Insulation in a New House

Submitted By

We are building a new house in Delaware and our builder wants to use a new type of insulation. The insulation is a combination of 1/2"close cell spray and a BIBS insulation. Our attic will have an R 45 and the walls will have a R 19 with the two types of insulation. The house will be constructed with 2x4 walls and a house wrap. Do you think we will have a mold problem because of built up condensation between the two types of insulation? Our builder said this would be a good way to get the R value we want for a good price. Thank you, Amber Carl
