Core Technology Behind Fire-Resistant Vermiculite Board
Thermal Insulation Functionality Explained
Vermiculite's layered silicate structure expands when heated, creating microscopic air pockets that:
- Slow heat transfer by 40-60%
- Maintain thermal barriers up to 1,200°C
- Prevent structural warping in fireplace surrounds
Enhanced Safety Mechanisms
Vermiculite achieves non-combustible certification through:
- Chemical inertness below 1,300°C
- Low smoke emission during fire events
- Thermal buffering with 6-hour fire ratings
Advanced Material Formulation
Optimized manufacturing ensures:
| Parameter | Performance Impact |
|---|---|
| Binder concentration | Controls structural integrity |
| Exfoliation ratio | Determines insulation efficiency |
| Density profile | Balances load-bearing & insulation |
