WIDEST RANGE OF COLORS - with perfect weld

Wohnraum UPVC Windows are available in many different colours and timber decors

Wohnraum UPVC doors and windows are available in many different colors and timber decors and thanks to modern technology we are able to produce high quality windows with aesthetics never seen before - with almost invisible welds for all decors except white.

The new weld is perfectly flat and its strength is much greater than the standard welded joints. Gaskets in the corners maintain their softness, which increases protection and insulation against wind, noise and temperature differences.

Wohnraum UPVC windows have an almost invisible and flat weld




Unlike most Windows in Indonesia, Wohnraum Windows come with a Tilt & Turn Double function at no extra cost:

• Handle  faces down (Closed):
Window is securely locked

• Handle horizontal (Turn):
Window opens up to 180° to the inside

• Handle faces up (Tilt):
Window opens on the Top for Ventilation

TILT & TURN Double function

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.

*based on our research July 2016

Low-E Glass helps to reduce the energy usage (energy saving glazing) and is suitable for Green Building design.
