Testing

Deck2Wall Spacers™ were tested at ICC-IAS accredited Washington State University. The testing was performed following the methods used which established the deck ledger connection provisions in Table R502.2.2.1 of the 2009 International Residential Code (IRC). The prescriptive IRC table is a valuable guide for ledger connections, but it is restricted to the test configurations that were used to develop to table. The IRC table does not prohibit other designs, as indicated in “R502.2.2.2 Alternate deck ledger connections. Deck ledger connections not conforming to table R502.2.2.1 shall be designed in accordance with accepted engineering practice....”

Our testing expanded on the IRC table. The five test configurations included our original 5/8” thick Deck2wall Spacer, 5/8” nominal sheathing, 1/2” and 5/8” diameter lag screws, 1/2” and 5/8” diameter bolts, and one configuration with our 1/2” thick SWS spacer, 5/8” sheathing and a structural wood screw that is specified in the table. The fastener spacing shown in our tables indicates the remarkable performance of the Deck2wall Spacers as outlined in the report.
