Six Types of Replacement Window Glass

A damaged window pane can be an issue that could cause lower energy usage and higher energy bills. Window glass replacement is an easy solution to eliminate these issues.

When is it a good idea to replace just the glass? This is typically less expensive than a complete replacement and you can retain your window frames.

Types

Replacement window glass is a complex process that general contractors and homeowners alike must consider numerous aspects. This includes energy efficiency, protection and aesthetics. Glass is available in a variety of styles, thicknesses, and customization options. In this blog post, we explore six different kinds of window glass to help determine which one may be the best choice for your project.

Single Light Glass

Single pane glass is a common sight in older homes and buildings. It is easy to clean and offers clarity however it doesn't provide the same insulation like modern double-paned windows. It can also be dangerous in the event of a break because it is prone to becoming fragments.

This type of glass is usually required for historical replication, as the glass must be a replica of the original design in order to preserve the original design. However, it is not very efficient and should be replaced with a brand new, insulated window unit.

Double Pane Insulated Glass

A favorite option for modern-day homeowners, this design consists of two panes of glass that are tempered and separated by a spacer which is filled with air for insulation. This type of glass is more efficient in energy use than a single pane window, and it can also reduce condensation and noise transmission.

Triple Pane Insulated Glass

A step up from a double-pane glass that is insulated, this option has three panes of tempered glass, each with an argon gas or krypton gas fill between the panes to create an even higher efficiency in energy usage. The gases help to reduce energy costs by trapping heat in the winter months and keeping it out in summer.

The other two options are decorative and can enhance the look of your exterior of your home. Laminated or tempered glass is stronger than regular glass, making it a great choice for areas susceptible to damage from debris or weather conditions. Glass that is tinted or glazed is often used in lieu of traditional glass to provide privacy. It is available in a variety of colors and can be frosted, etched, or patterned to enhance a window's appearance.

Thickness

Glass thickness is among the most important factors to take into consideration when buying new windows or replacing existing glass panes. The thickness of the glass, regardless of whether it is laminated, insulated, single strength or double strength, will affect several aspects such as security and energy efficiency as well as noise reduction. It is also crucial to think about local building codes and the requirements of the manufacturer.

The most basic type of window glass is single strength, which is a basic piece of clear glass. The glass is 3/8 inch thick and used in residential applications. Double strength window glass might be required for those who reside in an airport or a high-rise building.

Double-strength window glass is produced by fusing at least two sheets of glass together with PVB or polyvinylbutyral. The fusion process utilizes extreme pressure and heat to create a strong, durable pane of glass that is around five times stronger than normal window glass. This kind of glass should be used if you wish to protect your windows from flying debris, like balls or rocks.

Laminated glass has numerous advantages over double-strength glasses, including noise reduction and security. This glass is made by fusing at least two sheets of clear glass with interlocking resin or plastic to form a strong and layered panel that is difficult to break. This kind of glass is recommended if your primary concerns are protecting your pets or children from accidental falls, as well as lessening the noise within your home.

Insulated glass can be produced by adding spacers to the glass. This creates an air space which can then be filled with different gasses that are insulating to improve the window performance. This will reduce the amount of air that escapes or enters your home, which improves the energy efficiency. Glass is available in a variety of shapes and sizes.

You can tint the insulated glass to give it a touch of class or to enhance privacy. It is important to note that tinting will void any warranty. The time frame for insulated replacement glass could vary from 7-10 days based on the size and personalization.

Customization

Based on the goals you have for new replacement windows, you may want to upgrade the glass to enhance the efficiency of your home's energy use and privacy. You can select from options such as Low-E coating and thickness of insulated glass and the amount of air space between panes.

Energy-efficient glass can cut down your energy costs by reducing the transfer of heat between indoors and the outdoors. Certain types of glass can also reduce noise, provide UV-ray protection, and improve durability. You can pick tinted or frosted glasses to add some color.

Decorative glass has no functional use and is only for aesthetic reasons. However, it can give your home a unique look. You can pick from various designs and finishes to create an appearance that matches your style. You can even create a door or window with a customized shape.

Choose between single-paned, double-paned triple-paned, or single-paned windows. Each has different amounts of airspace between the panes. The more airspace you can have the more insulation your window will be.

Your contractor can give you an in-depth description of the glass types and costs. They can also suggest the best glass for your requirements. You can also ask them whether they are able to upgrade your old windows to more energy efficient glass.

Modern replacement windows often have gas spacers with warm edges that protects the area where the frame meets with the glass, and also a layer of that is filled with argon. These features allow windows to stay warmer in winter and cooler in summer.

You can choose from tinted, frosted or patterned glass. This can give a unique appearance and can offer additional privacy. However, it's important to consider the impact on your home's style and lighting. There are also special windows with features that enhance security and ease of operation like spring tensioners to prevent collisions and sensors to detect the possibility of damage.

Installation

Whether you want to replace the glass in just one window, or all of them, the procedure is pretty simple. A professional will first prepare the opening by removing the old putty. They will then scrape the grooves in order to remove any dirt. They will also drill three holes of 3/8-inch in diameter one at each of the ends and one in the middle, through the sill and up through the headjamb. Then, they inject expanding foam into the sash-weight pockets to fill any air gaps. In the end, they will apply a layer of caulk made of elastomeric around the frame's edges to protect against moisture and fill in the gaps between the glass.

Take measurements of your window openings prior to when you begin the replacement window seals process. Be sure to include the thickness and width. Subtract 1/8 inch both from the width and height measurements to allow for the frame to expand and contract according to the weather. If you don't subtract this amount the new glass could be damaged during the installation process.

Call your glass manufacturer to place an order, indicating the exact dimensions of your replacement windows. After the initial call, you should receive the windows within a few weeks. They will be ready to install within about a week. Before you begin the removal process, clean out any curtains or blinds from the windows in front of them and make sure that you have a clear area to work from. Also, you should place a piece of cloth or plastic on the floor to hold any broken glass that could fall.

When you're ready to begin removal of the old window, start with a paint scraper or old chisel, to remove any pieces of wood molding connected to the frame. If there are any metal glazing points, use a heat gun to soften them before attempting to pry them off. After the old window is removed, use the paint scraper or hammer to clean the grooves in which it was previously installed. Re-caulk with an elastomeric sealant that matches the replacement windows.
