High-performance buildings can significantly reduce global CO2 emissions and mitigate climate change. Building codes should mandate the healthiest, most energy-efficient and structurally sound systems for home and building construction. Continuous Wall Insulation (CWI) is a cost-effective solution that provides water, air and moisture resistance as well as structural integrity.

Key Facts

  • CWI can significantly reduce the energy demand of home heating and cooling systems. Polyiso CWI creates an uninterrupted barrier that reduces thermal bridges by providing a continuous layer of insulation over the entire wall surface, which increases the energy efficiency of a home.
  • Not only does polyiso deliver a high R-value per inch compared to other types of continuous insulation, but it also adds structural stability, creating a more durable wall. Laminating polyiso to structural materials increases the dimensional integrity of the wall.
  • Adding CWI to cavity insulation protects interiors and wall cavities from condensation and keeps moisture from entering the house, reducing the risk of rot and rust. CWI is also a secondary line of defense against rainwater intrusion.
