Temperature and Climate Details for Blueboard Temperature and Climate Details for Blueboard

Blueboard is a foam product that is used both on the interior and exterior of homes for added insulation as well as a layer of protection against moisture. Typically it is applied to the exterior of a home, underneath siding or other finishes, but can also be used on the interior of a home, such as in basements where there is usually an increased level of moisture that seeps through concrete as well as cooler temperatures. Blueboard works to mitigate extreme temperature fluctuations, and is ideal to use in cool, damp climates. It has a melting point of 165 degrees however, so it may not be the material of choice in the southwest desert climates. Blueboard is typically installed using construction adhesive, as holes put in the blueboard will result in compromising it's temperature moderating qualities and will result in a lower R-value for the material.

From the Northern Midwest to the East coast, blueboard is an ideal option whenever there needs to be better insulation to walls or basements. Blueboard carries an R-value of 4.5 to 5 per inch of material, and can make a significant difference in the efficiency of a home. In climates with temperature extremes, being able to reduce radical shifts in temperature to the home will make it much easier and less expensive to heat and cool. While it may not be feasible to remove existing siding or existing finishes to add it, it will likely be ideal to be used in any type of new construction or addition to an existing home. Too, if one is finishing a basement, insulation in general is a major consideration, and blueboard can be the ideal solution for both it's insulating qualities as well as it's moisture repealing qualities. While to does not eliminate moisture from seeping in, it does provide a better barrier than none at all.

Interior Use

Because it is porous, it should be covered with vinyl sheeting or heavy plastic to provide additional protection from unnecessary exposure to moisture when used in interior applications. It will also need to be covered when being used indoors in living areas such as bedrooms or recreation rooms as due to the low melting point it will catch quickly in the event of a fire, and will add fuel to the fire. When blueboard burns, toxic fumes result that will poison people or animals in the vicinity. Due to this, blueboard should only be added to areas that will be finished with sheetrock or some other type of gypsum drywall product to serve as an extra layer of fire protection to the home.

Other Uses

Blueboard can be used on a variety of exterior buildings as well to help insulate them and protect them from moisture. Blueboard is also used to insulate bee hives, build scale air planes, and various other applications. Whenever a light moisture proof material is needed, blueboard is a good option for many.
