High vapour resistant insulator for air-conditioning applications

The main goal 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 flow of water vapor 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 vapor value corresponds to greater material resistance to water vapour penetration.

‘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 –55 ºC to +105 ºC. 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 and thermal performance. Thermal conductivity is the main data used to technical calculated insulation thickness required to prevent condensation.

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.

Other ‘INSU’ Range products:

‘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 and 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 per cent to 99 per cent infra-red radiation received by the surface of the heated slated roof.

‘INSUboard’ – Extruded polystyrene XPS is an ultimate solution for building insulation. It enhances the durability of the building structure and resists extreme ambient conditions, absorbs thermal shocks, mechanical loading and stresses without any deterioration in insulation properties of the product.
