SAFE WINDOWS

Windows from KAHN are designed to offer reliable protection against the most significant external factors. They effectively block cold from entering your home, thanks to the exceptional thermal insulation provided by Kornice systems. These windows also ensure excellent defense against noise, wind, and water infiltration. For added security, optional specialized fittings can be installed, enhancing resistance to forced entry and providing anti-burglary features.

ENERGY-SAVING

High-quality windows are energy-efficient, designed to keep your space warm and equipped with perfectly crafted gaskets. Installing them in your home, office, or apartment can significantly minimize heat loss—by up to several dozen percent—resulting in substantial savings on heating costs. Choosing windows with the right level of energy efficiency is now a legal standard, ensuring that only top-performing options are suitable for modern construction projects.

ISOLATION

Windows should effectively shield interiors from all unwanted external factors, including noise. Acoustic insulation is a key requirement for modern windows, and the solutions offered by KAHN meet this expectation in full. While standard windows provide good soundproofing, certain environments demand enhanced noise reduction. To address these needs, KAHN offers additional options that significantly improve acoustic insulation.

GLASS

Windows from KAHN are compatible with the most advanced glazing packages, delivering top-tier performance parameters available on the market. The insulating glass units typically feature two-pane configurations; however, three-pane packages are increasingly becoming the standard. Additionally, select systems offer the option of four-pane packages, further enhanced with warm-edge spacers for superior thermal efficiency.
