It's no secret, I love wood. But lets be honest, technology is cool too. When technology from the space industry makes its way into the building industry markets we get better products for the home. Case in point fiberglass doors. ThermaTru, Masonite, and PlastPro are three manufactures that are excelling in this exciting new technology. Why fiberglass? Because the trees we are harvesting these days are new growth, which means alot of sapwood, which is softer than the heartwood. To make a very long and complicated discussion short, the wood we get today is nowhere near as durable as the old growth of yesteryear. So fiberglass is coming into the market as a nearly industructable substitute. The technology is now to the point to where a good finisher can make fiberglass doors fool even pros like me. Heres one we did for a family in Napa.
