KMD 88 System

KMD.88

Aluminum windows and doors with thermal insulation

The KMD.88 system is designed for the fabrication of window and door structures with increased requirements for thermal insulation, strength, and durability. The frame depth is 80 mm, which, combined with 44 mm polyamide thermal breaks, provides up to 20% higher energy efficiency compared to the KMD.78 system.

The system allows for the installation of glazing units up to 68 mm thick. A two-component central EPDM gasket ensures a high level of airtightness, protection against drafts, and stable thermal performance throughout the entire service life.

The system supports the production of structures of any complexity, including large-format panoramic windows. It also allows for both inward and outward opening doors, as well as various threshold options.
