Supreme introduces INSUflex, which has a high diffusion resistance factor to water vapour transmission ≥7000, a low thermal conductivity and excellent fire safe performance. It is suitable for a temperature range from –55ºC to +105ºC. The product does not depend on any additional outer thick skin or coverage. But, is built in with the insulation and extends through the full thickness. It provides a very high efficient method of insulating to control 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 sheets / rolls in air-conditioning ductwork.
INSUflex products are resistant to corrosion fungal and mildew growth. Thus they are suitable for clean room applications. Insulation material with low ‘K’ value exhibits high energy saving potential & thermal performance. Thermal conductivity is the main data used to technical calculated insulation thickness required to prevent condensation.
The main aim of a good insulation material should be that of preventing water vapour from spreading through insulation as water is an optimal heat conductor. INSUflex, having a high water vapour resistance factor, can prevent a flow  of water vapour that tends to pass through the insulating material created in air-conditioning system as result of difference in pressure between the pipe (low pressure) and the surrounding air temperature (high pressure). A high water vapour value corresponds to greater material resistance to water vapour penetration.
Ever since a catastrophic fire in an insulation manufacturing facility, foreign manufactured materials have been more amiable to all. The end-user, in many cases, does not place primary importance on where the product is made if the product meets the specification. Therein lies a very important question, does the foreign manufactured material meet the applicable material specification and standards? It may look and feel the same and is in a similar wrapper but is the composition, health and safety aspects, quality and its performance standards measured on the same basis as domestic manufactured materials?

This is not suggesting that imported materials are inferior to those manufactured locally. It is simply raising a caution flag to those individuals and companies that are considering the use of imported materials. Are they tested and is the performance being measured on the same basis considering local ambient conditions? The burden of proof and ownership of the material ultimately lies with the end user but all channel participants involved in the decision making process will shoulder some degree of responsibility if a failure were to occur. A failure of any magnitude and regardless of the cause is detrimental to the industry. Assumption of equivalence and warranty support could be costly. Unless financial instruments / funds are involved guarantees / warranties do not leave the user much choice.
Advantage INSUflex•  Good flexibility at low temperature•  Clean, dust-free, fast and easy installation• Low thermal conductivity•  High water vapor resistance factor ≥7000• Protects pipes against corrosion by environment elements•  Low toxicity index means minimal toxic fire hazard for safety assurance and rescue operations•  Good fire performance, for buildings with high occupancy, Class 1 product•  Unique closed cell structures, provides an ideal vapor barrier resistance.
INSUflex is available in combination of various wall thicknesses and diameters to suit G.I., copper and PVC pipes. The product 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.
