Six Types of Replacement Window Glass

Window panes damaged by damage can result in energy loss and a rise in utility costs. Replacement of windows is a a simple fix to reduce the risk of these issues.

But when does it make sense to replace only the glass? This is typically less expensive than a full replacement and you can also keep your window frames.

Types

Replacement window glass is a complicated process that both general contractors and homeowners alike must take into consideration various factors. This includes energy efficiency, safety and aesthetics. Glass is available in a broad range of thicknesses, styles, and options for customization. This blog post explores six different types window glass to help you choose which one is suitable for your project.

Single Lite Glass

Single pane glass is a common sight in older homes and structures. While it offers clarity and is easy to clean, it doesn't have the enhanced insulating properties of the modern double-pane windows. It is also dangerous in the event of a break, as it can easily become pieces.

This kind of glass is typically required for historical replication since the glass must be a replica of the original design to preserve the original property. It isn't very energy efficient and must be replaced by a new, insulated window unit.

Double-paned Insulated Glass

This is a popular choice for homeowners who are more modern. It is comprised of two panes tempered glass separated by an air-filled spacer. This kind of glass can be more efficient in energy use than a single pane window and can reduce the transmission of noise and condensate.

Triple Pane Insulated Glazing

This is an upgrade from double-paned glass with insulated coating. It features three panes glass that are tempered and an argon gas or Krypton fill between them to provide an increased level of energy efficiency. The gases can help reduce energy costs by trapping heat in the winter months and letting it out in summer.

The other two choices are decorative and enhance the look of your exterior of your home. Laminated or tempered glass is more durable than normal glass, which makes it an ideal choice for areas susceptible to being damaged by debris or weather conditions. For added privacy tinted or glazed glasses can be used instead of traditional glass. It comes in a variety of colors and can be frosted, etched or patterned to enhance a window's appearance.

Thickness

Glass thickness is a crucial factor to consider when buying new windows or replacing old glass panes. No matter if it's single strength or double strength, laminated or insulated glass, the thickness of the glass will affect several aspects including security, energy efficiency and noise reduction. Local construction codes and manufacturer specifications are essential to be aware of.

The most basic kind of window glass is single strength - which is a basic piece of clear glass. The glass is 3/8 inch thick and is commonly used in residential applications. If you live in a high-rise, or your home is near an airport, your windows may require double strength window glass.

Double-strength glasses are made by fusion of two or more sheets of glass with PVB (polyvinyl butyral). The fusion process uses high temperatures and pressure to create a durable, strong pane of window glass that is five times stronger than normal glass. This kind of glass is recommended if you want your windows to withstand damage by flying debris, such as rocks or balls.

Laminated glass resembles double-strength glass, but it comes with additional benefits such as noise reduction and safety. It is created by fusing at a minimum two sheets of clear glass together with interlocking resin or plastic to form a strong, layered panel that is hard to break. This kind of glass is suggested for those who are concerned about protecting your children or pets from accidental falls, and reduce the noise levels within your home.

Insulated glass can be made by adding spacers to the glass. This creates an airspace that can then be filled with different gasses that are insulating to improve the window's performance. This will reduce the amount of air that enters or leaves the home. Glass is available in a wide range of shapes and sizes.

You can tint the glass to add a touch of elegance or to enhance privacy. It is important to remember that tinting can void any warranty. The turnaround time for insulated replacement glass may vary from 7-10 days based on the size and customization.

Customization

Depending on your goals for replacement windows, you may want to upgrade the glass to increase the efficiency of your home's energy use and privacy. You can pick from options like Low-E coating and insulated glass thickness and the amount of air space between panes.

Energy-efficient glass can reduce your energy consumption by reducing the transfer of heat from the indoors and outside. Some of these glass options can also reduce noise, offer UV-ray shielding, and improve durability. You can also pick tinted glass to add a splash of color or frosted glass for more subtle appearance.

Decorative glass is purely aesthetic and has no practical uses, but it can be a great option to make your home unique. You can choose between a variety of styles and finishes to create an appearance that matches your personality. You can even have a door or window with a customized shape.

Choose between double-paned, single-paned, or triple-paned windows with different amounts of airspace between the panes. The more airspace the window has, the better it is more insulated.

Your contractor can provide an in-depth description of the kinds of glass available and their costs. They will also be able to recommend the most suitable glass for your needs. You can ask them to upgrade your windows with more energy-efficient glass.

Many modern replacement windows include gas spacers with warm edges that insulates the area where the frame meets with the glass, and also a layer of that is filled with argon. These features keep the window warmer in the winter months and cooler in summer.

While it's common to choose a clear, standard glass, you can select patterns, frosted, or tinted windows. This can give a unique appearance and may also provide privacy. However, it's important to think about the impact on your home's style and lighting. There are also special windows with features that enhance security and ease of operation including spring tensioners to avoid the windows from crashing and sensors to identify potential damage.

Installation

If you're looking to replace the glass in just one window panes replacement, or all of them, the procedure is quite simple. First professionals will prepare the opening by removing the old putty and then scraping the grooves clean. They will also drill holes of 3/8-inch diameter one at each end and a single hole in the middle along the sill and then up through the head jamb. They will then inject expanding foam in the pockets of sash weights to fill air gaps. In the end, they will apply an elastomeric caulk along the frame's outer edges to shield against moisture and seal the gaps between the glass.

Before beginning the replacement process, take measurements of the windows' openings making sure to take into account the thickness and width of the frame. Also subtract 1/8 inch from the width and height measurements in order to allow the expansion and contraction of the frame as weather conditions change. If you do not subtract this amount, the new glass may be damaged during the installation process.

Once you have the measurements, contact your glass manufacturer and place an order for the exact dimensions of the replacement windows. After your initial call you should receive your windows within a few weeks. They will be ready for installation within one week. Before beginning the removal process, you must take off any blinds or curtains that are near your windows. Also, make sure that you have a clean work area. You should also put a piece of plastic or cloth down on the floor to hold any broken glass that could fall.

Utilize a paint scraper to remove any wood moldings that are attached to your frame. If there are any metal glazing points you can use a heat gun to soften them prior trying to remove them. After the old window has been removed and discarded, use a hammer or paint scraper to clean the grooves in which it was originally installed. Re-caulk with an elastomeric sealant to match the new windows.
