We offer the most defining E-Vent moulding profiles and the smaller finishing touches that give E-Vent systems a refined and complete appearance when applied to a diverse range of home exteriors. The joining block is crafted with precision in molded urethane, a material that molds with the detail and beauty that makes it a modern favorite. Urethane trim products are rigid and durable, but also lightweight and easy to install. When compared to wood, urethane maintains a traditional appearance while offering the moisture resistance of this modern polymer. Joining blocks will not warp, crack, decay or offer a food source for insects. The block is also pre-primed.
