Envisage UPVC Flush Windows – The benefits of UPVC and the great looks of painted timber, made in Britain.
UPVC flat windows

Envisage UPVC Flush Windows are designed to replicate the style of the traditional craftsmen made glazed timber window, the flush casement is characterised by the simplest of lines, just as they would have done if they had been made in the carpenter’s workshop. The opening lights (vents) do not stand proud of the frame. Maintaining authentic proportions, the flush casement can be complemented with a range of both period and contemporary colours and hardware, allowing you to create the finish that matches the style of home.

Oak style UPVC flush windows

What makes Envisage Flush Windows different is their style and their exceptional performance, security, insulation, bringing the traditional timber look into the 21st century. A flush design suits heritage properties, rustic new builds, and minimalist contemporary architecture. The flush window simply describes a style where the sash/opener fits flat within the frame with no protruding areas showing when closed. Modern flush sash windows are much more advanced than their original timber counterparts, featuring the latest multipoint locks and internal glazing beads as standard.

Envisage flush windows have the option of a thicker deep bottom rail to all opening and dummy vents, the standard frame thickness is 60mm, but the deeper option, when chosen, takes the bottom frame up to a chunky 90mm deep. A craftsmen carpenter would probably be best placed to explain why this tweak, though small is actually important to the overall look and feel of this window. This feature helps to emulate the overall appearance of a traditional timber window.
