Nobody wants to invest in a product that compromises visibility, and in this article, we explore the science behind impact windows and their resistance to fog. We’ll uncover the truth behind this popular question and shed light on what you can expect from impact windows in terms of clarity and performance.

Why fogging occurs in windows

Condensation

Fogging in windows occurs when condensation forms on the glass surface. Condensation is the result of moist air coming into contact with a cold surface, such as a window pane. When warm, humid air encounters the cool surface of a window, the moisture in the air condenses into water droplets, causing fogging or a foggy appearance on the glass.

Air leakage

Another cause of fogging in windows is air leakage. If there are gaps or cracks in the window frame or sealant, outside air can enter the space between the glass panes. This can lead to the formation of condensation when the temperature drops, causing fogging to occur. Air leakage is more common in older or poorly installed windows.

Low interior temperature

When the interior temperature of a room is significantly lower than the outside temperature, fogging in windows becomes more likely. This temperature difference can cause the surface of the window to cool, leading to condensation and fogging. Low interior temperatures can be a result of insufficient insulation or inefficient heating systems.

High humidity

High humidity levels in a room can contribute to fogging in windows. When the air is saturated with moisture, any cold surface, such as a window, can easily become a condensation point. Excess humidity can be caused by activities such as cooking, showering, or even just breathing. If the humidity is not adequately controlled, it can lead to fogging issues in windows.

Characteristics of impact windows

Double or triple pane

One of the key characteristics of impact windows is that they typically consist of double or triple pane glass. These multiple layers of glass provide better insulation and reduce the transfer of heat and cold between the interior and exterior of a building. The extra layers also help to minimize the formation of condensation and fogging on the window surface.

Low-E coating

Impact windows often have a Low-E (low-emissivity) coating applied to the glass. This thin, invisible coating helps to reflect heat back into the room while allowing visible light to pass through. By reducing heat transfer, the Low-E coating can help prevent fogging by keeping the temperature of the glass closer to the room temperature.

Argon or krypton gas fill

Between the layers of glass in impact windows, there is often a gas fill, typically either argon or krypton. These inert gases are denser than air, providing additional insulation and reducing the potential for fogging. The gas fill helps to create a thermal barrier that minimizes temperature differences on the glass surface.

Insulating frames

In addition to the glass, impact windows feature frames that are designed with insulation in mind. These frames are typically made of materials such as vinyl, fiberglass, or reinforced aluminum. The insulating frames help to further reduce heat transfer and prevent fogging by maintaining a consistent temperature throughout the window structure.
