Your windows may offer a lovely view, but they could also be the most vulnerable part of your home when it comes to energy loss—especially in a Red Deer winter. According to Natural Resources Canada, windows, doors and skylights can account for up to 35% of total heat loss in a typical home. In older houses or those with outdated or poorly installed windows, that figure can be even higher. At Oriel Windows and Doors, we work with homeowners to stop that unnecessary heat loss in its tracks.

Fix heat loss through window with a winter upgrade from Oriel in Red Deer

What causes heat to escape through your windows? It’s often a combination of factors. Single-pane glass has minimal insulating value, and even older double-pane windows can lose effectiveness over time. If seals fail, or if the frames have warped due to years of seasonal expansion and contraction, cold air finds its way in and warm air slips out. Moisture between panes, draughts near the sill, and condensation in winter are all telltale signs that your windows are no longer doing their job.

At Oriel Windows and Doors, we conduct thorough assessments of existing windows to determine how much heat is being lost—and where. We look at frame condition, pane performance, air infiltration and insulation around the window opening itself. Then we help you choose the right energy-efficient window upgrades to match your home's needs and your style preferences.

Modern energy-efficient windows do much more than reduce draughts. They come with features like inert gas fills between panes, Low-E coatings that reflect heat back into your home, and multi-chambered frames that resist thermal bridging. Together, these enhancements dramatically improve your home’s insulation value, keeping more heat inside where it belongs. And with Alberta’s energy costs, that matters. In fact, many Red Deer homeowners who switch to triple-pane windows see energy savings within the first year.

But no window can perform as intended without quality installation. That’s why our team ensures that every installation includes airtight sealing, properly installed flashing, and careful attention to thermal breaks at the frame level. We’re not just selling a product—we’re delivering a full building envelope solution that meets the demands of Alberta’s harsh climate.

If you're tired of putting up plastic film, dealing with chilly breezes or watching your heating bills climb, it’s time to act. Schedule a consultation with our team today. We’ll inspect your current setup, provide recommendations, and prepare a free quote. Better yet, upgrading your windows can also enhance curb appeal, reduce noise and increase your home's resale value.
