KAPIPRO^® KAPILLARSTOPP Avoid water damage in the metal roof

What is the capillary effect?

The capillary effect is also called the capillary effect. The capillary effect describes the behaviour of liquids when they come into contact with sufficiently narrow tubes, crevices or cavities in solids. Since the weight of e.g. water in narrow cavities is very low, capillary force prevails over gravity. Which is why trees allow water to rise from their roots up to 100 metres. This is exactly the principle that works when rainwater and melting water are drawn upwards between two metal surfaces. In our case: the folding of the metal roof into the hooking nose upwards into the roof structure.

Why does our KAPIpro capillary profile and compression tape help to interrupt the capillary effect?

The KAPIpro capillary profile interrupts the capillary of the metal roof at the eaves and thus physically cancels out the capillary effect. Due to its weight, the water no longer overcomes gravity and drips back into the gutter. The Compriband helps to eliminate the capillary effect in the lower part of the double standing seam, in the area of the eaves. According to the current state of the kind, the double standing seam may be sealed in the upper part of the seam with a narrow Compriband. However, this does not prevent the suction effect of the water in the lower area of the standing seam in the eaves area. Applying our Compriband helps to prevent capillaries from forming in this area over the entire height of the standing seam.
