The NSL28 Profile features an aluminum channel along with a selection of insert materials for both the tread and riser, allowing for the creation of a distinctive, contrasting solid band of color. This design is tailored to comply with the guidance outlined in Approved Document M and BS8300:2009+A1:2010, making it ideal for applications where no surface floor coverings are utilized or where resilient flooring is present.
When selecting the insert color(s), it's important to consider the respective Light Reflective Value (LRV) of both the surrounding floor covering and the stair nosing itself. The difference between these values should be greater than a factor of 30 to ensure sufficient contrast and visibility.
By adhering to these specifications, the NSL28 Profile offers a solution that not only meets regulatory requirements but also enhances safety and visibility in stairway environments.
