Fibertex-B40 and R40 are an economical lightweight mineral fibre for thermal and acoustic insulation, specially designed for building application. They consist of long, fine fibres spun from molten natural rock bonded by thermosetting resin. Fibertex-B40 is supplied in flexible roll form for ease of installation over large areas such as roofing, siding. Fibertex-R40 is supplied as sheet for better rigid application.

• Fire Resistant
• Made from Stone
• Saves Energy
• Sound Absorbent

Fibertex-B40 is suitable for lining underside of metal sheet roof, inside of wall siding, in order to reduce heat gaining, absorb rain noise into the building.

Technical Parameters

Fibertex-B40 is easily installed on building envelopes. Firstly, preparing wire mesh to support blanket, then lining insulation inside, finally closing sheet to be finished. Fibertex-R40 often used as infill in cabity wall or partition to improve thermal resistance and sound attenuation.
