SteinWolle ALU rock wool insulation sleeve with a thickness of 40mm [040x42] /1m/ MFSR-40X042

Thermal and acoustic insulation for professionals and demanding users

SteinWolle ALU is an insulation wrap made of high-quality rock wool, covered with a layer of aluminum foil reinforced with a mesh. The product is designed for effective thermal and acoustic insulation of central heating pipelines, hot and cold water pipes, and ventilation ducts. Its versatility makes it suitable for use in residential buildings, public utility facilities, and industrial plants. Available in sections of 1 meter in length, making it easy to adapt to specific needs.

Properties and benefits

SteinWolle ALU wrap combines a number of features that translate into user comfort and installation safety:

• Effective insulation: Rock wool provides excellent thermal insulation properties, minimizing heat loss and reducing operating costs of the heating system. It also dampens sounds, improving the acoustic comfort of the rooms.
• Temperature resistance: The product withstands a medium temperature of up to +250°C, allowing it to be used in a variety of installations.
• Fire safety: Fire class A2L – s1, d0 guarantees a high level of safety in the event of a fire – it limits the spread of fire and smoke. This is an important aspect for investors and installers who care about building safety.
• Easy installation: Self-adhesive tab and a cut on one side facilitate and speed up the installation process, saving time and labor costs.
• Durability and resistance: The aluminum foil reinforced with a mesh protects the rock wool from mechanical damage and the effects of atmospheric factors, ensuring long-term protection of the installation.
• Low thermal conductivity: λ ≤ 0.037 W/(m·K) for wraps with a thickness of 20-40 mm and λ ≤ 0.038 W/(m·K) for wraps above 40 mm – ensures insulation efficiency even with a small layer thickness.

Applications and construction

SteinWolle ALU wrap is an ideal solution for:

• Insulating central heating pipes – prevents heat loss and increases the efficiency of the heating system.
• Insulating hot and cold water pipes – protects against water freezing in winter and limits water vapor condensation in summer.
• Insulating ventilation ducts – reduces noise and energy loss.
• Protecting installations in residential buildings, public utility facilities, and industrial plants.

The construction of the wrap consists of:

• A layer of rock wool – providing thermal and acoustic insulation.
• Aluminum foil reinforced with a mesh – protecting the rock wool from mechanical damage and moisture, and reflecting thermal radiation.
• Self-adhesive tab – facilitating tight installation.
• Cut on one side - allowing easy adaptation to the pipe or duct.
