Shade Cloth 30% Black Extra Strength Mono Filament

Brilliant Product

Needed to cut heat through a large skylight — not a greenhouse, but the same problem. Two layers of 30% instead of one layer of 50% gives better solar reduction while keeping the view open and the light natural. Build quality is exactly what you'd expect from Bootstrap Farmer: solid, holds its shape, no sagging. UV and heat resistance are spot on. Thermal improvement was immediate. Highly recommend.
