Single, double & triple Easy Clean timber sash windows.
Suitable for high-rise buildings and complement both traditional and modern architectural styles.
TRC’s Easy Clean Sash Windows combine the appearance of a traditional sash with a modern tilt-and-slide mechanism. Each sash can tilt inwards up to 50 degrees, making it possible to clean panes and frames safely from inside the property – a practical solution for upper floors or difficult-to-reach areas.
Built from sustainable, engineered timber, these windows are factory finished with a durable three-coat microporous paint or stain. They achieve U-values as low as 1.4 W/m²K, with tested weather performance including Class 4 air permeability, Class 5A water tightness, and Class 4C wind resistance.
With options for glazing types, ironmongery, cill projections and finishes, the Easy Clean Sash Window provides long-term durability, flexibility, and a simple way to maintain traditional character while meeting modern performance standards and functionality.
