For screening windows and doors, if additional UV protection and increased shading are required, (this product) is ideal.

Except for the use of passive voice, this may be a better construct for the sentence. The correct verb tense is "are," as we have both "UV protection and increased shading."

Whether you need "is" or "are" depends on whether your subject is singular or plural, as the verb must agree in number with the subject. Use "is" with a singular subject but "are" with a plural subject.  In this case, the simplest version of the subject is "protection and shading," therefore you need a plural verb. The use of "and" links the words "protection" and "shading" into one plural subject.

" are required" in this case

I found this on the interent:

Rule 4. As a general rule, use a plural verb with two or more subjects when they are connected by and.

Example: A car and a bike are my means of transportation.

But note these exceptions:

Breaking and entering is against the law.
The bed and breakfast was charming.

In those sentences, breaking and entering and bed and breakfast are compound nouns.
