Hardwood Plantation Shutters installed in Waterstown Avenue, Palmerstown. These shutters are made from natural hardwood. Z-type of frame on these shutters means that the shutters are fitted on the outside of the window frame. 63mm louvers are our 2nd smallest size available. Choosing a smaller size means you can control light that little bit extra. Bi-fold panels are fitted just over the kitchen window and this allows you to save space if you wish to open them fully.
