Energy Smart Quality Vents balance security, beauty and perfect ventilation. They are designed to allow fresh air to pass through a building, yet they are well insulated for twice the energy efficiency as our standard vents. We offer several options for size, color and energy efficiency. The superior insulating value of our vinyl mainframe is because of the pure virgin vinyl and hollow chambers within the main frame. The vents we use are designed to adhere to mortar and silicone. Our vents are durable, efficient and crafted from the best materials to meet the highest standards. Our experts can help you with product specifications.
