Technical Documents
The SPFA Technical Committees have developed a library of documents for SPF contractors as well as architects, specifiers, builders, and code officials.
There are two types of SPFA documents:
- SPFA TechDocs are detailed documents that describe specific applications of SPF and are useful to both SPF contractors and design professionals.
- SPFA TechTips are short articles for installers.
The documents are FREE to SPFA Members and can be accessed through the Member InfoHub. Non-members may purchase the TechDocs from the SPFA Store.
