Behind the build of energy-efficient, stylish and durable entry doors.

Entry doors do more than welcome guests — they protect your home, enhance curb appeal and improve energy efficiency. The Therma-Tru Complete Door System combines all these benefits into one comprehensive solution designed to perform, protect and preserve. Explore what makes this system the smart choice for modern homeowners and building professionals.

What Makes the Therma-Tru Complete Door System Different?

The Therma-Tru Complete Door System stands apart from traditional entry door solutions through its integrated design approach. Rather than piecing together separate components, this system combines energy-efficient entry doors, advanced weatherstripping, reinforced frames and premium hardware into one cohesive unit.

Built on the principle of "Perform, Protect, Preserve," the system delivers superior weather resistance, thermal performance and aesthetic appeal. Homeowners benefit from reduced energy costs and enhanced security, while building professionals appreciate the system's reliability and design flexibility across projects.

Energy Efficiency That Saves Money

Energy-efficient entry doors form the foundation of the Complete Door System, featuring a pressure-injected foam core interior proven to provide four times the insulation of a wood door. Advanced weatherstripping and door sweeps create tight seals that prevent drafts and air leakage, while internal insulation maintains comfortable indoor temperatures year-round.

The system's enhanced sealing technology also works together to minimize energy loss. Multi-point weatherstripping creates barriers at critical contact points, while adjustable door sweeps accommodate seasonal expansion and contraction. These features combine to reduce heating and cooling costs, making it an investment that pays for itself over time.

Durable Materials Built to Last

When comparing fiberglass vs. wood doors, fiberglass is the clear, preferred choice for durability and strength. The Complete Door System utilizes fiberglass construction that resists warping, rotting and denting, which are common problems with traditional wood doors and less durable front door materials. This stand-out material also maintains its appearance and performance for decades with minimal maintenance.

Weather-resistant entry doors also handle extreme conditions without compromising structural integrity. For example, flush-glazed glass is designed and tested to withstand wind forces up to 167 mph. The fiberglass core provides strength while maintaining the

authentic wood-like appearance. Unlike steel doors that can rust or wood doors that require regular upkeep, fiberglass doors deliver long-lasting performance with only occasional cleaning.

Security Features for Peace of Mind

Modern entry doors must provide robust security, and the Complete Door System delivers through reinforced components and advanced locking mechanisms. In fact, its multi-point locking system provides three points of protection versus a traditional deadbolt. The handleset is easily engaged with a simple 90-degree twist of a thumb, which engages locking pins at the top and bottom of the door for additional security.

The system’s reinforced door cores and strengthened composite frame construction offer 30% more protection against forced entry attempts than steel and reinforced frames. Plus, heavy-duty hinges prevent warping to ensure smooth operation over time

Customizable Design Options

These secure and insulated exterior doors combine protection with energy efficiency, giving homeowners comprehensive security, all without sacrificing comfort or style. Therma-Tru door collections like Classic Craft, Smooth-Star and Fiber-Classic offer extensive customizable front door options and stylish front door designs to complement various architectural styles.

Toughened glass selections provide both security and energy efficiency, with designs ranging from modern vs. traditional entry doors. Decorative glass options maximize natural light while maintaining privacy and thermal performance. Available vented sidelites can also work as small swinging doors to provide ventilation with convenient, removable screens.

Whether you prefer the authentic look of wood grain or the versatility of smooth, paintable surfaces, the system adapts to your vision and serves as the best entry door for curb appeal.
