Six Types of Replacement Window Glass

Damaged window panes can cause energy loss and a rise in utility costs. Replacement of windows is a an easy fix to lessen these issues.

But when does it make sense to replace only the glass? This option is often cheaper than a full replacement and you can retain the window frames.

Types

Replacement window glass is a complicated process that homeowners and general contractors alike must take into consideration many factors. This includes energy efficiency and protection. Glass comes in a variety of designs, thicknesses and options. In this blog post, we look at six different kinds of window glass to help you determine which one is the best fit for your project.

Single Lite Glass

Single pane glass is a common sight in older homes and buildings. It is easy to clean and provides clarity, but it does not provide the same level of insulation as modern double-paned windows. It is also dangerous if it breaks, as it can easily turn into pieces.

This kind of glass can be used for historical replications, where the glass must be in line with the style of the original property in order to keep it in good condition. It is not energy efficient and should be replaced with a new insulated window unit.

Double Pane Insulated Glass

A very popular choice for modern homeowners, this type of window consists of two panes of glass that are tempered and separated by a spacer that is filled with air for insulation. This kind of glass could be more energy efficient than a single-pane window and can reduce condensate and noise transmission.

Triple Pane Insulated Glazing

A step above a double-pane glass that is insulated, this option has three panes of tempered glass that have an gas filled with argon or Krypton between the panes to create an even greater efficiency in energy usage. The gases hold heat in winter and keep it out in summer, helping to further cut energy costs.

The last two options are decorative and can enhance the look of your home's exterior. Laminated glass or tempered glass is more durable than regular glass and can be used in areas that may be damaged by debris or weather conditions. Glass that is tinted or glazed can be often used in place of traditional glass for added privacy. It comes in a range of colors and can be frosted, etched, or patterned to enhance a window's appearance.

Thickness

Glass thickness is an important factor to consider when buying new windows or replacing old glass panes. The thickness of the glass, regardless of whether it is laminated or double strength, insulated, or single strength double strength, will impact a number characteristics that include security and energy efficiency as well as sound reduction. Local requirements for building codes and manufacturer requirements are important to keep in mind.

The most basic type of window replacements glass is single strength, which is a simple sheet of clear glass. The glass is 3/16" thick and is utilized in a majority of residential applications. If you live in a high-rise building or live near an airport, your windows may require double strength window glass.

Double-strength window glass is made by fusion of at least two sheets of glass together with PVB or polyvinylbutyral. The fusion process uses high heat and pressure to produce a tough, durable piece of window glass that is five times more durable than normal glass. This kind of glass is recommended for those who want to shield your windows from flying debris, like balls or rocks.

Laminated glass is similar to double-strength but has additional perks such as noise reduction and safety. This glass is made by fusing at a minimum two sheets of clear glass with layers of interlocking resin or plastic to form a strong layer that is difficult to break. This type of glass is suggested if your primary concerns are protecting your children or pets from accidental falls, as well as reducing the noise level within your home.

Insulated glass is made by putting spacers between the glass to create an air space which can be filled with a variety of insulation gases to improve window performance. This can reduce the amount air that is able to enter or leave the home. This glass is available in various sizes and shapes, ranging from square or rectangular to arched or circular.

The insulated glass can be tinted to provide an element of privacy or style. It is important to remember that tinting will invalidate any warranty. The time frame for insulated replacement glass may vary between 7 and 10 days, based on the size and customization.

Customization

You can upgrade the glass in your new replacement windows to increase your home's privacy and energy efficiency. You can choose from options such as Low-E coating, insulated glass thickness, and the amount of air space between panes.

Energy-efficient glass can cut down your energy costs by cutting down on the transfer of heat between indoors and outdoors. Some of these options can also reduce noise, offer UV protection, and increase durability. You can also opt for tinted glass to add a pop of color or frosted glass to give a more subdued look.

The purpose of decorative glass is to enhance the aesthetics and doesn't have any practical uses, but it can be a great option to make your home more unique. You can pick from a variety of patterns and finishes to create a style that matches your personal style. You can have a window or door with a custom-designed shape.

Choose from single-paned, double-paned, or triple-paned windows with different amounts of airspace in between the panes. The more airspace your window has, the better it will be well-insulated.

Your contractor will provide you with an in-depth description of the glass types and costs. They can also suggest the best type of glass for your requirements. You can also ask them to upgrade your old windows with more energy efficient glass.

Modern replacement windows come with a warm-edge spacer that protect the area where the frame meets the glass and a layer of argon gas to fill the gaps between the panes. These features allow windows to remain warmer in winter, and cooler in summer.

You can pick from frosted, patterned or tinted glass. This type of window has a distinctive design and provides additional privacy. However, it is important to take into consideration the impact on your home's style and lighting. There are also specialty windows that have features that improve security and ease of operation like spring tensioners to prevent the windows from crashing and sensors to identify potential damage.

Installation

Whether you want to replace the glass in just one window, or all of them, the process is fairly straightforward. A professional will first prepare the opening, removing the old putty. They will then scrape the grooves to remove any dirt. They will also drill three holes of 3/8 inch in diameter one at each of the ends, and a single in the middle, through the sill and up through the headjamb. They will then inject expanding foam in the pockets of the sash to fill in air gaps. Then, they'll apply an elastomeric sealant along the exterior edges of the frame, to protect it from moisture and close any gaps around the new glass.

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

Contact your glass manufacturer to place an order with the exact dimensions for your replacement windows. You should receive them within a few days of the initial phone call and they'll be ready for installation in about a week. Before beginning the removal process, remove the blinds or curtains close to your windows. Also, make sure that your workspace is clean. You should also place a piece of cloth or plastic on the floor to stop any broken glass that may fall.

When you're ready to begin removing the old window pane, start by using a paint scraper or an old chisel to take away any pieces of wood molding connected to the frame. Warm the glazing points of the frame before you attempt to pull them out. After removing the old window using a hammer or paint scraper to clean the grooves in which it was initially installed. Re-caulk the area with an elastomeric sealant that is compatible with the windows that are replaced.
