You know before the warm edge technology,
The dominant spacer is the aluminum spacer,
The advantage of aluminum is that it
Low prices,
Good verticality,
Distortion resistance and smooth smooth surface can ensure good water tightness and air tightness.
But it also has an unavoidable disadvantage, which is poor insulation,
Poor insulation performance of spacer is an important reason for the failure of insulating glass and the dew or mildew on the inner surface.
Because of its good thermal conductivity, the inner surface temperature of insulating glass is lower than that of the central part of insulating glass.
Not only does this create a heavier summer load inside,
The loss of heat in winter increased,
And it creates a small area of convection in front of the window, reducing comfort inside,
In serious cases, condensation will form on the inner surface of glass, which directly threatens the sealing performance of sealant of insulating glass.
Such as a long time of condensation will cause the failure of insulating glass.
At present, most of the failure of insulating glass is caused by the failure of sealant, and in addition to the poor quality of the glue or the wrong use occasions, because the insulation effect is not good condensation is also an important reason.
With the emergence of warm edges
Its extremely low thermal conductivity
Raised the edge temperature of insulating glass,
The anti-condensation performance of insulating glass is greatly improved.
The use of warm edges effectively reduces the heat transfer coefficient of the whole window.
Outdoor heat is not easily transmitted indoors,
Reduce indoor cooling loss
So as to achieve the effect of energy conservation and environmental protection.
Air tightness and water tightness are greatly improved
Greatly reduce the leakage rate of insulating glass.
