Residential Insulation Best Practices – Part 3: Inspecting Installation Quality



Installing to Grade I criteria is important to delivering a quality, energy-efficient home. A Grade I designation means that the home insulation is properly installed and without any moderate or substantial defects. While Grade I installation should be the norm in the residential building industry, there are instances where it is not. The result of a sub-par installation is a home that doesn’t perform to its potential—which unfortunately reflects poorly on builders, installers and insulation manufacturers alike.

Our three-part batt installation training video is a great beginner’s tutorial or refresher on how to get Grade I installation and should be required viewing for all insulation contractors working with batt insulation:

Part three answers the question: “How do I install insulation?” Homes insulated with fiber glass, rock wool and slag wool batt insulation can meet RESNET Grade 1 insulation criteria when installed with professionalism and care. Walk with Brian Coble, Director of High Performance Homes for Advanced Energy, as he performs a detailed insulation inspection in an ENERGY STAR home. Issues such as batt insulation compression, vapor retarder facings, insulating around light fixtures, pipes, electrical wires, outlets, intricate framing areas, cantilevers, bay windows, corner cavities, band joists, knee walls, attic platforms, soffit dams and baffles, showers and tubs, and much more are covered.
