With steady growth in the furniture and upholstery markets with Foam Welt Cord and other products, DAPA found that a slightly different raw material mix and a few changes in the manufacturing process could open an entirely new market for them. Thus, DAPA Foam Spline was born. Foam Spline was totally new to the window and screening market but by proving the product is easier to use and better than most products on the market, DAPA Products basically changed an entire industry. DAPA Foam Screen Spline has helped to reduce the stress of screening and now is the favored choice for many major manufacturers.
