ROCKWOOL FIBERTEX R120 
COMPRESSION BOARD 

Product Description
Fibertex-R120 is highly density thermal insulation with superior compressive strength, specially designed to bear heavy load. It consists of long, find fibres spun from molten natural rock bonded by thermosetting resin. 

Fibertex-R120 is supplied as rigid sheet which not easy to bend. Slitting or kerfing should need to conform curved surface for closely attachment.

Applications
Fibertex-R120 provides superior performance of thermal resistance, sound absorption and compression resistance in wide ranges of building and industrial applications. These advantages are particularly useful where the insulation may be subjected to mechanical loads or vibrations. Fibertex-R120 is suitable for resilient load-bearing characteristic required in vibration isolation of wall, floor and other structures.

Nominal Density 
120 kg/m 3 (7-1/2 lb/ft 3)

Maximum Service Temperature 
Recommended operating temperature up to 650 C (1202 F) 

Capability of handling intermittent temperature up to 1000 C (1832 F). At high temperature, R120 demonstrates higher compression resistance than lower density.

Fusion Temperature 
Fusion temperature or Melting point of rockwool at 1350 oC (2462 oF) 

Thermal Conductivity 
0.034 W/mK at 20 oC mean temperature (0.235 BTU in/ft 2h F at 68 F) 

Factory Applied Facings 
Product is available to order with ranges of factory applied facings such as various grades of aluminium foil, glass cloth, glass matt, polyester laminate. 

Fire Performance 
Bradford Rockwool 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) for non-combustible material.

Moisture Resistance 
Exposure to an atmosphere of 50 oC 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. 

Corrosion Resistance 
Fibertex-R120 is faintly alkaline and not accelerated with steel, copper or aluminum. When tested in accordance with BS 3958: Part 5 : 1969, results in range of pH 7.5 to 8.0. Fibertex-R120 contain less than 15ppm soluble chlorides.

Compression Resistance 
Fibertex-R120 is a resilient material which readily returns to original shape after removal load. The result between reduction in thickness (%) versus compressive load (kPa) following BS-2972 ; 1975 :
