Features: I-Joist Collapse applications of the coating are required, adding to the overall cost. Additionally, a major weakness in intumescent coatings is that in fire conditions, off-gassing within the coated lumber often leads to much of the protective material being ejected, rendering its protection useless. Major changes like this to the building code will add significant costs to residential construction, and so far no genuine market solution has been successfully brought forward. The Red Shield foundation is working hard to generate awareness and action to help the building code catch up to new advances in lumber protection technology, so homes can be built safer while remaining affordable.
