Glass isn’t just a window pane—
it’s the #1 player in thermal efficiency for modern buildings.
Why Glass Matters
As energy costs soar, aluminum window and door systems with advanced glass tech
are critical for cutting bills and carbon footprints. Glass covers up to 80% of these
systems—let’s decode its role!
1.Heat Transfer methods
Heat moves via radiation, conduction, and convection.
Summer example: Sunlight penetrates glass and heats interiors via radiation.
Touch hot glass → feel conduction. Open windows → hot airflow (convection).
Result: AC overload.
2.Glass: The Thermal Shield
Reduces winter heat loss by 30%+.
Blocks 50%+ summer heat gain.
Key to lowering HVAC costs and CO2 emissions.
3.Rolansini’s Glass Arsenal
Low-E Glass: Emissivity as lowest as 0.02 (vs. 0.84 in regular glass)
Reflects 90%+ infrared heat
Triple-Pane Dual-Cavity Glass: 3 layers + 2 dry air gaps → U-value 0.6 W/m²·K
Outperforms double-pane glass by 40%
4SG Hybrid Glass: Combines vacuum seals + gas fills for extreme climates
4.Beyond Glass: Rolansini’s 3-Pillar Thermal Strategy
Glass (Star player)
Frame Cavities (Multi-chamber + thermal break structure)
Seals (Airtight 6-layer gaskets)
“True insulation needs all three working in sync.”
