Rocky 75 series vacuum
doors and windows
It does not dew at 70 degrees below zero. The ultra-low dew point gives the door and window the visual effect.
There is no condensation problem in Rocky75 series, and its high thermal resistance also greatly reduces dew point on the surface.
Surface stress and particle size conform to toughened glass standard and pass many safety tests such as wind pressure and impact performance.
Rocky 75 series adopts unique low temperature sealing technology, fully retains the safety characteristics of smooth glass, such as high strength, impact resistance, even if the glass is broken, its honeycomb-like fine particles are not easy to hurt people.
The U value can be as low as 1.0W/ (.K), and the heat insulation effect of the Rocky 75 series is more than that of the brick wall of 1.5m thick.
The insulation effect of Rocky75 series is over 1.5m thick brick wall. Its heat insulation performance is 2-4 times that of hollow glass and 6-10 times that of single glass. Its performance can meet the international requirements for heat transfer coefficient of door and window glass in passive rooms.
Noise reduction and noise reduction
Even in downtown areas, it is like setting up a library.
Rocky 75 series of high vacuum chambers effectively block the sound propagation, its sound insulation effect is far better than the hollow glass, especially for reducing the penetration of strong low and medium frequency noise (such as traffic noise, construction noise) effect is remarkable.
