Curved Tee-Lock

Curved Tee-Lock CR-TL25 is a structural panel which is mechanically seamed during installation. The panel is a bi-directional system by design which installs in two directions from a given starting point. TEE-LOCK provides installers more control during installation over seam layout and allows symmetry of the panel area. The one piece clip allows for unlimited expansion and contraction.

Are you truly getting a warranty or is it just a glorified maintenance agreement? Is the warranty covering all aspects of your Metal Envelope system? Is it guaranteeing that your project is being installed with the best quality?
