How to Increase R-Value

InSoFast Plus Method

Need a higher R-value? It’s easy to increase your R-Value beyond R-10 while maintaining the engineered benefits of the continuous InSoFast panels. Simply layer rigid foam insulation board over top of InSoFast panels, InSoFast PLUS. This saves money by utilizing locally obtained rigid foam to enhance the R-Value. Additionally, projects can be completed in a fraction of the amount of time because they start with a base of feature-rich, low-labor InSoFast panels.

In cavity insulation systems, traditional stud framing can account for at least 25% of wall space. When the studs are uninsulated, there is enough thermal bridging to drop the R-Value from 19 to 12.5 – nearly a 35% loss, which can render any additional layers of insulation useless.

Building codes have higher requirements for cavity insulation to make up for the uninsulated studs or framing members. That is why basement wall code reads 10/13 in many climate zones. It can be R-10 continuous insulated sheathing on the interior or exterior of the home or R-13 cavity insulation along the interior of the basement wall.
