Triple Glazed Units

Triple glazed units are a premium glazing solution for UK homes and commercial properties, offering enhanced thermal performance, noise reduction, and energy efficiency. By incorporating three panes of glass with two insulated cavities, triple glazing delivers superior comfort and long-term value.

What Are Triple Glazed Units?

Triple glazed units consist of three panes of glass separated by two sealed air or inert gas cavities, typically filled with argon or krypton. This additional layer of insulation significantly reduces heat loss and improves soundproofing compared to double glazing.

Triple glazed units are commonly used in new builds, energy-efficient homes, and areas requiring superior noise reduction or thermal performance.

Key Benefits

Exceptional Thermal Efficiency

Triple glazed units provide one of the best insulation performances, helping retain heat during winter and maintain cooler indoor temperatures in summer.

Enhanced Sound Insulation

The additional glass layer and insulated cavities reduce external noise, making triple glazing ideal for busy streets or commercial locations.

Improved Security

Triple glazing is harder to break than single or double glazed units, and can be combined with laminated or toughened glass for enhanced protection.

Reduced Condensation

The advanced thermal performance lowers the risk of internal condensation, protecting frames and surrounding surfaces.

Energy Cost Savings

By improving insulation, triple glazing reduces heating costs and contributes to lower energy consumption.

Increased Property Value

Modern triple glazed units improve energy ratings and overall market appeal, making them a strong investment for homeowners.

Types of Triple Glazed Units

Standard Triple Glazing
Three panes of float glass separated by argon-filled cavities, suitable for most residential windows and doors.

Energy-Efficient Triple Glazing
Incorporates low-emissivity (Low-E) coatings and argon/krypton gas for enhanced thermal performance.

Acoustic Triple Glazing
Uses varying glass thicknesses to maximise sound reduction for urban or high-noise areas.

Safety & Security Triple Glazing
Features toughened or laminated glass to meet safety or security requirements.

Glass Options

Triple glazed units can be customised with a variety of glass types, including:

Clear float glass
Low-E energy-efficient coatings
Toughened safety glass
Laminated security glass
Obscure or patterned glass for privacy
Solar control glass

This flexibility allows triple glazed units to meet both functional and aesthetic needs.

Spacer Bars & Warm Edge Technology

Modern triple glazed units use warm edge spacer bars to reduce heat loss at the edges and minimise condensation. Spacers are available in various colours to match window frames and enhance the overall appearance.

Triple Glazed Units and UK Building Regulations

Triple glazing installed in the UK must comply with building regulations regarding thermal efficiency and safety. Units must meet or exceed U-value requirements and use safety glass where required. Professional installation ensures compliance, performance, and certification.

Fitted Start of may-23. Required a full house change for new double glazing, secondary glazing, 2 back doors and a composite front door arch. Digital windows ltd were amazing from start to finish. They came within 2 weeks to view the property for measurements and give advice on what we can/cannot do. I asked them lots of questions and they were happy to answer. The customer service is excellent. They were clear in the lead time and therefore I had booked them in advance. They put down protection and covering throughout and ensure the place is left tidy. They took good care in ensuring no unnecessary damage was done in the way they took care for taking out the old windows. They mitre cut properly whats needed in regards to trim and take attention to detail for the final quality and finish. They ensured the inside and outside had high quality finish. Going the extra mile in the mortar/cement finish to make it look better. The team are respectful and clearly have great experience and attention to detail for a high quality finish. I am a customer who hawk eyes all the works and notices the smallest of things (like a bubble in silicone), however this company gave me peace of mind. I would 100% go back and recommend to all to go here for windows and doors. Amazing company, great quality finish and great customer service. Great work by Hatim, Mustafa and the team, Thank you!

We were recommended to Digital Windows and overall we were very pleased to have chosen them. They gave us a prompt, competitive quote for Aluminium windows which took about 7 weeks from paying the deposit to installation. The fitters were very professional and the job was done to a very high standard and I would definitely use them again.

Very pleased with the product and level of service of the fitters from Digital Windows. The fitters came prepared with dust sheets and cleaned up everything before they left for the day.
Would definitely recommend this company. .

I ordered my double glazing for the whole house in late October and was told that will be ready to fit in 6-8 weeks and we had a call early December that they will start work and within 5 days work was completed and all rubbish cleared and no bother from the workers at all and also obliged to do bits xtra for us too.Definitely recommended the company as they have been established for many years

Highly impressed with this professional company. From a prompt and skilled initial survey to the high quality finish. The door is of superior quality and the workmanship and installation process was excellent. As a customer, I was kept updated and asked all my preferences. It has now been in place for a few months and looks like it will last for many decades. Thank-you very much to the whole team!

Digital Windows have just fitted some black metal bifolding doors in my flat, with a catflap in one of the panels. I am delighted with the results, my doors have transformed my flat and they look stunning. They were so quick to install, and dispose of the old ones. The work is immaculate, and they were tidy too. I highly recommend this company .
