What Is a Casement Window?
A casement window is a window panel attached to the frame by side hinges, allowing it to swing open inward or outward like a door. It is commonly operated using a handle, latch, or friction stay for smooth opening and secure closing.
Many homeowners may not be familiar with the term casement window. In Singapore, it is more commonly known as a swinging window or hinged window because the window opens by swinging on its hinges.
Regardless of the name, casement glass windows remains one of the most popular window choices for HDB flats, condominiums, landed homes, and commercial properties due to its practicality, ventilation, and timeless design.
Why Casement Windows Are Popular in Singapore
1) Excellent Ventilation and Natural Light
Casement windows open wide on side hinges, allowing maximum airflow into your home—perfect for Singapore’s humid climate. They also let in more natural light compared to sliding windows, which are partially blocked by overlapping panels.
2) Sealed Design for Insect Control, Better Sound Insulation, and Wind Resistance
Unlike sliding windows, casement windows close tightly with no visible gaps. This helps prevent insects from entering, improves sound insulation, and eliminates rattling during strong winds—making them ideal for high-floor or windy locations.
3) Enhanced Durability with Secure Locking Systems
Our casement windows are crafted from high-quality aluminium and fitted with stainless steel hinges or friction stays, along with durable handles for long-term reliability. For added strength and security, homeowners can opt for our Euro profile casement windows, which feature thicker frames and a multipoint locking system for superior protection and performance.

Aluminum Casement Window Design & Style In Singapore
When homeowners in Singapore talk about casement window design and style, they are often referring to the lattice pattern on the glass panels. Lattice casement windows create a timeless, elegant look and are especially popular in landed homes, condos, and selected HDB renovations.
Unlike plain glass casement windows, lattice designs add character and make the window look more decorative from both inside and outside the home.
Popular Lattice Casement Window Designs
The 6 panel lattice design is one of the most popular choices in Singapore. It offers a balanced and symmetrical appearance without looking too crowded.
The 8 panel lattice design is another top choice for larger windows. It gives a premium, heritage-inspired look and works well for wide openings.
In Singapore, 4 panel lattice designs are less commonly chosen. One reason is cultural preference, as the number 4 sounds similar to the word associated with death in Chinese. Because of this, many homeowners prefer 6 or 8 panel layouts instead.
Is Lattice Casement Window Suitable With Window Grille?
Lattice casement windows already have visible lines across the glass. If you also install a window grille, the overall look can become too busy or cluttered.
Things to Consider Before Choosing Lattice Windows
Higher Cost
Lattice casement windows usually cost more than plain casement windows because of the extra fabrication work and detailing.
More Cleaning Needed
More bars and sections mean more surfaces to wipe and maintain. Dust can collect around the lattice lines, so cleaning takes longer compared to plain glass windows.
Less Popular Than Plain Minimalist Designs
Many newer homes in Singapore now prefer slim frame and plain glass designs for a cleaner modern look. Lattice windows remain popular mainly for homeowners who prefer a classic style.
HDB Casement Windows Guideline in Singapore
When installing casement windows in HDB flats, it is essential to follow specific regulatory requirements to ensure safety, compliance, and long-term performance. Before any window replacement work begins, homeowners must engage a BCA-registered and HDB-licensed contractor, who will handle the HDB permit application on their behalf. Below are three key guidelines to consider:
1) Casement Window Location Restrictions In HDB
Casement windows are not allowed along common corridors or in ground-floor units. This rule helps prevent obstruction in shared spaces and reduces safety risks for neighbours and pedestrians.
2) HDB Casement Window Size Specifications
HDB regulations require each casement window panel to be between 500 mm and 700 mm in width.
-
Wider panels may place too much stress on the hinges, reducing durability over time.
-
Larger openings without window grilles can also pose a fall risk, as homeowners may need to lean out to close the window fully.
3) HDB Casement Window Hardware Requirements
HDB mandates the use of stainless steel grade 304 friction stays, which offer superior rust resistance and strength.
At Ho Ho, we use:
-
Grade 304 stainless steel
-
2.50 mm thickness
-
Friction stays that are at least half the width of the window panel
This ensures long-term durability and smooth operation.
In contrast, some suppliers may cut costs by using cheaper grade 430 friction stays at only 1.8 mm thick. While more affordable, these parts are less resistant to corrosion and significantly reduce the window’s overall lifespan and performance.
At Ho Ho, we take pride in being a trusted supplier who always puts our customers first. With over 50 years of experience in the industry, we understand that delivering high-quality products at fair prices is the key to long-term success in a competitive market. Our unwavering commitment to excellence has earned us a loyal base of repeat customers who continue to entrust us with their homes.
For the latest guidelines, please refer to the official HDB website.

For even better noise reduction, opt for our soundproof window upgrade for a quieter, more restful space.
Casement Window With Top Hung
Some casement window configurations include a top hung window panel above the main window. This feature allows for continuous ventilation—even during rainy weather or when you're away from home. It's particularly useful for kitchens or non-air-conditioned bedrooms that require steady airflow.
However, keep in mind that adding a top hung panel will reduce the height of your main casement window, which can make the window feel shorter and limit the overall view.
If you don’t plan to use this feature often, it’s generally best to leave it out.
Note: Including top hung for your casement window will incur additional cost.
Special Casement Window
Casement Window Pricing in Singapore: What to Expect
Casement windows can be uniquely customised to suit different architectural styles and functional needs. Below are some special variations:
1. Lattice Casement Window
Featured in the first image, this window incorporates decorative lattice bars that add a classical or colonial charm. It's a popular choice for homeowners looking to infuse a country or vintage European touch into their interiors.
2. Casement Window with Bottom Fixed Panel (Bay Window)
The second image shows a casement window with a fixed glass panel at the bottom—commonly used for bay window setups. This design allows you to enjoy extended views while keeping the lower section static for safety and structure.
3. Picture Casement Window
The third window setup combines a large fixed centre panel (picture window) with side casement panels that can open. This design maximises natural light and views while still allowing for airflow through the smaller casement openings.
4. Semi-Circle Casement Window
The last image features a semi-circular (arched) casement window, adding a soft architectural focal point. Often used in bathrooms or stairwells, it balances privacy and design elegance—especially when paired with frosted glass.
Casement Window Handle
A casement window handle is an important component that controls the opening, closing, and locking of your window. If the handle becomes loose, broken, or difficult to turn, replacement may be needed to restore smooth and safe operation.
At Ho Ho, we offer improved handle options for our own customers using stronger and more reliable designs.
Why Our Default Casement Window Handle Is Better
