Thermally Broken Aluminum Windows Explained for Israeli Homes

t397-2

Thermally broken aluminum windows use a non-conductive insulating strip between the inner and outer aluminum sections of the frame, so heat cannot travel straight through the metal. This reduces heat gain in summer and heat loss in winter, which helps keep rooms cooler and lowers air conditioning demand. They are a practical choice for Israeli homes where long, hot summers make the frame a real factor in comfort.

What a thermal break actually is

Aluminum is an excellent conductor of heat, which is why a plain aluminum frame can feel cold in winter and hot in summer near the glass. A thermal break is a strip of low-conductivity material, usually a polyamide with glass-fiber reinforcement, that separates the exterior aluminum section from the interior one. The two halves are mechanically joined, so the frame stays rigid while heat flow through the metal is interrupted.

The result is a profile that behaves much more like an insulated element than a bare metal bar, while keeping the clean lines and durability that aluminum is known for.

Why it matters in Israeli homes

Across most of Israel the summer heat is long and intense, and sun shines directly on west and south facing windows for hours. A conductive frame allows that heat to move into the living space through the metal itself, not only through the glass. Air conditioners then work harder to keep up.

Less heat entering through the frame during the afternoon
More even temperatures near the window in summer
Reduced cold surfaces and condensation in cooler months

Thermal breaks are not a substitute for shading or good ventilation, but they make the window itself a better part of the overall climate strategy.

Glazing and profile work together

A thermally broken frame performs best when paired with suitable glazing. Double glazing with a low-emissivity coating and an inert gas fill improves the insulation of the glass unit, while the thermal break addresses the frame. Ignoring either part leaves a weak point, because heat will find the easiest route through the assembly.

Glass choice also affects solar heat gain. Coatings can reduce how much sunlight turns into heat inside the room, which is especially useful on sun-exposed facades.

Finishes and durability

Thermally broken aluminum profiles can be finished in a wide range of powder-coated colors, including the steel-look tones popular in modern architecture. The powder coating protects the surface from weather, salt air and UV exposure, which matters in coastal climates.

Because the frame is made to measure, the finish, color and sightline can be matched to the rest of the building. Ask for samples and check the coating under natural light before deciding.

What to check before ordering

When comparing options, ask for the detailed profile drawing and confirm that the thermal break is continuous through the frame, not only in one section. Check the glazing specification, the sealing system and how the window is installed in the opening, since poor installation can undo good materials.

Exact thermal performance values depend on the full assembly, so ask for the technical data relevant to your window size and orientation.

How the process works with us

We start with your inquiry and photos, then take the measurements on site so the window fits the opening precisely. A written specification and drawing are prepared for your approval before production begins.

Windows are manufactured to measure in our Tel Aviv factory and finished with the coating you select. Installation follows once everything has been checked, so you know exactly what is being built for your home.

Frequently asked questions

Are thermally broken aluminum windows worth it for hot climates?

Yes, in most cases they help reduce heat entering through the frame, which is useful in long Israeli summers. The benefit is greatest when combined with suitable glazing and shading.

Do thermally broken windows also reduce noise?

They can contribute to a quieter room, mainly because of the improved sealing and glazing, but noise performance depends on the complete window system. Ask for the specification if sound is a priority.

Can I choose any color for a thermally broken aluminum profile?

Yes, these profiles can be powder coated in a wide range of colors. Request samples and view them in daylight before finalizing your choice.

Do I need to measure the opening myself before ordering?

It is not necessary. We measure on site to ensure accurate fit, and you can send photos with your inquiry to start the process.

Common mistakes to avoid

A common mistake is choosing a good frame and then fitting cheap single glazing, which lets heat pass through the glass instead. Another is ignoring installation quality, since gaps and poor sealing can cancel out the benefit of the profile.

Our recommendation

Look at the whole window assembly: thermal break, glazing type and coating, and installation details together. For sun-exposed facades, discuss solar control coatings and shading with your installer before ordering.

Summary

Thermally broken aluminum windows reduce heat transfer through the frame and work best when paired with good glazing and proper installation. They are a practical upgrade for Israeli homes facing strong sun and high cooling demand.
