Tru-Defense is the new standard in high performance doors, components and certified systems, designed to work together to protect homes from severe weather. Therma-Tru’s Tru-Defense certified entry and patio doors have an air, water and structural performance rating of DP-40 or higher. The complete door systems are independently tested, and certified by the National Accreditation and Management Institute (NAMI).

The DP-40 rating indicates that the unit passed a structural test pressure of 60 lbs. per sq.ft. equal to 150 mph winds and a water penetration test under conditions equal to 8” of rain per hour driven by 49 mph winds; and an air infiltration test pressure of 1.57 lbs. per sq.ft. equal to 25 mph winds.

The Fiber-Classic® Hinged Patio Doors offer an exterior wood grain look, while the interior is ready to stain or paint. Smooth-Star® Hinged Patio Doors feature a smooth, crisp surface that rivals the look of fine painted wood. The interior can be painted any color to match your décor. Both provide the guaranteed performance that makes Therma-Tru fiberglass entry doors the most preferred brand in the industry.

Therma-Tru’s Tru-Defense systems for fiberglass hinged patio doors are designed to work together as an integrated system, a feature that most other door manufacturers do not offer. All the components in the new Tru-Defense systems maximize the seal between the door and the frame, virtually eliminating air and water infiltration.

Fiber-Classic and Smooth-Star Patio Door Systems offer the ultimate in style, performance and durability. Both are available in a wide variety of sizes for new construction and remodeling, including 6’6”, 6’8” and 8’0” tall systems. They come in four factory finished exterior colors: White, Almond, Stone and Bronze. All Tru-Defense hinged patio doors feature standard flush-glazed Low-E glass, high-heat composite frame, and other new components such as the high dam sill with Satin Nickel finish, astragal, corner sill pad, door bottom sweep and multi-point locking system, that are all designed to maximize the seal between the door and the frame. Optional adjustable hinges and profiled internal grid patterns or external grilles are available as well.

Fiber-Classic Hinged Patio Doors offer a full system lifetime limited warranty and Smooth-Star Hinged Patio Doors are backed by a full system 20-year limited warranty. This new line of Tru-Defense Hinged Patio Systems includes single, center-hinged, jamb-hung or French door configurations.
