Triple-glazed window fitting for a more comfortable and energy-efficient home

In short, yes. Triple glazing uses the same technology as double glazing, but more effectively, by adding an extra layer of glass and gas. The additional layer in triple glazing results in superior thermal efficiency, sound insulation and condensation control, among other things. 

U-value, a measure of heat loss through glass, clearly demonstrates the improved efficiency of triple glazing. The lower the U-value, the better. Double-glazed glass typically has a U-value around 1.2, while triple glazing achieves an impressive 0.8. This means that triple glazing reduces heat loss and gain by 33%. With triple glazing installed, your home will be warmer in the winter, and stay cooler in the summer. 

While requiring more materials (and thus a higher cost), triple glazing’s long-term energy savings make it a very worthwhile investment, especially for homes in the UK.

Yes, triple-glazed windows generally cost more than their double-glazed counterparts. You can typically expect a 30% to 50% price difference. This is due to the fact that triple glazing requires more materials to manufacture, and due to its increased weight, needs to be encased in a more robust frame, also resulting in an increase of materials required. However, this additional investment often proves worthwhile due to the significant long-term benefits that triple-glazing offers.

The superior insulation of triple-glazed windows prevents heat loss in winter and reduces heat gain in summer, resulting in significantly lower heating and cooling bills over time. This energy efficiency can help offset the higher initial cost.

Triple-glazed windows typically boast an average lifespan of 20 to 25 years, although many surpass this duration. With proper care and maintenance, such as regular cleaning of frames and glass, and careful inspection for signs of wear and tear, the longevity of triple glazing can be extended. Taking these proactive measures not only ensures optimal performance but also contributes to energy efficiency.

The growing focus on energy efficiency in UK housing means homes with high EPC (Energy Performance Certificate) ratings are becoming increasingly desirable. All buildings receive a rating between A (most efficient) and G (least efficient) and an EPC certificate is mandatory when selling or renting properties. New legislation may soon require rental properties to achieve a minimum C rating, further emphasising the importance of energy efficiency improvements.

Consequently, triple-glazed windows can significantly increase your property’s value. Their superior insulation boosts your home’s EPC rating, making it a more attractive prospect for buyers seeking lower energy bills and increased comfort. As energy efficiency becomes more important, homes with A, B, or C ratings will likely fetch higher prices on the market.

Triple-glazed windows may also further increase the perceived value of your property as are considered a premium upgrade. Their presence signals to potential buyers that your home has been built or maintained with high-quality materials and attention to detail.
