Double Glazed Window Malaysia — Energy Saving & Soundproof

Double Glazed Window Malaysia

Double glazed windows (windows with two layers of glass) are getting more popular in Malaysia. But are they really worth it for our tropical climate? The short answer is that it depends on where your house sits and what you are trying to fix. A west-facing condo unit in Kuala Lumpur beside the highway will feel the difference from day one. A shaded single-storey terrace house on a quiet street may not. This guide walks through how double glazing works, what it costs with AluFrame, and how to decide whether the upgrade makes sense for your home.

What Is Double Glazed?

Double glazed means two layers of glass separated by a gap filled with air or argon gas. This gap acts as an insulator against heat and noise. The two panes are sealed together at the factory into a single unit, so it is not the same as fitting two ordinary windows one behind the other. Because the sealed unit is thicker than a standard 5mm pane, it needs an aluminium frame designed to carry it. AluFrame supplies double-glazed units in sliding, casement and fixed panel frames, and every window still comes with the same 10-year warranty on profiles and 5-year warranty on accessories.

Benefits in Malaysia

1. Energy Saving (Lower Electricity Bills)

• Reduces solar heat by up to 60%
• Your aircond does not need to work as hard as usual
• Saves 10-20% on your monthly electricity bill

In a Malaysian home the aircond is usually the biggest single item on the bill. Any window that faces the afternoon sun is effectively a heater for that room, and double glazing cuts the heat that reaches the interior glass surface.

2. Soundproofing

• Reduces outside noise by up to 80%
• Perfect for houses next to main roads
• Sleep more soundly

Traffic on the Federal Highway or an LDP flyover, a nearby surau loudspeaker, or a neighbour's renovation all come through a single pane of glass easily. The sealed gap breaks the path of the sound wave. For more on this topic, see our soundproof aluminium window guide.

3. Less Condensation

• Reduces condensation on the glass surface
• Prevents mould and mildew

When the aircond runs all night in a humid climate, the inside surface of single glazing gets cold enough for water to form. That is what leaves black spots on curtains and window sills in many condos. The inner pane of a double-glazed unit stays closer to room temperature, so condensation is far less common.

4. Security

• Harder to break, keeps burglars out
• Two layers of glass = double the protection

Pairing double glazing with a grille window frame (from RM320/unit) or tempered glass (add RM30-50/unit) gives you a ground-floor window that is both quiet and secure.

Double Glazed Aluminium Window Price in Malaysia

Size	Price (from)
4ft x 4ft (Sliding)	RM350
4ft x 4ft (Casement)	RM400
6ft x 7ft (Sliding Door)	RM700

If you are pricing from a standard window quote, the double-glazed upgrade adds RM80-150 per unit on top of the base window, which starts from RM180/unit for sliding and RM250/unit for casement. Installation is RM50-100 per unit, and removing old windows during a retrofit is included. Powder coat colours (from RM280/unit, 20+ colours) apply to the frame and are unaffected by the glass choice.

Worked Example: Two Front Bedrooms Facing A Main Road

A common request from terrace house owners in Selangor and Johor is to treat only the rooms that suffer, not the whole house. For two front bedrooms facing the road:

• 2 double-glazed sliding windows at 4ft x 4ft: from RM350 each, RM700 in total
• 1 double-glazed casement window on the bathroom side: from RM400
• Installation for 3 units: RM50-100 per unit, RM150-300 in total

That is a starting budget of roughly RM1,250-1,400 before colour and size adjustments, and the back of the house keeps its standard 5mm glass. A small job like this fits comfortably into a single day of installation.

Is It Worth It?

YES, if:

• Your house faces the afternoon sun (west)
• You live near a main road or noisy area
• You want long-term savings on electricity bills
• You live on a high floor (condo/apartment)

MAYBE NOT, if:

• Your house is shaded and noise is not a problem
• Your budget is very tight
• Your windows are rarely closed (always open)

One more Malaysian consideration: double glazing only works when the window is shut. If your family keeps the windows open for cross-ventilation most of the day, a louvre window (from RM200/unit) or a tinted upgrade (add RM20-40/unit) may solve the heat problem at lower cost.

What To Check Before You Buy

• Confirm the orientation of each window. Only the sun-facing and road-facing units usually justify the upgrade.
• Check strata rules if you live in a condo. Some management bodies specify glass tint or reflectivity for the external facade.
• Ask whether the sealed unit is argon-filled or air-filled and confirm the warranty in writing: 10 years on profiles, 5 years on accessories.
• Get a free site survey so the frame depth is measured correctly. Double-glazed units are thicker than 5mm glass and a wrongly sized frame cannot be corrected on site.
• Confirm coverage for your state on our aluminium window installation locations page.

Conclusion

Double glazed aluminium windows are a long-term investment. Even though the upfront price is higher, the electricity savings and improved comfort make them worth it. Treat the rooms that face the sun or the road first, keep standard glass elsewhere, and you get most of the benefit at a fraction of the cost of a whole-house upgrade.
