Centor’s award-winning retractable Screen & Shade Systems are designed to be there when you need them but hidden when you don’t want them. Today’s residential home designs have made bi-fold doors and other large format doors become the norm. The question becomes what to do when you need a little privacy, want to manage sun glare or simply keep the bugs out? Centor’s products are designed to provide a solution to these questions and work alongside most doors and windows on the market today.
