INSULATED SHEATHINGS
•  LP

 SmartSide
® 
 Panel siding may be 
installed over low-compression rigid 
foam or exterior gypsum. 
These precautions must be followed:
•  Adequate bracing of the wall in 
accordance with International Codes or 
other ruling building code is required.
•  For rigid foam sheathing up to 1 inch 
(25.4 mm) thick, siding may be nailed 
directly to the foam sheathing unless 
a drainage plane is required by the 
local building code. Nail length must be 
increased to ensure a minimum 1-1/2" 
(38.1 mm) fastener penetration into the 
structural framing.
•  For rigid foam sheathing greater than 1" 
(25.4 mm), a minimum 1-1/2" (38.1 mm) 
thick by 3-1/2" 
(88.9 mm) wide vertical 
strapping or furring strip must be 
installed over the sheathing to provide 
a solid, level nailing base for the siding. 
The strapping must be securely fastened 
to structural framing, spaced no greater 
than 16" on center 
(406 mm), with a 
minimum nail penetration of 1-1/2" on 
center 
(38.1 mm) and a maximum nail 
spacing no greater than the width of the 
siding. 
•  LP
® 
 will assume no responsibility for any 
damage or condition arising from the 
use of rigid foam or exterior gypsum.
