Siparila Topcoat® wood siding profiles are designed to hide unsightly nails. Our siding also uses end-matched panels to hide joints and this feature, along with the tongue and groove paneling, makes the wood siding easy to install. Hiding the nail heads helps to prevent water damage to the wood and increases the siding’s durability. If you value quality materials, aesthetics, and ease of installation, then Siparila Topcoat® wood siding is for you. Your home, business, or construction project will benefit from the straight-grain durability of Scandinavian wood. Its high quality also means there’s no need to repaint the wood siding for the duration of the 15-year warranty.
