Sukkot - Mosquito Netting

Mosquito Netting for a Sukkah

While there are opinions which forbid the use of netting over the schach of a sukkah (e.g. Aruch laNer), Rabbi Moshe Feinstein did permit netting, under the following conditions:

1. While netting can be place either above or below the schach, it is better to put it OVER the schach. This is done so that the netting will not serve as a "support" for the schach ("davar ha'ma'amid).

2. The netting should be open enough that the openings should be more than the threads which "criss-cross" the netting. This is necessary so that more sunlight can penetrate the netting than the shade caused by the netting ("chamta meruba mi'tzilta")

The netting does not have to produced specifically for Sukkot and may be purchased at any store.
