| Step Edge Contrast - Design Philosophy |
|
The philosophy of the design is to make step edges visible using Ecoglo's high durability photoluminescent markers. Ecoglo photoluminescent markings have two components, a photoluminescent strip and an anti-slip strip. These two components create internal visual contrast thus ensuring the step edge contrast is independent of the tread surface (Fig 2.1). This internal contrast also ensures that visibility is good even under conditions of glare and visual reflectance. Step edge contrast should be on the tread of a stair, not the riser, because when either ascending or descending stairs the tread provides the visual information required to negotiate stairs safely (Fig 2.2). Ecoglo photoluminescent products are aluminium based and are manufactured using a patented heat curing process to ensure high durability to cope with the demands of high foot traffic. |
