Fixed window standard sizes: The Benefits of Standardization

Windows are an essential part of any building, from residential homes to commercial edifices. They let in natural light and fresh air, they offer views of the outside world, and they add aesthetic value to the building's exterior and interior. Windows come in a variety of styles, shapes, and sizes, depending on factors such as architectural design, structural requirements, and functional needs. However, for many windows, standardization of sizes is a practical and cost-effective solution. In this article, we'll explore the benefits of Fixed window standard sizes, their various options, and how they can enhance your building projects.

What are Fixed window standard sizes?

Fixed window standard sizes are pre-determined measurements and configurations that manufacturers use to produce windows en masse. These sizes refer to the width and height of the glass and frame, as well as the thickness of the window pane, the shape of the sash, and the placement of mullions (dividing bars between panes). Fixed windows, also known as picture windows, do not open and close, so they do not require additional hardware or mechanisms like hinges, handles, or locks. Therefore, Fixed window standard sizes are often more straightforward and consistent than those of operable windows, such as casement, double-hung, or sliding windows, which have more moving parts and different modes of operation.

Benefits of Fixed window standard sizes

1. Cost-Efficiency

Using Fixed window standard sizes can save you money in several ways. First, standard sizes are often less expensive than custom sizes because they require less labor, equipment, and materials to manufacture. Second, standard sizes are widely available, which means they're easier to order, stock, and transport, reducing delivery times and shipping costs. Third, standard sizes can simplify the estimation, budgeting, and bidding process for construction projects, as contractors can easily compare prices and specifications from different suppliers and make informed decisions.

2. Time-Saving

Fixed window standard sizes can also help you save time in the building process. As mentioned earlier, standard sizes are more readily available than custom sizes, which means they can be delivered faster and installed quicker. This can be especially helpful for projects with tight deadlines or large volumes of windows. In addition, since fixed windows do not need to be opened or closed, they don't require any specialized installation techniques or adjustments, which can simplify the installation process.

3. Design Flexibility

Although Fixed window standard sizes have pre-set dimensions, they still offer design flexibility in terms of shape, style, and appearance. Many manufacturers offer fixed windows in various shapes, such as rectangles, squares, circles, or arches, depending on the desired architectural design or aesthetic preference. The frames can also be customized with different profiles, colors, or finishes, such as wood, vinyl, aluminum, or fibreglass, to complement the building's exterior or interior style. Mullions and grilles can also be added to mimic the look of divided light windows, adding a touch of elegance or tradition.
