Window with 90 degree controscopic joining method from normal market.

This photo clearly shows the poor results of this type of connection: the moisture shifts that are under construction cause wooden support movements such as these to alter the size resulting in opening. Note the remarkable dimensional diversity of the crossbar with respect to the upright.

ICSA has studied and solved this problem with 45 ° joining technology

This procedure enables the uprights and crossbars to be drawn, giving the maximum connection and stability, obtaining non-opposing continuous fibres to avoid cracking and dimensional changes. The stability and the aesthetic appearance are thus safeguarded throughout the life of the window, which is also supported by the use of water sealing of the last generation, guaranteeing the user no durability problems.

All this confirms ICSA's belief:
