What is Thermal Break (RPT) and why do you need it in your windows?

If you are thinking of changing the windows in your home, you have probably heard of Thermal Breakage (RPT). But what does it really mean and why is it the quality standard in modern aluminum carpentry?

The aluminum “problem

Aluminum is an exceptional material for construction: it is light, strong, does not rust and is 100% recyclable. However, it has a natural characteristic: it is a conductive metal. This means that it easily transmits temperature.

In an old aluminum window (without RPT), the cold from the street “travels” through the frame into your home in winter, and the heat does the same in summer. This is called “thermal bridging”.

The solution: Thermal Bridge Breakage

The RPT consists of inserting an insulating material (usually glass fiber reinforced polyamide rods) between the outer face and the inner face of the aluminum profile.

In this way, we “break” the path of heat or cold. The metal on the outside and the metal on the inside never touch, creating an impassable barrier that keeps the temperature of your home stable.

4 Benefits you will notice from day one

1. Savings on your bills: By preventing heat or air conditioning from escaping, your HVAC systems work less. It is estimated that good carpentry with RPT can reduce energy costs by up to 30%.
2. Goodbye to condensation: Have you ever seen your windows “sweat” or water droplets on the inside in winter? That happens because of the temperature difference between the cold frame and the warm air inside. RPT eliminates this effect, avoiding humidity and mildew.
3. Greater acoustic comfort: Although RPT is thermal, the design of these profiles is usually more robust and airtight, which also helps to reduce street noise.
4. Bicolor finishes: Being a profile formed by two pieces joined by polyamide, you can choose a color for the outside of the window (to match the facade) and a different one for the inside (to match your decoration).

Conclusion

Today, installing aluminum windows with thermal break is not a luxury, it is a smart investment. They comply with current energy efficiency regulations and add value to your home.
