To save money on heating and cooling, getting your steel building properly insulated is key. Insulation is an important component of any steel building, and General Steel offers several insulation options. The various insulation options differ in price range and R-values, so you can find the most affordable option for your project. R-Value is a measure of the insulation’s ability to resist heat flow. The higher the number, the better it is at resisting heat flow. Below are R-Values for batt, foam board, insulated panels, and spray foam by thickness.
Since steel is a conductive material, you can lose heat through the walls if the building is not insulated properly. When your steel building is insulated correctly, you can avoid the possibility of rust and limit the noise of hail or rain makes on your metal roof. With that being said, we generally do not recommend using spray foam as it is more expensive and tends to trap moisture which then creates mold. The trapped moisture will, after time, start to corrode and rust away from the underside of the metal panels.
