The days of installing windows and doors with visqueen are long gone. This is one of a best practice methods to installing windows in a water resistant & air infiltrating manner. 1. Bottom & top of windows, the Tyvek gets cut even with opening. Top gets cut upward at a 45° angle approximately 10", and tacked up out of the way. 2. Sides get cut 1/2 the thickness of the stud and Tyvek taped to stud. This prevents air infiltration. 3.Tyvek FlexWrap is installed on sill and 6" up stud. This prevents water from ever getting to wood sill frame 4. Window is installed into opening level, plumb & square. 5. Top of window gets Tyvek tape over nailing flange to sheathing. 6. Tyvek/Dupont Flashing is installed along the sides with a 1/2" onto window cladding. (See detail for cutting side folded over top & top flashing over sides). 7. Top piece of flashing is installed. 8. Tyvek is untracked & folded over flashing & Tyvek tape goes across top to secure it. 9. 45° angles get Tyvek taped. 10. We can't put flashing tape on bottom because it could trap water if it ever made its way through everything else, but what we can do is, in the last detail, is put a Tyvek "skirt" on the bottom which gets tapped to nailing flange (but NOT the bottom) which helps to further prevent air infiltration. Normally the skirt is at least 12" long below window, this install that was obviously not possible due to the foundation wall being so close. 11. Spray Foam inside around window to complete Install!!! One additional step can be used which is to add a pitched sill before sill flashing goes on. Generally I do that when near water as an added layer of protection. Let me know what you think or how you do it! #CDI #ConstructiveDesignInc #termitedamage #suffolk #instagramcontractors #contractorsofinsta #homeimprovement #renovation #exteriorrenovation #doinitright #windows #doors #windowinstallation #andersenwindows @andersen_windows @tyvekdesign #dupont #deerpark #deerparkproject https://www.instagram.com/p/B7GpmYhJ0RK/?igshid=1fdtlrt7o9582
