Urbanization intensifies demand for effective noise insulation panels. Our 2-inch acoustic isolation boards utilize mass-loaded vinyl cores sandwiched between rigid foam insulation layers, achieving 30% better STC ratings than standard drywall alternatives. The 50mm soundproof insulation board variant is particularly popular for apartment conversions, blocking 98% of airborne noise while serving as thermal barriers. Clients from Dubai to Berlin use our isolation board systems to create silent offices, home theaters, and healthcare facilities. With optional fire-retardant coatings and custom sheet insulation board sizes, we enable architects to meet both acoustic regulations and energy codes in one installation.
