Do Builders generally follow building materials Manufacturers installation guidelines ?
As a home owner dragged into building science we have had to repeatedly discuss our building envelope failures with the manufacturers of products used in our build. With their engineers, with their support, and I get that the science and code of home building has changed in many ways in recent decades.
Again, I know nothing about building houses, it's our first and last build. Why when we look at a product like the DMX foundation wrap that is designed and certified to do its job if it is installed following the manufacturers guidelines. Why would it be installed any other way? The result is the homeowner has no warranty from the manufacturer.
Can someone in the building industry please explain for ourselves and other homeowners on the forum?
