Cork Rolls

Cork roll and cork backing differ in terms of production process, application and properties. Here are the detailed differences between them:

Cork roll
Production:

Raw material:

Natural cork: Cork rolls are usually made of natural cork obtained from the bark of the cork oak tree. Whole pieces of cork or finely ground cork particles are used.
Manufacturing process:

Gluing and pressing: Natural cork or its granules are mixed with glue and pressed into rolls. This process involves heating and pressing to obtain a uniform cork structure in the form of a roll.
Processing and Cutting: Once the cork rolls are manufactured, they may undergo further processing such as cutting to appropriate sizes and shapes. Cork rolls can also be covered with a protective layer or dyed.
Finish:

Surface: Cork rolls can have a variety of surfaces, from smooth to structured, depending on the application. They are often used for wall decoration or as surfaces for attaching notes.
Application:

Wall decoration: Cork rolls can be used for wall finishing, creating cork wallpapers or decorative panels.
Work surfaces: Used on bulletin boards and in offices for pinning notes.
Cork underlay
Production:

Raw material:

Cork granules: Cork underlayment is often made from cork granules or flattened cork shavings, which are mixed with glue and processed into slabs or mats.
Manufacturing process:

Extraction and pressing: Cork granulates are pressed into plates under high pressure. This process ensures the appropriate density and structure of the cork underlay.
Gluing and curing: After the boards are formed, they are hardened and glued to obtain a stable and durable structure. Cork underlayment may also undergo additional processes such as lamination to improve its insulating properties and moisture resistance.
Finish:

Surface: The cork base is usually covered with an additional protective layer or processed to make it more resistant to moisture and mechanical damage.
Application:

Thermal and acoustic insulation: Cork underlay is used as thermal and acoustic insulation under various types of floors, such as panels, ceramic tiles or carpets.
Wall Insulation: Can be used to insulate walls to improve building energy efficiency and soundproofing.
Key Differences:
Raw material type:

Cork rolls: They mainly use whole pieces of cork or cork granules that are pressed into a roll. They often have an aesthetic appearance and are used in decoration.
Cork underlay: Produced from cork granules or shavings, which are pressed and glued into boards. Focused on insulating functionality.
Manufacturing process:

Cork rolls: The process involves gluing and pressing into a roll and then further processing to obtain the desired appearance.
Cork underlay: The manufacturing process involves pressing cork granules into boards or mats, often with additional protective layers.
Application:

Cork rolls: Mainly used for decoration, bulletin boards, wallpaper, and work surfaces.
Cork underlay: Mainly used as an insulating material for floors and walls, improving energy efficiency and acoustics.
Features:

Cork rolls: Aesthetic, less focused on insulation.
Cork underlay: High functionality in terms of thermal and acoustic insulation.
Examples of manufacturers and products:
Cork rolls:

Amorim Cork Composites: A company offering various types of cork, including cork rolls for interior decoration and finishing.
Corksribas: Manufacturer offering cork rolls in various variants for decorative applications.
Cork backing:

Jelinek Cork: Specializes in the production of cork underlays with insulating properties.
Tarkett: Manufacturer offering cork floor underlays that improve comfort and energy efficiency.
In summary, cork rolls and cork backing differ in both production and application. Cork rolls are more focused on aesthetics and decoration, while cork backing focuses on insulating and protective properties.
