Tradition With Technology

Run–Thru Sash horns create an attractive alternative to the traditional vertical sliding window.

Available in both white and foiled options they are designed to appeal to homeowners looking to replace traditional sash box windows with a more cost effective and virtually maintenance free alternative.

These are fabricated by milling the profile into shape as opposed to the less effective screw on method.

The system provides safe cleaning of both sashes from the inside, security, high performance and aesthetically pleasing designs. Where required profiles can be formed to provide arch heads to match existing building details.
