StP Bromo Sound Insulation 7mm – 2-in-1 Sound Blocking & Absorption Material Australia Looking for a single material that both blocks and absorbs sound inside your car? StP Bromo i s a high-performance car sound insulation material that combines a dense sound barrier and an acoustic absorption layer in one sheet — delivering powerful noise reduction with faster installation. This makes it one of the most efficient sound deadening solutions in Australia. What Is StP Bromo? StP Bromo is a multi-layer sound insulation material designed to reduce both airborne noise and low-frequency vibrations. It combines two essential functions: Sound blocking (mass layer) Sound absorption (foam layer) This eliminates the need for multiple materials and simplifies installation. Why 2-in-1 Soundproofing Matters In a traditional setup, you would need: One layer to block sound Another layer to absorb sound StP Bromo combines both in one sheet, which means: Faster installation Cleaner results Less weight compared to multiple layers How Much Coverage Do You Get? One pack (10 sheets, 1.76 m² total coverage) is enough to: Insulate the entire cabin floor and boot, or Treat rear wheel arches and under-seat areas for deeper noise reduction Ideal for floor sound deadening and cabin insulation. Where to Use StP Bromo Floor (main road noise source) Boot / trunk area Rear wheel arches (interior side) Under seats Spare wheel well Best applied on top of a vibration damping layer (StP Gold or Aero). Why StP Bromo Works Multi-layer construction: heavy butyl membrane + perforated foam + protective cover Blocks and absorbs sound (mid + low frequencies) Reduces installation time vs multi-layer systems Strong adhesion to damping layers and metal Designed for harsh cabin and boot conditions This makes it one of the most effective floor sound insulation materials. Performance Benefits Reduces road and tyre noise Improves cabin quietness on highways Enhances overall driving comfort Improves audio system clarity Installation Guide Clean and degrease the surface Install vibration damping layer first Cut Bromo sheets to size Peel backing and press firmly Use roller for tight areas Simple and efficient installation for both DIY and professional use.
