Advancing Alternatives offers reinforced woven poly and fabrics for ventilation curtains that are designed to improve strength and light transmission. Our clear covers provide more direct sunlight (compared to the matte finish of other woven polys), while still diffusing approximately 30 percent total light. Total light transmission is 87 percent, which is comparable to most greenhouse covers that are not reinforced.
