Hi All, it has been a while since posting so, here is my current scenario: Remote cottage in Manitoba, Canada. New build last summer, typar went on last October, and we are just getting to the siding now. We are using Hardie lap & trim.
Should we, can we, do a second layer of Typar as it has been up & exposed now for a year? We get driving wind/rain on the lake side and thought a double layer might help anyway.
Or should we cut off the Typar & reapply? The building is insulated entirely with Soya foam – so it is pretty airtight (if that matters). A friend thought that maybe with 2 layers of Typar, the building would have trouble breathing?
Thanks for the advice!
