Hurd windows and doors are truly second to none in the market. Hurd offers the world’s most energy efficient window, the best wood protection in the industry, the longest wood window warranty, plus a supreme selection of options, colors and design choices.

COREGUARD™. Proven protection to the very core.

Moisture, rot and insects are no problem for Hurd windows thanks to their exclusive CoreGuard treatment. CoreGuard actually penetrates through the entire cross section of wood. As a result, the wood windows are nearly as rot-proof as vinyl, shrug off insects like aluminum, and are warmer than both of them.


If your windows can survive rainforest testing, they can certainly survive Houston Texas!

CoreGuard is currently being proven in a Hawaiian rainforest. To maximize the potential for water damage, an independent testing organization took sections of the wood windows, broke the finish seal over the joints, then tilted them to trap rain. After 5 years constant exposure to downpours and tropical sun (the equivalent of 15-30 years under normal installations), the treated wood has shown no deterioration. If CoreGuard can endure these harsh, wet conditions, imagine how well it can perform in normal, Houston weather.
