Calculating Rows Needed:
Run (distance from eve to ridge) x Snow Load x CTC of Panel in feet.If you have a 20' run x 30# Snow Load x Using 12" CTC Panels.20 x 30 x 1 = 600#PSFThe adhesive mounted system is rated for in excess of 800#PSF when correctly installed with SB-190.These guards are rated for in excess of 3000#PSF when correctly installed with mechanical fasteners (Min. 4).For Adhesive Mounting:As long as your number is below 800# PSF, one row should do the job. If your number is 800-1500 you will need to add a second row to distribute the weight evenly. The first row over the weight bearing wall, the second row half-way between the first row and the eve.1600-2300 will need 3 rows and so on.For Mechanical Fastener Mounting:Up to 2900 - 1 Row3000-5900 - 2 Rows6000+ - 3 Rows or More.Suggestion: For panels over 12" in width, you can use multiple guards per panel to assist in lowering the effective snow load on each guard. We would recommend using 2 on panels over 16" to prohibit snow from coming around the guards. Likewise for panels over 30" we would recommend 3 per panel.Not sure on the exact quantity you need? Feel Free to reach out to us via phone or email and we will help you configure a custom layout for your application. There are many factors that must be taken into account to assure your snow retention system performs properly. The above information is a guideline and the ultimate responsibility for the success of the system is with the installer.
