Technical Note No. 018 L'P <br /> .............. <br /> BUILDING PRODUCTS <br /> Installing LP° SmartSide® Trim and Lap Siding on Rigid Foam Insulation <br /> over Furring Strips (VLlit Wind Speeds) <br /> This Technical Note is an addendum to the LP® SmartSide® Trim and Fascia, and LP® SmartSide® <br /> Lap Siding Application Instructions ("Instructions"). It is intended to provide an alternative <br /> fastening option for LP SmartSide trim and lap siding on rigid foam insulation over furring strips. <br /> The Instructions remain effective except as may be modified by this Note. Refer to the <br /> Application Instructions for all other aspects of product installation. <br /> Trim and lap siding may be installed on rigid foam insulation over furring strips: <br /> • Trim and lap siding must be installed over a minimum 1x4 nominal size Southern Pine <br /> furring strip with a specific gravity greater than or equal to 0.55. <br /> o Install furring strips no more than 16"o.c. in wind speed areas less than or equal <br /> to 200 MPH1 <br /> • Siding shall be installed to safely resist all loads, including wind loads, of the locally <br /> adopted building codes. The installation of siding shall result in a system that provides a <br /> load path that meets the requirements for the transfer of loads from their point of origin <br /> through the load-resisting elements to the structure. The mechanical connection of the <br /> furring strip to structure is the responsibility of a design professional. LP assumes no <br /> liability for any loss or damage caused by the design of the mechanical connection of the <br /> furring strip to the structure and is expressly released by the purchaser or owner from <br /> any such loss or liability. <br /> • Minimum Fastener Type: <br /> o Corrosion Resistant— Hot Dipped Galvanized or equal (ASTM A153)2 <br /> o Ring Shank3 <br /> o Shank diameter = 0.120 inch <br /> o Head diameter = 0.270 inch <br /> o Length = fastener shall fully penetrate a minimum 1/2 inch into nailable furring <br /> • LP always requires the use of a WRB behind LP® SmartSide® products. LP has no <br /> responsibility for any damage arising from a failure to use a WRB. <br /> Page 1 of 3 <br /> ADDRESS 414 Union Street <br /> Suite 2000 <br /> Nashville,TN <br /> TEL (615)986-5600 <br /> FAX.
