ROCKWOOL FIBERTEX B40 / FIBERTEX R40
INDUSTRIAL BLANKET AND BOARD |
 |
Product Description
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.

Applications
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.
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.

Factory Applied Facings
Product is available to order with wide ranges of factory applied facings such as various grades of aluminium foil, glass cloth, glass matt, polyester laminate.
Fire Performance
Fibertex-B40, R40 achieve four zero of Early Fire Hazard Indices when tested with AS 1530 : Part 3-1976 (same as BS 476 : Parts 5, 6, and 7;1967).
They do not ignite, spread flame, evolve heat, or develop smoke, so they are non-combustible material.
Corrosion Resistance
Fibertex-B40, R40 are faintly alkaline and not accelerated with steel, copper or aluminum. To maintain this condition, protection must be provided against contamination from external surrounding. When tested in accordance with BS 3958:Part 5: 1969, results in range of pH 7.5 to 8.0. They contain less than 15ppm soluble chlorides.
