Traditional English DM Casement Flush Windows have great aesthetic merit. In addition to that, their careful design pledges to keep every home wonderfully warm, quiet and extra safe. Excellent thermal and weather performance is guaranteed. Our challenge was to make casement windows that look simple but are in fact very sophisticated. Hidden away is modern technology – warp resistant timber, Secured by Design locks engage in multiple points around the perimeter of every opening, ventilation grooves, drainage channels and glazing units which lose much less of the heat in comparison with ordinary windows. In short, this DM Casement Window in timber replicates the typical features of traditional English design without compromising performance.
