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.
