Composite frames and weather-resistant fiberglass skins prevent rot, rust, denting, and insect infestation.
Polyurethane foam cores provide up to four times greater thermal R-value than typical wooden door panels.
Factory-mated slabs, multi-point locksets, corner seal pads, and sills form an integrated barrier against wind and rain.
Dedicated commercial project quoting, dimensional schedules, rapid lead times, and jobsite logistics coordination.
Therma-Tru offers an industry-leading selection of architecturally curated fiberglass and steel entry doors. From authentic woodgrain textures to minimalist contemporary aesthetics, every door is crafted to exceed demanding international standards.
Combines the warmth and texture of fine hardwood with the low-maintenance resilience of patented fiberglass. Formulated to withstand harsh environmental extremes without swelling, twisting, or peeling.
Designed as the premier alternative to steel doors. Features an ultra-smooth, high-density surface engineered for custom paint finishes with crisp shadow lines and lasting structural integrity.
Delivers bold clean lines, modern asymmetrical glass inserts, and flush-glazed framing designed to complement mid-century, minimalist, and contemporary architectural elevations.
Formed from 24-gauge galvanized steel skins for enhanced security, strength, and durability. Ideal for multi-family residential entrances, house-to-garage fire doors, and commercial applications.
Transform standard doorways into commanding architectural statements. Fully matched sidelite panels and continuous transoms introduce natural ambient daylight while maintaining energy performance.
A true Therma-Tru door functions as an engineered system. Includes composite jambs, multi-fin bottom sweeps, rot-resistant composite sub-sills, and factory-matched compression weatherstripping.
Unlike conventional wood doors that swell in high humidity or bare steel doors susceptible to coastal rust and thermal conductivity, Therma-Tru door systems utilize closed-cell polyurethane cores, solid structural composite rails, and marine-grade fiberglass skin technology.
Tested to rigorous NFRC criteria, dramatically lowering U-Factors and Solar Heat Gain Coefficients (SHGC) for worldwide climatic conditions.
Reinforced strike plates and multi-point tongue-and-bolt locks distribute perimeter pressure evenly to prevent bowing and forced entry.
Patented wood-composite joints isolate timber elements from concrete contact and pooled surface moisture, eliminating rot risks.

Send an InquiryTherma-Tru fiberglass doors replicate genuine wood grain without the structural weaknesses of natural timber. They do not warp, split, rot, or absorb moisture, and they resist surface dents and scratches far better than standard steel. Filled with high-density polyurethane insulation, they offer exceptional energy savings in extreme climates.
Yes. Therma-Tru Profiles and Traditions steel lines provide certified 20-minute and 90-minute fire ratings suitable for commercial corridors and garage entries. Additionally, impact-rated glass and heavy-duty structural composite options are available for coastal wind-borne debris zones.
A complete Therma-Tru door system includes the pre-hung door slab, composite jamb and sill system, precision dual-bulb weatherstripping, corner seal pads, adjustable security strike plates, ball-bearing hinges, and matched sidelites or transoms if specified.
