These tilt and turn timber windows are overlaid with durable aluminium just on the external face. This reduces maintenance and opens up a wealth of design and colour possibilities.

The technical performance for these tilt and turn windows is impressive. They boast the top rating in water tightness and air permeability tests; and an achievable Uw value as low as 0.8.For peace of mind they also carry Secured By Design approval.

The huge operable sash size (up to 3m high) gives scope for stunning feature windows which deliver natural light and flexible ventilation.

We offer these alu clad windows with either double or triple glazing, a choice of four glass types, and hardwood or softwood frames plus RAL paint finishes.
