PVC Shutters are a painted product just like timber but are heavier in construction than their timber cousin and installation restrictions may apply.
Painted Timber Shutters are considered the top of their class for interior shutters. The only shutter type that can also be custom made to suit special shape windows with angles, arches or round.
Fixed Louvre Shutters are used for decorative purposes on either side of a window outside or as cupboard doors, room dividers and screening.
