Check the Label Before You Buy

No matter what kind of insulation you buy, check the information on the product label to make sure that the product is suitable for the intended application. A good insulation label should have a clearly stated R-value, and information about health and safety issues. An informative label should state:

• The type of insulation material;
• The R-value (measured at 75F);
• The types of spaces that can be insulated;
• Safety precautions in application and use, including any fire-hazard related restrictions;
• The quantity in the package;
• The name and address of the manufacturer or distributor.
