Diversified Lineal Systems (DLS) introduced a new Rolling Patio Door System recently at the International Builder’s Show. The company says the product has a unique double monorail sill design, and also offers a single slider system with a matching picture window. The product, as well as all DLS systems, achieve CW ratings and are suitable for residential, architectural and commercial applications. The company also introduced an all fiberglass hinged frame and door system.
“The case for fiberglass in window and door construction is compelling—it has the thermal characteristics of upvc vinyl with the added advantages of vastly superior strength and minimal coefficient of expansion and contract,” says the company.
