Double vs Tripple Glazing

When shopping for new windows and doors, many people face the challenge of choosing between double or triple glazing. If you’re not well-versed in window technology, it can be hard to understand the differences or whether an extra pane of glass truly offers significant advantages.

The double-glazed windows and doors deliver exceptional performance, with a U-value of 1.2W/m²K and a sound reduction of 37dB as standard, along with a centre pane U-value of 1.0W/m²K. Current building regulations require a minimum U-value of 1.6W/m²K, which means our double glazing exceeds performance expectations.

However, you might still be considering triple glazing. One reason for choosing triple glazing could be the overall SAP (Standard Assessment Procedure) calculations on a new build or when extending a property, as certain energy efficiency standards must be met. UGS Ltd. is committed to meeting these requirements with the most cost-effective solutions. Rather than offering a higher-performing triple-glazed unit with a U-value of 0.9W/m²K at a premium cost, we focus on long-term customer benefits. In many cases, the extra investment in such an upgrade might be better allocated to other aspects of the build.

* Energy Rating show overall energy efficiency of the product. The entire window (the frame and the glass) is assessed to allow for heat loss, draughts and solar gain, giving a rating that indicates the overall impact of fitting that window in your home. *The R Value Measures resistance to heat gain or loss. Example, a typical insulated wall has an R-value anywhere from 12 to 19.

* The U Value of the glass tells us heat loss through the glass, the glass edge and the frame.

* The G Value of the glass tells us how well the glass transmits heat from the sun.

What are the Advantages of Upgrading to Triple Glazing?

Upgrading to triple glazing can offer benefits when applied appropriately. For example, in a thermally efficient building, a triple-glazed unit combined with a thermally broken frame can achieve a U-value as low as 0.7W/m²K. Additionally, sound insulation can be improved, reaching around 41dB.

UGS Ltd is a leading provider of premium window and door solutions across the UK, offering top-quality products at competitive prices. With accurate information, customers can make informed decisions—our standard range already provides excellent value, superior thermal efficiency, and an impressive lifespan of up to 60 years.

What Are Argon-Filled Windows?

In double-glazed windows, the space between the two panes can either be filled with regular air or injected with a gas. While air-filled windows tend to be the more affordable choice and offer some degree of energy efficiency and noise reduction, argon-filled windows are a more worthwhile investment when it comes to long-term performance and energy savings.

Argon is an inert, nonreactive gas, which helps to ensure the windows maintain their effectiveness over time. Unlike oxygen in the air, which can lead to rust and corrosion in metal components, argon prevents such deterioration, ensuring that the windows remain efficient for a longer period.

Additionally, argon is more viscous than air, meaning that molecular movement is slowed down, reducing both heat transfer and heat loss. Argon’s density also makes it heavier than air, which helps to reduce the likelihood of condensation forming between the panes.

These characteristics make argon an ideal choice for high-quality double glazing. Homeowners should opt for argon-filled windows whenever possible, as they offer better insulation, leading to improved heat retention and potentially lowering energy costs. Moreover, argon-filled windows tend to have a longer lifespan, making them a more valuable investment over time.

If you’re thinking about replacing or installing new double-glazed windows in your home, it’s worth taking the time to explore your options and select high-quality products that will stand the test of time. Choosing argon-filled units can enhance the comfort of your home, add value, and lead to greater satisfaction with your property.

Secondary Glazing Solutions for Grade I & II Listed Buildings

Preserving the character and heritage of Grade I and Grade II listed buildings is essential, but this often comes with challenges when it comes to modern comforts. Traditional windows in these buildings cannot be replaced, only restored, leaving homeowners with limited options to improve insulation, reduce noise, and enhance security. That’s where secondary glazing comes in—an ideal solution for listed properties. Find out more about the Range of Secondary Glazing Units.
