Triple Glazed Windows

What are Triple Glazing Windows?

Triple Glazing Windows are energy-efficient windows made with three panes of glass, held together in a glazing unit, with each pane of glass separated by air or inert gas. The addition of a third pane slows down the thermal transfer of heat or cold, meaning triple glazed units provide superior insulation over single glazed windows or double glazed windows, as well as better noise reduction and increased security. Windows & Doors UK triple glazed windows are among the highest performing glazed windows on the market, with low U values and enhanced thermal performance across the entire triple glazed unit. We also only use responsibly sourced and FSC® certified hardwood and timber to manufacture our window and door frames in our dedicated UK joinery. With hand crafted corner welds, weather proof window gaskets, multi point locking systems, and noise reducing trickle vents as standard, Windows & Doors UK triple glazed windows are available in a variety of designs and styles including our popular timber casement windows, sash windows, awning windows, and bay windows.

Why is triple glazing better than double glazing?

Are new triple glazed windows worth the money? A resounding yes. In the battle of windows, triple glazing emerges as the undisputed champion, outshining its double-glazed counterpart in every aspect:

Energy efficiency

Triple glazing wields an impenetrable shield of insulation, effectively repelling heat loss in winter and maintaining your home’s coolness in summer. Its U-value (typically 0.73 W/m²K), a testament to triple glazing insulating prowess, is 50% lower than a double-glazed window, meaning it reduces heat loss by up to 50% more, compared to double glazing.

Soundproofing

Installing triple glazing is not just about saving energy, but reducing noise pollution too. The extra pane of glass acts as an acoustic blanket, muffling the outside world, whether that’s relentless traffic hum or a noisy neighbourhood. Soundproof serenity awaits with triple-glazed sealed units.

Security

Triple glazing doesn’t just guard against energy loss and sound intrusion; when you install triple glazing, you’re increasing your home’s security from physical intruders. With its reinforced structure and three glass panes, when you choose triple glazing, you’re choosing to add an extra layer of protection to your home.

Cost savings

While triple glazing may command a higher upfront cost, its long-term benefits far outweigh the initial investment. The savings on energy bills alone make them a worthwhile investment, but then there’s the enhanced comfort and security which will truly make your home a haven of tranquility.

Frequently Asked Questions

In a word, yes. Triple glazed windows are worth it.

These thermally efficient windows insulate better than even new double glazed windows. They keep your house warmer in the winter and cooler in the summer. They have enhanced noise cancelling properties, and because of the additional pane of glass, they provide additional security to your home. While they’re more expensive upfront than single glazed windows or double glazing, they help lower energy bills in the long run, and keep your home warmer and more comfortable.

Yes. Triple glazed windows can reduce noise ingressing and egressing your home. By having an additional pane of glass, you’re literally putting an additional barrier up to prevent unwanted soundwaves from polluting your home. In fact, research suggests triple glazed windows can reduce up to 20% more noise than double glazed windows. However, if you want truly soundproof windows, you could consider acoustic glazing, specialised glass that’s been bonded together to absorb and dampen sound waves, deadening noise transfer altogether. Read more about how to soundproof windows for noise reduction.
