The edge strongly influences the total performance. With a warm-edge spacer a reduction on the Uwindow of 0,1 to 0,2 W/(m2.K) for standard sizes can be obtained.
The edges of the insulating glass and the window are the weak links in the total performance. The smaller the glazing, the bigger the influence of the edgeseal of the insulating glass. Especially with Trisolide® glazings a warm-edge is recommendable and enables a larger contribution to the decrease of the Uwindow performance (a reduction is possible up to 0,4 W/(m2.K). With Isolide® this results in an increase of about 6 degrees with a wooden window. Condensation on the edges of the glass will then be avoided.
The standard spacer used is black which gives an attractive look to the glazing. Other standard colors are available upon request.
