Outline your exterior windows with decorative wood shutters. Western Red Cedar provides a great wood for your shutters. Warm up your interior doors with the addition of fixed louvers in the panel design. Add a raised or flat panel for contrast or keep a traditional appearance. Consider using a pair of louver doors for your closet. Dress up your bi-fold panels with fixed louvers over a panel. Need a mechanical room door to allow for ventilation, choose fixed louvers.
