  • Great panel review by Mikey
    5 5 Great panel

    I live in California so the door works perfect. The crazy weather that the East Coast gets, I would recommend the enduraflap, but this Petsafe works fine for me here. The panel quality is amazing and very well built. I highly recommend this for everyone living in mild climates . My cat is happy they can go to the catio freely now.

  • great door review by kelly
    5 4 great door

    I really liked this door, however the dog flap is not my favorite. I had the Endura flap and I went to the this door as it was cheaper. Big mistake!! The door does not stay shut in winds or storms. It does not insulate. It is amazing in mild weather though which is why im rating it 4 stars. I do not recommend for extreme weather but if you have mild weather its great.

  • Great panel, not so great flap. review by Athena
    5 4 Great panel, not so great flap.

    I love the quality of this panel, but the flap is not amazing. It tends to flap in the wind during the storms and its not as durable. I have had to replace it 3 times in 3 years. I shouldve went with the Endura flap as the reviews on it are 100x better.

Installing the Thermo Sash 2



Installation Instructions for the Endura Flap Thermo Sash Pet Door

1. Open your window

2. Place the Endura Flap Thermo Sash Pet Door into the track of your sash window

3. Release the spring mechanism by loosening the thumb screw

4. Tighten the thumbscrews once the pet door has expanded the full width of the window

5. Once you see the fit is correct add the foam weather stripping in the top and bottom channel of the pet door

6. Next install the draft stopper.  Clean the top edge of your sliding window with alcohol so that you are sure to get all the debris off.  

7. Remove the blue cover over the adhesive and install the draft stopper so that the edge without the adhesive is just barely touching the glass on the stationary or upper window.

Adjusting the Pet Door for your Window

Due to the fact that there are many types of windows, you may need to modify your installation using shims or similar materials. If there is a gap, you can use the shims to even out the pet door. The included weatherstripping will help further.

Removing Your Thermo Sash Pet Door

You will first need to loosen the thumbscrews, you may first need to lift the pet door up to loosen the bottom screw. Then compress the window pet door and tighten the thumbscrews once again for easy removal.

First raise up your window and check that it can go up far enough to be left with an opening 15" high. Next measure the width of the track from left to right, including going inside the track on both sides. Last measure how wide the track is that the window slides in (needs to be at least 1")

Track width needs to be at least 1" thick.

It comes standard on the left, if you are looking from the inside of the house. You can switch it by taking out the pet door (needs a screwdriver) and flipping it upside-down.

This is designed to be a fairly simple install that does not require any tools. Take a look at the video under the installation tab to see if it something you would be able to do.

The Thermo Sash 2 has flexible flap with a magnet on the bottom to help hold is shut. The glass is single pane for moderate insulation value,. That said this is recommended for more moderate climates or if you a simply on a fixed budget.

You can by removing the flap, although you would have a big open hole.

If you've mismeasured, you may be able to fix it. To make your sash cat door about 3/4" wider, you may purchase a width extension (or make your own using 1" x lumber). To make your window kitty door insert slightly shorter you may trim the side flanges on the spring loaded adjustment piece with a hacksaw or a jigsaw with a metal cutting blade.

Any of the Thermo Sash doors that are custom mean it is non-returnable.

We can only do custom widths, not custom heights.
