Warminster Fiberglass manufactures durable, corrosion-resistant FRP shelters and enclosures designed to protect sensitive equipment in demanding environments.
From chemical feed systems to electrical controls, our shelters deliver long-term performance where moisture, chemicals, and weather conditions make traditional materials fail.

Warminster offers two primary shelter configurations:

Fully molded structures for maximum strength, watertight performance, and fast installation.

Modular designs ideal for larger footprints, confined delivery spaces, or custom interior layouts.
Because no two applications are identical, nearly every shelter we build is customized to the project. Available options include:
Every shelter is built using corrosion-resistant FRP laminates with smooth, clean gelcoat interiors and exteriors.


Our shelters are manufactured using materials that meet ANSI/AWWA F101 performance requirements for FRP construction. Depending on the application, shelters can also be produced in full compliance with:
For municipal and industrial use, these certifications help ensure long-term performance and regulatory compliance.
With decades of experience supplying shelters for chemical, water, and wastewater applications, Warminster Fiberglass continues to deliver reliable, long-service-life structures that stand up to corrosion, impact, weather, and temperature extremes.
