Windows & Doors TerminologyGlass Efficiency Options


ENERGY STAR-qualified windows, doors, and skylights save you energy and money, increase the comfort of your home, and protect your valuable possessions from sun damage. They are also better for the environment because lowering your energy use means less air pollution from power plants.

Argon Gas

Argon is a colourless, odourless, non-flammable, non-reactive, inert gas. Argon gas fills are used to reduce heat loss in sealed units by slowing down convection in the air space. Argon gas is very cost efficient, and works in unison with Low E coated glazing. Argon is the most commonly used fill gas, due to its excellent thermal performance and cost-efficiency in comparison to other gas fills. By replacing the air between the panes of a window with Argon gas, thermal performance is improved. Argon gas helps prevent convective heat loss (cold air moving through the window) as well as conductive heat loss (cold air being radiated from the window) to improve energy efficiency.

Bronze & Gray Tint

The primary purpose of the bronze or gray tint is to reduce solar heat gain, but, it also reduces visible light transmission compared to Double-Glazed with Clear Glass or even other standard tinted glass products such as green and blue tints,all of which offer significantly higher visible light transmission. Bronze glass cuts down on the amount of glare and heat entering a building. The bronze coloration makes an especially dramatic statement for a glass facade and has become increasingly popular.

Krypton Gas

Krypton Gas, an inert, odorless, colorless, tasteless, nontoxic gas which is about 12 times denser than air. It is used to replace air between the glass panes to reduce heat transfer and deter convection. Used when a higher performance is desired than that produced with Argon gas.

Low-E Glass

Low-E glass is manufactured by depositing a microscopically thin, transparent metal or metallic oxide layer on the glass. Low-E coatings reduce radiant heat loss, and can reduce the passage of UV rays.

Quad-Seal Windows

Quad-Seal windows offer a supreme level of energy efficiency. Quad-Seal windows are equiped with four seals to dramatically reduce drafts, air leakage and heat/ cold loss.

Additional Glass Options:

Obscure Glass

When you need your privacy but you also want the sunlight, Northview Window's obscure glass will provide an effective shield without shutting out the sun. Obscure glass, available in pebbled or glue chip pattern, is particularly useful for bathrooms, basements or along walkways.

Tempered Glass

Tempered glass is one of two kinds of safety glass regularly used in applications in which standard glass could pose a potential danger. Tempered glass is four to five times stronger than standard glass and does not break intosharp shards when it fails. Manufactured through a process of extreme heating and rapid cooling, making it harder than normal glass and the go-to option when safety issues are front-and-centre. The added strength of tempered glass means it can withstand blows that would shatter other glass. And there’s less chance of injury if it breaks because fragments are smaller.

Thermal Edge Spacer

The Thermal Edge spacer features a steel core with a polymer bridge that enhances thermal performance. Steel is less conductive than aluminum, and creates a vapor barrier and offers increased structural integrity. The glass edge touches the polymer and not the steel, thus creating a "warmedge" which will reduce condensation and raise the temperature of the "edge of glass" area in your sealed unit.

Designer Grills

We offer a selection of Colonial, Pencil and Georgian grills, all of which area available in your choice of white, gold, or pewter.

Triple-glazed windows

Triple-glazed windows offer incredible energy efficiency. Triple-glazed windows utilize three panes of glass to dramatically reduce condensation and thermal transfer while insulating as much as 60% better than double-glazed windows.
