Fibertex Rockwool SPI

Bradford Fibertex™  Sectional Pipe Insulation (SPI) is preformed moulded rockwool sectional pipe insulation to limit energy loss and provide personnel protection from industrial piping suitable for continuous operation up to 650°C.


Bradford Fibertex SPI is a formed rockwool insulation product. It is manufactured by spinning a molten mixture of natural rock and recycled products into fine wool like fibres. The SPI is then rolled into shape and the fibres are bonded together using a thermosetting resin to form the final product. This process ensures the fibre orientation is perpendicular to the heat flow ensuring maximum thermal performance.

Rockwool SPI is available in 1200mm long pipe sections of varying diameters and thicknesses. SPI sections are slit to facilitate easy installation over insitu piping. SPI diameters are manufactured to fit over standard piping sections. The product can be identified by its dark green/brown appearance.
