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 structure 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. A highquality durable adhesive specifically designed for this purpose is essential to ensure satisfactory overall performance.
The slab may be supplied flat or with profiled faces on one or both sides.
Edge rebate details can be machined to bespoke requirements.
Lamella slabs are used as the core in the manufacture
of sandwich panels.
Sandwich panels with a rock mineral fibre core have a wide range of applications particularly where acoustic or fire performance is important e.g. partition systems, external cladding systems, cold store panels and curtain walling spandrel panels.
Can be manufactured to tolerances of:
+/- 0.5mm on the thickness
+/- 2.0mm in the length and width.
Other finishes such as aluminium foil or tissue faces are available on request.
AIM Twin Scrim Lamella Pads are stretch wrapped onto wooden pallets with a showerproof polythene pallet cover and high quality edge protectors.
Bonded panels manufactured with lamella slabs offer
high resistance to transmitted sound.
Where perforated metal is used as a face, the panel with also provide good acoustic absorption.
Dimensionally stable and may be used with different materials on each side without fear of delamination due to unequal expansion.
Overall fire resistance is dependent on the type of facing used and the adhesive required to bond it to the lamella meaning any fire performance would need to be determined by testing.
Lamella slabs have excellent thermal performance.
Twin Scrim Lamella Pads are easy to handle but should be treated with relative care to ensure their integrity and shape is maintained.
Products are supplied on wooden pallets with edge
protection and a shower proof hood. Products should
be stored away from the elements until ready for
Should indoor storage be impossible the product should be stacked clear of the ground and covered with a stout tarpaulin.
This product does not contain moving parts and, if undisturbed in the cavity, requires no routine inspections or maintenance.
AIM Twin Scrim Lamella Pads are chemically inert, completely vermin and rot proof and do not encourage the growth of fungi, mould or bacteria. Lamella slabs are not known to degrade under normal conditions found in buildings and will perform effectively for the life of the building.
