priority, then there are other much more efficient options in this area. These might include secondary glazing or units containing a relatively larger air gap between laminated glass and the panes.
3. Added features
It is not just the three glass panes that make the unit more efficient. You can find other features (both in double- or triple-glazed products) that enhance performance. These may include an inert gas like argon kept between the glass; this is less conductive (and thus more insulating) than air.
Furthermore, low E glass could improve insulation — the product consists of invisible metal oxide on a single inward-facing pane; this reflects heat back into your room. Lastly, check out for products featuring “warm edge” spacer bars positioned between the panes. They’re made from plastic composite, and they conduct comparatively less heat than the aluminium conventionally applied for this component.
4. A low-energy home
Generally, triple glazing is standard when it comes to northern Europe’s colder climates. It is also regarded as an essential ingredient in present-day, ultra-low-energy new-build homes. They often use a combination of features to make them more efficient, including high insulation levels and removing every micro-gap within the fabric to allow airtightness.
Typically, triple glazing is accompanied by Building Regulations standards when it comes to energy efficiency; this is if the products have been installed properly. Undoubtedly, it makes no sense to own super-insulated windows when surrounded by gaps for the air to pass out.
You should expect to incur about 20% more for a like-for-like triple unit. However, incredibly high-spec, Passivhaus-standard windows could cost much more.
5. How important is it?
There are specific situations that make an affirmative “yes” to triple glazing more probable. If you stay in a cold climate, it would have a substantial difference to your overall comfort than if your house is in a milder area.
Enjoying optimum advantages from triple glazing entirely depends on energy efficiency elsewhere in your house. For this reason, it’s remarkably recommended in a new place where airtightness and insulation levels are also incredibly good.
In general, glass involves one of the most energy-intense production methods there is. Therefore, it is also about considering whether the additional pane is worth it for the extra comfort level it will provide, instead of thinking about it generally from the perspective of reducing your bills and saving the planet.
