🌟 Key Feature

product-1400-1400
Superior Waterproof & Hydrophobic Surface

Designed for outdoor exposure, our fabric surface is treated with a specialized hydrophobic coating. Rainwater beads up and rolls off instantly, preventing moisture absorption and ensuring the curtains dry quickly after a storm, effectively inhibiting mold and mildew growth.

💧 Double Composite UV-Shield Technology

The Double Composite process bonds a UV-reflective layer to the 375g polyester base. This structure blocks 100% of scorching sunlight and harmful UV rays, protecting your patio furniture from fading and reducing the temperature of your outdoor seating area by up to 10°C.

🔥 Wind-Resistant Heavyweight Build

At 375g/sqm, this is one of our heaviest outdoor textiles. The high-mass density provides a superior "heavy drape," preventing the curtains from flapping excessively in the wind, which is a common issue with lighter outdoor fabrics.

🏡 Extra-Wide 280cm Seamless Coverage

The 280cm width is optimized for large outdoor structures like pergolas and decks. It allows for expansive, seamless panels that provide a professional, high-end look without the structural weakness of stitched seams.

FAQ

Q1: Will these curtains fade if left in direct sunlight all summer?

A: No. We use high-grade UV-stabilized dyes and a Double Composite coating that reflects UV radiation. Our outdoor series is tested for high color fastness (Grade 4.5+), ensuring the vibrant color remains intact even under intense sun exposure.

Q2: Are these curtains suitable for rainy climates?

A: Absolutely. The waterproof coating prevents water from soaking through the fibers. For best results in heavy rain, we recommend hanging the curtains with a slight tension or angle to allow water to run off freely.

Q3: Can I use these for indoor spaces as well?

A: While designed for the outdoors, many clients use the 375g series for sunrooms or south-facing large windows because of its incredible heat-shielding properties and heavy-duty durability.

Q4: How do I clean bird droppings or tree sap off the fabric?

A: For most outdoor debris, a garden hose is sufficient. For tougher stains like sap, use a soft brush with mild soap and lukewarm water. Avoid bleach or harsh chemicals to maintain the waterproof coating's integrity.

Q5: Is the "Double Composite" backing white or the same color as the front?

A: Typically, our outdoor composite backing is off-white or light grey to better reflect solar heat. However, we can customize the backing color for large-scale contract orders to match your specific design requirements.
