A building product is configured for attachment to a surface of a building. In one example, the building product includes a siding product including a first side and a second side. In one example, the siding product is a pultruded product. A first engagement feature is disposed on or near the first side. A second engagement feature is disposed on or near the second side. The second engagement feature is configured to selectively frictionally engage with the first engagement feature of another similar siding product such that any curvature in the siding product increases frictional engagement between the siding product and the other similar siding product. In one example, the building product includes a spacer clip for attachment of the building product to the surface of the building.
