When You Need an Egress Window in Your Basement

Building codes in most regions require at least one egress window in any basement used as a bedroom or finished living space. That means if you’re planning on converting your basement into a guest room, family area, home office, or rental suite, an egress window is essential for both safety and compliance.

Exceptions:

Basements used only for storage or mechanical systems under ~200 sq ft may not require egress windows.

Delco brings you the best in high efficiency window technology through a full line of glass options by Pilkington, Guardian & Cardinal Glass.

	LOE-180 by Cardinal or LE8 by Pilkington This is our standard glass package for all windows. Specially designed for Toronto’s climate, LoE-180 keeps your home warm on the inside, when it is freezing on the outside. It allows more of winter’s sunlight to pass through into the home, creating passive solar heating, while blocking heat loss during the night. By using a unique coating on the outside of the window, Cardinal’s LoE-180 windows creates a thermal barrier that help make your home fully insulated, while having plenty of natural light. This is the highest base standard glass for Canadian climates throughout Toronto, the GTA, and Ontario areas. It raises the bar and creates the new EnergyStar standard for all of Canada. Delco is proud to have LoE-180 as its standard glass package for new window installations. This window technology will help make your home a cozy, warm and comfortable home year round.
	LOE-272 Year-round comfort for your home. Cardinal’s LoE-272 window glass helps your home to be warm and cozy in the winter, and cool and comfortable in the heat of the summer. It offers that right balance needed for your home. While Toronto’s winters can be cold, summer days can be downright uncomfortable. Windows themselves can transmit temperature to the touch, causing energy loss. LoE-272 nearly eliminates this problem. In winter, LoE-272 reflects heat back in the room. In summer, it reduces heat gain from the window by preventing heat absorption of the window itself. Saving you on your summer air conditioning costs, while reducing winter heating costs. This give the opportunity to have all-year energy savings at its highest level.
	LOE-366 by Cardinal or LE6 by Guardian THE NEW OUTSTANDING WINDOW GLASS for ultra high-efficiency homes. LoE-366 delivers the ideal balance of solar control and high visibility. And it provides the highest levels of year-round comfort and energy savings, making it the perfect glass for homes in the Toronto area. What makes that happen? A unique technology using a triple layer of silver. The coating is clear, yet blocks even more summer solar gain, yet reflects winter heat back into your home. Bright, well lit, and comfortable . . . all year long. Also, LoE-366 offers the highest in fading protection. It blocks 95% of the sun’s damaging UV rays, a major cause of furniture, curtains, paint and floor fading. LoE-366 not only protects your energy bills, but extends the life of your home’s cherished items. Lastly, by reducing temperature differences on the glass, it reduces humidity buildup. The benefits are endless! If you want to let light in, while avoiding the negative effects of tinting, LoE-366 is for you. Ideal for modern homes, off-grid, or homes seeking to be near zero-emissions. This is the ultimate standard in energy efficient windows for homes around Toronto. And Delco is happy to offer this upgrade to any window installation package.
	LOE-i89 Cardinal’s LoE-i89 gives the best U-factors (insulating property) of all its glass packages. Delco offers LoE-i89 as an upgrade to any of its standard glass packages. What sets this glass apart is its enhanced winter performance for northern latitudes like much of Canada. It allows even more natural light in, while reducing heat loss than our standard glass package. It reflects your interior heat back into your home. It’s like having triple pane window power inside a simple double-pane window. And to top it off, there is no haze to worry about. Clean, transparent windows, that bring the warm winter sun into your home, and helps you enjoy all the views, right from the comfort of inside your home. You’ll have the warmest, most comfortable home in the neighborhood with windows using LoE-i89 technology.
	Triple Glass Triple-pane glass gives you the highest energy efficiency through multiple layers of insulation in your window panes. Three Panes, separated by your choice of gas-filled or standard spaces. More deluxe than double-pane windows, triple-pane gives you a superior insulation factor. This provides the ultimate in high-efficiency window technology.
	Neat® With the Neat® glass option, you gain natural cleaning convenience. By harnessing the sun’s UV rays (even when the sky is cloudy) to loosen dirt from the glass, rainwater can easily rinse away grime. Living in Canada, you know how dirt, rain and snow can be hard on windows. Why not let nature clean your windows?
	Preserve Preserve® film is standard, and factory-applied to both the interior and exterior surfaces of the glass of many of our windows. This means the glass surfaces will be protected from dirt and scratches that could occur during shipping and handling or at a construction site of your home. No need to spend extra time cleaning your new windows. With easy quick removal, your windows will be spotless from day one.
	Laminated Glass Have the ultimate in protection from window breakage with Laminated Glass. By building in an interior transparent plastic vinyl layer, broken shards of glass will stay adhered to it and reduce the problem of glass pieces. It also strengthens the window itself. Laminated glass is offered as an upgrade to many of Delco’s window installation packages.
	Tempered Glass The tempered glass option is available in all glass types and provides extra strength, enabling it to withstand force or pressure on its surface and it will not break into sharp pieces and glass splinters. If ever broken, the glass will split in a safer way. Many local building codes in and around the GTA often encourage or require tempered glass to be used in all windows that are close to the floor or near doors, tubs, or showers.
