Exterior Capstock Colour Options

At Window City we understand how important it is for homeowners to be able to choose exterior patio door colours for their home other than white. We also realize that durability is essential. We were one of the very few companies in North America who invested in the extruded Capstock colour technology from Europe as early as 1998. Our Capstock colour bonding system, co-extrudes a solid PVC colour onto our extrusions that bonds directly with the uPVC vinyl frame. We saw this as being a critical element in finish durability in our North America climates. The Capstock process ensures: Durability, Colour Retention, Stain and Scratch Resistance, Gloss Control and Impact Retention.

Patio Doors - Colours

We offer 18 exterior paint colour choices which are water based and environmentally friendly as well as weather and fade-resitant.

Window City’s Solar Solutions glass options provide several choices to maximize energy savings. Our products meet or exceed the Energy Star requirements in Canada.

We are constantly improving our insulating values, with our one of a kind system that allows us to certify the gas content in each and every unit, by applying our gas right at the time of sealing the unit. The non-conductive Super Spacer (S.S.) helps to keep the cold or hot from transferring to the interior, and reduces condensation build up in winter.

Super Spacer
Window City windows come standard with Super Spacer, the world’s only 100% polymer foam, NO-Metal Warm Edge spacing system. “Thermal efficiency through no presence of conductive metals” is Super Spacer’s hallmark. The edge of the insulating glass unit is indeed the most vulnerable to heat and cooling loss, condensation and frosting. Super Spacer’s NO-Metal formula blocks the heat escape path and provides one of the best thermal performances in the industry. That means it keeps the heat in during the winter months and keeps the cool in during the summer months. Super Spacer assures comfortable winter humidity levels with hardly any worries about condensation and mould.

When the weather turns frigid, LoE-180™ glass is the perfect cold remedy. It provides excellent insulating capability, blocking heat loss to the outside and reflecting heat back into the room plus it allows the winter sun’s heat to pass into the home. The dramatic improvement in comfort from windows with warm glass surfaces also means the relative humidity of the indoor air can be controlled and maintained properly. The better insulated the window glass, the warmer your room will be.
LoE-272 glass is ideal for all weather conditions in most climates. In winter, it reflects heat back into rooms. In summer, its patented coating blocks 86% of the sun’s harmful ultraviolet rays and 63% of the sun’s heat. During cold weather, the insulating effect of your windows has a direct impact on how your rooms feel. Typically, 75% of the exposed surface of a window is glass, and the temperature of the room-side of the glass directly affects the air temperature in the room. The better insulated the window glass, the warmer your room will be.
The new LoE-i89™ coating will be found on the inside surface (room side) where it reflects the escaping heat back into the room, lowering U-factors and meeting the toughest energy guidelines as well. Coupled with our LoE 180 and argon fill, this double pane unit delivers near triple pane performance. What’s more, LoE-i89™ enhanced performance glass is easy to clean and there is no haze to mar the view allowing more light to come into the room.

Neat® Naturally Clean Glass

Window City’s Neat® naturally clean glass harnesses the sun’s UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless. Your windows will stay cleaner longer and will clean easier.

Homeowners and builders will enjoy the effects that a little sun, rain and Neat glass brings to windows. In addition, because Neat is applied to Window City’s LoE-180™ coated glazings, homes stay cooler in the summer and warmer in the winter.

Argon Glass
At Window City our double-pane windows can be filled with argon gas to help insulate a room and minimize the transfer of heat through the window. Argon Gas is a colourless, odorless gas, that is denser than air thus adding it to the captive air in double-pane windows improves thermal insulation efficiency. Installing argon gas-filled windows can help improve your energy efficiency and lower your home energy costs.
Krypton Glass
Krypton gas is an inert, slow-moving gas that improves thermal performance. Denser than Argon, Krypton gas does an excellent job of preventing heat loss. For maximum efficiency, Krypton is usually used in triple pane windows.

Krypton/Argon Mix Gas
Why choose one? Window City introduces an optimal combination of Argon/Krypton Mix to increase the energy efficiency of your windows. This combined duo also significantly reduces outside sound, adding to the privacy of your home.
