Exploring how warm edge spacers are used in today’s glazing is interesting. These spacers help make windows more energy-efficient by reducing heat transfer at the edge of an insulated glass unit, minimising heat loss through the glass and making homes and buildings feel more comfortable. Warm edge spacers have changed how we look at thermal efficiency and sustainability in building design and this is especially true with modern glazing solutions for homes and large commercial buildings that require high thermal performance.

What makes warm edge spacers essential in modern construction?

The push to use less energy has made warm edge spacers very important in today’s buildings due to their ability to help:

Windows have good thermal insulation from outside heat or cold

Play an important role in keeping a steady indoor climate

Make homes feel more comfortable and save energy

Lower energy bills for occupants

Lower the risk of condensation on your windows

Residential applications: Enhancing home comfort

In homes, warm edge spacers play a key role in improving thermal insulation and lowering energy costs. A good example is Super Spacer®, which can be used in double glazing or triple glazing systems. It reduces heat loss through the window frame and the edge of glass so homeowners feel more comfortable and save money on heating bills as time goes by. Plus, using these spacers also helps cut down on carbon emissions, allowing homeowners to have an energy-efficient and sustainable home.

Commercial buildings: Meeting advanced performance requirements

Many commercial buildings must meet strict performance goals, including energy efficiency and environmental standards. Warm edge spacers can help buildings reach these high standards.

Commercial buildings feature a lot of glass when compared to homes, which can allow heat to escape. Warm edge spacers help keep the heat inside by reducing the thermal bridge between the interior and exterior. Products like TriSeal™ and T-Spacer™ are made to tackle these issues and improve thermal bridge reduction and offer great durability for large commercial buildings.

Warm edge spacers application in extreme climate conditions

The use of warm edge technology is great for places with very cold or hot weather. Warm edge spacers, such as Super Spacer®, can handle temperatures ranging from -40°C to 85°C. This makes them effective and reduces the risk of condensation in all types of weather.

Specialised applications

Warm edge spacers are found in many buildings, including tall skyscrapers and homes. They are flexible, which means they can fit different design needs. This flexibility allows people to create unique glazing solutions. Additionally, these spacers help maintain good thermal performance and provide a solid structure.

Advanced solutions for triple glazing systems

In triple glazing, warm edge spacers are very effective. They maintain the correct distance between the glass panes. They also improve thermal efficiency. Their clever design keeps gas inside and makes them durable. This is why they are great for high-quality glazing systems.

These spacers really help to reduce heat transfer. This makes triple-glazed windows better at keeping warm or cool air inside. It helps manage heat flow during both winter and summer. In turn, this can lead to energy savings and comfort throughout the year.

Meeting sustainability goals for different applications

Create solutions that are good for the environment are key to reaching sustainability goals and warm edge spacers play a key role in building in a sustainable way by reducing carbon emissions and helping to save energy. Their improved performance makes buildings work better and supports green building projects and helps meet environmental standards.

Modern flexible warm edge spacers from Edgetech

Edgetech has different warm edge spacers that are perfect for homes and businesses. The Super Spacer® is ideal for home use. For commercial projects, both TriSeal™ and T-Spacer™ work well to keep up thermal efficiency.

Super Spacer® changed the window industry in 1989 as the first flexible foam spacer bar ever made, delivering much better thermal performance.

This pioneering warm-edge spacer requires no PIB adhesive application or pre-cutting into specific lengths, making installation more efficient. Its exceptional UV resistance ensures long-term durability, outperforming conventional spacers that may degrade under solar exposure.

For over three decades, Super Spacer® has maintained its position as an industry leader in thermal efficiency and has helped countless homeowners and businesses reduce their carbon footprint while maintaining optimal energy performance.

TriSeal™ is a special version of Super Spacer designed for commercial buildings. It features a ‘triple-seal’ design and has been used on ambitious projects all around the world. The triple seal includes an inner acrylic adhesive seal which allows the unit to be handled immediately, unlike other spacer products, which must be left to ‘set’. It’s polyisobutylene primary seal enhances gas retention, which is perfect for high-performance commercial settings, while its outer silicone seal provides structural strength and superior durability. T-Spacer™ is a version of TriSeal™ suited for automated spacer application.

Future-proofing glazing solutions

Warm edge spacers are becoming very important as building rules and energy laws change. They provide better thermal performance, which means they keep buildings warm efficiently, and are versatile and durable, making them suitable for many uses. Their role in improving energy efficiency and comfort in spaces is why they are essential in modern construction projects.

Edgetech’s warm edge spacers have a long track record of contributing to energy efficiency and being used on ambitious projects around the world, including for various architectural designs and climates, and as a Quanex company, Edgetech has huge resources and support, with Quanex boasting 31 manufacturing locations around the world.

Edgetech will continue to be the leader in warm edge spacers. They offer improved thermal features and eco-friendly glazing options for IGU makers, window builders, and architects. This highlights their commitment to the environment and their focus on innovation.

Frequently asked questions

What are warm edge spacer bars?

Spacer bars are small, thin rectangular strips designed to keep apart the two panes of glass in an insulating glass unit (IGU). An IGU is made of two panes of glass separated by a spacer, then sealed at the edges. Spacers serve a structural purpose – they keep the two panes apart, but they also contribute to the performance of the finished window.

Can warm edge spacers integrate with various frame materials?

Yes, while modern warm edge spacers work with different types of windows, such as double and triple glazing, they also complement different frame materials, including aluminium, uPVC, and wood. This versatility ensures the best thermal performance regardless of the chosen frame material, making them suitable for various architectural styles.

What are the cost and energy efficient benefits of warm edge spacers?

Warm edge spacers offer both cost and energy benefits. They are effective at thermal insulation. This means they lessen heat transfer and thermal bridging and as a result, heating costs go down. It also boosts overall energy efficiency. They can also stop condensation and frost, helping to protect windows and frames and increasing their lifespan.

What’s the difference between Super Spacer® and TriSeal™?

While both are warm edge spacers and keep windows sealed tight, Super Spacer® is designed primarily for residential applications. TriSeal™ is specifically engineered for commercial buildings, featuring a specialised triple-seal design with an inner acrylic adhesive seal, polyisobutylene primary seal, and outer silicone seal for enhanced gas retention and structural strength.
