Tile Roofs: Install ridge and soffit vents as specified by manufacturer and in accordance with drawings. ** NOTE TO SPECIFIER ** Delete the following paragraph if Weathershield flashing is not required by imbalanced venting conditions. J. Flashings: Install specified flashings where indicated on the drawings. 3.3 SOFFIT VENTS A. Install continuous vents full length of soffits, unless otherwise indicated. B. Ensure that adequate blocking or barriers are installed to prevent insulation from impeding air flow. 3.4 SIDING VENTS A. Nail SV-3 or SV-5 in a continuous band along the wall at the level where the siding will start. A continuous band of SV-3 or SV-5 may also be nailed at the top of the wall where the siding ends if full ventilation behind the siding is desired. SV-3 and SV-5 may also be used above and below windows and above doors to provide drainage/ventilation in these areas as well. B. If SS-112 Sturdi Strips are being used with the SV-3 they should be nailed to the wall either at 16 inches (406 mm) OC or 24 inches (610 mm) OC, depending on the stud layout of the wall and alongside all windows and doors. Note the SS-112 are a spacer and are not designed to hold the weight of the siding, the siding must be fastened through the SS-112 Sturdi Strips into structural material behind them. Typically when the SV-5 is being used a 3/4 inch (19 mm) thick furring strip is used instead of the SS-112 Sturdi Strips, but they can be doubled up and used if desired. The fastener for the siding must be long enough to go through both layers and attach to structural material behind them. C. The ST-30 Sturdi Starter is used instead of ripping a piece of siding to place behind the bottom of the first row. The ST-30 will provide the same angle as the ripped siding to the first row of siding. 3.5 ADJUST AND CLEAN A. Remove any scrap from the site, and leave in a neat and clean condition. END OF SECTION
