216" Wide BI-Fold Folding Door - Multiple Heights

1. Independent Pass-Through Door Functionality

Our main pass-through door operates independently AND slides with the other panels for a complete open design. Cheap brands from Home Depot, Lowe's, and discount importers use fixed doors—which defeats the entire purpose of installing a bi-fold system in the first place.

2. Customizable Color Options

Choose from multiple premium colors instead of being limited to standard black or white. Your home deserves better than one-size-fits-all options.

3. Upgraded Energy-Efficient Seal Kits

We invest in superior seal packages on every door, delivering better insulation and lower energy costs year-round. Cheap doors use the worst seal packages available, costing you more in utility bills.

4. Low-Profile Track System

Our upgraded low-profile tracks provide smooth operation and a cleaner aesthetic compared to bulky, inferior track systems found on discount models.

5. Complete, Ready-to-Install System

Our glass arrives professionally mounted in the frames with all necessary hardware included. Many brands force you to purchase hardware separately, mount the glass yourself, and struggle with missing or incorrect parts during installation.

6. Real Warranty Protection

Look closely at those "10-year limited warranties" from cheap brands—they're marketing gimmicks that exclude everything that actually breaks: frosting, hinges, seals, and moving parts. Our warranty covers what matters.

7. Premium Aluminum Construction

We use thicker aluminum and true double-pane systems for superior soundproofing, strength, and longevity. Cheap brands use the thinnest metal possible, leading to bending, warping, and glass hazing within months.

9. Glass Outperforms the Competition

Most door manufacturers quietly rely on 5mm glass, a thinner, lower-performance option that costs less to produce but delivers weaker insulation, reduced sound control, and lower structural rigidity. At Gladiator, we refuse to cut corners. Every door we build uses premium 6mm high-performance glass, engineered to deliver a measurable upgrade in strength, clarity, efficiency, and comfort.

Thicker Glass = Better Everything

Upgrading from 5mm to 6mm may seem small on paper, but it makes a massive difference in real-world performance:

• Stronger PanelsThicker glass provides greater rigidity, allowing larger door sizes with less bowing and flexing—especially important for sliding and folding systems.
• Better Energy EfficiencyOur 6mm / 20mm argon / 6mm insulated unit achieves a center-of-glass U-Factor of 0.23, far superior to the typical 0.28–0.35 seen in standard 5mm IGUs.
• Superior Whole-Door U-FactorCombined with our upgraded frame system, our doors achieve a whole-door U-Factor of 0.29, outperforming common aluminium door systems.
• Higher Solar ControlWith an SHGC of 0.25, our glass blocks more unwanted heat, keeping interiors cooler and reducing HVAC costs.
• Improved Sound ReductionThe added mass of 6mm glass enhances acoustic performance, contributing to our STC 35 sound rating—ideal for quiet, comfortable living.
• Enhanced DurabilityThicker glass withstands impact, pressure, and long-term stress better than thin-glass alternatives, extending the life of the entire door system

⭐ Why Other Companies Don’t Use 6mm Glass

Because it costs more.

Most brands prioritize cost savings over performance, sticking with 5mm glass that is easier and cheaper to manufacture. But the tradeoff is:

• weaker structural performance
• higher energy loss
• louder interiors
• reduced stability on large openings

We designed our system to maximize performance, not minimize cost.That’s why every Gladiator door comes standard with premium 6mm insulated glass, the same thickness used in high-end commercial systems.

10. Code-Compliant and
Hurricane-Rated Options

Many discount brands don't meet building codes. Our doors can be installed with proper permits, and we offer Miami-Dade hurricane-approved options for maximum protection.

The True Cost of "Savings"

Saving 30-40% on a cheap door might seem attractive today, but when you're replacing it in two years due to hazing between glass panes, malfunctioning hardware, or structural failure—plus paying another contractor for reinstallation—you'll spend far more than if you'd chosen quality from the start.

Factory-Direct Advantage

Choose quality. Choose value. Choose Gladiator.

Most factories still use 5mm basic glazing, which offers limited insulation, lower sound reduction, and weaker overall performance.

We do not compromise.

Our doors come standard with 6mm high-performance insulated glass, engineered with advanced AGC Stopray Vision-52T technology for industry-leading thermal control, solar protection, and acoustic comfort.

This thicker, higher-quality glass delivers:

• Better insulation (lower U-factor for improved efficiency)
• Improved soundproofing thanks to greater mass
• Higher structural strength for large panels
• Superior solar heat control (low SHGC)
• Modern neutral tint and high light transmission
• Significant performance upgrade vs. 5mm glass

Your home stays cooler, quieter, and more comfortable — while reducing energy costs year-round.
