POLYWOOL Sectional Pipe Insulation (SPI) offers a range of sectional pipe insulation suitable for the external insulation of pipework. Manufactured from rigid glass mineral wool pre-moulded into one-piece cylindrical sections. It provides excellent thermal insulation up to a working temperature of 350oC as well as personnel protection and energy saving benefits.
POLYWOOL range of sectional pipe is available either in plain or faced with Sisalation foil. POLYWOOL SPI is available in 1 metre lengths, faced or unfaced, and with a variety of wall thicknesses to suit standard steel pipes and copper tube from 12.7mm to 355mm O.D.
SUSTAINABLE PRODUCT
POLYWOOL SPI is free from CFCs, HCFCs and any other material with ozone depletion potential in their manufacture/composition content, and represent no known threat to the environment. Made from nearly 80% recycled glass and locally sourced raw materials, POLYWOOL SPI range of glass mineral wool is perfectly in tune with sustainability and environmental concerns. POLYWOOL SPI is compliant with most green rating tools ODP Emissions credit requirements. Air quality is maintained with total Volatile Organic Compound (VOC) emissions below quantifiable levels.
APPLICATION
It is designed to be used on commercial, process lines where fire safety and a pleasing appearance are desired. Hot Applications POLYWOOL SPI does not require a facing for hot work. However, a metal cladding (generally swaged galvanised or aluminium metal sheathing) is recommended on all outdoor applications, or on indoor applications where protection from physical damage is required.

THERMAL PROPERTIES
POLYWOOL SPI allows to optimise energy efficiency, prevent heat loss and provide effective thermal insulation. Properly insulated pipes will be able to limit the heat loss and maintain the desired operating temperature. Complies with ASTM C518 at 15°C mean temperature. Thermal conductivity value as low as K0.300 W/mK
