Air vents are an essential ingredient of all homes and commercial buildings that utilize forced air heating and cooling systems, also know as HVAC systems. After years of relatively uninteresting air vents designs, there has been a resurgence in interest in the styling of air vents. Flush mounted wood air vents create an elegant look for those who are laying new hardwood floors, as you can see here. In addition to the standard red oak air vents, they can also be made to order in a variety of exotic or not so exotic woods. This makes complementing the styling of wood cabinets a snap. Metal air vents are often of interest since the durability is excellent. This is especially true in the case of cast bronze or types of cast metal air vents. Even cast resin air vents are available, which when painted are indistinguishable from cast metal air vents unless one has x-ray vision.
