Clear outdoor curtains are made of industrial grade PVC. This material is extremely flexible and very strong to keep the weather out while maintaining a comfortable work environment inside. Custom made outdoor clear curtains will have a perfect fit and are designed specifically for your application. They are very inexpensive when compared to rigid walls and they have the added benefit of being able to be pulled back and stored when not in use. The heavy duty outdoor curtains come in two versions which are the standard outdoor curtains and the super duty anchor strap version. And finally, the clear curtains are the best when it comes to flexibility. They will cover any opening and prevent temperature loss.
