Flexible, Modular Protection for Larger Installations

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.

Designed for Demanding Industrial and Municipal Environments

Panelized FRP structures are commonly used in:

  • Water and wastewater treatment facilities
  • Chemical feed and storage systems
  • Electrical and mechanical equipment rooms
  • Large pump stations and lift stations
  • Remote or difficult-to-access sites

The modular design allows installation where one-piece shelters cannot be transported or where interior space must be more carefully arranged.

Modular Construction, Engineered for Strength

Each enclosure is constructed from hand-layup FRP panels that interlock and bolt into a rigid, stable structure. Benefits include:

  • Easy delivery to tight or restricted sites
  • Larger available footprints and custom dimensions
  • Reinforced wall and roof panels for strength and durability
  • Corrosion-resistant construction for harsh chemical environments
  • Fast assembly with detailed installation guidance

Once assembled, panelized enclosures provide long-term protection equal to a molded structure.

Built to Your Specifications

Panelized systems are highly adaptable and can be configured to support a wide variety of equipment layouts and environmental requirements. Available options include:

  • Insulation: 1" standard, with optional 2", 4", or 6" insulation
  • Door Options: Single, double, or roll-up doors
  • HVAC: Heaters, fans, vents, and full HVAC packages
  • Electrical: Lighting systems, wiring, breakers, convenience outlets
  • Partitions: Add internal walls for separated rooms or equipment zones
  • Custom Footprints: Build to engineered dimensions or site-specific designs
  • Color Options: Exterior gelcoat colors available

Panelized construction makes it possible to scale up to larger applications without sacrificing durability or corrosion resistance.

Certified Materials and Regulatory Compliance

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
