Fenstersystem

Fenstersystem refers to a modular concept used in the construction of exterior windows. It comprises standardized profiles, glazing units, seals, reinforcements, and hardware that are assembled to form a complete window frame and sash. By organizing components into families, fenstersysteme enable consistent performance, interchangeability of parts, and scalable configurations for different openings and projects.

Common materials for fenstersystem profiles are PVC-U, aluminum, timber, and composite materials. Each offers different thermal performance, durability, and maintenance needs. System providers supply engineered profile sections, reinforcement standards, glazing beads, gaskets, and accessory parts that ensure compatibility across a range of window types and sizes.

Windows built with a fenstersystem are rated for thermal insulation, air and watertightness, wind load resistance, and acoustic performance. They may carry certifications and satisfy regional standards such as EN 14351-1 for windows and external doors, as well as national energy and safety requirements. Advanced systems support high-performance applications, including passive-house designs.

Typical fenstersystem families include casement, tilt-and-turn, side-hung, fixed, and sliding configurations. Some systems offer multi-chamber profiles, warm-edge spacers, and low-emissivity coatings to improve energy efficiency. Design options cover glazing thickness, color finishes, and hardware such as hinges and locks.

Installation requires compatible building envelopes, correct sealing and drainage details, and continuity of air barriers. Service and maintenance vary by material: PVC-U is low-maintenance, aluminum is durable with long-lasting finishes, and timber requires periodic painting or varnishing and gasket care.

Fenstersystem constitutes a core element of modern fenestration, supporting standardized production, ease of replacement, and a broad range of performance and aesthetic options for residential and commercial buildings.
