Douglas Fir, Western Hemlock and American Red Oak provide the raw material - Simpson design and craftsmanship provides the rest. State-of-the-art technology goes into every Simpson Mastermark® door, assuring you of outstanding performance. For example, the patented Innerbond® panels carry a lifetime warranty against splitting through. Engineered components resist warping and twisting. And triple glazed leaded glass inserts reduce heat loss and enhance appearance.
