One good reason to choose plastic protective vents is safety because metal has sharp edges. Plastic vent doesn't have seams, rivets and welding. These give less potential for water to get in, or for an installer to injure themselves. What's more, plastic protective vents won't lead to more condensation with temperature changes. And also, the plastic protective vents won't corrode and rust.

Nylon yarn is a synthetic material yarn that can be made to resemble the look and feel of many natural fibers. Originally, nylon was created as a substitute for silk when the latter material became difficult to obtain. Nylon is strong, slightly stretchy, and generally cheaper than natural fiber yarns. This makes nylon good for many types of knitting projects. It is also usually easy to work with, so it may be a good material choice for beginner knitters.
