Summer. So relaxing. But not if you’re a homeowner desperately trying to keep your house cool while you manage the air conditioning costs. You know that you are wasting precious energy and that your utility bill is skyrocketing along with the thermometer. Is there anything else you can do to keep your home’s interior cool during the hot summer months? And what if you live in a steamy, hot climate all year round? Is there a solution?
Well, yes, there is, and believe it or not-the answer is in your windows and doors. Buying the right replacement windows and sliding doors really can keep the summer heat on the outside, where it belongs. That’s because windows and doors are more energy efficient than ever these days, thanks to both advanced window science and government energy efficiency regulations.
Best Windows for Hot Climates and Summer Days
First, a little Window Science 101:
1. Dual Pane Glass Windows Let’s start here because this is one of the most basic solutions. Dual pane glass windows have an extra sheet of glass that stalls heat from trying to penetrate your windows. It’s simple: heat has to struggle through that extra space between the panes to get into your home.
2. Argon Gas FillEnergy-efficient dual panes these days will be filled with argon, an invisible, nontoxic, odorless gas that’s injected into the space between the two glass panes. While regular air is easily affected by heat, argon is considerably denser than air. The weight of this gas dramatically reduces the amount of heat that can pass through the glass.
3. Low-E (low-emissivity) CoatingOne of the greatest advances in window science is this thin coating of transparent metallic material (silver oxide) that’s applied to window glass for insulating purposes. The Low-E coating helps to prevent heat gain in your home by acting as a kind of reflective shield, pushing radiant heat back to its source. In other words, a Low-E coating reflects the summer’s heat away from your home, helping to keep the indoors cool.
