The Property Masters designs, supplies and installs windows across Dubai — and in this climate the window is an energy decision, not just a view. The combination that matters is double glazing (two panes with an insulated cavity) plus a Low-E coating that reflects solar heat, set in either an insulating uPVC frame or a thermal-break aluminium frame. Done right, this cuts heat ingress, lowers your DEWA cooling bills and quietens the home — all to Dubai Municipality standards, priced by a fixed quote after a free site visit.
Why double glazing is essential in Dubai
A single pane of glass is a thermal hole in your home.
- Double glazing two panes separated by an insulated (often argon-filled) cavity — dramatically slows heat transfer
- 60–70% reduction in heat ingress vs single glazing — eases AC load directly
- Less heat in = AC runs less = lower DEWA bill every month
Low-E glass — the Dubai-specific spec
The single most important glass upgrade in this region.
- Low-E (low-emissivity) coating microscopically thin metallic layer that reflects radiant solar heat back outside while still letting light through
- Dubai's challenge is solar heat gain, not retaining warmth — solar-control Low-E is what keeps interiors cool
- We specify the glass to the orientation of each window — a west-facing elevation taking afternoon sun needs more aggressive solar control than a shaded north face
Frames — uPVC vs thermal-break aluminium
The frame matters as much as the glass — a metal frame can conduct heat straight past good glazing.
- uPVC naturally insulating, low-maintenance, cost-effective; strong thermal and acoustic performance — excellent value for villas and apartments
- Thermal-break aluminium insulating polyamide bar between inner and outer aluminium sections stops heat bridging through the metal; slimmer sightlines and larger spans for a contemporary look while still performing thermally
- Standard aluminium (no thermal break) avoid in Dubai — heat travels straight through the frame and the AC works harder
Acoustic comfort
- The same insulated cavity that cuts heat also markedly reduces outside noise
- For bedrooms and home offices we can specify an asymmetric or acoustic laminated build-up targeting noise as well as heat — valuable near roads, communities and flight paths
Meeting Dubai's standards — and community rules
- Dubai Municipality and Dubai Central Laboratory (DCLD) requirements apply; U-value limits broadly 1.5 W/m²K residential / 1.2 W/m²K commercial
- Changing an external window is usually not a free choice — most communities and developers restrict exterior alterations; approvals required
- We flag this early, before the order
Survey, supply and installation
- Every opening surveyed and measured — windows are made to measure
- Glass and frame recommended per orientation and use
- Installed with proper sealing, correct fixing and weatherproofing — no thermal gaps or leaks around the frame
- Opening lights checked to operate smoothly and lock securely
How windows fit your scheme
Windows share hardware finishes and sightlines with your doors and frame the wall treatments around them. Usually part of a wider interior fit-out — explore the full range on our interior design hub.

Frequently Asked Questions
Do double glazed windows reduce DEWA bills in Dubai?
Yes. High-performance double-glazed units can reduce heat ingress by around 60–70% compared with single glazing, and adding a solar-control Low-E coating cuts it further. Less heat entering the home means the air-conditioning runs less, which directly lowers monthly DEWA cooling costs. The exact saving depends on orientation, glass and frame.
What is Low-E glass and why does it matter in Dubai?
Low-E (low-emissivity) glass has a microscopic metallic coating that reflects radiant solar heat back outside while still letting light through. Because Dubai's challenge is solar heat gain rather than retaining warmth, a solar-control Low-E coating is the single most effective glass upgrade for keeping interiors cool and reducing AC loads.
Should I choose uPVC or aluminium windows in Dubai?
uPVC frames are naturally insulating, low-maintenance and cost-effective with strong thermal performance — excellent value for most homes. Thermal-break aluminium offers slimmer sightlines and larger spans for a modern look while still performing thermally. Standard aluminium without a thermal break should be avoided, as heat bridges straight through the frame.
Do I need approval to change external windows in Dubai?
Usually, yes. Most communities and developers restrict changes to a building's external appearance, and glazing must also meet Dubai Municipality and Dubai Central Laboratory standards, including U-value limits. Any change to external windows should be carried out to the relevant authority and community requirements, with approvals obtained where needed. We flag this early.
How much do double glazed windows cost in Dubai?
Windows are made to measure and priced per unit, varying with size, the glass specification (double glazing, Low-E, acoustic) and the frame — thermal-break aluminium typically costs more than uPVC.
