Hollow LOW-E glass

Hollow LOW-E Glass (Low-Emissivity Hollow Glass) is a high-performance energy-saving glass unit that integrates the thermal insulation of hollow glass with the radiation-blocking capability of Low-E coatings—redefining energy efficiency, comfort, and sustainability in modern architecture, solving the flaws of traditional hollow glass: high heat loss/gain, poor UV protection, and limited adaptability to extreme climates. Its core advantage lies in the integrated composite structure: two or three panes of glass (float, tempered, or laminated) separated by aluminum warm-edge spacers (filled with desiccant to absorb moisture) to form an airtight hollow cavity (6–20mm, optionally filled with argon/krypton inert gas), with a micro-thin Low-E coating (silver-based or titanium dioxide film) applied to the inner surface of the glass panes (to avoid wear). This coating reflects 70–90% of far-infrared radiation (heat) while allowing 70–85% visible light transmittance, delivering a 15–20 year serv…
