User-friendly: the window's 95˚ opening
makes for easy maintenance.

Weather seals: High-quality continuous
compression weather seals on frames and
sashes for maximum air and water tightness.

Secure: even when the window is
open for ventilation, its partial
opening in the upper part of the sash
limits the risk of forced entry and
protects children and adults against
