Description:
The 3B ShellGuard Liner is a lightweight, breathable and water-repellent fabric liner designed to protect foam inserts from moisture, mould, mildew, oil and stains. Made from non-PFAS PET fabric, it provides a soft-touch protective barrier while delivering 25–40% greater moisture repellency than the industry standard.
Designed to help reduce foam compression and extend the life of cushions and upholstered products, 3B ShellGuard maintains its performance with minimal strength loss when exposed to UV rays and heat. Its high-strength woven construction provides excellent tear resistance, making it suitable for demanding outdoor, marine, commercial and residential applications.
Ideal for outdoor cushions, pillows, furniture, seat cushions and seat backs, the liner can be used beneath woven or vinyl upholstery materials. It is suitable for pattern cutting and can be sewn or applied using sonic bonding.
Special notes:
Sold by the full roll or half rolls only.

By choosing 3Beaches, you’re selecting textiles that not only perform beautifully but are also crafted with mindful practices that reduce environmental impact.
Please note: Fabric samples are provided to showcase material quality, pattern scale, and weave detail – they are not intended for exact colour matching purposes. Due to the nature of textile production, slight variations may occur between batches.
To ensure continuity, we recommend ordering the full required meterage in one purchase, as fabric cut from different rolls may present subtle variations in pattern alignment and colour tone.
