Modern apartment building with brown horizontal cladding, large illuminated windows, and balconies, photographed at dusk. — At Parc Mosaic Apartments in Boulder, Colo., Gen3 Construction replaced deteriorating composite siding with Parallel’s 6-in. aluminum cladding panels in an Espresso Walnut finish.

Parallel Architectural Products[2], a brand of Armstrong World Industries Inc.[3], reports it has earned a Miami-Dade Notice of Acceptance (NOA No. 25 1006.01) and Florida Product Approval (FPA # 47612) for cladding applications.

The approvals recognize Parallel 4-in., 6-in., 8-in., and 12-in. cladding boards as compliant with High-Velocity Hurricane Zone (HVHZ) building code requirements when installed as specified. The products are approved with a cladding-clip fastening span of up to 32 in. o.c.

A Miami-Dade NOA indicates the boards meet requirements for resistance to wind loads, water infiltration, air leakage, and debris impact. Parallel cladding and soffits comply with the Florida Building Code when installed on either 5/8-in. plywood or 5/8-in. gypsum board.
