The Andersen casement is the first in the world to have been "Owl Mark" approved by the University of Birmingham's Centre of Applied Gerontology for its specially developed easy-to-use winding handle, particularly suitable for the older generation and the disabled.

Andersen's range of gliding and Frenchwood® Hinged patio doors are designed to give easy access to wheelcahir users and the physically infirm. Convenient and easy to operate, both the Gliding and Frenchwood® Hinged patio doors are available with a clear opening that exceeds 800mm in accordance with Building Regulations Part M on provisions for disabled access and facilities.

Exterior and interior easy access wheelcahir ramps can also be provided, complete with track cover. All hardware and locking systems are easy to grip and located conveniently within reach of most wheelchair users.

To offer greater protection to children, Andersen can also supply a specially designed T-shaped handle, which makes it more difficult for children (aged five and under) to open the window.
