Selecting Suitable Insulating Windows and Doors Based on Heat-Transfer Principles (Part III): Vacuum Insulating Glass Systems for Insulating Windows and Doors

Insulating Glass Unit Systems for Insulating Windows and Doors

Heat transfer through a VIG system also consists of the following two parts:
Spectral-optical performance: transmission, reflection, absorption, shading, visible light and total solar transmittance. Model boundary: solar radiation only, with outdoor and indoor reflectance assumed to be zero.

Thermal performance: residual-gas heat transfer, radiative heat transfer and solid heat transfer. Boundary condition: no solar radiation in the thermal calculation.

Thermal Conductivity 0.012 W/(m·K), Resilience Coefficient 0.48: LNG Elastic Blanket Performance Explained Through Storage Tank Design

High‑resilience cryogenic insulation for LNG storage tanks

At coastal LNG receiving terminals, the massive storage tanks stand like fortresses guarding energy security. Storing LNG at -162℃ safely for decades takes far more than a strong shell. Today, we look inside this steel giant to see how its structure drives the extreme requirements for cryogenic insulation—and why a seemingly soft elastic blanket is critical to system sa...

100mm Down to 20mm — and More Energy-Efficient? Premium RVs Are Switching to Fumed-Silica VIPs

Gain Extra Living Space Without Compromising Thermal‑Insulation Performance

Your RV insulation is already 100mm thick. So why is it still freezing inside in winter, and basically an oven in summer? Because piling on thickness doesn’t magically give you “warm in winter, cool in summer.” Sometimes the material itself has simply hit its limit. For premium RV insulation upgrades, fumed-silica vacuum insulation panels are getting serious attention...

The Furnace Heat Is Still Intense 30 Metres Away—The Insulation Challenge in a Steel Mill Control Room

Vacuum‑based insulation against harsh furnace radiant heat

Why is a steel mill control room still hot and energy-hungry when the air conditioning runs all year? The furnace is 30 metres away. There is a wall in between. And a pane of glass. The air conditioning runs 24 hours a day. Yet the moment an operator moves close to the glass to observe the furnace— a wave of heat hits them. The problem is not an undersized air condit...
