Low-E insulated glass
LOW-E insulated glass is a product consisting of two or more panes of glass—of which at least one is LOW-E glass—spaced apart by effective spacers and sealed around the edges, creating an interlayer with a dry-gas-filled space.
Product Features
Thermal Properties
A lower U-value (thermal transmittance) yields a more pronounced effect when filled with an inert gas.
Optical performance
Depending on actual needs, you can flexibly select different levels of solar transmittance and reflectance. Sound insulation: Insulated glass typically reduces noise by about 30 decibels, and filling it with an inert gas can further lower the noise level by approximately 5 decibels on top of that.
Condensation prevention performance
The dew point can reach –40°C, ensuring that insulated glass units do not fog up.
Sealability
The aluminum frame (spacer bar) is formed in a single step, and the double-seal system—comprising butyl sealant and either structural sealant or polysulfide sealant—ensures the airtightness of the insulated glass unit and extends its service life.
