Compressed Cork Insulation Sheets
These are rigid sheets made from compressed agglomerated cork particles, often used for thermal and acoustic insulation in walls and roofs. They fall under HTS 4504.10.20.00 as they are specifically classified as insulation products from compressed cork, coated or not. The material's natural properties provide excellent sound absorption and heat resistance.
Coated Compressed Cork Wall Insulation Panels
Pre-cut panels of compressed cork with a protective coating, ideal for interior wall insulation in residential and commercial buildings. Classified under HTS 4504.10.20.00 due to their compressed cork composition and primary function as thermal insulation. The coating enhances moisture resistance without altering the base classification.
Uncoated Compressed Cork Acoustic Insulation Boards
Dense boards manufactured from compressed cork granules for superior soundproofing in studios and theaters. They qualify for HTS 4504.10.20.00 as uncoated insulation made from agglomerated compressed cork. Their porous structure effectively dampens noise vibrations.
Compressed Cork Roof Insulation Strips
Narrow strips of compressed agglomerated cork designed for under-roof thermal insulation in construction. Falls under HTS 4504.10.20.00 as strip-form insulation from compressed cork, suitable for both coated and uncoated variants. Provides natural fire resistance and sustainability.
Fire-Resistant Coated Cork Insulation Disks
Solid cylindrical disks of compressed cork with intumescent coating for pipe insulation and fire barriers. Classified in HTS 4504.10.20.00 as insulation disks explicitly covered under compressed cork provisions. The coating activates in high heat for added safety.
