U- type and in accordance with standards EN13374 and EN1263, their mesh size must not exceed 100 x 100 mm. Users must ensure that there are enough attachments on the net or wire netting according to their capacity. You can also install solid sidewalls with wooden or metal boarding. If they are exposed to high winds, they will require a special technical study. Determining the height of the guardrail: h min The height of the guardrail for roofer protection should be determined according to the construction detail of AFNOR's NF 096 certification framework. Formula: h min = 1.50 m + h1 - d where hmin = minimum height of the protection system with h ≥ 1.00 m h1 = outclass between the gutter and the deck with h1 ≤ 0.80 m d = distance between the inside of the protection system and the gutter with d ≥ 0.70 m Example of a 2.00 m safety guard h1 = 0.60 m d = 0.90 m h min = 1.50 + 0.60 - 0.90 = 1.20 m making a guardrail of 1.50 m to comply with the spacing of the scaffolding fixing nodes 01.11.17 T e c h n i c a l i n f o r m a t i o n
