The Aluminum Bifold Door For Warehouses is a side-folding thermal break door solution engineered for logistics centers, loading docks, and cold storage facilities. Part of DERCHI's 93 Series, this door folds compactly to the side, eliminating the need for overhead tracks and maximizing usable space.
- Side-folding operation saves overhead clearance for HVAC, lighting, and material handling equipment.
- Thermal break profiles with standard 5+27A+5 double tempered glass reduce thermal transfer.
- Fully customizable size, track layout, finish, and glass to match project specifications.
- KERSSENBERG commercial-grade hardware with patented Four-Side Six-Point Lock for reliable security.
Product Details
The 93 Series Aluminum Bifold Door For Warehouses uses aluminum thermal break profiles that interrupt conductive heat flow, a critical advantage for temperature‑controlled environments. Its accordion‑style folding panels stack neatly to one or both sides, removing the need for overhead tracks and avoiding interference with ceiling‑mounted machinery, ductwork, or lighting common in industrial settings. This side‑folding mechanism also allows wide clear openings without the structural headroom required by sectional overhead doors.
Unlike ordinary sliding or overhead doors, a warehouse bifold door opens quickly with minimal side clearance. The concealed adjustable hinges and KERSSENBERG multi‑point locking system, featuring a patented Four‑Side Six‑Point Lock, provide a clean appearance and strong anti‑theft protection. Performance attributes like water‑tightness, wind‑pressure resistance, and thermal insulation are design priorities; actual ratings depend on the confirmed glass and frame configuration and must be verified with project‑specific test reports.
Product Features
Space‑Saving Side‑Fold: Panels fold neatly to the side, leaving overhead space completely free for warehouse infrastructure—no tracks, no interference with lighting or ventilation.
Thermal Break Insulation: Polyamide‑reinforced profiles combined with insulating glass options help maintain stable interior temperatures, supporting energy efficiency in cold chain and conditioned logistics areas.
Multi‑Point Anti‑Theft Lock: The patented Four‑Side Six‑Point Lock engages the door at multiple points along the frame, significantly enhancing forced‑entry resistance for secure loading docks.
Customizable Track Configurations: Straight, 90° corner, or curved tracks, plus low water‑resistant or high track options, adapt the door to existing building layouts and drainage needs.
Heavy‑Duty Hidden Hinges: Adjustable concealed hinges provide smooth daily operation and a flush interior look, with robust load‑bearing capacity for large glass panels.
Durable Industrial Finishes: Powder coating, anodized wood grain, or PVDF coating withstands humidity, temperature swings, and frequent cleaning in demanding warehouse environments.
Customizable Styles
Glass Type: Choose from clear, tinted, Low‑E, reflective, laminated, or triple tempered glass to balance visibility, thermal performance, and safety requirements.
Frame Color & Finish: Aluminum profiles can be powder coated in RAL colors, anodized with a wood grain texture, or finished with PVDF for coastal and high‑UV projects.
Opening Direction & Track: Specify inward or outward folding with straight, 90° corner, or curved tracks; low water‑resistant track or high track options are available.
Size per Project: Panel widths and heights are cut to the millimeter based on door schedule and structural opening, subject to engineering confirmation.
Hardware Finish: KERSSENBERG handles and hinges can be matched to frame color or specified in stainless, matte black, or brushed finishes for a cohesive look.
Hardware Accessories
KERSSENBERG Ergonomic Handle: A robust, full‑grip handle designed for frequent use in industrial settings, with a smooth locking mechanism that confirms secure closure.
Hidden Adjustable Hinges: Concealed hinges allow fine adjustment after installation, maintaining alignment of heavy panels and ensuring consistent operation over time.
Four‑Side Six‑Point Lock: DERCHI’s patented lock system engages the top, bottom, and both sides of the door, significantly improving security for unmanned warehouse entries.
Multi‑Point Locking System: Integrated shoot bolts and locking points distribute the locking force along the entire height, reinforcing the door against wind loads and attempted intrusion.
Optional Magnetic/Electric Blinds & Flyscreen: Integrated 23A magnetic blinds or 27A electric blinds and folding flyscreens can be factory‑fitted into the door panel for controlled light and insect protection.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | Thermal break profiles + insulating glass reduce heat transfer. | Request U‑factor/SHGC values for the exact glass and frame configuration; figures vary per project. |
Wind Pressure Resistance | Engineered per opening size and local wind codes. | Confirm design pressure rating and test reports specific to your building location. |
Water Tightness | Multi‑gasket system and water‑resistant track design. | Ask for water penetration test class according to EN 12208 or similar standard for your configuration. |
Air Tightness | EPDM gaskets and silicone wool strips seal panel gaps. | Provide air infiltration expectations; DERCHI can supply test data upon request after engineering. |
Sound Insulation | Laminated or triple glazing options improve acoustic performance. | Obtain STC/OITC ratings for the chosen glass makeup; results depend on panel thickness and seals. |

Advantages
Overhead Obstruction Eliminated: Side‑folding panels totally avoid ceiling‑mounted tracks, leaving the full opening height free for forklifts, lighting, and ventilation ducts.
Thermal Break Efficiency: Polyamide‑strip profiles and insulated glass minimize thermal bridging, helping maintain stable temperatures in conditioned warehouse zones.
Project‑Scalable Security: The multi‑point locking system and heavy aluminum frame provide reliable anti‑theft resistance without relying on floor bolts alone.
Full Dimensional Freedom: Custom track layouts and panel sizes adapt to irregular openings, whether a single‑leaf pass door or a 10‑panel wide entrance.
Low‑Maintenance Finish: PVDF and powder‑coated surfaces resist corrosion, chalking, and frequent washing—a practical match for industrial and coastal sites.
Application Scenarios
Apartment: Large storage rooms or shared terrace openings where a folding door maximizes access without swinging leaf interference.
Home Office: Ground‑floor studios with expansive glass openings that double as a professional entrance and natural light source when opened fully.
Hotel: Convention spaces, pool areas, or service‑wing loading docks requiring a commercial aluminum bifold door that operates smoothly for daily traffic.
Office Building: Atrium partitions or back‑of‑house receiving bays where a thermal break aluminum folding door improves energy performance and easy goods movement.
Outdoor: Semi‑exposed open‑air storage shelters; a cold storage folding door can be specified with weather‑resistant finishes and gaskets—confirm water tightness for unsheltered installations.
Residential Building: Basement garage entries or shared storage rooms where an industrial accordion door provides full opening without consuming interior swing space.
Exterior: Warehouse façades and loading dock glass doors demand wind‑resistant, sealed construction; request project‑specific design pressure data before specifying for high‑exposure walls.
Villa: High‑end residences with large indoor‑outdoor transition areas; the door’s slim profiles and hardware finishes complement luxury design while delivering industrial‑grade durability.
