Fumed Silica VIP
This series combines a fumed-silica core with high-performance SNG barrier film. Use the panel specification alongside the complete insulation layout, particularly at joints, corners and penetrations.

Core, envelope and panel form
The black or gray fumed-silica core is sealed in a silver or white high-performance film. The specified form is rectangular with cut corners. Confirm the geometry and protected edge zone in the project drawing.
Technical specifications
Values below apply to the fumed-silica series, not to fiberglass or lightweight VIPs. Conductivity is also shown in W/(m·K) to simplify specification matching.
| Property | Specification |
|---|---|
| Thermal conductivity λ | ≤ 4.5 mW/(m·K) = ≤ 0.0045 W/(m·K) |
| Panel density | 190–220 kg/m³ |
| Thickness | 10–45 mm; ±1 mm |
| Service temperature | −80 to +85°C |
| Compressive strength | 150–200 kPa |
| Specific heat capacity | 0.882–1.321 kJ/(kg·K) |
| Barrier film | SNG Film |
Dimensions and tolerances
Specify finished panel size and shape, rather than cutting panels to fit on site. Allow for installation tolerances in the surrounding assembly.
| Property | Range | Tolerance |
|---|---|---|
| Length | 150–800 mm | ±3 mm; ±5 mm for custom shapes |
| Length | 800–1200 mm | ±5 mm |
| Width | 135–800 mm | ±3 mm; ±5 mm for custom shapes |
| Thickness | 10–45 mm | ±1 mm |
Design for the complete assembly
For façades, refrigerated enclosures or composite panels, provide the full layer build-up, operating temperature and humidity, mechanical loads and expected service life. Joint heat flow, facing layers and long-term performance should be evaluated for that assembly.
