Overview
When cold storage warehouses and temperature-sensitive facilities need flexible thermal separation without permanent construction, insulated curtain walls deliver. These modular panel systems create distinct temperature zones — from freezer-to-freezer, cooler-to-ambient, and everything in between — while keeping energy costs under control and floor plans adaptable.
Barron Equipment supplies the Chase Doors FlexTherm® line of insulated curtain walls, engineered specifically for temperature zoning in cold storage warehouses, distribution centers, food processing facilities, manufacturing plants, and data centers. Whether you need to partition a refrigerated area from an ambient workspace or reconfigure a room for seasonal demands, this insulated curtain wall system installs quickly, requires no building permits, and avoids costly facility shutdowns.
Two models are available to match your temperature separation requirements. FlexTherm® I provides an R-Value of 9.5 using dual-layer AstroFoil insulation for higher-demand environments. FlexTherm® II offers an R-Value of 5.0 with single-layer AstroFoil II insulation for moderate temperature zoning applications. Both models feature NFPA 701 fire rated vinyl shells and ASTM-E-84 rated laminated bubble foil insulation, meeting the fire rating standards required in commercial and industrial settings.
Temperature Control and Energy Savings
Curtain wall insulation is one of the most cost-effective methods for managing temperature separation across large facilities. Rather than investing in permanent wall construction, insulated curtain walls allow operations to isolate heated, cooled, or refrigerated zones with minimal disruption.
Each 61-inch-wide panel connects to adjacent panels using full-height Velcro closures, forming a continuous thermal barrier. An adjustable floor sweep along the bottom of each panel seals the wall to the floor, preventing cold air loss and reducing energy consumption. The result is reduced energy spend, more consistent temperatures in each zone, and less strain on HVAC and refrigeration systems.
Facilities that manage cold storage warehouses, blast freezer staging areas, or temperature-sensitive production lines benefit the most from a temperature control curtain wall. By containing conditioned air within defined zones, businesses can reduce energy waste and maintain product integrity throughout the supply chain.
Construction and Fire Rating
Every panel is built with a heavy-duty reinforced vinyl shell designed for the rigors of industrial environments. The laminated bubble foil insulation core — AstroFoil — provides high thermal resistance while keeping each panel lightweight at just 0.31 to 0.35 lbs. per square foot.
Seams on the top and bottom edges are folded over to protect against moisture intrusion and sewn with moisture- and UV-resistant thread. Double-needle stitching is back-tacked on the bottom and sides of each panel to prevent unraveling over time. Grommets across the top of every panel allow for straightforward mounting to existing support structures, and panels can be cut on-site to accommodate openings, obstacles, or penetrations using included patch kits.
The fire rating on these thermal curtains meets both NFPA 701 and ASTM-E-84 standards, making them suitable for environments where fire safety compliance is required. This combination of durable construction, fire rating certification, and high quality materials ensures long service life even in demanding cold storage and warehouse settings.
Applications
Insulated curtain walls are commonly deployed in facilities where flexible temperature zoning is essential. Typical applications include cold storage warehouses, food processing and packaging plants, refrigerated distribution centers, pharmaceutical storage areas, manufacturing facilities with climate-sensitive materials, and data centers requiring environmental control. They are also used in seasonal storage operations where room configurations change based on inventory volume or product requirements.
Optional accessories expand the functionality of any installation. Free-standing door frames can be integrated into curtain openings for foot traffic. Strip doors, swinging doors, air curtains, and roll-up vinyl doors can all be added to the curtain wall layout, enabling seamless personnel and equipment access while maintaining temperature separation between zones.
Installation and Maintenance
One of the strongest advantages of an insulated curtain wall system over traditional construction is the speed and simplicity of installation. Panels mount directly to existing overhead structures using grommets — no building permits, structural modifications, or facility shutdowns are required. For operations that cannot afford downtime, this is a critical benefit.
Ongoing maintenance is equally straightforward. Panels are easy to clean with mild detergent and water, and individual sections can be repaired or replaced without disassembling the entire wall. Inspect floor sweeps and Velcro closures periodically for wear, and check grommets and support points to ensure panels remain securely mounted and properly aligned.
