‘Polybond’ Lamella Mat

‘Polybond’ Lamella Mat is formed from strips of Mineral wool bonded on edge to a flexible outer facing. Lamella Mat is particularly suitable for the insulation of heating and ventilation pipe work and duck work and as an overly to upgrade existing insulation. Utmost care should be taken to ensure that the fibers are oriented perpendicular to the width of the two metal surfaces, in order to achieve optimum compression strength.


‘Polybond’ Lamella is used for thermal and acoustic insulation where high compressive strength is required. It is commonly used in heavy loaded sandwich panel, floor and roofs.
