Insulation choice can be confusing, but our insulation contractors use a measured value called the "R-Value" to help explain how effective each form of insulation will be for your project. Flower Mound Insulation contractors will give you a rough estimate after measuring the length and height of each wall in the room or area our customers are wanting to insulate. The length and height will then be multiplied to find the total square feet. estimate after-V The R value is given to determine how effective each type of insulation will be for your insulation project. The higher the R value, the better the insulation power. We always recommend that walls, ceilings, attics, and spaces between your interior and exterior walls be insulated. Our Flower Mound Insulation contractors recommend an R value of 12–24 for exterior walls or a value of 30–40 for attics and ceilings. Call us today to discuss your project.
