Product Description

Thermal Insulation Rock Wool Lamella – Exterior Wall Insulation

Product Overview

Our Class A1 non-combustible insulation rock wool lamella is engineered for external wall insulation systems of high-rise buildings and Passive Houses. Made from high-quality basalt and processed into strip form, it meets the highest national standard for non-combustible materials (Class A1). This product offers customizable thickness, easy installation, excellent fire resistance, and superior energy efficiency.

Applications

Exterior wall insulation for high-rise and super-high-rise buildings
Passive house and near-zero energy building insulation
Projects with tight construction schedules
Public buildings (hospitals, schools, shopping malls, etc.)
Retrofitting and energy-saving renovation projects

Key Features & Advantages

Custom Thickness

Available in various thicknesses to meet strict insulation demands of passive houses and near-zero energy buildings, adapting flexibly to different energy standards.

Easy and Fast Installation

Installed directly with ordinary cement mortar—no complex mechanical fixings required—ensuring high installation efficiency, shorter construction time, and lower labor costs.

Class A1 Non-Combustible

Meets Class A1 non-combustible material standard: does not burn, contribute to fire, or propagate flames, providing reliable fire protection for buildings.

Excellent Energy Efficiency

Dense fiber structure ensures low thermal conductivity and stable insulation performance, effectively reducing building energy consumption and meeting energy efficiency standards.
