Stonewood Exterior Architectural Panels
Stonewood exterior panels were installed on pre-fi nished black 22ga galvanized steel over a Momentive GE silicone membrane. The steel supports were pre-notched for fl ashings to prevent build-up. The substructure is attached with #12-14 X 2” Hex Head Ultra Stainless X-3 into 20 gauge steel framing.
Panel fasteners were #12-14 X 1” Pancake Head Ultra Stainless X-3. Ultra stainless is a 410 stainless with 2% molybdenum to improve corrosion resistance and reduce electrolysis.
The fastener holes are a combination of small fi xed point holes (220 mils), slotted holes (220 by 320) and oversized round holes (320) to accommodate expansion. The layout varied by shape of the panel.
Stonewood Architectural Panels are tested to ASTM Standards with a Class A Fire Rating.
Stonewood is proudly manufactured in America with a short three week production lead time.
