Stair Nosing LRV's
LRV's Light Reflective Values

The current guidance in the regulations BS8300:2009 is that adequate visual contrast is provided if the Light Reflectance Value (LRV) of the contrasting areas exceeds 30 points, “i.e., the contrast between the stair edging and the floor covering”. The testing equipment used to assess the LRV of C.A.T. product finishes is an integrated sphere spectrophotometer.

Stair Nosings FAQs

What is an Aluminium Stair Nosing or Stair Edging?

 

An aluminium nosing, sometimes described as an interior stair trim consists of a solid aluminium angle or aluminium capping shaped to increase slip resistance to the edge of a staircase. Some aluminium nosings are manufactured solid or with a recess for a secondary slip-resistant infill. These infills can be made out of metal or PVC and are manufactured in various colours to highlight the edge of the step, increasing safety. 

​

Are Aluminium Stair Nosings Anti Slip or Non-Slip?​

 

CAT stair nosing infills and treads have been independently tested for slip resistance values (SRV). For use in dry conditions all our stair nosings and infill test results show a low risk of slip. CAT also manufactures a range of purpose-designed stair nosings for use in external or wet areas which exhibit a low risk of slip in wet conditions. The values for each nosing style (click here) are for the normal direction of travel when installed on stairs, i.e., ascending and descending.

​

What is the best fixing option for Aluminium Stair Nosings?

​

It is recommended that stair nosings be installed using *adhesive and mechanical fixings to ensure against 'rattle' and achieve the most secure fixing. PVC Infill should be fitted at room temperature, not cold environments, to avoid the possibility of contraction.


CAT *recommend using STYCCO FLEX to fix any of its extensive range of stair nosings, stair edgings and stair insert products. STYCCO FLEX is a rapid curing flexible adhesive with excellent gap filling properties that can be used outside as well as inside. *subject to following the instructions given by F. Ball and Co Ltd in their STYCCO FLEX product technical data sheet, safety data sheet and installation guidelines, available in full from www.f-ball.com.

​

How do I Measure a Stair Nosing & Stair Edgings?​

 

When measuring stair nosings, steps should be numbered from top to bottom, indicating floor levels, flights and landings for the cutting and installation plan. Staircases with open strings should be measured oversize by 50mm for cutting on site. A measuring/ordering sheet can be found in our catalogue, or please call the CAT.

​

Are Stair Nosings a Legal Requirement?

​

In a commercial building, the use of stair nosings or stair edgings is a legal requirement. In the UK please refer to the Building Regulation Document K, Protecting from Falling and Document M, Access to and use of buildings.

​

Three Aspects to be aware of:

​

  • Size of Nosing - The recommended size of the tread should be 50-65 mm and the riser height should be 30-55 mm.

​

  • LRV's - The nosing is required to have a distinctive difference in colour from the floor covering. Measured as an LRV, Light Reflective Value, the difference between the floor covering and nosing must be a minimum of 30 points.

​

  • Slip Resistance - The material on the tread must provide a high level of slip resistance. Please note that all CAT Stair Nosings pass the Pendulum Test and all are designated with a low slip potential.
