Product Overview
Full-fill glass mineral wool insulation slab, measuring 150mm in thickness, for use in masonry cavity walls.
Manufactured with a high recycled glass content and ECOSE® Technology, it delivers advanced thermal insulation while remaining vapour permeable, helping the wall construction to breathe.
With a thermal conductivity of 0.032 W/mK, it provides superior energy efficiency, enabling lower U-values to be achieved at reduced insulation thicknesses.
Rated Euroclass A1 non-combustible and fully BBA certified for all UK exposure zones, it ensures proven fire safety, durability, and long-term reliability.
At 150mm thick, the largest slab in the DriTherm 32 range, it is designed for wider cavity walls in new build housing.
This depth provides the highest level of thermal performance, helping developments meet stricter Building Regulation requirements while allowing full-fill installation in a single layer for easier, faster fitting.
Features & Benefits
- Non-combustible Euroclass A1 fire rating: Ensures maximum fire safety in external walls.
- Thermal conductivity 0.032 W/mK: Outstanding insulation efficiency for extra-wide cavities.
- Water-repellent additive: Stops moisture transfer while staying vapour permeable.
- 455mm width: Fits standard wall tie spacing for a close jointed finish.
- Slabs knit together: Prevents air gaps and reduces thermal bridging.
- Lightweight and cuttable: Simple handling and fitting on site.
- ECOSE® Technology binder: No added formaldehyde and reduced embodied energy.
- 150mm thickness: Suited to wide cavity wall constructions, providing the highest level of thermal performance in the DriTherm 32 range.
Applications
- Extra-wide cavity walls (150mm): Suited to low-energy and advanced housing.
- High-performance housing: Provides maximum insulation efficiency.
- Masonry cavity external walls: Reliable, fire-safe insulation for large cavity depths.
- Sustainable builds: Supports ultra-low U-values and future-ready housing.
Installation Guidance
- Cut to fit: Slabs can be trimmed cleanly with a sharp knife for an accurate fit.
- Close-butt joints: Ensure slabs are tightly butted together with no gaps to maintain insulation performance.
- Keep dry before fitting: Store indoors or under cover to protect the slabs until installation.
Compliance & Performance
- Euroclass A1 to BS EN 13501-1: Highest level of non-combustibility.
- BBA certified for all exposure zones: Approved for UK use in severe weather locations.
