Aluminium Window in Singapore

Modern White Sliding Window in Singapore

When we are renovating our homes, we usually play a lot of attention on our sofa, bed, kitchen cabinets. We are generally willing to spend money on these items as we feel that it will is very crucial in setting the tone of our home renovation.


However, most homeowner in Singapore tend to overlook one of the very important element in our home decor - The aluminum glass window in your HDB flat. 

What are the different types of aluminium window available in Singapore? 

There are basically 6 types of aluminium glass window in Singapore

a) sliding window

b) casement window

c) fix lourve window

d) adjustable lourve window (corridor or toilet window)

e) combination window

f) top hung window (toilet window)

h) slide and swing window 

i) sound proof window

Each type of window has its own advantages and disadvantages. Depending on your usage and the location of the glass window, we will recommend different types of glass window.


Aluminium glass window installed in the living room of HDB BTO flat is an example of combination window. The window is made of 3 component; the top is top hung window, middle portion is a casement window and fixed panel for the bottom portion.  

The top hung window is to provide ventilation during raining days and the bottom part of fixed panel is to provide safety for your family member.

What types of window should I install for my HDB corridor unit?

Traditionally, adjustable or fix lourve window is installed at HDB corridor unit. This is because back in the days, families do not have air conditioner in the living room. Hence lourve window provide the most ventilation and privacy for the home owner. 

However, installing lourve window for your HDB corridor unit may not be ideal as lourve window provides the least sound insulation. In addition, if there is a nasty neighbour who smokes along your corridor, it will be a really terrible experience for you and your family member.

Hence installing sliding window for your living or bedroom along the corridor is more ideal.

Types of Aluminum Sliding Window in Singapore

There are 3 types of sliding window you can install for your HDB corridor unit:

a) standard sliding window

b) sliding window with top hung (provides ventilation) 

c) 2 section sliding window (provides more ventilation and privacy)

d) sliding window with adjustable lourve

In term of the cost, the cost for the standard sliding window is the cheapest follow by the sliding window with top hung and lastly the 2 section sliding window.

Advantages and Disadvantages Of Standard Sliding Window Along HDB Corridor in Singapore

  • Pros: Cheapest in term of pricing and least cleaning required 

  • Con: Less privacy as passer-by can look into the unit when the window is opened

# For privacy reason, most home owner will select frosted or tinted glass for their sliding window along the HDB corridor. Getting a clear glass sliding window along the corridor will required a curtain or blind to be installed for your privacy.

# It is important for homeowner to note that even though you may want to leave your top hung window permanently open, it is important to open and close the top hung once in a while so that the hinges will last longer. Like any other things, if something is not in use for a long time, it will be faculty.

  • Cons: It is the more costly type of sliding window as it require the material and labour hour

# Note: the top and bottom section must be equal in size or the top sliding window must be smaller in size in order to ensure that the bottom sliding window does not bear any weight it cannot withstand that will compromise on the durability of the sliding window

# For 2 section sliding window, HDB homeowner can also select different glass for the 2 section. The bottom section of the sliding window is usually privacy glass but the top section can be clear or light colour glass like blue colour.

Casement Window

Three most important requirements for newly installed casement window in HDB flat:

1) Casement aluminium window cannot be installed along the common corridor or units located at level 1 as the casement window may hit someone outside during opening

2) HDB requires the width of the casement window to be between 500 mm to 700 mm

3) Friction stay used in casement window must be stainless steel grade 304 with a minimum thickness not less than 2.50 mm and the length not less than 1/2 width of window leaf

For more information, you can read the full requirement of the casement window on the HDB website

One of the most common problem with old HDB's casement window installed is that they are too wide and exceed the new requirement of 700 mm. It is ideal to have the width of the casement window to be 700 mm or less as your friction stay will be more lasting due to less weight loading.

Casement window in HDB bedroom comes in either 2 to 6 panels. 


Casement window can come either with or without middle bar like the two photo above.


Most casement windows now do not comes with the middle bar for better view.For casement window without middle bar, you will have to latch if you have to close one panel and open one panel. 


However, for sound proof window, casement window needs to have middle bar for better sound insulation.

Even though sliding window is easier to maintain as there is no friction stay. Casement window is usually installed in kitchen as casement window provides a wider opening.

For example, 4 panel casement window offers full opening with only 1 middle bar. However for 4 panel sliding window, the opening is only 50%. Hence for homeowner who have 4 panel window and need to hang laundry outside the window, I will recommend casement window for their kitchen.

However, if your kitchen window is only 3 panel. Most homeowners will select 3 panel sliding window with 3 track as the opening 67%. For 3 panel casement window, there will be 1 middle bar. 

For L shaped kitchen window, you can choose the direction of opening to maximize the ventilation. 


Window in kitchen is usually covered with tiles. Hence it is recommended that you change the window in kitchen during renovation. For kitchen window installation during renovation, kitchen window must be dismantled and installed before tiling to avoid the tiling from cracking.

If you are replacing your kitchen window without doing tiling at your kitchen area, our window installers will be careful during dismantling process. However, due to the tiling method and the age of the tiles, surrounding tiles may be affected. Our window installer will patch up any affected tiles with cement. If tiling work is required, homeowner will have to engage their own tiler.

The frame and the glass colour of the casement window will significantly affect the look of the house. 


For brighter look, white frame casement window is highly recommended. Bronze frame casement window is very lasting but will make your window looks much darker. Hence if you do not have any west facing sun, you should always pair bronze frame casement window with clear, blue or glass glass for your house to look brighter.  

Casement Window With Fixed Panel For Private Properties (Condo & Landed)

If your wall below your window is less than 1 metre, it is advisable to have a fixed panel below your window for safety purpose especially if you are not planning to install window grille. To be safe, for fixed panel below, it has to be laminated or tempered glass. 

For HDB, fixed panel is generally not approved. For more details, you may contact your respective HDB officer. 

Homeowners may also consider fixed panel in the middle if you have a very nice view outside your window. However, this will significantly reduce your ventilation as only the side window can be opened. If you want the nice view but still be able to fully open the window. You may want to consider our slide and swing window

However, having combination window with casement window + fixed panel is definitely cheaper than slide and swing window.

Window For HDB Maisonette Balcony 

For HDB Maisonette balcony, the window is very tall. Hence homeowner can either choose to install window below and install blind above or install window for the whole height.

To install window for the full height, scaffolding is required hence the costing for installing HDB Masionette Balcony Window can be quite costly. Moreover, installing window at this height requires very skilled workers who are not afraid of height hence they are generally well compensated.

For bathroom window, you can either choose fix lourve, adjustable lourve or top hung window. 

Fixed lourve window is not recommended as it cannot be closed when needed and it is the oldest type of mechanism. 

Adjustable lourve is optimal if you want the bathroom window with the most ventilation.

However, the latest type of toilet window is top hung window. 

For HDB toilet window, wire meshed glass or laminated glass is required for safety. However, wire meshed glass is usually used as default. For laminated glass, you will need to top up for the cost difference but it will look better. 

Window in toilet is usually covered with tiles. Hence it is recommended that you change the window in toilet during renovation. For toilet window installation during renovation, toilet window must be dismantled and installed before tiling to avoid the tiling from cracking.

If you are replacing your toilet window without doing tiling at your toilet area, we will recommend you to retain the outer frame and have the new toilet window installed inside the old outer frame to avoid the tiles from cracking.

Regardless where you will install your aluminum window, we have the widest selection of material and mechanism for you to choose from.
