Therma-Tru Introduces Stainable Astragals

MAUMEE, OHIO – Therma-Tru Corp., the nation’s leading manufacturer and most preferred brand of entry doors, now offers a stainable astragal that combines beauty and performance for use in any Therma-Tru® grained double-door application.

Available in three wood-grained textures --- Oak, Mahogany and Fir --- to complement all Therma-Tru grained fiberglass door systems as well as home interiors, the stainable astragal is designed to deliver durability.

"High-strength aluminum construction helps provide stability, holding power and lasting performance," says Derek Fielding, senior product manager for Therma-Tru Corp. "The wood-grained textured vinyl wrap resists water damage, bubbling, cracking, chipping and peeling. It also works perfectly with our Same-Day® stain for faster drying time than traditional stains and the authentic look of real wood, complete with a five-year limited warranty."*

The stainable astragal is designed for easy installation and finishing with features such as pre-machining for easy attachment to the passive door and removable boot, trim and weatherstripping that allow for convenient trimming and finishing without masking.

"Like all Therma-Tru components, the new stainable astragal is designed to complete our door systems," says Fielding. "It delivers a universal fit in double-door applications to help seal against air and water leaks. The locking steel slide bolt, steel bolt spring, weatherstrip and boot work together to provide a tight seal at the sill, head jamb and lock side of the entryway."

Available in 7'8" width by 6'6", 6'8", 7'0" and 8'0" heights, the stainable astragal can be ordered to fit multiple configurations, including undersized options. It features third-party certified structural performance up to DP-40 when installed in a Therma-Tru door system** and can be used in a Therma-Tru Tru-Defense® door system for outstanding weather protection backed by a warranty rider. The astragal is also included in the full-system limited lifetime warranty for all Therma-Tru fiberglass door systems.
