What Cool In Summer And Warm In Winter Means With Replacement Windows
You’ve probably heard New Hampshire replacement window companies talking about how their windows will keep you cool in the summer and warm in the winter. While it sounds wonderful, you probably haven’t considered what that actually means.
Well, it’s all about heat loss and how modern windows are better at eliminating it than some solid walls. Rather than magic, it’s all done with careful design and superior technology.
Understanding Heat Loss
Heat loss is a single phrase with what would seem two meanings, but really, it’s just two points of perception. A better phrase might be climate loss, as in the controlled climate of your home, but we don’t make the rules.
The real concern is the infiltration of outside temperatures into your home’s interior. In summer, the concern is keeping that hot, muggy air outside and, in the winter, keeping those frigid temperatures as far away from your family as possible.
Both of these worries are answered by the design of modern replacement windows. To put it simply, they keep the outside out and the inside in. They accomplish this by all but eliminating temperature transfer through the glass and frame. This transfer is what is considered as heat loss, and it can happen in either direction.
You can lose heat out an older window during the winter and gain heat through the window during the summer. Either circumstance results in higher energy bills month to month, regardless of the season.
How Replacement Windows Stop Heat Loss
Heat loss was first attacked through the advent of double-pane windows. The air between the panes acted as an insulator, preventing the easy transfer of heat through the glass. The air was eventually replaced with an inert gas called argon and, more recently, krypton. However, krypton is exceedingly rare and ludicrously expensive, so its use is rare.
Inert gases work much better than air at insulating the two panes from one another, making for superior windows. Unfortunately, there was an additional problem with older replacement windows, which their success made apparent.
While heat loss through the glass was vastly reduced, heat loss through the frame wasn’t addressed at all. With the glass no longer affected by outdoor temperatures, the issue with the frames stuck out like a sore thumb.
So, while much of the problem was solved, there was still a long way to go before all heat loss issues would go away for good.
New Frame Designs And Proper Installation
Modern manufacturers discovered that redesigning how the different parts of the frame interlock and filling the spaces with foam gives their windows a level of insulation that rivals your home’s walls.
They also started making smarter decisions on the materials they used to build their frames, using materials less prone to movement and temperature transfer even in the most extreme weather.
They then turned their attention to installation materials and procedures. Soft insulation like fiberglass was shown to soak up moisture and cause the wood around the window frames to rot. So they replaced materials like fiberglass with materials that wouldn’t soak up moisture, like rigid foam, and would prove to be even better at preventing heat loss without the risk of rotting away the wood around your windows.
Flashing procedures and materials were also upgraded and, soon enough, replacement windows were virtually impervious to outside conditions.
Modern Replacement Windows
Standard windows can account for up to 40% of the heat loss in your home. Today’s replacement windows, when properly installed, perform as well as a solid wall at keeping outdoor temperatures at bay. On the coldest day of the year, you might notice a mild temperature drop on the glass inside your home, but nothing close to the old days of frost inside your home.
The result of all that insulating power is a decrease in the amount of time it takes to heat or cool your home. Less time means less energy usage. But a reduced carbon footprint isn’t the only benefit of modern replacement windows.
The track systems have been improved, with better materials and near-perfect balancing, especially in the double-hung variety of windows.
Sashes move smoothly with little more than a finger’s-worth of effort, and glass coatings protect your home and family from the harmful effects of UV light. And cleaning your windows has become so easy that the old phrase “I don’t do windows” confuses our younger generations.
Replacement windows can also come with security features, integrated window blinds, and a wide variety of shapes, styles, and colors. You can even pick different types of glass and inserts to make your windows unique to your home and only your home.
And, best of all, they help keep you cool in the summer and warm in the winter — no magic necessary.
