Castlewood Doors are built using engineered construction. Door stiles have a warp resistant timberstrand core along with a resawn solid wood veneer ranging from 1/8” to 1/4“ thick. Interior door panels are solid wood. Exterior panels are separated by a plywood core to allow freedom of movement to accommodate the different climates of the interior vs the exterior of your home. All doors are constructed using 1/2” x 4” dowels in addition to the mortise and tenon jointery. Constructed using Formaldehyde-free glue.
