5 Types of Nosing to Upgrade Your Stairs in 2023

What is Stair Nosing?

Stair nosing, a crucial component in architectural design and safety, refers to the specialized strip attached to the front edge of each step in a staircase. This essential feature, crafted from diverse materials like metal, wood, rubber, aluminum, and vinyl, plays a pivotal role in enhancing the durability and safety of stairs.

What is the purpose of a nosing?

The primary function of stair nosing is to enhance the safety and accessibility of a staircase. By extending slightly beyond the edge of each tread, nosing creates additional surface area, offering ample space for the full foot to step securely. This extra space is particularly beneficial for taller individuals, providing more comfort as they ascend or descend the stairs.

Moreover, beyond its functional benefits, stair nosing contributes to the aesthetic appeal of staircases, offering a polished and finished look. Its versatility in material and design makes it suitable for various types of staircases, reinforcing the steps against wear and tear while providing additional grip to prevent slips and falls.

What is the standard nosing for stairs?

In discussing the standard nosing for stairs, it's essential to adhere to the specifications outlined by the International Building Code (IBC).

According to IBC Section 1011.5.5, "Nosings shall have a curvature or bevel of not less than 1/16 inch (1.6 mm) but not more than 9/16 inch (14.3 mm) from the foremost projection of the tread."

Furthermore, the risers must be "solid and vertical or sloped under the tread above from the underside of the nosing above at an angle not more than 30 degrees (0.52 rad) from the vertical."

The IBC also mandates in Section 1011.5.5.1 that the leading edge of treads should "project not more than 1 and 1/4 inches (32 mm) beyond the tread below" and insists on the uniformity of these projections as per Section 10115.52.

Moreover, while risers are generally required to be solid, exceptions are detailed in Section 1011.5.53, noting circumstances under which solid risers are not obligatory, such as in certain occupancy classifications and stairway types.

By incorporating these standards, we can ensure that stair design prioritizes safety and compliance with established building codes.

Thickness of the Nosing

Taking into consideration that staircases may be covered with carpeting, it's important to ensure that the stair nosing aligns as much as possible with the floor covering to avoid tripping hazards.

The maximum allowed nosing, as per the requirements outlined by the International Residential Code (IRC), is 1.25 inches.

However, it's crucial to pay attention to the Light Reflectance Value (LRV) of the color of the anti-slip strips when choosing nosings with this feature.

FAQ about Stair Nosing Types

How to attach stair nosing?

You should involve the following steps when attaching stair nosing :

  1. Preparation: Clean and level the stairs. If the steps are smooth, roughen them up for better adhesion.
  2. Measure and Cut: Measure the stair width and cut the nosing strip to fit.
  3. Test the Fit: Place the strip on the stair tread to test the fit.
  4. Apply Adhesive: Apply adhesive to the stair nosing and treads, starting from the top step.
  5. Attach the Nosing: Place the nosing into the adhesive, ensuring it is flush with the riser.
  6. Secure the Nosing: Secure the nosing with nails or screws if necessary.
  7. Clean Up: Remove any excess adhesive before it dries.

  3. Attach the Nosing: Carefully position the nosing and press down firmly along the entire stair nose.
  4. Let Adhesive Cure: Allow the adhesive to cure for at least 4 hours before walking on it. Wait 24-48 hours for full traffic exposure.

What is the difference between stair nose and overlap stair nose?

The main difference between a stair nose and an overlap stair nose is their design and installation. A stair nose, also known as a flush stair nose, provides a smooth transition between the flooring and stair edges, creating clean lines and a streamlined appearance. It is typically installed during the initial construction of the staircase.

On the other hand, an overlap stair nose extends past the edge of the stair tread to cover the seam between the flooring and stairs, and it is often used as a retrofit option for staircase renovations or replacements.

What are the different types of wood nosing?

The different types of wood nosing include:

  1. Hardwood Species: Wood nosing is available in various hardwood species such as Oak, Cherry, Maple, and Walnut.
  2. Shapes: There are different shapes of wood nosing, including no overhang, square edge, half-round, and full-round nosing.
  3. Specialty Options: Some specialty options include bullnose stair nosing, aluminum stair nosing, anti-slip stair nosing, and single or double channel stair nosing.

What is the difference between a tread and a nosing?

The main difference between a tread and a nosing is that the tread is the horizontal surface of the stair that you step on, while the nosing is the portion of the tread that overhangs the front of the riser.
