  5. Rav Ovadyah Yosef in Chazon Ovadyah (pg 1-5) and Rav Shlomo Zalman Aurerbach in Halichot Shlomo (Sukkah 7:1 pg 97) hold that plastic curtains that sway in the wind even slightly are unfit for walls of a Sukkah. However, Rav Moshe Feinstein in Sh”t Igrot Moshe 5:40 permits if the curtains are thick and there’s poles.
  6. Rama 626:1 writes that in all cases one should avoid building one's sukkah under a tree or roof. Mishna Brurah 626:1 and Aruch HaShulchan 626:1 explain that it's best to build the Sukkah under the open sky. So rules Chazon Ovadyah (Sukkot pg 11). However, after the fact, Aruch HaShulchan 626:1 writes if it's built under a roofed area it's unfit, but if it's built under a tree there is a discussion about when it is fit. S"A 626:1 (according to Biur Halacha D"H VeYesh, Mishna Brurah 626:10 and 11) rules that a sukkah under branches of a tree is fit only if it fits three requirements (See S"A with Mishna Brurah 626:10 and 11). (1) Among the branches of the tree there is majority of sun and minority shade (2) the there is less than four tefachim of tree branches over the sachach, and (3) there is a majority of shade from the kosher sachach and a minority of shade even without the tree branches (and even so the sachach under the tree branches itself is unfit but the rest of the sukkah is fit).
  7. Sh"t Igrot Moshe 5:39(4) writes that it's permissible to cover the Sukkah with a plastic sheet on Shabbat and Yom Tov without an issue of Boneh by making an Ohel nor the issue of muktzah.
