Try-Ply is a washable, durable, flexible woven poly material. Featuring a black and white side, each poly coated, this material serves as an attractive and suitable ceiling and even sidewall covering for your poultry houses and other applications. Use the Tri-Ply green strapping with staples to secure in place along ceiling rafters and sidewall studs. Tri-Ply tape is used to patch the material in the event of a puncture as well as seal around bracing, vents, and other areas where Tri-Ply is manipulated during installation and repair.
