The ultimate comparison between double and triple glazing for windows and doors

Windows and doors are an essential part of any building, offering both functionality and aesthetic appeal. But with rapid advancements in technology, the choices for window and door glazing have expanded, making it challenging to determine which option is the best fit for your property. In this article, we will compare double and triple glazing for windows and doors, looking at energy efficiency, noise reduction, security, cost, and aesthetics, to help you make an informed decision.


Energy efficiency

Energy efficiency has become a top priority in the building industry, with concerns over rising energy costs and the environmental impact of excessive energy consumption. According to research by the Department of Energy and Climate Change, heat loss through windows and doors accounts for 10%-25% of total heat loss in a building. Double glazing offers two layers of glass with a gap in between, providing a barrier to heat transfer. On the other hand, triple glazing offers an additional layer, making it more effective in reducing heat loss. A study by the Building Research Establishment (BRE) found that triple glazing can save up to 2-3% more energy than double glazing, making it a better option for energy-conscious homeowners.

Noise reduction

Noise pollution is a common problem in urban areas, leading to higher stress levels and reduced quality of life. Double glazing can significantly reduce external noise, thanks to the two layers of glass that absorb the sound. However, triple glazing, with an additional layer of glass, provides an even greater level of noise reduction. A study by the University of Salford showed that triple glazing can reduce noise levels by up to 35 decibels, compared to 30 decibels for double glazing. This makes it a popular choice for properties located in busy streets or near airports and train lines.



The safety and security of a property are crucial factors to consider when choosing windows and doors. Double glazing offers two layers of glass, making it more difficult for burglars to break in. However, triple glazing with an extra layer of glass provides an added level of security, making it harder to break into. Additionally, triple glazing also comes with stronger frames and locks, further enhancing the security of a property.



One of the most significant considerations when choosing between double and triple glazing is the cost. Triple glazing, with an additional layer of glass and more complex installation, is pricier than double glazing. However, in the long run, the energy savings from triple glazing can outweigh the initial cost. According to the Energy Saving Trust, homeowners can save up to £160 per year on energy bills by switching to triple glazing.

Finally, the appearance of windows and doors can greatly impact the overall look of a building. Both double and triple glazing offer a sleek and modern aesthetic, elevating the appearance of any property. However, some people prefer the slimline look of double glazing, while others opt for the added layer and increased insulation of triple glazing.
