Elegant and stylist

PVC-U casement windows are the most popular style in the UK.  They are characterised by outward opening vents which are combined with fixed panels (lights).  Crystal Direct can manufacture almost any size and style!

The profiles are slim, but strong and insulating.  When combined with high quality glazing, they create a thermally efficient window which is robust and easy to maintain.
