两层玻璃与一张特殊的热镜薄膜组合由双层特种隔离条分隔形成一种特殊的双中空结构，并采用双层硅胶密封。
Two pieces of glass and one suspended Heat Mirror film construct the unique dual-space structure. The insulating gaps are separated by high performance spacers, and dually sealed by sealant.
热镜优异的保温性能使温差保持在中空层的两侧，从而减少内片玻璃的热量散失或积累。
Heat Mirror's excellent insulating performance can keep temperature difference between two sides of spacing layers, thus reduce heat dissipating and accumulating on the inner surface of the glass.
