Fiberglass Roof Deck Systems – Professional Waterproof Roofing Solution

Product Overview

Fiberglass Reinforced Plastic (FRP) roof deck systems provide waterproof protection and durable performance for commercial and residential applications. These lightweight, corrosion-resistant panels offer an alternative to traditional roofing materials, delivering seamless waterproofing and structural strength.

As a pultruded profile manufacturer, we produce fiberglass composite products for construction projects requiring corrosion-resistant materials.

FAQ

What are the standard panel sizes for fiberglass roof deck?

Lengths 12′, 20′, 24′ (custom available). Widths 26″ corrugated, 36″ plank, 44″ membrane. Thickness 1.0-2.0mm sheets or 1/4″-2″ boards. Profile 6.0 x 2-1/8″ or 8.0 x 3.5″.

What is the fire rating of fiberglass roof deck?

ASTM E84 Class 1 flame spread ≤25 (Steiner Tunnel Test). Vinyl ester resin with 50% glass fiber content provides fire resistance for commercial roofing applications.

What weight per square foot?

16 oz/sq.ft (6.0×2-1/8″ profile) or 21 oz/sq.ft (8.0×3.5″ profile). Much lighter than steel decking while providing structural support for single-ply and built-up roofing.

Is fiberglass roof deck corrosion resistant?

Yes. Highly resistant to moisture, salt spray, chemicals, and atmospheric corrosion. Suitable for coastal, chemical plant, wastewater treatment, and agricultural roofing applications.

What roofing systems are compatible?

Single-ply TPO, PVC, EPDM membranes. Built-up roofing (BUR), modified bitumen, standing seam metal. Requires 1/4″ per foot slope for proper drainage. Compatible with plywood/concrete/steel substrates.

How is fiberglass roof deck installed?

#14 deck screws with SB2 grommets at 12″ o.c. into purlins. 1/16″ side lap with butyl tape sealant. Flashing/trim secured with same fasteners. Slope minimum 1/4″ per foot.

Does fiberglass roof deck support foot traffic?

Yes. 36″ plank panels provide walkable surfaces for maintenance access. Corrugated panels support roofing equipment up to 300 psf. 3-6 layer systems for regular/heavy foot traffic.

Are fiberglass roof decks UV resistant?

Yes. UV stabilized resin maintains properties under prolonged sunlight exposure. Topcoat options available for additional protection. Long service life with proper installation.

Why Choose Fiberglass Roof Decks?

Our fiberglass roof deck systems deliver proven performance in demanding applications where traditional materials may degrade. The combination of lightweight construction, waterproofing, and corrosion resistance makes them a suitable choice for projects requiring durable roofing solutions.

Suitable for projects requiring:

• Long-term waterproof protection
• Low maintenance solutions
• Corrosion-resistant materials
• Lightweight structural systems

Professional installation recommended for optimal performance and warranty coverage.
