Warminster’s panelized FRP enclosures provide a customizable and transport-friendly solution for larger footprints, confined delivery paths, or projects requiring complex interior layouts.
Built from reinforced fiberglass panels and assembled onsite, these enclosures offer the same corrosion-resistant performance as our molded shelters—with greater configuration flexibility.
Panelized FRP structures are commonly used in:
The modular design allows installation where one-piece shelters cannot be transported or where interior space must be more carefully arranged.
Each enclosure is constructed from hand-layup FRP panels that interlock and bolt into a rigid, stable structure. Benefits include:
Once assembled, panelized enclosures provide long-term protection equal to a molded structure.
Panelized systems are highly adaptable and can be configured to support a wide variety of equipment layouts and environmental requirements. Available options include:
Panelized construction makes it possible to scale up to larger applications without sacrificing durability or corrosion resistance.

Warminster’s panelized enclosures are manufactured using materials that meet ANSI/AWWA F101 standards for FRP construction. When required, we also build to:
Buy America / Build America (BABA) requirements
American Iron & Steel (AIS)
Project-specific engineering specifications
These compliance capabilities help ensure our structures are eligible for municipal funding and compatible with regulatory guidelines.
