.2Indicate elevations, profiles, dimensions and thickness of panels.

.3Indicate location and detail of joints including joints necessary to accommodate thermal movement.

.4Show fastening and anchoring details.

.5Coordination Drawings: For [enclosure systems] [and] [gates] elements that house items specified in other Sections. Show dimensions of housed items, including locations of housing penetrations and attachments, and necessary clearances

1.6LEED SUBMITTALS:

.1Product Data for CreditMR4: For products having recycled content, documentation indicating percentages by weight of postconsumer and preconsumer recycled content. Include statement indicating cost for each product having recycled content

1.7PRODUCT DELIVERY, HANDLING AND STORAGE

.1Protect finish and edges using a plastic film adhered to prefinished components in accordance with manufacturer’s recommendations.

.2Store components and materials in accordance with manufacturer’s recommendations.

1.8WARRANTY
