Is Kingspan Insulation affected by Water or Moisture?

Both of the Kingspan Kooltherm and Therma ranges of insulation are closed cell types of insulation. This type of insulation is resilient to the occasional light sprinkle of water but should always be kept and stored in dry conditions to maximize their thermal performance.

Where the Kingspan insulation is expected to get wet or where it is to be installed outside any tanking membrane, we would recommend using the Kingspan GreenGuard which isn’t negatively affected by ground water or moisture.
