Finally, wood windows that are nearly as rot-proof as vinyl, shrug off insects like aluminum, and are warmer than both of them.
CoreGuard is the best wood protection in the window industry. And only Hurd has it. CoreGuard actually penetrates through the entire cross section of wood; all the way to the very core of the wood. It contains three active fungicides, an insecticide, plus water repellents to provide envelope protection against pests and rotting. Most importantly, only CoreGuard has a final, proprietary ingredient that goes completely through the wood for the ultimate in protection. CoreGuard is patent-pending and naturally organic, so it’s environmentally friendly. Since CoreGuard repels water, Hurd windows have superior dimensional stability against warping and swelling.
