A partial fill cavity wall application provides the most effective barrier to rain penetration by allowing the traditional wall cavity to be maintained. The insulation is fixed to the inner leaf of the wall construction, maintaining a clear cavity that avoids the problems associated with full cavity fill.

For this application use either Kingspan Thermawall TW50 zero ODP (high performance CFC/HCFC-free rigid urethane insulation) or Kingspan Kooltherm K8 zero ODP Cavity Board (premium performance CFC/HCFC-free rigid phenolic insulation).

• Utilises traditional cavity wall construction methods
• Clear cavity is maintained -resists moisture penetration
• Meets NHBC technical requirements when used with a 50mm residual cavity
• Unaffected by air movement
• Easy to handle and install
• CFC/HCFC-free with zero Ozone Depletion Potential (ODP)
