Slate Cladding
Slate Cladding —
Natural Stone for Every Facade
Transform exterior walls with the permanence of natural slate. Newmont's cladding system uses QWIK Slate™ hook strips and an HDPE interlayment panel — durable, architecturally refined, and built without the weight of traditional masonry.

Slate Cladding Installation
Aug 3, 2016
Bob Williams introduces Newmont Slate Company's Slate Cladding Installation Process which utilizes QWIK Slate™ hook strips and HDPE interlayment panel.
QWIK Slate™ Hook Strips
Stainless steel hook strips provide secure, concealed attachment for each slate piece — no exposed fasteners.
HDPE Interlayment Panel
High-density polyethylene panel creates a drainage plane and thermal break between the slate and the wall substrate.
Ventilated Facade
The system creates a ventilated cavity that manages moisture, reduces thermal bridging, and extends the life of the building envelope.
Any Substrate
Installs over wood framing, concrete masonry, steel stud, or existing cladding with appropriate substrate preparation.
Six Steps to a Finished Slate Facade
A precise sequence of substrate preparation, panel installation, hook placement, and slate hanging creates a finished facade that will endure for generations.
Substrate Assessment
The wall substrate is inspected and prepared. Sheathing, waterproofing membrane, and any required blocking are installed or verified.

Hook Strip Layout
QWIK Slate™ hook strips are positioned horizontally across the panel at the correct course spacing for the selected slate size.
