Corners may be made with the metod of pressure welding or thermoforming for types of bands: TU, TUS-1, TUS-2, TPER, Izohydrotex or TDS. The application of corners while making isolation guarantees effective leakage.

Cutting the band in the corner, which is often done by some installators, is not an effective protection and eventually makes the whole isolation completely useless.
