Triple Glazed UPVC Windows

Triple glazed upvc windows are becoming increasingly popular due to their ability to significantly improve the energy efficiency and sound insulation of the property. They can help to reduce outside noise, making the property a more peaceful and comfortable place to live. Our Liniar windows with triple glazing also improves security and retains warmth achieving an extremely low U Value of 0.9, making them a worth while and wise investment for any property.

The Benefits of Triple Glazing

Triple glazed upvc windows are a more energy efficient type of window than traditional double glazed windows. They have three panes of glass with a total glass unit thickness of 38mm instead of two and each pane is separated by a pocket of argon gas and a black warm edge spacer. Argon is a gas with low conductivity, which means it does not transfer heat very well. Triple glazing helps to keep the heat in the property during the winter and out in the summer. They also reduce condensation and lower the risk of mould.

Reduced Heat Loss

One of the primary benefits of made to measure upvc triple glazed windows is that they can help to reduce the amount of heat that is lost from your home. This is particularly beneficial during the winter months, when temperatures can drop below freezing. Because the windows are so well insulated, less heat will escape through the windows, which means your home will stay warmer and you won’t have to rely as heavily on your heating system.

But how do triple glazed upvc windows achieve this? The answer lies in their construction. Unlike traditional double glazed windows, triple glazing has three layers of glass, separated by argon gas-filled pockets. This extra layer of glass and insulation helps to prevent heat from escaping, making your home more comfortable and energy-efficient.

U Value & Lower Energy Bills

A specifically designed 'flatter' glazing bead accommodates a thicker 38mm triple glazed unit which can achieve U Values as low as 0.9 and a BFRC rating of A++. By reducing the amount of heat loss in your home, triple glazing in upvc windows can also help to lower your energy bills and lower the U Value achievable. When your home is well insulated, you won’t need to use as much energy to keep it warm, which means you’ll save money over time. In fact, studies have shown that homeowners who install triple glazed windows can save up to 30% on their energy bills annually.

Not only will you save money on your energy bills, but you’ll also be doing your part to reduce your carbon footprint. By using less energy to heat your home, you’ll be contributing to a more sustainable future for our planet.

Triple Glazing Noise Reduction

In addition to providing enhanced comfort, triple glazed upvc windows can also reduce outside noise. A secondary unit cavity makes sound wave transfer more difficult, providing superior noise reduction. This is particularly beneficial if you live in a noisy area, near a busy street or airport. The extra pane of glass helps to block out noise, which means you can enjoy a quieter living environment.

Find answers here to the most asked questions.

Choosing the right windows for your home is a major decision that balances comfort, aesthetics, and long-term savings. As energy costs rise and the push for sustainable living grows, triple glazed windows have moved from a ‘niche luxury’ to a mainstream solution, for homeowners looking to future-proof their property.

Triple glazed windows use three panes of glass instead of two. This creates two insulating gaps between the panes (usually gas-filled), whereas double glazing has one. The additional pane and extra cavity help improve insulation, comfort and overall window performance.

Yes. Triple glazing is designed to deliver higher thermal efficiency than standard double glazing, thanks to the extra pane and additional insulated cavity.

Triple glazed windows can achieve extremely low U-values (for example, around 0.9 depending on the specification), which helps reduce heat loss and keep your home warmer in winter and cooler in summer.

Example glass specification: 4/14/4/12/4 Soft Coat Low Iron with Black Warm Edge Spacer and argon-filled cavities.

Yes. Triple glazing can be very effective at reducing noise because it creates multiple physical barriers that disrupt sound waves.

If you live near a busy road or an airport, triple glazing can typically reduce external noise by around 35–45dB (depending on the glass specification and installation), compared with roughly 30–35dB for standard double glazing.

Triple glazing can significantly reduce internal condensation because the inner pane stays much closer to the temperature of the room. As a result, moisture in the air is less likely to condense on the inside of the glass.

You may occasionally notice external condensation on cold mornings. This is usually a positive sign that the windows are insulating well, keeping more heat inside your home.

Triple glazing is inherently more secure because it takes longer and creates more noise to break through three panes of glass than two.

When combined with modern frames and multi-point locking systems, triple glazing can provide an exceptional level of home security.

Yes. Triple glazing is excellent at reducing heat loss and can help eliminate “cold spots” near windows. The inner pane stays closer to the room’s ambient temperature, helping prevent that chilly feeling you can sometimes get with double glazing on winter nights.

For many homeowners, yes. Triple glazing can improve insulation and comfort, and may reduce heating demand — especially in colder areas or exposed properties.

The payback isn’t just about money. Triple glazing also delivers a warmer, quieter home with fewer cold spots and less condensation.

It can. Upgrading from older glazing to high-performance triple glazing may improve your home’s EPC rating, which can increase buyer appeal and potentially add value — particularly in colder regions of the UK.
