In the 1990s, automotive manufacturers introduced a clever design innovation known as “window indexing” or “automatic window drop.” This feature, commonly found in German cars with frameless doors like BMWs, allows a car window to automatically lower slightly when the door opens and then raise again to seal tightly when the door closes. This ensures a snug, weather-resistant fit by pressing the window into its frame.
A similar concept—though far less high-tech—has been effectively adapted for residential garage doors by a company called ThermoTraks. Recognizing that garage doors are often the most leak-prone part of a home, ThermoTraks developed a perimeter sealing system paired with a uniquely engineered door track. This system combats drafts and heat loss in a smart, mechanical way.
The innovative track design features intentional bends or “kinks” where the garage door wheels rest in the closed position. These slight deformations push the door outward, pressing its edges firmly into flexible weather seals. The result is a more airtight garage door without the need for electronic systems.
For homeowners in Boston looking to improve their home’s energy efficiency and eliminate drafts, Garage Door Experts of New England is the ideal choice. Their familiarity with advanced systems like ThermoTraks, combined with expert installation and superior customer service, makes them the go-to professionals for sealing and insulating garage doors effectively.
