sealed properly, improperly sealing around penetrations, etc. will impact the long-term performance of the insulation system. Designing, installing and maintaining the total insulation system properly cannot be over emphasized. Doing one without the other will have consequences. In the selection process of the primary insulation material, you often hear about hydrophobic, and water-resistant insulation. That can also be confusing. Hydrophilic material tends to repel or not to absorb water. Water resistant material is able to resist the penetration of water to some degree but not entirely unless it and the system is zero perm. These properties are important, but they do not replace the need for understanding the permeability of the material being considered for any application. Take the time to investigate and understand all physical properties of the insulation system components and their compatibility, inspect during the application what you expect and timely and properly maintain the insulation system. When in doubt, seek help, assuming could be costly. This article is provided by the National Insulation Association (NIA) as a RETA member service.
