WHAT IT IS

Glass Wool (Fibreglass) Roof Insulation is a lightweight thermal and acoustic insulation manufactured from recycled glass fibres, used for roofs and ceilings in Malaysian residential and commercial buildings. Classified under HS 7019801000, import duty 20%, SST 10%. Produced to MS 1020, density 8–24 kg/m³, thermal conductivity λ ≈ 0.030–0.038 W/m·K. Available foil-faced (aluminium foil acts as a radiant barrier) or unfaced; roll width 1.2 m, lengths 10–20 m, thickness 25–75 mm. Lower density than rock wool and slightly lower cost; sensitive to moisture if face is damaged. Foil-faced variants are common in Malaysia's tropical climate where radiant heat reduction is a primary driver of roof insulation selection.

OFFICIAL DESCRIPTION Glass wool

IMPORT DUTY (MFN) 20%

SST 10%

Sourced from PDK 2025 (Customs Duties Order 2025). The import duty shown is the MFN / general rate — preferential rates under FTAs (ATIGA, ACFTA, etc.) are typically lower or zero. SST per the PDK 2025 schedule (a value like 10%/0% means standard/exempt variants). Indicative only — confirm the applicable rate and tax treatment with your licensed customs/tax agent before relying on it. Spotted an error? hello@ttkbuildingmaterials.com
