Indoor Pool Building
BSC investigated a 5 year old wood-frame indoor pool building in Climate Zone 6A. This work was prompted by reports of staining of the exterior siding; disassembly of the walls revealed substantial rot of the sheathing and the wood framing. BSC was asked to determine the cause of the damage, and provide recommendations for build-back in a moisture-safe manner. Exterior infrared inspection revealed warmer areas surrounding the window, especially at the sill/corner area. The wall was disassembled, revealing substantial decay of the OSB wall sheathing and framing (outboard side).
