WCA stands for Wide Cavity Applications and the versatile Type WCA provides the solution for cavity widths from 150mm up to 330mm.
The WCA acts as a DPC, an insulator, and physically closes the cavity between inner and outer skins.
As cavities grow wider, rotational predisposition can increase and the sides of the Type WCA closer are friction fitted to accept some initial movement prior to plastering.
