Fiberglass Casting Tape

Fiberglass casting tape, also called fiberglass cast tape or orthopedic cast tape, is a lightweight, durable, and water-resistant material used to create a modern fiberglass cast. It's the modern alternative to traditional plaster casts, offering superior strength while being significantly lighter and more breathable.

Key Benefits:

• Lightweight & Strong – Up to 4x lighter than plaster while maintaining excellent rigidity.
• Water-Resistant – Can get wet briefly without compromising the cast integrity (with proper padding and cast care).
• Fast Setting – Sets in 3–5 minutes and fully cures in around 20 minutes for a synthetic fiberglass cast.
• Breathable – Open weave design allows air circulation for patient comfort.
• Radiolucent – Allows for clear X-ray imaging without cast removal.
• Available in Multiple Colors – Patient choice improves compliance, especially with children.

Common Applications:

• Fracture immobilization with fiberglass cast tape.
• Post-surgical support.
• Orthopedic corrections and deformity management.
• Sports medicine and athletic injury casting.

Our fiberglass casting tape is trusted by orthopedic professionals, emergency departments, and sports medicine clinics worldwide. Each roll of medical casting tape is individually wrapped to maintain freshness and ensure consistent performance.

Fiberglass Casting Tape – Quick FAQ

What is the most common size of fiberglass cast tape?

For most adult short arm casts, 3-inch fiberglass cast tape is the most common size. For adult lower-leg or long arm casts, 4-inch rolls are typically used.

Do you carry different fiberglass cast tape colors?

Yes. OrthoTape Premium fiberglass casting tape comes in multiple solid colors and patterns, so patients can choose a cast color that fits their style. Techform and McKesson fiberglass casting tapes are also available in core medical colors.

Is fiberglass casting tape waterproof?

Fiberglass casting tape itself is water-resistant, but the padding underneath is usually not waterproof. For true waterproof or swim casts, use a waterproof cast liner under the fiberglass cast tape. You can find waterproof cast options in our dedicated waterproof cast section on OrthoTape.
