Glass Package Options
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 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 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 – 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 – 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.
(Optional) Trim Types
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.
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.
(Optional) Grid Types
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.
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.
SDL – Windows used to be made of multiple small panes of glass. A simulated divided-lite (SDL) grid emulates a traditional divided window, with grid elements on the interior and exterior glass.
Speciality Grid Patterns
A colonial grid pattern is probably what you think of when you imagine a classic window grid. Both the top and bottom half of the window are divided into six equal rectangles, making for a classic and versatile look that fits many styles. You can also consider going half-colonial, where the bottom half of the window is left undivided by grilles.
Colors
Custom – We can match most colors in the Sherwin Williams catalog.
