Wohnraum Windows is probably the only Window supplier in Indonesia that offers Advanced Double Glazing (Low-E + Argon) as standard*.
The Low-E Glass reflects harmful Sunlight (UV-Light) and no additional Window film is needed. The Argon gas between the Glass panes reduces the thermal loss to keep your building cooler. This is a big advantage for residential (House, Apartment) and commercial (Hotel, Resort, Office) projects.
The Double Glazing with Argon gas also increases the acoustic properties of the window and makes it more soundproof.
