ROCKWOOL FIBERTEX 350 / FIBERTEX R60
INDUSTRIAL BLANKET AND BOARD |
 |
Product Description
Fibertex 350 is an economical lightweight mineral fibre for thermal and acoustical insulation. It consists of long, fine fibres, spun from molten natural rock and bonded with thermosetting resin.
A suitable finish such as metal cladding is recommended to protect the insulation from weather or mechanical damage.
Fibertex 350 is supplied in flexible roll form and semi-rigid slab for a wide variety of applications, at both high and low temperatures. |

Applications
Fibertex 350 is particularly suitable for thermal insulation, for Process temperature control, HVAC-ductwork, Hot and Cold piping, Refridgeration equipment, Wall lining, Storage tanks, Heat exchangers, Stacks, Vessels and Ovens.
Fibertex 350 is easily installed by impaling pins and securing with speed clips. For small vessels, we can retain insulation by wire mesh or metal bands. In case of irregular shaped or small diameter vessels, Fibermesh-450 is recommended. Furthermore, it can be used as acoustic insulation for noise control as lining on walls or as an absorbent medium in silencers. With high melting point fibres, it can be used as fire safing insulation in Fire door and Fire walls.

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 350 achieves four zero Early Fire Hazard Indices when tested in accordance with AS 1530:Part 3-1976 (same as BS 476 : Part 5, 6, 7-1967) for non-combustible material. Moisture Resistance
Exposure to an atmosphere of 50 C and 95% relative humidity for 96 hours results in moisture absorption of less than 0.2% by volume. Should insulation become wet, full thermal efficiency will be restored on drying out.
Water repellent grade according to BS 2792 section 12 is available to order.
Corrosion Resistance
Fibertex 350 is faintly alkaline and is incapable of corroding steel, copper, or aluminium. To maintain this condition, protection must be provided against contamination from external sources. When tested in accordance with BS 3958: Part 5-1969, results in range of pH 7.5-8.0, Fibertex 350 contains less than 15ppm soluble chlorides. For critical applications involving austenitic stainless steel, a low chloride formulation is available to order.
