Designing Replacement Windows: What Makes a Window Energy Efficient

Designing Replacement Windows: What Makes a Window Energy Efficient

When you’re planning your project for replacement windows in Kelowna, energy efficiency should be number one on your priority list. That’s since inefficient windows can be responsible for the biggest heating and cooling loss in your residence.

They can lose as much as 30% of your heating and cooling, according to the U.S. Department of Energy. So, it’s important that your replacement windows are the wisest solution for the climate in Kelowna.

In choosing your new windows, here are a few points to keep in mind.

Window Panes: One, Two or Three?

Window panes are one of the most essential parts of an energy-efficient window. We advise choosing at minimum double-pane windows, since single-pane windows are especially inefficient. They’re also prone to seeping air and affecting your home’s comfort.

If your budget allows it, switching to ENERGY STAR® windows will help lower heating and cooling expenses and save you more money in the future. That’s because they work hard to keep your residence’s temperature in balance, despite the climate outside.

On average, ENERGY STAR says normal residences that get these windows can save*:

  • $101–$583 yearly when replacing single-pane windows.
  • $27–$197 annually when replacing double-pane, clear glass windows.

Over the life cycle of your windows, those savings can really add up. And you can also feel good being aware you’re helping reduce greenhouse gas emissions, which helps shield the environment.

Energy efficiency matters to us at Pella. That’s why we’ve associated ourselves with ENERGY STAR since 1999 and offer windows that meet or exceed certification in all 50 states. Windows from our Architect Series®, Lifestyle Series, 350 Series and 250 Series made the ENERGY STAR Most Efficient 2020 list. This means they’re among the most efficient that you can install.

Individualize Your Windows with Glass Options

Using special coatings and gas between window panes can keep your home cozier while blocking more ultraviolet rays. Wherever you reside, Pella offers an InsulShield® glass option that will fit your specific climate.

Choosing the Ideal Window Frame Material

When designing your updated windows, you’ll have a couple of materials to choose from. Here’s how they rate for energy efficiency:

  • Top insulation: Wood windows rank very well for insulation, since wood naturally transfers a lesser amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate similarly to wood, along with the fact they won’t melt or break down when faced with temperature shifts. Made for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are designed to work with your budget while keeping your residence energy-efficient. With several chambers, these frames help limit heat loss and boost efficiency.

Quality Window Installation is Important

Good installation is just as essential as the glass and window frame material you pick for your new windows.

That’s why you’ll want to select with a company like Pella of Kelowna, who is skilled in this service. We employ exclusive installation methods to make sure your new windows are a good fit. This stops gaps and cracks that can allow in moisture and air that compromise your comfort.

You can also depend on our team to be thoughtful toward your home during your no-mess, no-guess installation day. They’ll clean up after they’re done and will even haul away your old windows.
