Aluminum Frame Profile (Thermal Break Type)
What Is a Thermal Break Aluminum Frame Profile?
A thermal break aluminum frame profile is designed to minimize heat transfer between the cold room interior and the external environment. BOB-106 achieves this by integrating two different materials within one profile using co-extrusion technology.
In this structure:
- The outer section of the frame, located outside the cold room, is made of anodized aluminum
- The inner section of the frame, exposed to the cold room interior, is made of PVC
This combination creates an effective thermal barrier that prevents cold air inside the cold room from being transferred to the aluminum exterior, significantly reducing thermal bridging.
Advantages of the Co-Ex Structure in Sliding Door Systems
Cold room sliding doors typically have larger surface areas than hinged doors, which can increase the risk of heat loss if the frame system is not properly insulated. The co-ex structure of the BOB-106 Aluminum Frame Profile addresses this challenge effectively.
Key advantages include:
- Reduced thermal bridging between interior and exterior surfaces
- Improved energy efficiency of the cold storage facility
- Lower risk of condensation and frosting on the frame
- Stable insulation performance over long periods of use
These features make BOB-106 an ideal solution for modern cold room sliding door installations.
Application in Cold Room Sliding Door Frames
The BOB-106 Aluminum Frame Profile is designed exclusively for use in cold room sliding door frames, including:
- Cold room sliding doors
- Cold room monorail sliding doors
- Cold room automatic sliding doors
In sliding door systems, precise frame geometry is essential to ensure smooth door movement and proper alignment with the rail and carrier mechanisms. BOB-106 provides the dimensional stability and mechanical strength required for these systems.
With this profile:
- The door leaf moves smoothly along the rail system
- Gaskets compress evenly against the frame
- Air leakage is minimized
- Long-term operational reliability is ensured
Integrated Heating Cable Channel for Freeze Protection
One of the key functional features of the BOB-106 Aluminum Frame Profile is the presence of an integrated heating cable channel located in the gasket contact area.
Sliding door systems are particularly vulnerable to freezing at the frame–gasket interface, especially in low-temperature cold rooms. To prevent this issue:
- A highly conductive aluminum heating cable cover profile (BOB-10001) is installed over the channel
This design ensures:
- Even heat distribution along the sealing line
- Prevention of ice formation
- Reliable door operation under extreme cold conditions
The heating cable system significantly improves operational safety and user comfort in freezer and deep-freeze applications.
Frame Structure Without Extension Profiles
Unlike modular PVC frame systems, the BOB-106 Aluminum Frame Profile does not require extension profiles to adapt to wall panel thickness.
Instead, frame completion is achieved using one of the following methods:
- PVC Panel Closing Profile (BOB-102)
- Metal sheet bending, shaped according to the geometry of BOB-102
This approach offers several advantages:
- A simpler and more rigid frame structure
- Fewer components during installation
- Faster assembly time
- Reduced risk of installation errors
As a result, the frame becomes stronger, cleaner in appearance, and more durable.
Durability and Long Service Life
Thanks to its aluminum–PVC co-ex structure, the BOB-106 Aluminum Frame Profile significantly enhances the durability of cold room sliding door frames.
- The anodized aluminum exterior provides excellent resistance to impacts, corrosion, and mechanical wear
- The PVC interior section supports thermal insulation and hygiene
- The overall structure maintains stability even under intensive use
This makes BOB-106 suitable for industrial cold storage environments with high operational demands.
Material Synergy: Aluminum and PVC
The combination of aluminum and PVC within a single profile offers optimal performance:
- Aluminum provides strength, rigidity, and precise geometry
- PVC acts as a thermal insulator and reduces heat transfer
- Both materials are resistant to moisture and condensation
- The profile is hygienic and easy to clean
This synergy forms the foundation of the thermal break performance of BOB-106.
