Designing Replacement Windows: What Makes a Window Energy Efficient

Designing Replacement Windows: What Makes a Window Energy Efficient

When you’re beginning your project for replacement windows in Vancouver, energy efficiency should top your priority list. That’s since inefficient windows can be responsible for the biggest heating and cooling loss in your house.

They can leak as much as 30% of your heating and cooling, according to the U.S. Department of Energy. So, it’s essential that your replacement windows are the smartest option for the temps in Vancouver.

In designing your new windows, here are a few aspects to think over.

Window Panes: One, Two or Three?

Window panes are one of the most essential parts of an energy-efficient window. We advise choosing no less than double-pane windows, as single-pane windows are very inefficient. They’re also predisposed to losing air and influencing your home’s comfort.

If it will fit your budget, switching to ENERGY STAR® windows will help reduce heating and cooling bills and save you more money in the future. That’s since they work hard to keep your residence’s temp in balance, no matter the weather outside.

On average, ENERGY STAR says regular houses that get these windows can save*:

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

Over the lifetime of your windows, those savings can really collect. And you can also feel good knowing you’re helping decrease greenhouse gas emissions, which helps shield the environment.

Energy efficiency matters to us at Pella. That’s why we’ve affiliated ourselves with ENERGY STAR since 1999 and have 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 buy.

Enhance Your Windows with Glass Options

Adding special coatings and gas between window panes can keep your residence more comfortable while blocking additional ultraviolet rays. No matter where you live, Pella provides an InsulShield® glass style that will fit your individual climate.

Choosing the Ideal Window Frame Material

When selecting your new windows, you’ll have a few materials to choose from. Here’s how they rank for energy efficiency:

  • Top insulation: Wood windows are rated very good for insulation, because wood intrinsically transfers a lesser amount of heat and cold.
  • High durability: Our exclusive fiberglass windows insulate almost identically to wood, plus they won’t melt or break down when faced with temperature shifts. Engineered for lasting durability, Pella’s proprietary fiberglass is the strongest material available for windows.**
  • Budget-friendly: Our vinyl windows are designed to fit your budget while keeping your residence energy-efficient. Including numerous chambers, these frames help limit heat loss and enhance efficiency.

Quality Window Installation Matters

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

That’s why you’ll want to choose with a company like Pella of Vancouver, who specializes in this service. We use exclusive installation methods to ensure your new windows are a good fit. This prevents gaps and cracks that can let in moisture and air that impact your comfort.

You can also count on our team to respect your home during your no-mess, no-guess installation day. They’ll clean up after they’re finished and will even take care of your old windows.
