Sash Easy Clean Windows

Tilt and slide Sash Easy Clean Windows display traditional styling, yet conceal clever functionality: both sashes also tilt inwards, so the external panes can be cleaned from inside the building.

Tested for acoustic, thermal and weather containment, these easy clean sash windows also come with an enhanced security option if required, compliant to PAS24 and Secured By Design approved.

These easy clean sash windows are ideal for high-rise buildings, and complement both traditional and modern architectural styles.

On our tilt and slide sash windows offer the same design versatility as our other sash windows – hardwood or softwood frames, RAL finishes, and four glazing options (safety, obscured, acoustic and solar control). Windows are double glazed as standard, with triple glazing also available.
