A window grill is a decorative grid pattern consisting of horizontal and/or vertical bars that divide a larger sheet of glass into smaller panes. Traditionally, a window grill, known historically as a muntin, muntin bar, sash bar, or grid was invented purely for ease of production and economical reasons. Smaller-sized pieces of glass were less expensive to manufacture, less likely to break, easier to manage and safer to ship than larger pieces of glass. As a result, gridded windows were invented and became the accepted style of window in many countries.
Grids can add that special touch to match a window or door to an architectural style, turning a large open pane into a dramatic statement. However, grid or grills as we will call them in this blog entry vary in pattern complexity and style which can be a consumer dilemma. This months story was written to help the consumer understand what grill options are available and as to whether a grill is something that should be considered for their new or existing home.
With the advent of modern glass-making procedures, it has become easier for window manufactures to produce larger, stronger, less delicate pieces of glass that can span an entire window frame and the development of multi-paned energy-efficient glass. So why grilled windows? The answer is purely aesthetics! The much loved traditional gridded window of the past did not fade away, so window manufactures find ways to appeal to their consumers. Thus, the invention of today’s window grills, available in all kinds of patterns, style types, profiles, thicknesses and materials.
Traditional window grids required the cleaning of each grid divider and glass pane individually. Today, a majority of multi-paned windows have the grills that are sandwiched between the panes, keeping the grids free of dust and making window cleaning so much faster and easier. Along with the gridded window’s aesthetic appeal and design, it packs benefits capable of lowering a home’s solar heat gain coefficient.
Grills are a great way to add style and elegance to your windows. And with today’s multiple window pane technologies, many manufacturers offer standard and custom configurations between the panes, and even simulated dividers on the exterior of the glass to provide a more traditional look.
As a homeowner, putting grills in your windows can make them look unique, however, when making a choice as to whether you should choose grills or not, you should first think of your home as falling into one of three categories: traditional, contemporary or modern.
Traditional and colonial-styled Canadian homes are homes that were built up to and around the late ’80s. These homes typically had gridded windows with classical style trim, porches, classical balusters and in keeping with the existing style of the home traditional gridded windows.
The term contemporary architecture is a standard phrase that essentially refers to the architecture of today. While there is no clear definition of what constitutes contemporary architecture, it comprises a range of building styles that often look very different from one another. Non-grilled windows are typically applied to contemporary homes to enhance lighting within and not to obstruct views to the outside.
While grids are great for traditional homes, non-grid options are a good choice for modern home upgrades. Bungalows, Ranch-style homes and modern neighbourhood homes look great with clean, un-gridded window styles.
Of course, there are no rules as to whether you should grill or not grill your windows, however, there are some considerations that could be taken into account. For example: if the view out of a window is very boring, a grilled window may make the view out more interesting; grilled windows are typically applied to the front of a home, not the sides or the back of the home; sometimes the view out of a window is so extraordinary that it should not be obstructed by a grill or busy grill pattern.
Many window manufacturers offer grill patterns to match your existing windows, of course, there are only a few patterns that are considered standard patterns with standard names. Window manufactures will often create their own unique grid names to separate them from the competition, so be sure to look at the patterns carefully.
The most popular style of window grill layouts is Prairie and Colonial style. Colonial styled grills are great for making tall, narrow windows look wider. Prairie grills can frame a large window nicely, making it more interesting.
Common Grill Patterns:
The most common grill option, these grid dividing systems sections are sandwiched between glass panes in dual and triple-glazed windows. They are easy to clean and can be colour matched to the colour of the window frame.
Simulated divided lites are grids are bonded to the window’s interior and exterior to give a window an old wooden separated windowpane traditional look. SDL creates the impression of true divided lites and brings heritage styling to traditional, contemporary and modern homes. For an even more authentic look, custom-fitted grills between the glass are offered as an option by most window companies (between the panes/exterior SDI, or true divided lites (TDL)).
Detachable grids are a great option offered by some window manufactures, although not typically available in the Ottawa area, these can be custom made to fit existing windows and can be applied or removed as the homeowner desires.
Windows manufacturers don’t make it easy for customers when it comes to picking grill widths - sizes often differ from one manufacturer to another. Architects will tell you that you need a certain thickness for a certain window dimension based on whether it is horizontal or vertical. The main goal for many manufacturers is to be able to match windows that you already have in your home, whether you are replacing one window, or all your windows. They usually range from as narrow as 1/4 in. for circular to 1 3/8 in. for flat grills.
Grills can be rectangular, circular, flat, or have a protruding edge, and they can be combined to create a certain look that could perhaps suggest a hung or sliding window.
Most window manufactures offer colour windows and colour grills in various sizes to match the window colour.
Grills can be manufacture in a variety of metallic and vinyl materials to match your existing windows and help you create a perfect custom style that suits your home, or your taste.
Because grills take up space inside an insulated glass unit, they reduce the amount of sun that warms your home. They also allow for less gas fill to be inserted into the sealed unit, thus making it more susceptible to heat loss than regular non-grilled windows. Unfortunately, this means grills will make your windowless energy efficient than the same window without grills.
One of the biggest post-installation problems associated with grills is that over time, they can fall out of place. Unfortunately, there is no easy fix for fallen window grills and the only way to resolve the problem is by replacing the entire sealed unit. If you are choosing grills as a window option, be sure to discuss the warranty and service procedures with your window consultant.
There’s a lot to think about when trying to match grills to already installed windows. Bayview carries several different window brands, each with their own grill sizes, styles, patterns, materials and colour options to maximize your window choices.
