MOD-36 LINER PANEL
Create Interior Protection and A Great Look
The MOD‑36 liner is a factory‑formed metal panel installed on the inside of the wall girts and purlins to create a clean interior surface while protecting the blanket insulation. Panels can be installed at partial height based on girt spacing or extended to the full height of the wall, giving you a durable, low‑maintenance interior liner system tailored to your building’s needs.
Beautiful Protection In Every Corrugation
Choose the MOD‑36 liner system when you want faster installation, long‑term insulation protection, and a clean interior finish that holds up for years. Its durable steel surface is easy to wash, resists everyday wear, and keeps your Butler building looking sharp while safeguarding your blanket insulation. A smart upgrade for any new Butler Metal Building.
Benefits of Mod 36 Liner Panels
add panel strength
Mod 36 Metal Liner Panels feature a full 1/2‑inch‑deep corrugation that delivers a clean, streamlined appearance while providing enhanced structural strength. These panels are available in multiple gauge options from 22 to 26 gauges, allowing you to balance performance requirements, durability, and budget considerations for any Butler Metal Building project.
fast and accurate install
Every Mod 36 Metal Liner Panel and its supporting structural members can be factory‑punched for precise alignment and faster installation. Multiple fastener options are available to match your project’s aesthetic, performance, and security requirements—including the Butler Scrubolt, engineered with up to twice the pull‑out strength of standard industry fasteners.
unmatched design versatility
Predesigned and factory‑fabricated transition materials make it easy to integrate Mod 36 Metal Liner Panel with other Butler Wall Systems, conventional building materials, doors, and windows—without costly field modifications. These components ensure clean connections, faster installation, and long‑term performance, and are available in all Butler‑Cote™ finish system colors.
enhanced beauty
All Mod 36 Metal Liner Panels feature the high-quality Butler-Cote premium finish. Made with 70% Kynar 500 or Hylar 5000 resin, this incredibly durable coating restists fading and chalking to remain vibrant for years, unlike typical silicone polyester paints. The Butler-Cote finish includes a real 25-year warranty against chalking and fading with an expected life span of 45 years.

Frequently Asked Questions
Still deciding if a Butler building is right for your project? Here’s what most builders ask us before they get started.
Still have questions?
Talk to a real person. Call our Pro Desk Expert Line or request a callback.
What makes a Butler building different from other metal buildings?
Butler has been engineering steel buildings for over 125 years, and AM Star is an authorized Butler distributor, not a reseller of generic components. Every building you get through us uses genuine Butler engineered parts, backed by Butler’s manufacturing standards.
Can I customize the size and layout of my building?
Yes. Butler buildings are engineered to your exact specifications, size, use, and site requirements, whether that’s a small workshop or a large industrial facility. Our team works with you from initial design through structural engineering to make sure it fits your project.
How much does a Butler building cost?
Pricing depends on size, building type, durability grade, and site conditions, so there’s no single number that fits every project. Request a quote and we’ll get you accurate pricing fast, tailored to your specific building.
How long does the process take, from quote to finished building?
Timelines vary by project scope and current fabrication schedules. Once you request a quote, we’ll give you a realistic timeframe based on your specific building and location.
Do you handle engineering and permitting?
Yes. Every Butler building is engineered to meet local codes and structural requirements, with stamped drawings provided for permitting, backed by Butler’s manufacturing standards.
What's the difference between a Butler building and a barndominium?
A barndominium is one type of building you can build using Butler’s steel building system, combining residential living space with a metal building structure. It uses the same engineered components and durability standards as our other building types.
What if I'm not building new, I just need parts or repairs?
We also supply genuine Butler parts and components for repairs, replacements, or expansions, no need to order a full building. Browse our parts catalog or contact us directly.
How do I get started?
Request a quote and tell us about your project, building type, size, and timeline. We’ll follow up with accurate pricing and next steps, no pressure, no runaround.
