DmarcIKO D-marc™ 105 is a new wind-resistant demarcation system for flat rooftops. Applications may be for the purpose of preventing access to hazards during regular rooftop maintenance or to provide safe access across the roof.

Wherever roof access is required, designers are tasked with creating a safe route which should be identified by a demarcation system.

Traditional demarcation systems on rooftop applications suffer from instability and wind uplift causing them to fly off roofs at wind speeds as low as 50 mph.

D-marc™ 105 has been wind tunnel tested on single ply, bituminous and concrete roof surfaces,resisting wind speeds in excess of 105 mph.
