INSUflex, by Supreme Industries, is a CFC-free, black flexible elastomeric closed-cell Nitrile Rubber thermal insulation that provides a highly efficient method of insulation and effectively controls condensation against both heat loss and heat gain. The material is particularly suitable for insulating pipe works for condensation control. It can be used on chilled water pipe lines, refrigerated pipe-works, hot & cold water services and on sheets or rolls in air-conditioning ductworks. The product is available in combinations of various wall thicknesses and diameters to suit G.I., copper and PVC pipes. It is applied to the surface using an adhesive compound. A protective layer of glass cloth, in two layers with an adhesive compound is then applied before providing a weather barrier, such as aluminium / G.I. cladding for outdoor application.

INSUflex range is resistant to corrosion, fungal and mildew growth and is therefore suitable for clean room applications. Insulation material with a low ‘K’ value equates to a high energy saving potential and thermal performance. Thermal conductivity is the main data used to technically calculate insulation thickness required to prevent condensation. It has a very high diffusion resistance factor to water vapour transmission ≥7000, a low thermal conductivity and an excellent fire safe performance. It is suitable for a temperature ranging from –55oC to +105oC. The product does not depend on any additional outer thick skin or covering but is in built with the insulation and extends through the full thickness.

Other ‘INSU’ Range products are INSUshield and INSUreflector. INSUshield is a non-fibrous, fire retardant (‘Class O’ in Fire Propagation and ‘Class 1’ in Surface Spread of Flame), closed cell, tri dimensional chemically crosslinked polyethylene XLPE foam. An ideal environment friendly insulation material, with a perfect solution for all your insulation needs for ducts, roofs, pipes, vessels, etc. The divergent advantages of ‘INSUshield’ are ease of installation, low thermal conductivity and good moisture & vapour resistance preventing microbial growth and optimum condensation protection. INSUreflector is a radiant heat reflective insulation material made of polyethylene air bubble film (ABF) laminated with aluminum foil on one or both sides. It is a low e-reflective insulation material with a low mass to air ratio, which effectively blocks the radiant heat transfer. The bright surface of the aluminium foil, which encases the FR polyethylene air bubble material, reflects 96% to 99% infra-red radiation received by the surface of the heated slated roof.
