Rockwool Ductwrap Insulation – Thermal & Acoustic Insulation for HVAC Ducts, Tanks & Pipes Optimize your HVAC and plumbing systems with Rockwool Ductwrap Insulation, a high-performance mineral wool insulation roll designed for thermal, acoustic, and fire protection. Available at Pipelagging.com, this lightweight, flexible roll, faced with reinforced aluminium foil, comes in 25mm, 40mm, and 50mm thicknesses, making it ideal for insulating circular, square, and rectangular ductwork, as well as water tanks and pipes with service temperatures up to 230°C. Rockwool Ductwrap reduces heat loss, prevents condensation, and provides excellent fire safety, ensuring energy efficiency and durability in both residential and commercial applications across the UK. Key Features & Benefits: Excellent Thermal Insulation: With a thermal conductivity of 0.035 W/(m·K) at 50°C, Rockwool Ductwrap minimizes heat loss, improving energy efficiency in HVAC systems, water tanks, and pipework, potentially reducing energy costs by up to 20% in well-insulated systems. A1 Non-Combustible Fire Safety: Rated A1 non-combustible (EN 13501-1), this insulation offers the highest level of fire resistance, preventing the spread of flames and smoke, making it a safe choice for buildings like schools, hospitals, and offices. Effective Condensation Control: The reinforced aluminium foil facing acts as a vapour barrier, preventing condensation on chilled ductwork and pipes, protecting against corrosion and maintaining system integrity in humid environments. Water-Repellent Design: Rockwool Ductwrap repels liquid water while allowing moisture vapour to pass through, ensuring durability in damp conditions without compromising insulation performance. Superior Acoustic Performance: The dense mineral wool structure absorbs sound, reducing noise from air movement in ductwork or high-velocity fluids, ideal for noise-sensitive environments like educational and healthcare facilities. Lightweight & Easy to Install: This flexible insulation roll is easy to cut and wrap around ductwork, tanks, and pipes, ensuring a snug fit for various shapes and sizes, saving time and effort during installation. High-Temperature Resistance: Suitable for service temperatures up to 230°C, making it perfect for warm air ductwork, hot water pipes, and heating systems in both domestic and commercial settings. Sustainable & Durable: Made from natural stone and up to 97% recyclable materials, Rockwool Ductwrap is environmentally friendly and designed to last the lifetime of the building without special maintenance. Regulatory Compliance: Authorized for use in London Underground (LUL) surface and sub-surface premises (LUL Ref: 315) and complies with BS 5422 for thermal insulation requirements. Applications: Rockwool Ductwrap Insulation is primarily suited for thermal and acoustic insulation of circular, square, and rectangular HVAC ductwork, as well as cold water storage, feed, and expansion tanks in residential, commercial, and industrial settings. It’s ideal for air conditioning, warm air, and extractor ducts located in plant rooms, boiler houses, or externally, as well as hot water pipes and heating systems. The insulation meets regulatory thermal requirements and prevents condensation on chilled ductwork, making it suitable for schools, hospitals, offices, and homes. Its acoustic absorption properties also make it perfect for ducts carrying gases, fluids, or particle solids at high velocities, enhancing workplace comfort and productivity. Technical Specifications: Material: Mineral wool (stone wool) with reinforced aluminium foil facing. Thickness Options: 25mm, 40mm, 50mm. Roll Dimensions: 1m wide, with lengths varying by thickness (e.g., 6m for 25mm, 5m for 40mm, 4m for 50mm). Thermal Conductivity: 0.035 W/(m·K) at 50°C. Fire Rating: A1 non-combustible (EN 13501-1). Maximum Service Temperature: 230°C. Water Vapor Resistance: Approximately 1000 MNs/g (foil facing). Nominal Density: 45 kg/m³. Environmental Impact: 97% recyclable, made from natural stone and recycled materials, zero ODP and GWP. Compliance: Meets BS 5422 and authorized for LUL premises (LUL Ref: 315). Why Choose Rockwool Ductwrap Insulation? Rockwool Ductwrap Insulation offers a robust combination of thermal efficiency, fire safety, and acoustic performance, making it a trusted choice for HVAC and plumbing professionals.
