There are several types of insulation on the market today and there will be new ones in the future. There is no required colour code for insulation, but often manufactures will use one colour for their products. The various characteristics of each type, need to be taken into consideration when deciding what insulation to use. Being knowledgeable about what product to use will help to ensure the overall effectiveness of the job, the longevity of the insulation, the efficiency of the home, and the comfort of the occupants. This in conjunction with proper air and vapour retarder installation will lead to a more cost effective, comfortable, and durable home that helps to avoid moisture problems. It also helps to avoid Indoor Air Quality (IAQ) issues related to moisture.
