Aluminum Frame Profile (Thermal Break Type) – BOB-101

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 cold and warm environments by integrating materials with different thermal properties. BOB-101 features a co-extruded (co-ex) structure, combining aluminum and PVC within the same profile.

In this design:

• The outer side of the frame, located outside the cold room, is made of anodized aluminum
• The inner side of the frame, exposed to the cold room interior, is made of PVC

This co-ex structure forms an effective thermal barrier, preventing cold air inside the cold room from being transferred to the exterior aluminum surface.

Advantages of the Co-Ex Structure

The co-ex structure of the BOB-101 Aluminum Frame Profile provides significant advantages over conventional aluminum frame systems:

• PVC acts as a thermal insulator, reducing heat transfer
• Aluminum provides high mechanical strength and impact resistance
• Thermal bridges are effectively minimized
• Condensation and frosting risks on the external frame surface are reduced
• Energy efficiency of the cold room is improved

This combination makes BOB-101 an ideal solution for modern cold room hinged door installations.

Application in Cold Room Hinged Door Frames

The BOB-101 Aluminum Frame Profile is designed exclusively for use in cold room hinged door frames. Hinged doors transfer all operational loads—such as door weight and opening forces—directly to the frame through the hinges. Therefore, frame rigidity and dimensional stability are essential.

By using BOB-101, cold room hinged doors benefit from:

• Strong and stable hinge mounting points
• Accurate door alignment
• Consistent gasket compression
• Reduced air leakage
• Long-term structural reliability

These properties contribute directly to the performance and service life of the door system.

Integrated Heating Cable Channel

One of the key functional features of the BOB-101 Aluminum Frame Profile is the presence of a heating cable (resistance cable) channel located at the gasket contact area.

This channel is designed to prevent freezing in critical sealing zones. To optimize heat distribution:

• A highly conductive aluminum cover profile (BOB-10001) is installed over the heating cable channel

This configuration ensures:

• Uniform heat transfer along the gasket line
• Prevention of ice formation between the door leaf and the frame
• Reliable door operation even at very low temperatures

The heating cable system is especially important in freezer rooms and deep cold storage applications.

Frame Structure Without Extension Profiles

Unlike modular PVC frame systems, the BOB-101 Aluminum Frame Profile does not use extension profiles. Instead, frame depth adaptation is achieved using alternative solutions.

To match the wall panel thickness, one of the following methods is applied:

1. PVC Panel Closing Profile – BOB-102
2. 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 in the frame system
• Faster installation
• Reduced risk of assembly errors

As a result, the frame becomes stronger and more durable.

Strength and Long-Term Durability

Thanks to its aluminum–PVC co-ex structure, the BOB-101 Aluminum Frame Profile significantly enhances the durability of cold room hinged door frames.

• The anodized aluminum exterior resists impacts, corrosion, and mechanical wear
• The PVC interior maintains insulation performance and hygiene
• The overall frame structure remains stable over long service periods

This design makes BOB-101 particularly suitable for high-traffic cold storage facilities.

Advantages of Aluminum and PVC Combination

The combination of aluminum and PVC in a single frame profile offers the best of both materials:

• Aluminum ensures structural strength and dimensional accuracy
• PVC reduces thermal conductivity and improves insulation
• Both materials are resistant to moisture and condensation
• The profile is easy to clean and hygienic

This synergy is the foundation of the thermal break performance of BOB-101.
