The Kömmerling 76 AD is a new-generation uPVC (plastic) window system that offers a significant upgrade over older 70 mm profiles, specifically designed for energy efficiency and to meet the requirements of low-energy homes. The "AD" stands for Double Seal (Anschlagdichtung).

Excellent Energy Balance: The window achieves superior thermal insulation using a 76 mm (2.99 inches) installation depth and a 5-chamber profile. It is designed to accommodate modern triple glazing up to 48 mm (1.89 inches) thick, allowing solar heat to penetrate while preventing valuable heating energy from escaping.
Robust and Secure Construction: The system includes built-in steel reinforcement to ensure the frame is sturdy, hard to deform, and has maximum lifting capacity for heavy, modern glazing. It is highly resistant to wind and rain, with a security profile that can be upgraded to Resistance Class 2 (RC2).
Eco-Friendly Material: Kömmerling was the first major manufacturer to use lead-free stabilizers (based on calcium and zinc) in their profiles, adhering to their "greenline" standard for environmental protection and lasting quality.
Design Versatility: The profile features a classic offset sash design with clean, angular aesthetics and narrow sight lines, which maximizes the glass surface area for more light. A wide range of colors and finishes, including wood decors and aluminum cladding options (AluClip), are available.
