5. Installation Guidelines
Construction Overview Featuring soft texture and excellent flexibility, rubber plastic boards support diverse construction methods including surface paving, interlayer filling, equipment wrapping, wall sound insulation bedding and pipeline cladding. The material can be directly bonded to boards, air ducts and equipment surfaces with dedicated adhesive. Self-adhesive options are available for faster installation on flat surfaces and regular pipelines. The entire process requires no heavy machinery, suitable for both new construction and renovation projects.
Key Installation Precautions Substrate Treatment: Ensure construction surfaces are dry, dust-free and oil-free to guarantee firm adhesion, avoid warping or detachment, and maintain complete thermal insulation and airtight performance. Splicing & Lapping: Adopt staggered lapping for board joints with tight fitting. Fill all gaps with professional sealant to prevent cold leakage and sound penetration and enhance overall airtightness. Moisture Protection: For long-term outdoor, high-humidity and condensation-prone environments, additional waterproof layers or aluminum foil facing are recommended to upgrade weather resistance and waterproof durability.
