Everything You Need To Know About Window Grills

Window grills are bars used for decorative purposes, placed in between the panes of a window to match the aesthetic of the windows or to simply give the window a unique look. Home owners use window grills to make their windows look unique and stylish and stand out from the rest of the homes. A number of window manufacturers in Singapore offer a variety of choices when it comes to the design and type of grill, but it is entirely upon the home owner to decide on the layout or style, as well as how the grills will look with the windows of their houses. Grills are paced in between the panes of the window during installation time so that they do not interfere with cleaning and maintenance process of the glass or the effectiveness of emissivity coatings.

The Layout of window grills
A home owner or designer has several choices regarding how the window grills will look after installation. These choices include colonial, prairie, ladder and double ladder. These are the most preferred layouts for replacement windows panes. The most common grill styles for Singaporean home owners is prairie and colonial styles. Colonial style is preferred by home owners who would like their tall and narrow windows to look a bit more wider, or in cases where the home owner would like a panel look. Prairie style gives the window a great frame effect especially when it is designed in a golden or metallic color from vinyl. But it is entirely upon the home owner to decide on the best grill style for their home, according to their imagination.

Window Grill styles

Just like it is in the case of grill layout, there is also a number of colors, sizes and styles that a home owner can adopt. It is common for window manufactures to carry grills that are in the same color with the windows, with an option of golden, metallic or silver finishes. A window grill can be either flat, circular or adopt a protruding edge design. The sizes range from a quarter inch for circular grills to 13/8 inches for flat window grills. Window that have wider panels have their grills manufactured from aluminium while those with thinner panes come with plastic grills. Grills are one of the few areas where a home owner gets to customize their own windows, therefore manufactures accommodate a variety of choices so that they can appeal to different tastes of their customers.

Problems Associated with window grills

Matching the Grills with the windows

This is one of the biggest problem for home owners. Getting to match the window grills to different window in your home is daunting especially if you are installing them in an already built home. However, this is not a major problem if your windows are all in the same profile (height of the frame). But if different windows in your home have been installed in different profiles, the grills will in turn look different on their respective windows. It is important to discuss the window profiles with your project consultant if you are considering window grills for replacement windows.

Efficiency of Energy

Installing grills on a window reduces it's energy efficiency. This is because the grill occupies the space inside the insulated unit, hence limiting the amount of sun that gets into your home. They also limit the amount of gas getting into the sealed unit, making the glass more susceptible to loss of heat than normal windows. This problem however, can be easily rectified by adding a low emission coating on the glass to improve the efficiency levels.

Falling Grills

This is a major post installation problem that happens when the gills fall out of place. When the window shifts and settles in the opening after is is installed, the grills are prone to coming apart from the sealed unit of the wall, and fall off. Most construction contractors have this problem covered in the window's warranty. Unfortunately, a fallen grill is not easy to fix. The only solution is a complete replacement of the whole sealed unit. Once again, make sure to discuss the terms of warranty with your contractor before you get new window grills.
