Benefits of Triple-Glazed Windows

With U-values around 0.8 W/(m²K), Norrsken triple-glazed windows perform 40-50% better than typical double glazing - but typically cost only 10-15% more. 

But the real difference isn't in the numbers - it's in how your home feels. On cold days, the interior glass surface of our triple-glazed windows stays several degrees warmer than double glazed alternatives. This means no cold drafts, no condensation, and that wonderful feeling of cozy warmth even when winter rages outside.

"The experience of living in the house is, frankly, amazing. Our passive house maintains a temperature of 21 degrees during the winter...it's like having pictures hanging on the walls everywhere." 

A number of our triple-glazed windows are suitable for passive house development.

Superior Thermal Performance

Transform how your home feels, every day of the year. 

In most homes, up to a quarter of all heat is lost through windows and doors. Our triple glazing with U-values below 0.8 W/(m²K) delivers comfort you'll notice immediately - no drafts, no cold spots, no condensation. The result? A home that stays beautifully comfortable while reducing energy costs by up to 50% compared to standard double glazing.

Peaceful, Quiet Living 

Triple glazing reduces noise by physically blocking sounds. Most customers report noticeably quieter homes with triple glazing installed. 

Our triple-glazed units create a superior sound barrier that transforms busy homes into peaceful sanctuaries. Enhanced further with laminated glass options, our acoustic engineering dampens external noise to create the calm, comfortable environment where life's best moments happen.

Advanced Security

Protection that gives you complete peace of mind.

Every Norrsken window and door conforms to PAS 24:2016 enhanced security standards through multi-point locking systems and robust construction. Optional laminated glass upgrades provide additional protection, ensuring your home remains both beautiful and secure.

Condensation-Free Comfort

Clear views and healthy interiors, year-round.

Condensation occurs when warm, moist air comes into contact with a colder surface. Triple glazing maintains warmer interior glass surfaces that reduce condensation problems common with standard glazing. The advanced thermal barrier keeps interior glass temperatures comfortable, protecting your views and maintaining a healthy, moisture-controlled environment.

UV Light Protection

Preserve your interiors while maximizing daylight. 

Three panes of glass, selective coatings, and inert gas fillings work together to filter harmful UV rays while flooding your spaces with natural light. Your furnishings, artwork, and fabrics stay vibrant longer, while you enjoy the benefits of bright, naturally lit interiors.

Finding Your Perfect Solution

We believe in matching performance to purpose. 

Our team works with you to specify the ideal solution for your specific needs and vision, meeting whole-building thermal efficiency, budget, and noise concerns to select the best products for your project. 

When you choose alu-clad timber windows, you combine natural beauty with modern performance.

Norrsken’s alu-clad timber construction delivers the authentic warmth and character of premium timber with the durability and design freedom of virtually maintenance-free aluminum protection. creating windows and doors engineered for decades of exceptional performance and timeless beauty.

Double or Triple-Glazed?

Buildings reach their full potential with windows and doors that match their thermal envelope, architectural character, and their occupants’ lifestyle needs. 

While triple glazing delivers exceptional performance in well-designed energy-efficient homes, our high-performance double glazing provides an excellent solution where different priorities take precedence. Key considerations to guide your decision include:

Investment

Bespoke triple-glazed windows typically cost more than double-glazed windows.

Our triple-glazed windows typically represent a 10-15% investment increase over double glazing, yet deliver 40-45% better thermal performance - exceptional value for meaningful comfort improvement. This modest uplift delivers long-term benefits through reduced energy costs, enhanced property value, and the lasting satisfaction of optimal home comfort.

Long-Term Benefits

Superior performance pays dividends over decades.

Triple glazing transforms your home's efficiency through superior insulation that reduces heating and cooling costs year after year. Beyond energy savings, you'll benefit from reduced maintenance requirements and enhanced property value - making the decision as much about long-term peace of mind as immediate comfort.

Structural Considerations

The additional glass pane in triple glazing creates heavier units that require thoughtful structural planning, particularly for larger windows and doors.

Factors to consider include: 

Window Size:

Weight increases with the unit size, so larger triple-glazed windows and doors require more planning to manage and install.

Building Structure:

Ensure your home's structure can handle the additional weight of triple glazing.

Installation:

Factor in potential difficulties during installation due to weight. Norrsken provides a full supply & installation service to give you complete peace of mind for your new windows and doors.

Opening Mechanisms:

Choose appropriate opening mechanisms that can handle the heavier windows.

While triple glazing offers excellent benefits, its weight is a key consideration during the decision-making process. Carefully evaluate your specific situation regarding window size, building structure, and installation feasibility to ensure successful implementation.

Design Excellence

Choose the aesthetic that brings your vision to life. 

Both double and triple glazing are available in pure timber or alu-clad timber configurations, each offering distinct character. Pure timber with painted finishes, clear lacquer, or stain showcases natural warmth and authenticity, while alu-clad timber provides sleek, contemporary lines with virtually maintenance-free performance.

Your Questions Answered

Have a question? You're not alone. We've answered some of the most common questions about below, drawing from years of expertise helping homeowners and professionals achieve their vision.

Why should I choose triple glazing? 

The thermal performance of a triple-glazed window is typically 40-50% better than a double-glazed version – reducing carbon emissions and heating bills - but costs on average only 10-15% more.

The inside pane stays 2.5-3 degrees warmer over its whole surface than a double-glazed window, giving a much more comfortable feel inside the room. 

Are triple-glazed windows expensive?

Bespoke triple-glazed windows cost more than double-glazed or uPVC windows.

Prices depend on the model selected, size and shape, and requirements for additional services such as installation. But the uplift in cost from our double to triple-glazed range is about 10-15% which, given their 40-45% increase in thermal performance, we believe is worth the investment.

Are triple-glazed windows soundproof?

Triple glazing reduces noise by physically blocking sounds. Most customers report noticeably quieter homes with triple glazing installed.

In our laminated glass units, a thin layer of polyvinyl butyral resin (PVB) bonds glass sheets together. Originally used for safety and security, laminated glass also provides excellent acoustic performance by dampening sound waves.

Are triple-glazed windows good for the environment? 

Norrsken customers achieve high energy efficiency in the home without compromising on style or quality.

Using our innovative triple-glazed windows and doors as part of your new build or refurbishment project can contribute to a significant reduction in your home's CO2 emissions and a useful reduction in your heating bills.

Buildings account for approximately 39% of global carbon emissions - so building to an energy-efficient specification, monitoring and limiting energy usage and installing triple-glazed windows with low U-values will all contribute to reducing carbon emissions from the built environment.

How are triple-glazed windows sustainable?

The thermal performance of our triple-glazed windows is normally 40-50% better than double-glazed equivalents.

Using our windows can contribute to a significant reduction in your home's CO2 emissions and a reduction in your heating bills. We only use FSC and PEFC certified timber and work with partner manufacturers awarded ISO 14001 qualification.

How long do triple-glazed windows last?

There is no set lifespan for triple-glazed windows. With good care, they can last from 20 to around 50 or more years – particularly if clad externally in aluminium.

The glass in a triple-glazed window may need to be replaced sooner as its gas filling can escape over time, compromising the thermal performance of the window.

Do triple-glazed windows meet UK building regulations?

Triple-glazed windows may help you to meet parts of the UK Building Regulations with greater ease.

Part F, Part O and Part L require windows and doors to meet certain requirements to ensure UK homes are well-ventilated, energy efficient and do not overheat.

With Norrsken triple glazing, you can meet the new regulations with ease and be supported by our knowledgeable team of experts. 

How are triple-glazed windows and doors installed?

Most Norrsken customers opt for a supply & installation contract to ensure that each installation is managed with great efficiency and our clients obtain the most energy-efficient installation to complement their windows and doors.

Maintenance requirements are very similar for triple and double-glazed windows and doors, and opting for alu-clad timber means near-zero maintenance.
