Type of Material: It is a Glass Mineral Wool slab. This indicates it's made from spun glass fibers, a common and effective material for thermal insulation.
Thickness: The "150mm" specifies its thickness, which is a significant dimension for insulation, directly impacting its thermal performance.
Water-Repellent: This is a crucial feature for cavity wall insulation. Being water-repellent means it resists the passage of moisture, preventing the insulation from becoming saturated and losing its thermal effectiveness, which is vital in external walls exposed to rain and dampness.
Application: Designed for use in external full-fill masonry cavity walls. This means it's intended to completely fill the cavity (the gap between the two leaves of a masonry wall) to maximize thermal efficiency.
Thermal Performance: It "offers the best thermal performance in the range." This suggests it has a very low lambda value (thermal conductivity), meaning it's highly effective at reducing heat transfer through the wall, contributing to better energy efficiency and lower heating costs for the building.
Non-Combustible with Euroclass A1 Reaction to Fire Classification: This is a top-tier safety feature.
Non-combustible: The material itself will not burn.
Euroclass A1: This is the highest possible fire safety rating under the European classification system (EN 13501-1). It signifies that the product contributes absolutely no fuel to a fire and produces virtually no smoke or flaming droplets, making it incredibly safe for building occupants and structures.
 
In summary, the 150mm DriTherm Cavity Slab 32 is a high-performance, safe, and durable insulation solution specifically engineered for the challenging environment of external masonry cavity walls, providing excellent thermal efficiency and superior fire protection.
