The features of plantation shutter L frame
An L frame, as its name suggests, is designed the shape of letter "L". Which can be used either inside mount or outside mount.
L frame-inside mount
The L frame can be used as a recess fit or fitted to a wall or architrave and used as a face mounted frame. The L frame provides a clean look by allowing the slim, squared frame by only having a 25mm wide frame. With a recessed L frame, you need to consider the type of window frame the plantation shutters will be sitting inside. A lot of windows aren't squared, so for an L frame recess fit shutter, caulking will be necessary.
L frame-outside frame
The face fit L frame suits many applications, though the most prevalent reason for selecting a face fit L frame is if you have limited space between the front edge of the window frame and the window pane. If you have less than 70mm between the glass and the front of the window frame. A face fit L frame is the best options.
Commonly used L frame specifications are L50, L70, L90, BL90, BL100. Of course, can be customized according to the customer needs.
