Why It’s Important to Choose a Good Quality PVC Thermal Insert When Manufacturing Windows

The Importance of Quality Within Every Window

When manufacturing high-performance PVC windows, every component has a role to play. While glazing, seals and outer frames often receive the most attention, the PVC thermal insert is an equally important part of the overall window system.

A high-quality thermal insert can contribute to the strength, stability and thermal performance of a window, while a poor-quality insert can compromise the finished product and ultimately affect customer satisfaction.

With energy efficiency becoming an increasingly important consideration for homeowners, developers and installers, window manufacturers need to be confident that every component they use is manufactured to a high standard.

In England, current Building Regulations guidance under Approved Document L places significant emphasis on the energy performance of windows, with window U-values assessed based on the combined performance of the glazing and frame.

What Does a Thermal Insert Do?

A thermal insert is an important component within the window profile, helping to improve the performance and integrity of the finished frame. It needs to withstand the demands placed upon it during manufacturing, installation and throughout the lifetime of the window.

This means manufacturers cannot afford to overlook the quality of the insert.

A reliable thermal insert should offer consistent dimensions, dependable screw retention and long-term durability. It must also be capable of withstanding the everyday stresses associated with window manufacture and installation without compromising the finished product.

Research into PVC window construction has also highlighted the importance of profile design and reinforcement in reducing thermal bridging and improving the thermal performance of window structures.

Why Choose AT Extrusions?

At AT Extrusions, quality starts with the manufacturing process.

Our PVC thermal inserts are extruded in-house using 100% recycled material, giving us greater control over the production process and the consistency of the finished product.

Our thermal inserts have undergone screw retention testing, giving customers additional confidence in their performance during the manufacturing and installation process. They are also designed with a 30+ year lifespan, making them a dependable choice for window systems where longevity matters.

For manufacturers, this reliability can make a noticeable difference on the production line. Consistent, high-quality inserts can help provide confidence during assembly, reduce concerns surrounding component failure and contribute to a quality finished window.

Built for Long-Term Performance

Windows are expected to perform for decades. Once installed, they are exposed to changing temperatures, weather conditions, repeated use and the everyday demands of a modern home.

That is why selecting a component based purely on initial cost can be a false economy.

A thermal insert that is manufactured to a high standard and designed for long-term performance helps manufacturers produce windows they can be confident in. With AT Extrusions’ 30+ year lifespan, manufacturers can offer their customers a component designed to stand the test of time.

This is particularly important when customer expectations are high. Homeowners want windows that look good, perform well and continue to do their job years after installation. A quality-focused manufacturing process helps deliver that confidence.

Quality You Can See Throughout the Manufacturing Process

The benefits of choosing a quality thermal insert aren’t limited to the finished window. Manufacturers can notice the difference during production too.

From consistent extrusion and reliable dimensions to tested screw retention, every detail matters when multiple components need to work together accurately. A dependable insert helps manufacturers maintain confidence in their assembly process and the quality of the finished product.

At AT Extrusions, our approach is simple: manufacture quality products, control the process and build for longevity.
