HControl REFLEX+ is a reflective vapour control layer, which also acts as a supplementary insulating material due to its thermal resistance value, and high reflective properties. 


  • Complies with BS5250 - Code of Practice for Control of Condensation in Buildings
  • Can be used in conjunction with any type of insulation
  • Airtight
  • Watertight

A vapour control layer is a water vapour resistant material placed inside a heated space between the insulation and the internal lining.Its purpose is to block the transmission of water vapour. A vapour control layer also improves the airtightness of the building envelope.
