Lamella slabs are generally used to form the core of structural or composite panels.

Standard rock mineral fibre in its originally produced form has excellent fire, thermal and acoustic insulation properties. For improved structural performance, the rock mineral fibre is cut and reformed into ‘lamellas’ where the fibres run perpendicular to the face of the panel, giving a product with far greater compressive strength and resistance to shear.

An open weave glass fibre reinforcement mesh is applied to both faces in order to provide structural strength to the pad whilst allowing the adhesive to form a bond between the fibres of the core and the facing used in the construction of the composite panel. Specifically designed so that the rock fibres interface with the skins of the bonded panel enabling a good adhesive take up into the structure of the rock mineral fibre and results in a high shear strength.

The slab may be supplied flat or with profiled faces on one or both sides. Edge rebate details can be machined to bespoke requirements.
