The Ecoshel smart shingle system consists of 45-inch–long panels of No. 1 vertical grain western red cedar shingles joined together with PVC clips. A numbering system on the panels provides a guide for vertical joints on adjacent courses to be automatically offset. A 1/10-inch–thick polyethylene bead on the back qualifies as a LEED-spec rainscreen. They can be prefinished with a semi or solid stain. MSRP is $300 to $550 per square.
