What's the best way to seal leaky windows in Dubai?« Back to Previous Page

As a certified building environmental specialist operating in Dubai for over a decade, addressing window leakage is a critical step for energy efficiency, especially in a high-heat area like Al Barsha. The constant AC strain you're experiencing is a classic symptom of poor thermal envelope integrity.

The most effective and affordable initial remedy is to apply high-performance weatherstripping. For the UAE climate, I specifically recommend EPDM (Ethylene Propylene Diene Monomer) rubber seals. They offer superior resistance to our intense UV radiation and extreme temperature fluctuations without degrading like cheaper foam tapes. For the gaps you're feeling, a self-adhesive V-strip or tubular gasket is ideal for the window sash and frame interfaces.

For larger, irregular gaps between the window frame and the wall itself – a common issue in villa construction – a silicone-based acrylic latex sealant is the go-to. Ensure it's rated for exterior use and has a high UV resistance. Apply it only after a thorough cleaning of the surface with isopropyl alcohol to ensure proper adhesion.

It's crucial to note that while DIY sealing can offer immediate relief, persistent high bills often indicate deeper issues like inadequate insulation or potential ductwork leakage in the attic space, which a visual inspection won't catch. For a comprehensive assessment of your villa's overall energy efficiency and to ensure compliance with Dubai's Green Building regulations, a professional thermal imaging inspection is highly advised. We can identify all the hidden thermal bridges and energy drains.
