PVC Frame Profile (Back Cover Profile)
What Is a Back Cover Profile in Cold Room Door Frames?
A back cover profile is the component that closes and finishes the rear side of a cold room door frame, where the frame meets the cold room wall panel. Its primary functions include:
- Covering the exposed edge of the wall panel
- Completing the frame-to-panel transition
- Providing a clean, hygienic, and professional appearance
- Supporting insulation continuity around the door opening
The PVC Frame Profile (Back Cover Profile) performs all these functions while also compensating for wall panel thickness differences, acting as an integrated frame extension profile.
Designed for Frame Profiles Without Standard Extension Compatibility
In many cold room door systems, especially those using thermally broken aluminum frames or special PVC frame geometries, standard PVC extension profiles cannot be used. This limitation commonly appears in:
- Thermally insulated aluminum door frame systems
- Economical door frame designs
- Special-profile cold room doors
The BOB-102 PVC Frame Profile (Back Cover Profile) is specifically engineered to solve this problem. Instead of relying on separate extension components, it connects directly to the main door frame profile and reaches the required wall panel thickness on its own.
Dual-Function Structure: Extension and Back Cover in One Profile
The most distinctive feature of BOB-102 is its dual-function geometry. With a single PVC profile, it performs two essential tasks simultaneously:
- Frame Extension Function
It compensates for wall panel thickness, allowing the door frame to align perfectly with the panel surface. - Back Cover Function
It closes the rear side of the frame, creating a smooth and hygienic transition between the frame and the wall panel.
By combining these functions, the PVC Frame Profile (Back Cover Profile) significantly reduces the number of components required in a door frame system.
Compatible Main Door Frame Profiles (With Product Codes)
The BOB-102 PVC Frame Profile (Back Cover Profile) is designed to work with Bob Modüler door frame profiles that do not accept standard PVC extension profiles. It is compatible with the following main frame profiles:
- BOB-101 – Thermally broken aluminum frame profile for cold room hinged doors
- BOB-106 – Thermally broken aluminum frame profile for cold room sliding doors
- BOB-10105 – Economical PVC frame profile for cold room hinged doors
- BOB-10133 – PVC frame profile without heater channel for cold room hinged doors
When used with these profiles, BOB-102 completes both the extension and back cover requirements, forming a fully integrated door frame system.
Installation Method and Working Principle
The application of the PVC Frame Profile (Back Cover Profile) is simple and efficient, making it ideal for both factory production and on-site installation:
- The main door frame profile is mounted into the prepared door opening
- The thickness of the cold room wall panel is measured
- BOB-102 is connected directly to the main frame profile
- The profile extends toward the panel surface and covers the rear side of the frame
This method ensures a continuous and stable structure where the door frame and wall panel function as a single system.
Thermal Insulation and Energy Efficiency
The junction between the door frame and the wall panel is one of the most critical points for thermal performance. The PVC Frame Profile (Back Cover Profile) improves insulation by:
- Reducing thermal bridges at the frame-to-panel interface
- Limiting cold air transfer through the door frame
- Supporting stable internal temperatures inside the cold room
PVC’s low thermal conductivity plays a key role in maintaining energy efficiency, especially in industrial cold storage environments.
Hygienic and Durable PVC Structure
The PVC material used in BOB-102 offers several advantages for cold room applications:
- Resistant to moisture and condensation
- Corrosion-free and long-lasting
- Easy to clean and hygienic
- Suitable for food storage and pharmaceutical cold rooms
These properties ensure reliable performance over the entire service life of the door frame.
Economical and Practical Door Frame Solution
By replacing multiple components with a single profile, BOB-102 PVC Frame Profile (Back Cover Profile) delivers significant economic and operational benefits:
- Reduced material costs
- Shorter installation time
- Fewer components and assembly steps
- Lower risk of installation errors
This makes it an ideal choice for cost-optimized cold room door frame systems without compromising performance.
