We’ve  already  talked about the eight reasons why stucco and stone fail and  we’ve already mention that the main reason why stucco, siding and stone installations fail is because a wrong window installation. We recently had the opportunity to do an stone front  located at NY, when we arrived to the site job, the first thing we did was to check the  installation of the windows, we normally do this because  we know  that no matter how good our waterproofing system is,  no matter if in this case the builder  of this particular building is using  the Zip system as their sheathing system of choice, we still need to make sure that the windows are properly installed,  this will guaranty  that the entire system will work as it should from inside  to outside.

Wrong window installation is  the main reason why stucco, stone and siding fail.

Never underestimate the  sneaky damage power of water and moisture in a wooden structure, in this particular case we choose to go with what is called a partial adhered new  construction window installation. We hope that this video series will give you a better understanding  on how  to install a window, the materials we use and why.

For the full video series visit our  How to perform a window installation  play list, we hope the videos are helpful to you.

List of materials  you will need to perform this task.

1. If you would like to add an extra layer of water protection to the system I will suggest you to go with  Fortifiber’s Super Jumbo Tex as your second layer of water protection.
2. DuPont Tyvek home wrap  as your first layer of water protection.
3. DuPont Tyvek sheathing tape to  seal all the joints between the paper.
4. DuPont 9″ FlexWrap to create a sill pan for the window, this tape is very important since is the one that  will seal the lower corners and protects the  window sill. We  have chosen the 9″ because of the protection, the bigger the tape the better  at wrapping both the  window sill (framing) and the paper.
5. DuPont 4″ flashing tape to install over the  window flanges. ( remember, this tape goes on the left, right  and top)
6. Drip cap flashing (Z flashing) this will be installed over the window head  casing.
7. OSI  Quad max Sealant  to seal the joint between the window flange and the structure
8. OSI Quad foam window and door foam sealant to  air and water  seal the joint between  the window side jamb (framing) and  the window.
9. 1/8″ horse shoe shims  to create a gap/space between the  window and the window sill (framing).
10. 3/8″ staples to fasten the water resistant barrier ( paper) to the wood sheathing.
11. 2″ Electro-galvanized  roofing nail to  nail the windows in place.

 

List of tools  you will need to perform this task.

1. Stapler  ( hammer tacker) to install the water resistant barrier  ( building paper).
2. Utility knife to cut the paper, the sheathing tape and the self adhesive membrane.
3. Hammer to clean the  window rough opening if necessary and to nail the window in place.
4. Metal lath straight cut aluminum snips to cut the drip cap flashing.
5. Level  to assure that the window is been installed plum and level.
6. Rubber roller to  make sure that the self adhesive tape will stick to either the substrate,window flange and paper, see if you can find a 4″.

We always are looking to improve , pls let us know if you have any questions or suggestions.

Good luck with your project!!
