This method of insulating is also suitable for existing buildings where the tiles/slates need replacing. For this application use either Kingspan Thermapitch TP10 zero ODP (high performance CFC/HCFC-free rigid urethane insulation) or Kingspan Kooltherm K7 zero ODP Pitched Roof Board (premium performance CFC/HCFC-free rigid phenolic insulation) between rafters with Kingspan Thermawall TW56 zero ODP beneath the rafters.

• On average its use creates 15% more usable warm roof space
• Insulation of pipes and tanks is unnecessary
• No condensation risk
• Unaffected by air movement
• Resistant to the passage of water vapour
• Easy to handle and install
• Ideal for new-build and refurbishment
• CFC/HCFC-free with zero Ozone Depletion Potential (ODP)
