The baja exterior roll up shade is made of durable polyethylene fabric and comes with a 3 year warranty. The clutch and roller system makes it easy to operate and the chain can be operated on either the right or left side of the shade. The shade blocks the sun, not your view, and dramatically cools your room. The fabric also allows air to flow through while reducing the fading of carpert, drapes, furniture and floors. Great for patio doors, windows, pergolas, porches, garages and patios.
