Benefits
Overview
The Problem: Checker Plate and Diamond Plate Metal Stairs offer an instant finished stair system. Requiring no on-site finish work to complete the walking surface. Unfortunately walking on metal only stairs creates vibration and this creates sound. That sound creates a major acoustics problem for high foot traffic stairs and a nuisance to occupants and tenants on the other side of the wall.
REMOVES SOUND COMMONLY ASSOCIATED WITH METAL STAIRS
The peel and stick mat absorbs the vibrations created by foot traffic to dampen the sound.
ALLOWS FABRICATORS TO BUILD STAIRS WITH THIN GAUGE METAL
Thicker tread plates vibrate less, however, it is costly, difficult to fabricate, and heavy. Fabricating with thinner materials offers many efficiencies; lighter stairs systems impose less weight on the building structure which offers cost savings beyond the stair system.
OFFERS ARCHITECTS, BUILDING OWNERS, CONTRACTORS COST SAVINGS
Checker plate or diamond plate stairs offer an instant finish and are most affordable to fabricate and install. However, the associated sound issue is the most common reason for stairs built using concrete or other finishes. Quiet Tread is often shop applied and resolves the sound issue immediately. The stairs are installed and are immediately ready for use. No additional trades, temporary infills, or on site finishing required.
ELIMINATES THE NEED TO BUILD WITH COSTLY PAN FILLED STAIRS
Pan filled stairs are often selected because concrete solves the sound issue. However, concrete comes at a cost: site labor, site pour, site cleanup, scheduling delays, concrete cracking, poor finish, concrete corrosion issues.
AN INSTANT APPLICATION AND STAIR SOUND DAMPENING SOLUTION
Quiet Tread was created to solve the noise issue immediately for the least amount of ownership overall cost. It is a simple peel and stick application to the underside of the walking surface, and requires minimal preparation, labor, and zero maintenance after installation. Eliminating on-site time, labor, and various trades outweighs the Quiet Tread investment.

Background
Prefabricated steel stair assemblies are commonly used in industrial, commercial, and residential applications. In some situations, stairways can be a source of noise that can adversely affect the comfort of occupants in adjacent areas. Generally, steel stairs with concrete filled pans have been considered quieter than steel tread covered stairs. However, concrete filled pans are more expensive, must be protected during construction, and can require remediation if cracked or damaged before occupancy. The purpose of the present research was to quantify the relative acoustic performance of different stair treatments under different mechanical inputs. Six different stair treatments were investigated. These included:
- Traditional concrete filled pan stairs
- Traditional steel checkered plate stairs
- Steel checkered plate stairs with proprietary use of Line-X™
- Steel checkered plate stairs with proprietary use of Quiet Tread applied to risers alone
- Steel checkered plate stairs with proprietary use of Quiet Tread applied to steps alone
- Steel checkered plate stairs with proprietary use of Quiet Tread applied to steps and risers
These six single flights of stairs were tested individually and then five were tested with accompanying landings. All stair assemblies were fabricated by the Pacific Stair Corporation with production-run details and materials. The traditional stairs (checkered plate and concrete filled pans) provide the current reference acoustic performance baseline levels. In addition to the individual flights, three landings (one checkered plate, one Quiet Tread, and one Line-X™) were tested in combination with their matching stair flights.
No standardized acoustic testing protocols exist for stair assemblies and national and international standards, including ASTM, ISO 140, British and Australian Standards were surveyed and adapted to develop acoustical performance tests of stairs and stair assemblies. Testing protocols were adapted from the following standards as they apply to this research:
- ASTM E 492-04: Standard Test Method for Laboratory Measurement of Impact Sound Transmission through Floor-Ceiling Assemblies Using the Tapping Machine
- ASTM E 2235-04: Standard Test Method for Determination of Decay Rates for Use in Sound Insulation Test Methods
- ISO 140.6-2006: Acoustics – Measurement of Sound insulation in buildings and of building elements. Part 6: Laboratory measurements of impact sound insulation of floors.
- ISO 3741: Acoustics – Determination of sound power levels of noise sources using sound pressure – Precision methods for reverberation rooms
Reverberation Chamber Description and Acoustic Characteristics
A reverberation chamber was constructed to test the acoustic performance of the stair assemblies. The chamber was designed to reject background noise, allow acoustic reverberations (exhibit low acoustic absorption), and to simulate the geometric conditions of use for prefabricated steel stairs (representative of a stairwell). The chamber floor was a cast-in-place concrete slab and j-bolts were installed to allow attachment of the stair landings. The walls and roof were wood framed with 2×6 lumber and sheathed in ¾ in. thick MDO plywood. Fiberglass insulation was placed between the studs.
Epoxy paint was applied to the sheathing to produce a hard surface. As suggested in ASTM E 492, sound diffusion panels employed in order to create a more diffuse sound field within the chamber. Two diffusing panels, also made of ¾” MDO, were hung from the ceiling of the chamber. The inside plan dimensions of the final room were 105 in. by 125 in. and the chamber was 144 in. tall. These dimensions meet the requirements of ASTM E 492 that dimensions not be ratios of small whole numbers and that the ratio of the largest dimension to the smallest be less than two. The total volume of the room was 1094 cubic feet.

Installation
Overview
Quiet Tread is a peel and stick application to the underside of stair treads and landings where foot traffic occurs. Quiet Tread must be attached to a smooth, clean, dry surface. Each edge of Quiet Tread 1-2 inches away from edges, obstructions, bends, and welds. This is to guarantee the best result, the most coverage for absorbing the most vibration to reduce sound. The product must be applied completely flat for a lasting adhesive bond.
INSTALL SHOP APPLIED DURING STAIR FABRICATION
- Important Information
- Install Quiet Tread on the unfinished underside of the metal stair tread and landing sheet.
- Inspect the stair treads or landing sheet to ensure the underside surface is smooth and free from imperfections.
- Clean and dry the surface of the stair treads or landing sheet that will receive Quiet Tread, ensuring it is free of loose mill scale, imperfections, rust, dust, moisture, solvents, or oils. The manufacturer recommends using 99% alcohol and white cloth which does not leave loose threads for cleaning.
- It is crucial that the surface is thoroughly cleaned, as adhesive bond failure can occur if not. Additionally, ensure the metal stair tread substrate is flat.
- Remember, the quality of the adhesive depends on the surface it adheres to, so correct any imperfections before proceeding with the installation.
- Install Preparation
- Begin by placing the prefabricated stair flights and landings upside down on the floor in a protected interior environment to prevent any contamination during the cleaning process.
- Ensure that the ambient temperature of the installation environment and the surface temperature of the metal fall within the range of 70°F to 120°F. If necessary, use a propane torch to heat the metal surfaces to achieve the desired temperature.
- Thoroughly clean the surfaces where the Quiet Tread will be applied. To ensure proper cleanliness, use a new cloth to verify that the surfaces are completely free of any debris or contaminants.
- Plan out the layout with markings on the steel for installing the Quiet Tread panels. Once the panel is applied onto the substrate, it cannot be moved or removed without causing irreparable damage to the Quiet Tread panel. Therefore, careful planning and precision during installation is crucial.
- Apply Quiet Tread
- Ensure all installation preparations are complete before proceeding.
- Remove the release backing from the underside of the Quiet Tread panel.
- With the assistance of another worker, position one corner of the Quiet Tread panel on the layout mark, aligning the panel with the edge of the stair tread and maintaining a distance of 1 inch from the edge.
- Starting from one end of the panel, gradually lower it onto the underside of the tread surface, taking care to avoid trapping air between the substrate and the Quiet Tread panel.
- Once the Quiet Tread panel is in position, firmly press down with hands to eliminate any air pockets.
- Applying Pressure For Adhesive Bond
- Using a commercial-grade vinyl roller. Start by rolling the panel onto the underside of the stair tread substrate from one end to the other, applying approximately 25 lbs. per square inch pressure.
- After completing the first pass, rotate the roller 90 degrees, and repeat rolling the Quiet Tread panel using ~25 lbs. per square inch.
- Proper attachment of the Quiet Tread panel to the smooth metal substrate is crucial. Make sure to roll it thoroughly to maximize the bond between the stair tread substrate and the Quiet Tread panel. The roller is used in both up-and-down and side-to-side directions.
- Cure Time
- Allow 1 hour for the adhesive to set before moving the stair into the outside environment.
- Keep the stairs dry.
- Allow 24 hours for the adhesive bond to cure.
- Finish Painting
- After the cure time, simply prime or paint the stairs and landings. No further steps are necessary.
FIELD INSTALL ON EXISTING STAIRS
Quiet Tread can be applied to existing stairs with proper preparation and installation techniques. Follow the standard steps for installing on new stairs but take extra care to ensure a strong bond.
- Surface Condition Check
- Ensure the underside substrate of the stair tread or landing is free from rust or corrosion.
- Verify that any pre-applied finish won’t peel or flake once the Quiet Tread panel is installed.
- If there are concerns, sand the substrate surface which Quiet Tread would be adhered to and clean it thoroughly before installation.
- Installation Preparations
- Install Quiet Tread panels using scaffolding underneath the stairs.
- Plan labor, occupant egress, and necessary equipment ahead of time.
- Layout Markings
- Make precise layout markings to avoid improper placement and ensure consistent application.
- Application Technique:
- Apply pressure with a commercial-grade vinyl roller immediately after placing Quiet Tread.
- Repeat rolling one hour later to ensure the bond remains intact due to gravity.
- Final Touches
- Allow 24 hours for the adhesive bond to cure.
- Visually inspect panels to ensure the bond remained intact due to gravity.
- Finish paint over the Quiet Tread panels.
- Pay special attention to sealing exposed edges with paint to protect the adhesive bond from contaminants.
Maintenance
Overview
With proper installation of Quiet Tread and regular inspection, minimal to no maintenance is required.
CARE
- Avoid using salts, deicers, or chemicals on stairs, as they can cause metal stairs to rust or corrode, thereby compromising the Quiet Tread adhesive bond.
- Stairs exposed to the elements, moisture, or water may weaken the adhesive bond.
- After installation, it is advisable to apply a finishing coat of paint to the stair system or structure where Quiet Tread has been installed. This finishing paint helps shield Quiet Tread from moisture, liquid, rust, dust, grime, or tampering by encapsulating its exposed edges and surface.
- In areas where moisture, liquid, and rust are potential issues, it’s strongly advised to protect Quiet Tread by applying a durable finish coat of paint or another suitable finish. Regularly inspect and touch up the finish coat to prevent contamination between the surface accepting Quiet Tread and its adhesive surface.
- It’s advisable to conduct regular inspections for delamination in areas where Quiet Tread is installed. In case of any concerns, reach out to National Stair Products on a case-by-case basis to address potential delamination problems before they escalate into significant failures.
CLEANING
Follow these steps to clean the underside surface of metal stairs and prevent corrosion or rust after installation of Quiet Tread.
- Remove Debris: Start by removing any dirt, dust, or debris from the surface using a stiff brush or broom.
- Use Mild Detergent: Mix a mild detergent with warm water. Apply the solution to the underside surface of the metal stairs using a sponge or cloth. Gently scrub the surface to remove any remaining dirt or grime.
- Rinse Thoroughly: Rinse the surface thoroughly with clean water to remove any traces of detergent. Make sure to rinse away all soap residue.
- Dry Completely: Use a clean towel or cloth to dry the surface completely. Ensure that there is no moisture left on the metal stairs, as standing water can promote corrosion.
- Apply Protective Coating: Optionally, consider applying a protective coating or sealant specifically designed for metal surfaces. This can help create a barrier against moisture and prevent corrosion over time.
- Regular Maintenance: Schedule regular inspections and cleaning sessions to keep the underside surface of the metal stairs clean and free from corrosion. Promptly address any signs of rust or corrosion by cleaning and applying appropriate treatments.
STORAGE
- Stack flat. Do not Lean.
- Do not remove from factory packaging.
- Store indoors in a temperature controlled environment.
- Do not expose to moisture.
- Keep away from heat sources.
