Envelope 2000® is a composite panel for exterior use made by laminating an aluminum skin to a substrate of thermoset phenolic resin. A second aluminum skin is added as a backer and provides thermal stability and panel balance. This system is designed for use as exterior cladding on walls, canopies, fascias, and accent bands. However, Envelope 2000® is also ideal for other applications where a high end look is desired.Similar to Panel 20®, Envelope 2000® is impact resistant, water resistant, and provides ultimate smoothness in a wide variety of finishes. However, a thicker core and fully fabricated attachment systems takes this panel to the next level in exterior cladding.The Rout & Return System (RR) is a barrier system in which panels are fabricated and formed into 'pans' and then mounted onto the substrate using aluminum extrusions. All fasteners are concealed and panel joints (1/2" reveal typical) are finished with an approved sealant.
