Key Highlights
- The new 842,000+ sq ft Oklahoma City Aircraft Facility features a durable 115-mil Carlisle SynTec FleeceBACK® TPO roofing system engineered for very severe hail (VSH) and extreme weather.
- The roofing assembly includes InsulBase® polyiso insulation, EcoStorm VSH coverboard, and OctaGuard XT weathering TPO and meets strict hail, windstorm, and performance standards.
- Installation was completed 45 days ahead of schedule, supported by fast-curing adhesives and winter-ready heated application technology.
Construction began in 2023 on a massive warehouse designed to safeguard high-value aircraft engine components, including parts used in F-35, F-22, C-17, and other military aircraft.
The new Oklahoma City Aircraft Facility spans 842,000 square feet of storage area and 86,000 square feet of office space, requiring a roofing system capable of exceptional protection and reliability.
Because the facility houses sensitive and mission-critical equipment, its builders selected the proven durability of Carlisle SynTec FleeceBACK TPO, known for long-term performance, superior weatherability, and energy efficiency. This choice aligns with modern construction industry standards for resilience and lifecycle value.
Engineering a Roof for Severe Weather and Long-Term Performance
The roofing assembly is built to withstand extreme conditions. It begins with InsulBase® polyiso insulation placed over the steel deck, followed by a half-inch EcoStorm VSH coverboard, specifically rated for very severe hail impact. It is crucial for an exposed, large-scale industrial roof.
On top sits the star component: a 115-mil Carlisle SynTec FleeceBACK TPO membrane enhanced with OctaGuard XT weathering technology. This membrane offers superior protection against punctures, hail, and UV exposure, outperforming standard 60-mil TPO alternatives.
Winter-Ready Installation Technology
Roofing crews used Carlisle’s Flexible FAST™ Adhesive, applied using heated spray rigs to maintain performance in cold temperatures. This technology enabled rapid progress, at times installing more than 25,000 sq ft per day-ultimately completing the project 45 days earlier than projected.
Why This Roofing System Matters
For a facility storing sensitive aircraft engines and parts, including those used in critical military aircraft, roof integrity is not just about rainproofing. It’s about safeguarding expensive and mission-critical inventory from weather damage, water infiltration, hail, and long-term wear and tear.
By selecting Carlisle’s FleeceBACK TPO system, the developers made it deliver the following by creating a protective “envelope” for the warehouse that meets high wind, hail, and fire standards.
- Severe hail and windstorm resistance
- Strong thermal insulation
- Long-term waterproofing
- Reduced lifecycle maintenance costs
Moreover, the efficiency of installation even under winter conditions demonstrates that advanced roofing systems can be deployed quickly without sacrificing quality. This supports modern construction industry demands for durability, speed, and operational security.
