FIBRANgeo BP-50-L rigid stonewool insulation board is a natural inorganic fibrous product that is industrially produced from molten rock spun into fibres, in accordance with European Standard EN 13162 (Thermal insulation products for buildings-Factory made mineral wool (MW) products). All four edges of the boards have L-cuts (shiplap) profiles. The cut is positioned in the middle of the edges and it is 15mm deep.

Applications
Boards designed for thermal insulation, fire resistance and sound insulation applications where increased mechanical properties and resistance to compressive stress is required.

On flat roofs, such as:

• External thermal and sound insulation of flat roofs, with stonewool that is covered by screed and water-insulation layer.
• External thermal and sound insulation of concrete or metal flat roofs, with stonewool that is covered by waterrinsulation membrane layer.

FIBRANgeo products must be protected from getting wet before and on their application. If part of the product gets wet, it must be dried before installation. Stonewool dries quickly and its insulating properties remain uncharged after drying. Packaging should be removed carefully just before the installation. 
Working areas should be kept clean. Unnecessary or extensive contact of the skin and eyes with product’s off-cuts, fibres and dust should be avoided, and protective wear should be used (gloves, goggles, hats).
Products with facing AL, AX, YM and YA are not suggested for application with service temperature on the surface more than 90 oC while those with surface XA are not suggested for more than 66 oC.
Sufficient ventilation of the working areas should be ensured, whilst power sutting tools should always be equipped or supplemented with a mechanical system of dust intake.
