Modern windows come with a host of features that are designed to help them resist the elements and last longer. Since most, if not all, of these features also enhance a window’s energy efficiency while protecting against moisture damage, it’s a win-win situation. The fact that energy-efficient windows are generally warmer than older, non-energy-efficient ones also goes a long way towards preventing moisture damage.
Some of these moisture-protecting features include: *render as icons; but feel free to do something else if you think that will look better*
- Low-E coatings: A Low-E, or low emissivity, coating is a thin, transparent layer of coating applied to the inner glass panes of a window to prevent indoor heat from escaping without affecting the level of natural light streaming through. Because low-e coatings help to keep indoor heat in, indoor temperature is stabilized, lessening excessive cooling in windows. There remains water vapor in the air but with windows less cool, it is unlikelier for condensation to form on them, preventing moisture from pooling and causing damage.
- Inert gas fills: Instead of just normal air, manufacturers use inert gases like argon or krypton in between glass panes to increase the insulating capabilities of a window. Gas fills slow down the transfer of heat between panes, allowing windows to avoid heat-related damage. This means window seals also last longer, preventing moisture from finding its way into the frame.
- Frame material: Traditional construction materials like wood and metal are susceptible, in different ways, to damage from too much moisture. Choosing frame materials then that are either impermeable to or unaffected by moisture will go a long way towards helping a window avoid damage. Take composite materials, for example. They may be made to look like wood but they do away with the material’s weakness to moisture, preventing not just moisture buildup, which leads to rot and decau, but also mold and mildew growth that reduces a window’s aesthetic appeal.
While your windows are capable of resisting moisture damage, there’s a lot you can do as well. More on this in Part 3.
