Description
Duct rubber insulation is used on supply air ducts, return air ducts, cold duct branches, and indoor air-conditioning routes when the site needs heat, fire, sound, or condensation control in a controlled layer. The product has to follow real edges and support points, so duct surface anti-condensation is checked before packing. The final supply is based on sheet thickness and width by duct size and humidity, the required surface, and the method used to close seams.

Product Advantages
Duct rubber insulation is useful when the route has limited space because the order can be arranged by actual thickness and installation clearance.
Matching facing and seam treatment helps keep the outer layer cleaner in handover photos and later inspection.
The product can be grouped with tape, covers, or support parts when the order list requires them.
Certifications & Qualifications
For duct rubber insulation, use the Rubber Plastic Sheet certificate when the duct surface is covered with rubber plastic sheet material.
Product conformity document: UDEM Technical Inspection Attestation of Conformity for Rubber Plastic Sheet, related standard EN 14304:2015, certificate No. M.2025.206.C125163, report No. TCF-OY20250812-EN-04.
Certificate model: Xinyafeng/800*1500*25mm. Duct width, sheet thickness, adhesive or facing request, and packing marks should be checked before loading.
Company ISO certificates can be supplied separately when needed, while the product conformity certificate should follow the rubber plastic sheet file.
TDS, MSDS, certificate image, packing list, and customs documents can be prepared for the duct insulation order.
