EXTERNAL WALL INSULATION SYSTEMS /
LAMELLA SYSTEM
The PermaRock Lamella System is an advanced EWI composite system based on fire safe mineral fibre (Rockwool) lamella insulation.
PermaRock Lamella Insulation boards have the mineral wool fibres oriented perpendicular to the wall surface, an arrangement that enables the insulation boards to be adhesively bonded to the wall using our high bond strength Lamella Adhesive.
This combination produces a high tensile strength system that can not only be applied to flat wall areas but which is also ideally suited for application onto tightly radiused concave or convex curved surfaces.
In most cases, the use of additional mechanical fixings may be unnecessary as the high bond and high tensile strength of this composite system is sufficient to withstand very high levels of wind suction forces.
The PermaRock Lamella System offers a number of key advantages:
- High performance PermaRock Lamella insulation boards from 30 mm to 300 mm thick.
- Adhesive-only bonding.
- Tightly radiused curves can be created.
- Lamella insulation boards can be rasped to give very flat surfaces.
- Engineered design for solid wall, timber frame or metal frame constructions.
- Free from CFCs and HCFCs. Zero ozone depletion potential (ODP).
