Siding may be made of wood, metal, plastic, or composite materials. It may be attached directly to the building structure (studs in the case of wood construction), or to an intermediate layer of horizontal planks called sheathing. Two Uncles offers several quality siding brands. Each features a broad selection of siding colors, profiles, textures and panel thickness. We also offer a complete selection of vinyl and aluminum trim and accessories so you design an exterior that reflects your own personal taste.
