How to Install It Properly

In order to a proper job, you will need a number of tools such as Plexiglas, Styrofoam, or any other material that will keep the cold air in and the hot air out. In addition to this, you will also need a latch, bungee cord, or anything else that will keep the casing window open. As well as, self-adhesive will ensure that the unit is weatherproof.

Step 1: Measure and Check

Make sure that you are covering all details such as cutting and drilling before you get the Pixelglas. This is why, you should place the AC as close as possible to the installation site, so that the venting hose doesn’t need to be extended.

  • You should measure the window to determine how large the insert is
  • Check that the Plexiglas is the same measurement as the vent hose
  • If not, cut a hole that’s the same size as your air conditioner’s vent hose
  • Make sure that it’s the same size otherwise you cannot fit it correctly
Step 2: Install The Insert
  • Open the crack window and hold it in place with a latch. This will help prevent possible damage to the open window
  • Make sure that the window is reasonably secured and won’t get damaged if there is a breeze or light wind
  • Secure the insert to the window frame. You can twist clamps to secure the insert if you feel like you need to do it.
Step 3: Weatherproof the Insert

You have to remember that the insert is the only thing that divides the home from the outdoors. This is why it’s very important that you seal it properly so it’s waterproof. You must caulk where the window frame and casting meets. If you’re using self-adhesive, you should:

  • Attach it to the insert before you secure the insert to the window frame
  • The weather stripping should fit tightly between the window frame and the insert so it forms an effective seal
  • The weather stripping should have enough pressure on it so that it compresses
  • Make sure that it’s about half of its normal thickness where the window frame and insert meet

To make sure the window is as waterproof as possible, you can fit the weatherproof stripping between the wall and insert and also run it over the area where they meet.
