Whether it is decorative or functional, adding a polyurethane louver is the ideal way to dress up a gable or fill an empty space on a house’s facade. Functional louvers include a screen that allows good air circulation while keeping insects out of the house. In addition to bringing a decorative touch to any house, functional louvers also provide a good ventilation of the roof by acting as a roof vent or attic vent. With the look of wood, Plastika louvers are resistant, durable and can be factory painted in the colour of your choice.
