Product Details


The positioning of the drainage holes means that if the foundation is plastered it will not interfere with the air movement & draining of the cavity.

Base & Cavity Closure Flashing allows for venting & draining the cavity as well as providing a straight rigid base for the solid plaster to finish to.

External Corner Joiners Quickflash Code 15 (fits Code 01)  & Quickflash Code 16 (fits Code 10) are recommended, strengthen corners, save time & leave straight clean lines.

We also provide End Caps for where the flashing butts into a doorway or just terminates. These are Code 44 (fits Code 01) and Code 45 (fits Code 10).
