The S1E retractable screening system combines the company’s insect screen with a privacy blind. For summer days, the blind can be pulled out to block solar heat gain; in winter, it can help retain the home’s heat at night. The shade, made of tightly woven PVC fiberglass mesh, is available in privacy or shade fabrics for varying levels of translucence. The screen and blind slide horizontally along separate tracks; a shock-absorption system prevents the screens from being damaged if a person or pet walk into them. 866.255.0008. www.centorarchitectural.com.
