Thermal-break and double-glazed windows

Standard aluminium conducts heat straight through the frame. A thermal-break profile splits the frame with a polyamide strip so the outside and inside never touch. Combined with double or Low-E glazing, it is the most effective way to make a sun-facing room cooler and quieter.

  • Thermal-break profile

    Polyamide barrier · insulated frame

    Stops heat travelling through the metal frame, which is where a standard window loses most of its performance.

  • Double glazed unit

    24 to 32mm · air or argon filled

    Two panes with a sealed gap in between cut heat transfer and outside noise.

  • Low-E coating

    Solar control · clear appearance

    A near-invisible coating that reflects a large share of solar heat while letting daylight through.

  • Acoustic laminated glass

    PVB interlayer · 6.8 to 10.8mm

    Added to one side of the unit for homes near highways, airports and construction.

Do thermal-break windows really lower electricity bills?

Windows are the weakest part of the building envelope, so improving them reduces how hard the AC works in every room that faces the sun. The saving depends on the size of the glass, the orientation and your current windows. Replacing single-glazed standard frames in west-facing rooms gives the biggest difference in comfort and in your DEWA, SEWA, ADDC or FEWA bill.

Is double glazing worth it without a thermal break?

Double glazing on a standard frame still helps, especially with noise. But the frame can make up a large part of a window's area, so a hot frame limits the benefit. If you are paying for double glazing on sun-facing rooms, we recommend matching it with a thermal-break frame.

Do I need insulated windows for green building rules?

New buildings in Dubai and Abu Dhabi follow green building regulations with limits on how much heat the glazing can let through. Your consultant sets the required values, and we supply systems and glass that meet them, with the data sheets for submission.

Frequently asked questions

Sometimes. If the frame is deep enough to take a double glazed unit, we can reglaze it. We check this at the site visit.

It greatly reduces condensation on the inside pane in humid months, because the inner glass stays closer to room temperature.

Double glazing with a laminated acoustic pane and good seals gives a clearly noticeable drop in traffic noise compared with single glass.
