Variable Square Notch cladding

Industrial Meets Intentional

Inspired by the bold geometry of shipping-container architecture, Variable Square Notch transforms industrial influence into a sophisticated façade. Crisp square recesses create depth and shadow, complementing glass and concrete in contemporary multifamily and mixed-use design.

Substrate Overview

FastPlank® Systems can be installed over sheathed wood-stud or steel-stud walls, metal girts, and furred concrete or masonry using the specified fastener for each substrate.

Rainscreen System

All FastPlank® systems are AAMA 508-certified pressure-equalized rainscreens. Intelligent design channels water away from the building envelope, while a 3/8" air cavity exceeds building code rainscreen requirements.

Clip & Slide™ Attachment

Patented Clip & Slide™ technology secures each plank with hidden clips spaced 16" to 32" apart. The lightweight 16' aluminum planks slide into place, and a non-ferrous carbide blade handles clean cuts on site.
