Unfortunately the answer is no, brackets need to be securely mounted so they allow you to operate the shade.
No you cannot cut cordless bamboo roman shades.
They are not manufactured as outdoor shades so if they are placed outdoors the hardware will corrode and the weaving cord will breakdown. Also, although bamboo is used outdoors for its weather resistant nature, any natural material will eventually retain moisture and grow mold. You should look for a shade that states it is for exterior or outdoor use . Check out the All-Weather Exterior PVC Roll-up Sun Shades available on HomeDepot.com
We recommend 1/2" to inside mount.
My Dad installed them. They look great!
No, Natural bamboo roman shades do not provide privacy. In the evening when dark outside you will be able to see between the bamboo slats into the lighted home.
If they can it's above my paygrade. Sorry I couldn't help.
No these shades are not outdoor shades.
I can only comment on this particular shade and 48" is the widest these shades are available in. Please speak to your local Home Depot to see what other shades are available.
