Get an estimate

Traffic noise is reduced by a total 44 dB (Rw+Ctr)

Vinduet eliminerer det meste av støyplager fra biltrafikk, fly, tog, industri og annen støy som gjør hverdagen plagsom. Trafikkstøy reduseres med hele 44 dB. Støyreduksjon fra kilder med annen frekvens er tilsvarende god.

Ingenious design – two windows in one

Built with two window sashes in one shared frame.
Outwards top swing window on the exterior. Inwards opening window on the interior – both with double glazing/sound-reducing glass.

U-value: An incredible 0.53

Thanks to the four panes of glass – in addition to the air gap between the window sashes – Magnor Silent+ has unparalleled energy-saving properties, with an extremely low U-value of 0.53. These measurements have been performed by a highly recognised and neutral institute.

A new life, without noise!

Magnor Silent+ is the right choice for all buildings with exposure to noise: Offices, hotels, schools, private homes etc. Amalie Skram upper secondary school is located right next to the busiest road junction in Bergen, and chose to install Magnor Silent+ on the façade facing the road. They are extremely satisfied with the effect of the windows.
