Features & Benefits

Maximum Fire Protection

Jamofire™ is the only sliding cold storage door that defends against fire and separates climates in one seamless solution. 

Excellent Thermal Separation

Engineered to withstand subzero conditions without sacrificing insulation integrity, even in freezers and high-demand environments. 

Automatic, Power-Free Closure

A gravity-guided system with fusible link counterweight seals the door during fire. No electricity or human intervention needed, no second guessing.

Article information

Most fire doors can't handle subzero conditions, forcing cold storage facilities to choose between fire safety and thermal performance. 

With Jamofire™, facility managers don't have to compromise. This fire-rated sliding door delivers both reliable protection and effective environment separation. 

Why Fire Sliding Doors Are Critical 

In tightly sealed spaces, heat and smoke can spread quickly, turning a minor spark into a major risk. With so much at stake, cold storage facilities need a solution that goes beyond basic compliance. 

Jamison Door designed the Jamofire™ as a 3-hour fire-rated door to meet specific cold storage needs. Formerly called the Firetemp door, Jamofire™ sliding door protects staff and inventory. 

Heavy-Duty Insulation That Works Overtime 

Jamofire™’s fire-resistant insulation maintains thermal stability in harsh, low-temperature environments. It forms a critical barrier that blocks flames, smoke, and heat. 

Specifications

*If cold room temperature is less than -20° F on back, Jamofire™ door cannot be used. Maximum temperature differential front to back is 60° F.  

Fire-Resistant Insulation

Jamison fills sliding fire doors with 4-inches of specially formulated insulation. This fire-resistant thermal barrier provides an R-value of 17 at 40°F. That means better protection for your inventory, energy efficiency, and more time to respond in an emergency. 

Gravity-Guided "Down and In" Movement

To ensure superior sealing, Jamofire® features a gravity-guided "down and in" movement. This enables seals to tightly press against the door opening. Expertly preventing the spread of flames, smoke, and heat while maintaining cold storage efficiency. 

Flexible for Demanding Applications

Jamofire™ commercial fire rated doors keep flexibility in mind. Door options include stainless-steel cladding for added durability. Padlocking provisions with interior safety releases are available for increased security. Jamison can modify doors to meet M.I.D. (Marine Insulation Door) standards. 

Where Fire Safety and Cold Storage Converge

Jamofire™ bridges the gap between strict fire codes and cold chain consistency. In food processing plants, it meets strict fire safety regulations, protecting both workers and inventory without disrupting operations. With #26-gauge steel doors and frames, Jamofire™ is just as sharp in appearance as it is strong in performance. 

Fire Doesn’t Wait. Neither Should Your Door. 

In cold storage, insulation holds in cold but when fire strikes it also traps heat and smoke. Jamofire™ sliding doors are the ideal cooler or freezer door to stop flames in their tracks. It meets tough fire codes without compromising cold chain integrity. 

Fire-rated Freezer Doors 

Jamofire™ performs where most doors fail: in freezing, high-risk environments. Its fully sealed warm-side metal cladding blocks air leaks and stands up to extreme conditions. The system uses heater cables on all sides to prevent frost buildup in freezing conditions. This keeps the door operating smoothly even in deep freeze. 

Hot Threats. Cold Conditions. One Trusted Door.

Cold Storage 

Fire-rated sliding doors are essential at key separation points within cold storage facilities. This can be between freezer rooms, staging areas, and corridors to contain fire and prevent heat and smoke from spreading.  

Food Processing 

In food processing plants, fire risks come from electrical equipment, thermal processing zones, and flammable packaging materials. Heavy use doors provide barriers that support both sanitation protocols and emergency preparedness. 

Temperature-Controlled Logistics & Distribution 

Distribution centers handling perishable goods must operate across multiple temperature zones. From refrigerated docks to deep freezer zones, fire-rated doors help maintain stable temps and meet fire regulations.
