Trimworks® accessories are made with the same quality and attention to detail. Many trims and accessories are insulated inside to make the energy efficiency and durability of your siding complete. For example, our beaded and fluted corner posts feature insulated backing inside to add rigidity, insulation, and 300% greater impact resistance. Small animals, birds, and insects can’t nest in these corners. Plus, soffit, trim, accessories, rainware, gutter coil, fascia and trim coil are matched to your siding, thanks to the ColorConnect® Color Matching System.
