Timberlane’s Copper Shutter Capping is quite simply a roof for your shutter. Most shutters commonly fail due to water penetration at the joints. Shutter capping eliminates this problem and directs water off and away from the shutter. If you are purchasing Timberlane shutters, custom aluminum drip capping will be included. Timberlane’s shutter capping is sold per linear foot. Customer must provide the quantities and specific lengths of capping desired.
