288" Wide BI-Fold Folding Door -Title 24 & NFRC Approved

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.
