Many builders choose to hire an insulation contractor for their industrial or commercial building project. Hiring a qualified insulation contractor will be worth the investment, to insure that the work will be performed according to local codes, rules and regulations, and be guaranteed. A qualified insulation contractor will be able to recommend the correct R-value for your industrial or commercial insulation needs. The R-value refers to the barrier's resistance to heat. For example, single pane glass window is R1, double pane glass window is R2, triple pane glass window is R3, a stud wall made of 2x4s with 3.2 inches of fiberglass is R12, and straw bales provide heat resistance in the R40 to R50 range.
