Heavy-Duty Exterior Folding Door Series
Folding Door 6' Foot Wide - Multiple Heights Available
Upgrade your space with our high-performance Thermal Break Aluminum Sliding Glass Door, a top-tier choice for modern home and commercial applications. Engineered for maximum durability, thermal efficiency, and superior wind resistance, this heavy-duty exterior sliding door combines sleek aesthetics with cutting-edge functionality.
Why Our Bi-Fold Doors Stand Above the Rest
Not all bi-fold doors are created equal. Unlike the mass-produced, low-cost doors you’ll find online at big-box retailers like Home Depot, our doors are built to withstand extreme conditions and last for years to come.
✅ Superior Wind Resistance – Engineered to handle hurricanes and tornadoes, our doors boast an impressive Wind Load Resistance of TS EN 12210, 4500 Pa, providing unmatched protection.
✅ Energy Efficiency & Insulation – With thermal insulation of Uw: 2.3 W/m².K, our doors help maintain indoor temperatures, reducing energy costs and keeping your home comfortable year-round.
✅ Stronger, More Durable Construction – Unlike flimsy budget doors, our 1.8mm thick profiles, 77.3mm frame depth, and 56.3mm panel width create a robust structure that won’t warp or break over time.
✅ Industry-Leading Warranty – While cheap door factories offer 1-5 year warranties, we stand behind our quality with a long-term, proven warranty for peace of mind.
Don’t settle for the cheapest option—invest in quality. Keep your family, tenants, and property safe with bi-fold doors designed to withstand the toughest conditions. Choose Gladiator Windows & Doors—a name you can trust.
