🌟 Key Feature

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.
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.


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.
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.


Constructed from 100% reinforced polyester, this fabric is built to handle friction and outdoor debris. It is exceptionally easy to clean-simply hose it down or wipe with a damp cloth to remove dust, pollen, or dirt.
