This website discusses how to inspect, diagnose problems in, and install or repair building insulation & ventilation systems including heat loss, moisture, & interior stains. Because no amount of insulation can keep a drafty building warm, also review Priorities for building energy efficiency. Also see HEAT LOSS INDICATORS (where is the building losing heat during the heating season, or gaining un-wanted heat during the cooling season), and see HEAT LOSS R U & K VALUE CALCULATION for a guide to calculating heat loss (or gain) rates for buildings and building insulation.

Guide to Inspection of Building Insulation: insulation material identification, insulation R-values, insulation characteristics

The websites and articles listed here provide in-depth discussions of how to identify various types of insulation, where insulation defects occur and what is their effect on buildings, and we discuss various indoor air quality issues involving building insulation such as asbestos and fiberglass particle contamination, mold in insulation, and building moisture and condensation where insulation and ventilation have not been properly installed.

Insulation products are used in a very wide range of building products and building locations besides attic, ceiling, and wall insulation. Some kinds of insulation can be tricky to identify and may have special concerns which are discussed in these articles.

Links at page left organize our articles on building insulation inspection, hazards, and insulation properties. Additional insulation articles are listed just below.
