Door Width Measurement
Measure brick-to-brick at three points: top, middle, and bottom of the opening. Use the smallest measurement and deduct 10mm from it to allow for a proper fit.
Choose from 16 made-to-measure uPVC flush casement window styles for trade, renovation and replacement projects. The flush sash sits neatly within the outer frame for a clean, timber-inspired appearance, with REHAU uPVC options, a choice of colours, glazing and hardware, and individual Style pages for configuration and pricing.
