Enough to put it in the drawing set.
Section 07 46 00. The spec, the objects and the assembly, without a sales call in between. Test reports appear here the day the lab issues them and not one day earlier.
Where the panel sits.
| Layer | Material | Nominal |
|---|---|---|
| L1 | LexPanel mineral cladding | 8 mm |
| L2 | Rainscreen furring | 3/4 in |
| L3 | Weather-resistive barrier | — |
| L4 | OSB sheathing | 1/2 in |
| L5 | Framing and insulation | 2×6 |
| L6 | Gypsum board | 5/8 in |
Lexstone replaces the cladding layer only. Everything behind it is your detail, unchanged.

Because the fire testing is still in progress, the defensible way to specify Lexstone right now is by composition and by performance-on-issue: name the mineral panel, require the report at submittal, and hold the approval until it exists.
We would rather be specified carefully than specified on a claim that has not been earned. If a project cannot wait for the reports, say so and we will tell you plainly whether to use something else.
What the panel is
Diatomaceous earth, an inorganic binder, and what that actually means on a wall.
The material →Fire performance
Non-combustible by composition. Every standard, and its current test status.
Fire performance →Installation
Circular saw, siding nails, the fastening schedule your crew already uses.
