Insulation calculator the insulation.
Thermafiber ultrabatt mineral wool is designed to provide excellent thermal insulation in residential and light commercial building.
The molten substance is spun into billions of fibers which are formed into insulating blankets with a high recycled content that provide fire resistive characteristics thermal insulation and sound control.
Noncombustible fire and moisture resistant they are designed to deliver thermal control and delay the spread of fire in wood stud cavities of exterior walls basements and heated crawlspaces.
The closer a climate gets to an extreme in heat or cold the more necessary it becomes to use insulation with a higher r value.
R value insulation chart now use the r value table to determine the recommended r value you need.
