• CUSTOM SIZE: This window board can be CUT TO YOUR SPECIFICATION and arrives BULLNOSED on one long edge.
• PROFESSIONAL FINISH: By using the dropdown box above, you can customise the ENDS of the window board to be either RETURNED (ROUNDED) for a PROFESSIONAL-LOOKING FINISH, or you can choose to KEEP THE ENDS SQUARE if that is your preference.
• WIDE WINDOWBOARDS: For WIDTHS OVER 270mm, the window board will be made in sections and JOINED TOGETHER, this enables us to achieve wider sections of window board while at the same time provides overall STRUCTURAL STRENGTH.
