Aluminium vs uPVC Windows in the UAE: Which is Better? | Raihan Aluminium & Glass
1. Clean tracks and frames quarterly
Sand collects in sliding tracks and stiffens the rollers. Vacuum out the tracks every 3 months, then wipe with a damp microfibre cloth. A small drop of silicone spray on the rollers keeps them gliding.
2. Inspect rubber gaskets annually
EPDM gaskets seal the glass into the aluminium frame. Check for cracks, gaps or shrinkage — especially on south-facing windows. Replacement gaskets are inexpensive but stop draughts and AC loss.
3. Lubricate hinges, locks and rollers
Use silicone-based lubricant — never WD-40 or oil-based products that attract sand. Apply to hinges, multi-point lock mechanisms, sliding rollers and tilt mechanisms once a year.
4. Re-silicone external joints every 5–7 years
Around the outside frame, silicone seals the gap between window and wall. UAE sun degrades silicone faster than most climates. Have it inspected at year 5, replaced at year 7–10.
5. Don't pressure-wash
Direct high-pressure water can force water past gaskets and cause internal corrosion or stains. Hand-wash with mild soap and rinse with low-pressure water.
6. Watch for hairline cracks in glass
Particularly after a sandstorm or impact. A small crack in tempered glass can spread quickly under thermal stress in UAE summers. Replace promptly.
When to call a professional
- Sliding window suddenly won't move smoothly
- Visible water entering during rain
- Cracked glass
- Lock mechanism stuck or broken
- Frame paint blistering or pitting (rare on quality powder coat)
FAQ
How often should aluminium windows be serviced?
For most UAE homes — once a year is enough. Coastal villas may benefit from twice-yearly inspection.
Can rust appear on aluminium?
Pure aluminium doesn't rust. White oxidation can appear on damaged powder coat — usually fixable with re-coating.
Do you offer annual maintenance contracts?
Yes — AMC includes scheduled visits, lubrication, gasket inspection and discounted parts/labour for repairs.
Need Window Servicing?
One-off repair or annual maintenance contract.
