ALLER-GUARD
Aller-Guard forms a resistant seal that helps to reduce outdoor dust and dirt particles from entering doors and windows. It's patented and also tested to resist mold and mildew. Reducing the infiltration of these allergens and pollutants provides for a cleaner, healthier and more comfortable indoor environment. Aller-Guard weatherstripping resists allergy-aggravating pollen, fungi, mold, dust, dirt and bacteria.

PPG SELF-CLEANING GLASS
In a photocatalytic process, ultraviolet (UV) light from the sun energizes the SunClean Self-Cleaning glass to help slowly break down and loosen dirt. Since UV light is abundant even on cloudy days or in shaded areas, this process works non-stop throughout the day.

The coating also has a hydrophilic property that makes water droplets spread out, or sheet, across the surface of the glass. When rain or a light spray from a garden house hits the window, the water carries away the loosened dirt. This sheeting action, which works throughout the day and overnight, helps the window dry quickly with minimal spotting or streaking.
