The Exclusive Home Forest Hill curtain panel pair features a linen-look room darkening blackout fabric lined with Thermax blackout technology, and an allover branch motif that offers an elegant look for your windows. These curtains help block harmful UV rays from entering your home and prevent cold or heat transfer from the outside, increasing the energy efficiency of your home. Hang using the grommet top treatment which fits a curtain rod with a diameter of up to 1-5/8". For proper fullness, they should measure 2-3 times the width of your window. Hand wash only.
