When this is done to a window, the amount of cold or heat from either side transferring to the other side is greatly reduced. When this is accomplished, the feature is called thermal barrier. Do this to an aluminum window and it is now a thermalized aluminum window.
When it comes to the performance of a thermalized aluminum window, these fantastic windows easily outside other types of windows regarding the strict and tight specifications of the window industry. Your home risks up to 25 times the amount of leaks from an old window or a window that hasn’t been thermalized. Old, leaky windows are contributors to condensation, rotting or warped frames, and higher electricity costs.
It should be noted, however, that absolutely no window can be completely free of ever having condensation. The quick changes of temperatures indoors and outdoors, from something as simple as the sunrise on a very warm day can cause a bit of moisture to collect. This does not mean a thermal window is faulty or just doesn’t work. Please keep in mind that the window itself can not cause the moisture that develops, it can only work hard to keep it to a minimum.
What the thermal window does is keep the moisture indoor or outdoors from escaping and then collecting on the glass. Think of it this way, if there is condensation on the inside of your thermalized window that seems a little excessive and does not go away almost immediately (less than an hour), then any reputable window company will bet money that the surrounding walls and other windows show the condensation too. It is just a fact of life: sometimes condensation happens.
Lets talk a little bit of numbers really quick. There is a recommended humidity level for interiors that make thermalized windows perform at their absolute best. Anywhere from fifteen percent humidity to forty percent humidity is ideal for the home. This also takes into account the act of doing things that produce excess humidity in the home, such as using the shower or cooking. Honestly, most homes have been updated or have been built with new techniques to conserve energy, which keep humidity levels very low, also helping the problem with condensation.
