Cypress siding may be temporarily stored outside if at least 4 inches off the ground and on a flat, well-drained surface protected from moisture with a shed pack or waterproof cover. Do not seal the unit because ventilation is necessary to prevent condensation and ground moisture absorption, which may cause mildew or mold. Special care should be given to material that has become wet during storage because it may shrink and open gaps at the joints after application. The Bevel and Williamsburg patterns are installed horizontally. For siding purposes, other patterns should be installed vertically.
Some patterns also lend themselves to diagonal installation.
Most patterns can be installed vertically or horizontally for interior use.
