10× the life from your blast cabinet window.
BlastGuard DLC replacement windows are coated with a hardened diamond-like carbon layer that shrugs off aluminum oxide, garnet, and steel grit — so you change glass less, blast more, and keep your operators seeing clearly.
Why operators switch to BlastGuard
One coated window outlasts a stack of replacements — and pays for itself the first month you stop swapping glass.
10× lifespan
DLC's Mohs-9 hardness rivals sapphire. Standard glass pits in hours under garnet or aluminum oxide — BlastGuard runs for months.
Stays crystal clear
No frosting, no haze, no squinting. Operators keep full visibility of the work piece end-to-end.
Drop-in replacement
Cut to your cabinet's exact window opening. Same thickness, same gasket fit — no retrofit needed.

Borosilicate glass cut to your exact dimensions, then coated in our vacuum chamber with a 2–3 µm DLC film.
- 03
Ship & install
Arrives ready to drop in. Pull your old window, gasket, and clamps — same hardware, new lifespan.
Fits the cabinets you already own
We cut every window to order, so any rectangular opening works — including odd sizes from older or shop-built cabinets.
Standard glass vs. BlastGuard DLC
Same opening. Different physics.
| Metric | Standard glass | BlastGuard DLC |
|---|---|---|
| Surface hardness | Mohs 5–6 | Mohs 9 (near-diamond) |
| Typical lifespan (garnet/Al₂O₃) | Hours to days | Months |
| Clarity after 40 hrs | Heavy frost / pitting | Essentially unchanged |
| Cost per blasting hour | $$$ (constant swaps) | $ (amortized) |
| Installation | Drop-in | Drop-in (same gasket / clamps) |
