The interior of a metal building needs protection just as much as the exterior. Warehouses, industrial facilities, retail centers, utility buildings, and other commercial structures can experience constant contact with equipment, stored materials, vehicles, and everyday activity that can damage exposed wall systems and insulation.
The Butlerib II Liner Panel provides a durable interior wall surface designed to install on the inside of wall girts and along the bottom of purlins. Depending on the building’s requirements, the panels can be installed at partial height based on girt spacing or extended to the full height of the wall.
This makes Butlerib II a practical option when a project needs a finished interior appearance while also protecting the underlying building components.

What Is a Butlerib II Liner Panel?
A Butlerib II liner panel is a metal panel used as an interior liner system within a Butler metal building.
Unlike an exterior wall panel whose primary purpose is to protect the building from outdoor weather, an interior liner panel is installed inside the structure.
Its primary functions include:
- Protecting interior wall components
- Providing a finished interior surface
- Protecting insulation
- Improving interior appearance
- Creating a durable surface in high-use spaces
- Simplifying maintenance of the interior wall system
Butler describes the Butlerib II system as suitable for installation on the inside of wall girts and along the bottom of purlins.
How Butlerib II Liner Panels Are Used
The flexibility of the Butlerib II liner system allows it to be configured according to the needs of the building.
For example, a building may use liner panels only on the lower portion of the wall where equipment, vehicles, or stored materials are most likely to cause damage.
Alternatively, the liner can extend across the entire interior wall.
The installation can therefore be tailored to:
- Building use
- Interior traffic
- Wall height
- Girt spacing
- Insulation configuration
- Desired appearance
- Protection requirements
This makes the system useful for both new construction and replacement projects.
Partial-Height vs. Full-Height Liner Panels
One advantage of Butlerib II liner panels is that they do not necessarily have to cover the entire wall.
Partial-height installation can provide protection where it is most needed.
For example, a warehouse may install liner panels several feet above the floor to protect the lower wall from:
- Forklift traffic
- Pallets
- Stored materials
- Equipment
- Carts
- General impact
Full-height installation provides a continuous finished interior surface and can offer additional protection for insulation and wall components.
The appropriate configuration depends on the building’s intended use.
Why Use an Interior Liner Panel?
Leaving insulation and structural components exposed can create a less finished interior environment.
An interior liner panel provides a defined surface between the occupied space and the underlying wall assembly.
This can improve:
- Interior appearance
- Wall protection
- Cleanability
- Insulation protection
- Long-term maintenance
- Resistance to everyday impact
For commercial and industrial buildings where the interior is visible to employees, customers, or visitors, the appearance of the wall system can also be an important consideration.
Butlerib II Liner Panels and Insulation
Insulation can be vulnerable to damage when it is exposed to active interior environments.
Forklifts, equipment, stored materials, and maintenance activities can come into contact with exposed insulation.
A liner panel creates a protective interior surface over the wall assembly.
This can help reduce direct contact with the insulation and underlying components.
However, the liner panel should be considered part of the overall wall assembly rather than a replacement for properly specified insulation.
Butlerib II Rib Profile
The Butlerib II panel features 1½-inch-deep corrugations.
The deep rib profile gives the panel a distinct appearance while adding rigidity to the panel surface.
For interior applications, this creates a structured appearance rather than the completely flat surface associated with some liner systems.
The ribbed profile can also help conceal minor surface imperfections that may be more noticeable on completely flat panels.
Interior Appearance
An interior liner system can significantly change the appearance of a metal building.
Instead of exposing:
- Insulation
- Wall girts
- Fasteners
- Structural components
- Other wall assembly elements
the liner provides a continuous metal surface.
Butlerib II’s ribbed appearance gives the interior a finished industrial aesthetic that works particularly well in warehouses, workshops, utility buildings, and other commercial environments.
Butlerib II Liner Panels for Warehouses
Warehouses are one of the practical applications for interior liner panels.
The interior walls can be exposed to constant activity from:
- Forklifts
- Pallet jacks
- Storage racks
- Shipping equipment
- Moving materials
- Maintenance personnel
A durable liner can provide an additional protective layer between these activities and the underlying wall system.
For warehouses where appearance matters, the liner also creates a more finished interior environment.
Butlerib II Liner Panels for Industrial Buildings
Industrial buildings can benefit from liner panels where interior walls need additional durability.
Manufacturing equipment, material handling systems, and maintenance activities can subject wall assemblies to regular wear.
A metal liner can provide a surface that is easier to maintain than exposed insulation or other vulnerable materials.
The appropriate panel configuration depends on the building’s specific operating environment.
Facilities with unusual chemical exposure, extreme temperatures, or specialized sanitation requirements should verify that the selected finish and panel system are appropriate for the application.
Butlerib II Liner Panels for Retail and Commercial Buildings
Interior liner panels are not limited to heavy industrial facilities.
Butlerib II can also be used in commercial environments where a durable industrial appearance is appropriate.
Potential applications include:
- Retail centers
- Equipment facilities
- Service buildings
- Utility spaces
- Commercial warehouses
- Maintenance facilities
The ribbed metal appearance can complement the architectural character of a modern industrial or commercial building.
Butlerib II Liner Panels for Retrofit Projects
Replacement liner panels can be particularly useful when renovating an existing Butler building.
Over time, interior panels may become:
- Damaged
- Scratched
- Corroded
- Denting
- Discolored
- Loose
- Difficult to maintain
Replacing damaged sections can restore the appearance and protective function of the interior wall.
A full wall replacement may not always be necessary.
If the existing system can accommodate replacement panels, individual sections can potentially be addressed based on the condition of the building.
Factory-Punched Components
Factory punching can improve installation accuracy.
Butlerib II wall panel systems and supporting structural members can be factory-punched to help with alignment and installation.
This can reduce the amount of field modification required and help maintain consistent panel positioning.
For replacement projects, however, existing field conditions should always be verified before ordering components.
Older buildings may have different structural dimensions or configurations from newer Butler systems.
Butler-Cote Finish
The Butlerib II system is available with the Butler-Cote finish.
According to Butler Metal Building Parts, the Butler-Cote finish uses a high-performance resin system designed to resist fading and chalking. The company states that the finish includes a 25-year warranty against chalking and fading and an expected service life of 45 years.
For interior liner applications, the finish contributes to the overall appearance and durability of the exposed panel surface.
The available finish should be selected based on the project requirements and desired appearance.
Cleaning and Maintenance
One advantage of a metal interior liner is that it provides a relatively straightforward surface to maintain.
Routine maintenance can include:
- Removing accumulated dust
- Cleaning dirt from the panel surface
- Inspecting for physical damage
- Checking fasteners
- Looking for corrosion
- Inspecting panel joints
- Checking areas around doors and equipment
The specific cleaning method should be appropriate for the selected finish.
Harsh chemicals or abrasive cleaning methods should not be used without confirming compatibility with the panel coating.
Impact Resistance
Interior walls in industrial buildings can experience substantially more physical contact than exterior walls.
Forklifts, carts, equipment, and stored materials can strike or scrape interior surfaces.
The Butlerib II panel’s deep rib profile contributes to its rigidity and durability.
However, no metal liner panel is immune to impact.
Severe impacts can dent panels or damage the surrounding framing and fasteners.
Where repeated impacts are expected, additional protective barriers may be appropriate.
Liner Panels and Building Insulation
An interior liner panel should be coordinated with the insulation system.
The liner can protect the insulation from interior exposure while providing a finished surface.
Depending on the wall assembly, the system may include:
Exterior wall panel → insulation → structural framing → interior liner panel
The exact assembly depends on the Butler building system and project requirements.
Proper detailing is important around:
- Doors
- Windows
- Corners
- Base conditions
- Roof transitions
- Wall penetrations
Butlerib II Liner Panels and Moisture
Metal liner panels can help protect the interior side of a wall assembly, but they should not be treated as a complete moisture-control system.
Moisture management depends on the entire building envelope.
Important components can include:
- Exterior cladding
- Insulation
- Vapor retarders
- Air barriers
- Flashing
- Sealants
- Drainage
- HVAC systems
The correct assembly depends on climate and building use.
Liner Panels Around Doors and Windows
Interior liner panels need to transition cleanly around openings.
Common openings include:
- Personnel doors
- Overhead doors
- Windows
- Louvers
- Mechanical penetrations
- Electrical penetrations
Proper trim and transition materials can help create a finished appearance and protect exposed panel edges.
Butler states that predesigned transition materials are available to coordinate Butlerib II panels with other building materials, doors, and windows.
Liner Panels Around Building Corners
Interior corners require careful detailing.
A liner panel system should transition between adjacent walls without leaving exposed insulation or unfinished gaps.
Corner trim and other transition components can provide a cleaner appearance while protecting the edges of the liner system.
The exact detail depends on the building configuration.
Base Conditions
The bottom of the liner panel is another important detail.
The base should be coordinated with:
- Floor elevation
- Base trim
- Wall insulation
- Moisture conditions
- Interior cleaning requirements
In industrial buildings, the base of the wall can be exposed to water from cleaning operations or incidental moisture.
Proper detailing can help prevent premature deterioration.
Butlerib II Liner Panels vs. Exposed Insulation
Leaving insulation exposed may reduce initial material requirements, but it provides less protection against interior activity.
A liner panel creates a finished surface over the insulation.
| Factor | Butlerib II Liner Panel | Exposed Insulation |
|---|---|---|
| Interior finish | Finished metal surface | Insulation remains visible |
| Insulation protection | Stronger protection | More exposed |
| Appearance | Clean industrial appearance | Utility-focused |
| Impact protection | Better than exposed insulation | Limited |
| Maintenance | Metal surface is relatively easy to maintain | Insulation can be more difficult to clean |
| Retrofit potential | Can replace damaged liner sections | Requires different treatment |
The appropriate choice depends on the building’s intended use, budget, and interior requirements.
Butlerib II Liner Panels vs. MOD 36
Both Butlerib II and MOD 36 are used as interior liner systems within Butler buildings.
The two systems differ in their panel profiles and installation characteristics.
The MOD 36 liner panel is described by Butler Metal Building Parts as a symmetrical rib profile designed for interior wall applications, while Butlerib II uses a deeper 1½-inch corrugated profile.
The best option depends on the existing building system, desired appearance, and project requirements.
For replacement work, compatibility with the existing installation should be verified before selecting a panel.
Measuring an Existing Butlerib II Liner Panel
When replacing an existing panel, accurate measurements are important.
Document:
- Panel width
- Panel length
- Rib profile
- Rib depth
- Panel thickness or gauge
- Fastener locations
- Girt spacing
- Base condition
- Corner conditions
- Openings
- Existing trim
Photographs of the existing liner from several angles can also help identify the correct replacement configuration.
Replacing a Damaged Butlerib II Liner Panel
A damaged liner panel does not necessarily mean the entire interior wall needs to be replaced.
Depending on the extent of damage, replacement may involve a single panel, several panels, or a complete interior wall section.
Before removing the damaged panel, inspect the surrounding structure for:
- Bent girts
- Damaged fasteners
- Corrosion
- Insulation damage
- Water intrusion
- Damaged trim
Replacing only the visible panel without addressing underlying damage can result in recurring problems.
