In certain areas, the following substances, as well as a number of others, are prohibited to act as flashings; uPVC, Zinc sheet, flexible flashing tape, and copper. The aforementioned materials are unable to be utilised in close synchrony with aluminium because of the effects that electrolysis brings on, which are able to corrode one of the mismatched substances when they’re exposed to moisture or water.

To achieve suitable flashing around aluminium doors and windows there are really only two alternatives for you to use; galvanised steel and aluminium itself. As you might expect though, the steel must be formed, forged, coated, and integrated first before it can be put to proper use.

The main issue with uPVC is that it doesn’t have the necessary credentials to endure the set time frame when introduced to harsh ultra violet rays. Eventually it breaks down, turning brittle. The divergent contraction and expansion of PVC flashings has been documented very well, with cracking being unavoidable.
