Reducing The Effects Of UHI

An Urban Heat Island is a built-up or metropolitan area in which observed temperatures are significantly higher than surrounding rural areas, primarily as a result of heat retaining materials used in construction. Although this is an issue that may not seem particularly applicable to the UK climate, it is still a consideration in certain environments and for certain structures and makes an interesting case study.


The Hyperdesmo System including Hyperdesmo and ADY-E is a CE certified waterproofing and protective system for exposed used but is also a certified cool material, reflecting up to 82% of the Sun’s radiation:

  • Solar Reflectance (SR):  0.82
  • SR Index (SRI):  102
  • Infrared Emittance (IR):  0.87

These values endure with time since the colours do not fade and the coating is fully washable.


What are the benefits of these reflective qualities?

  • Reduces temperatures inside building during warm months
  • Lowers energy requirements for keeping building interiors cool
  • Increased protection leading to greater longevity of structural elements
  • Contribution towards reduction of UHI effect


The Hyperdesmo System is THE polyurethane liquid membrane for exposed use.  It can be used for the waterproofing and protection of:

  • Cement
  • Insulation Foams
  • Asphalt
  • EPDM Membranes
  • Bathrooms
  • Balconies
  • Roofs
  • Light metal or fibrous cement roofing
  • Stadium Stands
  • Car Parks
  • Bridge Platforms
  • Irrigation Channels
