Premium Basement Window Installation

Explore our Premium Basement Window Installation services at Connecticut Cellar Doors, where we exclusively utilize Low Emissivity (Low E) glass filled with Argon gas for optimal efficiency. Low E glass, a thin layer of metal oxide on the glass surface, provides year-round benefits. In warmer temperatures, it filters out heat and UV rays, keeping your basement cooler, while in colder weather, it allows sunlight to warm the interior. This energy-efficient feature reduces heating and cooling costs regardless of external conditions, making the most of natural sunlight.

Our dual glass basement windows are filled with Argon gas for superior insulation, ensuring increased energy efficiency.

Argon gas is a colorless, odorless gas found in our atmosphere. Argon is denser than air making it an excellent insulation material. By replacing the air between the two panes of glass with Argon, our windows provide increased insulation for your basement.
