Window Glass Colours

Our aluminium framed glass windows can be made with different types of glass such as clear glass, frosted privacy glass, tempered glass, laminated glass and double glazed acoustic glass. We will recommend a suitable window type based on the opening size, ventilation needs, privacy requirements and site condition.

These glasses are all tinted colour glass.

From Left to Right: Tea, Light Grey, Dark Grey, Green, and Blue Colour.

Tinted glass can act as privacy glass during the daytime. During the day, people from outside cannot see through your tinted glass window into your room. This is because the tinted glass reduce the visibility from brighter side to the darker side. Whereas during the night when you turn on your light, your room becomes brighter, people outside will be able to see into your room.

From Left to Right: Karatachi, Clear, Mislite, Nashiji (Orange Skin) and Wire Glass.

All these glass (except for the clear glass) have frosted glass/ blurry effect, they are translucent, and also known as privacy glass.

For the window (aluminium) frame, we have many colours to offer, including bronze, silver anodised colour, white powder coated and more.

Your windows will be installed by our trained and certified window installers, who have many years of experience.

Casement Windows in Singapore

Casement windows are one of the most popular window types in Singapore for bedrooms, living rooms, kitchens and other areas where good ventilation and a wide opening are important.

Casement windows are swing open (push-out) windows. The window panels are supported by friction stays (window arms) at the top and bottom of the frame, allowing the window to open smoothly while holding the panels securely.

As required by HDB regulations and as a safety feature, we use stainless steel rivets and screws for all our windows.

Casement windows can be fully opened, providing a wide and unobstructed view of the surroundings. They also allow more air and natural light into the room, helping to improve ventilation and make the space brighter and more comfortable.

When closed, casement windows press tightly against the frame to form a more airtight seal. This helps to reduce external noise, making them more suitable for homes located near busy roads or noisy environments compared to sliding windows.

Casement windows are also practical for smaller openings where sliding windows may not be suitable, such as single panel windows near air-conditioning condenser units in HDB.

Sliding Windows in Singapore

Sliding windows are a practical and space-saving window option in Singapore, especially for HDB service yards, kitchens and other areas where outward-opening window panels may be obstructed.

Sliding windows are made with window panels that open by sliding horizontally along a track system. As they operate with tracks and rollers, sliding windows are simple to use, and the glass panels can usually be pushed and pulled smoothly with little effort.

The main advantage of sliding windows is that they are space efficient. Since the panels move sideways instead of swinging outward, they are suitable for areas where there may not be enough space outside the window for push-out casement windows.

Sliding windows are especially practical for locations such as HDB service yards. Many HDB service yards have laundry racks installed outside the windows, and these racks may obstruct casement window panels from swinging out. In this situation, sliding windows are often the better choice because they can be opened without interfering with the racks.

Because sliding windows move sideways instead of outward, the glass panels can usually be made wider than casement window panels. This allows for a broader outside view and less frame obstruction even when the windows are closed.

According to HDB guidelines, the maximum width of a sliding window panel cannot exceed 1.2m, while the maximum width of a casement window panel cannot exceed 0.7m.

Casement Windows vs Sliding Windows

Casement windows and sliding windows are both popular choices in Singapore, but they suit different needs. Casement windows can be opened wider and usually provide a tighter seal when closed, which makes them better for ventilation and sound reduction. Sliding windows are more space saving because the panels move sideways instead of outward, making them more suitable for HDB service yards, kitchens and other areas where outside space is limited.

Folding Windows for Kitchen Counters and Bar Counters

Folding windows are a popular option in Singapore homes for kitchen counters and bar counters, especially where homeowners want a wider opening between the kitchen and living area.

Many homes in Singapore have kitchen bar counters that connect the kitchen to the living room. This allows food and drinks to be passed through easily without stepping out of the kitchen, while also creating a more open and modern layout.

Folding windows (bi-fold windows) are ideal for this setup because the panels can be folded and stacked to one side. This creates a wide, almost fully open view with minimal obstruction, making the space feel more open and connected.

When closed, folding windows can also help to contain cooking smells, smoke and grease within the kitchen area, reducing the amount that spreads into the living room.

We use slim frames for our folding windows so that you can enjoy a clearer view even when the windows are closed. The larger glass panels also allow more natural light to pass through, making your home feel brighter and more spacious.

Full Height and 3/4 Height Glass Windows

Full height and 3/4 height glass windows are installed in Singapore for homes, offices and shops where larger window openings, more natural light and a wider outside view are preferred.

We supply and install full height and 3/4 height glass windows for residential properties such as HDB flats, condominiums and landed houses, as well as commercial properties including offices and retail shops.

For full height and 3/4 height window installations, we use larger aluminium profile frames that are specially designed to support bigger glass panels. We also use laminated glass for the bottom fixed panels to improve safety and durability.

We also install full height windows for HDB maisonette balconies. These balcony window structures often include a bottom row of casement or sliding windows, followed by a support beam above, and then a second and third row of top hung or sliding windows.

Due to the height of the upper window rows, scaffolding may be required for installation.

Lattice Glass Windows

Lattice glass windows, also known as lattice windows, are a distinctive window design in Singapore for homeowners who want a more decorative appearance together with added privacy.

A lattice glass window is made up of multiple smaller glass panes divided by crisscross or grid-like window bars. This design can be used for both casement windows and sliding windows, creating a more elegant and decorative look compared to ordinary plain glass windows.

Lattice windows are suitable for both modern homes and heritage-style properties that require a more classic, traditional or colonial-inspired appearance.

The lattice design also helps to reduce direct visibility through the glass, making it more difficult for outsiders to see clearly into the home. This is especially useful for HDB flats with corridor-facing windows or homes located close to the street.

For better privacy, lattice windows can also be installed with tinted glass or frosted glass.

Lattice windows may also provide an added sense of security because the lattice bars create an extra layer within the window design. When paired with window grilles, they can make forced entry more difficult.

We also supply and install lattice glass doors. Please visit our Lattice Doors Gallery.

Top Hung and Adjustable Louvre Windows

Top hung windows are commonly used in Singapore for bathrooms and toilets, while adjustable louvre windows are often used for bathrooms, toilets and corridor-facing areas where ventilation and privacy are important.

Top hung windows open outward from the top, allowing air to flow in while helping to keep out rain. They are suitable for areas that require ventilation even during wet weather.

Adjustable louvre windows consist of horizontal glass panels (also known as blades) held together by U-channels. The panels can be tilted open or closed using a lever handle, allowing you to control airflow and ventilation easily.

Louvre windows are ideal for ventilation because the angle of the panels can be adjusted. This is especially useful when the window is exposed to rain, as you can tilt the panels to let fresh air in while reducing the amount of rainwater entering.

For better privacy, aluminium slat panels can be used instead of glass panels, or combined with glass panels. This is commonly used for HDB corridor-facing windows where you may want to block direct visibility while still allowing light and airflow into the room.

Windows FAQ

1. What is the best window type for HDB flats in Singapore?

The best window type for an HDB flat depends on the location, available space and ventilation needs. Casement windows are commonly used for bedrooms and living rooms because they can open wider and provide a better seal when closed. Sliding windows are often preferred for service yards and kitchens because they do not require outward space to open. Top hung and adjustable louvre windows are also suitable for bathrooms, toilets and corridor-facing areas where ventilation and privacy are important.

2. Which comes first during renovation? Window or window grilles?

Windows are usually installed before wall plastering and painting are done. While window grilles are installed after the wall painting is completed. On our side, we will wrap our grilles with protection sheets after installation so that the grilles will not be affected by any painting works.

3. After I order the windows, how long does installation take?

Usually preparation and fabrication take around 2 to 3 weeks. Installation can usually be completed within 1 to 2 days.

4. I stay in HDB, can I choose whichever window type and colour I want?

For HDB flats handed over from 1st July 2007 onwards, according to HDB guideline, installation or replacement of new windows will need to follow the window configuration and colour originally provided by HDB.
For service yard windows, the colour generally needs to follow the original window provided by HDB.

For older HDB flats (handed over before 1st July 2007) there is no restriction, homeowners can choose their preferred window types and colours.

We also supply and install window grilles that can be added to your windows for extra security. Please visit our window grill pages:
Slim Mild Steel Window Grilles – slim-profile grilles that provide security with minimal obstruction to your view.
Wrought Iron Window Grilles - Traditional decorative grilles that are strong, durable and highly secure.
Aluminium Window Grilles - Lightweight, simple and cost-effective grilles that are easy to maintain.
