Izowool Rock Wool Lamella Mat | Flexible Insulation for Curved and Cylindrical Surfaces

Izowool Rock Wool Lamella Mat

Izowool Rock Wool Lamella Mat is a high-performance insulation solution designed for pipes, tanks, ducts, and curved surfaces. Manufactured from premium-quality stone wool, it combines excellent thermal insulation, fire resistance, and acoustic performance in a flexible roll format. Its A1 non-combustible classification makes it a reliable choice for projects where fire safety and long-term durability are essential. It is widely used in industrial facilities, HVAC systems, and mechanical installations.

Product Description

Izowool Rock Wool Lamella Mat is produced by cutting stone wool boards into narrow strips and bonding them onto a glass tissue facing or aluminum foil facing. The fibers are positioned perpendicular to the surface, providing outstanding flexibility and allowing the insulation to conform easily to cylindrical, curved, or irregular surfaces.

Its roll format ensures quick installation while maintaining consistent insulation thickness across the entire application area.

Key Features

  • Vertical Fiber Structure: Maintains its shape without sagging or losing thickness over time.
  • Flexible Roll Design: Easily adapts to pipes, tanks, ducts, and curved or inclined surfaces.
  • Moisture Resistance: Provides long-lasting insulation performance while helping protect against moisture penetration.
  • Fire Safety: Classified as A1 non-combustible; does not contribute to fire spread and produces no toxic gases during fire exposure.
  • Maximum Service Temperature: Suitable for continuous operating temperatures up to 250°C.
  • Melting Temperature: Above 1000°C, providing excellent fire resistance.

Applications

Izowool Rock Wool Lamella Mat is suitable for a wide range of insulation applications, including:

  • Pipe insulation
  • Tanks and storage vessels
  • Boilers and chimneys
  • Curved and inclined surfaces
  • Industrial mechanical installations
  • HVAC systems (heating, ventilation, and air conditioning)
  • Thermal and acoustic insulation for process equipment

Installation Guidelines

The insulation mat is wrapped around the surface to be insulated and secured using appropriate fixing materials depending on the facing type.

  • Glass Tissue Facing: Recommended where additional mechanical strength is required.
  • Aluminum Foil Facing: Ideal for applications requiring an effective vapor barrier.

Proper installation with tight joints and complete surface coverage is essential for achieving optimum thermal and acoustic performance.
