Conflict between Solitex Mento and Loewen Window installation instructions
We’re using Solitex Mento 1000 as a WRB along with metal-clad Loewen windows with an integral flange. Installation instructions for Mento published on 475’s web site are similar to the manufacturer’s instructions with one major difference. Mento recommends that the WRB at the jambs be folded back into the jambs and the window installed over the WRB (after installation of a pan). Loewen instructions call for cutting back the WRB at the sides of the open several inches so that the window can be fastened directly to the sheathing. My gut sense is that it’s crazy to cut back the WRB and rely only on sealant behind the flange and tape, but I’m hesitant to go against the manufacturer’s instructions in case it would void the warranty. What think thee?
