Bay Windows

Thompson Creek’s® vinyl bay windows are the perfect choice for creating curb appeal while adding light and warmth to your home’s interior.

Our exterior bay windows are typically comprised of one center picture window that allows light to flood into your home. This center window is usually flanked by your choice of casement or double-hung windows on each side. Every bay window is made with the highest quality materials and our most energy-efficient glass for maximum durability, comfort and cost savings.

double glass pane

Doublepane-glass - These windows feature two panes of standard low thermal emissivity, or Low-E, glass, separated by a spacer. The pocket between the two layers of glass is filled with argon gas and sealed. Argon gas is a inert gas that is non-toxic, colorless, and odorless gas that is heavier than air and displaces the air between the glass panes, acting as an insulator. All Thompson Creek windows start with the double pane glass package by default.

triple pane glass
Triple pane windows

Triple pane windows - Triple Pane windows feature all the benefits of Double Pane windows with an added layer of thermal protection. An extra air pocket helps buffer temperature extremes. Three panes of Low-E glass add strength, energy efficiency, and durability. These windows are heavier than Double Pane windows, but offer more energy cost savings over time. The triple pane glass package is only available in our 7900 series premium windows.

Sound shield windows

Sound shield windows - Sound Shield is our proprietary noise abatement glass that filters out up to 35% more outside noise than our double pane glass package. We recommend Sound Shield for homes in loud areas with highway traffic, airports, trains or other outside disturbances. Sound Shield is available in awning, casement, picture windows, and our 7900 series premium double-hung and picture windows.

Obscure Glass

Obscure Glass - Available with double pane and triple pane glass packages. Obscure glass or “privacy glass” has a pattern embedded into its surface, making it difficult for to see through. Recommended uses: private offices, bathroom windows, private rooms.

Tempered Glass

Tempered Glass - Available with double pane, triple pane and Sound Shield glass packages. Tempered glass is 4-5 times stronger than conventional window glass. Tempered glass undergoes compression during its formation, meaning that it’s more break resistant. If it does break, it will break into smaller, less jagged pieces for your safety. Recommended uses: bathrooms, and windows less than 60 inches off the ground.


Half - Half-screens let in more light through the uncovered pane, allowing you to open one sash of your window while giving you a pristine view through the other half.


Full - Full-screens provide complete coverage for your window. This option allows you to partially open both sashes to better circulate air through your home, all while keeping bugs and leaves out.

trimmodern-200x200 C

Modern - Trim helps define the style of your window while covering the seam between your window and the wall where it is installed. Our Modern-style trim offers clean lines and stark, 90 degree angles.

trimcolonial-200x203 C

Colonial - Trim helps define the style of your window while covering the seam between your window and the wall where it is installed. Our Colonial-style trim offers stately curves redolent of classic woodworking.

Grid_Flat-200x115 C

Flat - Our flat grids offer a sleek, contemporary take on the simulated divided-lite grid. Flat grids are installed between the glass layers, partitioning the window while allowing for easy cleaning.

Grid_Contoured-200x115 C

Contoured - Our contoured grids give a sense of classical elegance with their stately curves and colonial feel. Contour grids are installed between the glass layers, partitioning the window while allowing for easy cleaning.

A combination of three windows joined at an angle, a true replacement bay window extends out beyond your walls to add space to your room. A replacement bay window also has a type of roof attached above and a seat board below.

A replacement bay window is custom-built to fit within the opening of an existing window. It is built to fit precisely and can be installed without disturbing the interior and exterior areas around the window. Since custom windows are made to fit precisely, they are the most energy efficient.

In most cases, our factory-trained crews can replace a bay window in one day.

We recommend partnering with a window company that manufactures their own energy efficient bay windows, has a proven reputation for quality products and customer service, and provides a comprehensive warranty on every product they sell – including installation and labor.

It also makes sense to work with a company that manufactures their bay windows  locally, which saves a significant amount on shipping charges. At Thompson Creek, we are accountable for the entire process from window design through installation. Additionally, we participate in the National Fenestration Rating Council (NFRC) certification and labeling process, as well as the ENERGY STAR® program.

There is no set rate to determine the cost of your new bay windows, without inspecting the property and installation requirements.. We recommend requesting a free no obligation quote, which includes a consultation with one of our experts. At the end of that consultation, you will receive a written proposal with the finished price and any available financing options.

Low-emissivity, or low-e glass, is a very thin coat of material that reflects heat away from the window’s surface, keeping heat out in the summer and inside in the winter. Low-e glass is the most cost-effective way to increase the efficiency of your windows. It can also help reduce the amount of ultraviolet radiation entering your home, reducing discoloration or fading to your furniture and carpet.

ENERGY STAR® is an independent U.S. government program that establishes a set of guidelines to recognize the energy efficiency of various products. ENERGY STAR® guidelines are used for a variety of building materials including windows and doors. Over the past 10 years, ENERGY STAR® guidelines have helped double the efficiency of the windows they endorse.

The American Architectural Manufacturers Association (AAMA) sets all performance standards, product certification and educational programs for the window industry. When a product passes AAMA tests, it guarantees reliable performance if properly installed.

The National Fenestration Rating Council (NFRC) is a non-profit organization created by the Department of Energy and the window and door industry. The NFRC provides energy performance ratings on windows and doors. The NFRC label on a window or door informs consumers about a product’s U-factor, which takes into account a product’s ability to block warming caused by sunlight, light transmittance and air leakage through cracks in the product’s assembly.

This depends on various factors, such as how many windows you currently have, the windows’ age and condition, wall and attic insulation, as well as how you use other items in your home that use energy. Thompson Creek windows exceed ENERGY STAR® standards and can help lower heating and cooling bills.

Almost without exception, new windows, siding, doors and gutters will add significant value to your property. First, when it’s time to sell your home, the new buyer will negotiate your asking price downward when they factor in the cost of windows, siding or gutters that will need to be repaired or replaced. Second, studies show that the two most important items on a new homebuyer’s list are energy efficiency and less exterior maintenance. According to Remodeling Magazine’s  Cost vs. Value Report, a homeowner can recoup a significant portion of the cost of a typical window replacement project.
