Common BTO Window Types (Quick Guide)

Different parts of a BTO flat serve different needs, which is why window choice matters.

HDB Compliance Is Part of the Job, Not an Extra

HDB rules exist for safety, and following them properly avoids problems later. 

Our HDB-licensed work process covers: 

  • Handling the HDB permit application and submission on your behalf.
  • Installing certified aluminium frames and stainless steel rivets that meet BCA standards.
  • Using BCA-approved installation methods to reduce leaks, drafts, and compliance issues.

Some homeowners are surprised to learn that even minor window changes need approval; we see this almost every week.

Materials & Glass Options

Aluminium frames are commonly used in BTO flats because they meet HDB rules and hold up well in Singapore’s climate.

Clear glass is standard. Some homeowners may choose to install tempered glass or laminated glass for safety reasons, or frosted glass in bathrooms, while glass upgrades may also assist in reducing heat and noise.

Window Grilles for BTO Flats

Window grilles are not required for all BTO flats but are usually fitted for safety reasons, especially in flats with young children or pets.

If installed, the grilles have to comply with HDB guidelines in terms of design and color. They can be customised to suit different window types and planned together with your windows for a cleaner finish.

Frequently Asked Questions

Yes. A permit is required, and we handle the submission. HDB requires a permit for window replacement. As your licensed contractor, AT Aluminium manages the entire permit application at no extra charge, ensuring full compliance.

Windowsills must be at least 1 metre from the floor for most cases. If your BTO design has lower windows, it requires a Professional Engineer’s (PE) endorsement—a complex step we navigate for you to avoid delays.

Sliding windows are the most sought-after and feasible option for BTO service yards. As part of our complimentary site visit, we can determine whether a sliding window or a top-hung window would be most ideal for your space.

Window grilles are not mandatory for all BTO flats. Nevertheless, they are usually recommended for safety purposes, especially for families with young children, pets, or for those living in lower floors. If they are to be installed, the designs and colors must be approved by HDB. We help homeowners decide if grilles are necessary and ensure they are properly fitted and compliant.

HDB typically allows neutral colours such as silver or bronze to maintain a uniform building appearance. The exact colour may depend on your block’s guidelines. We will advise you on suitable colour options during consultation to ensure your window frames and grilles meet HDB requirements.
