Create a Customizable Pet Door with a Transforming Sash Window

A window pet door can be a great alternative to installing a pet door in an exterior door. One benefit of building a window pet door is that there will be no evidence in your house door that you have a pet. Before designing your door, measure your pet so that you know how big the door should be. Check the window into which you want to install the pet door to ensure that there is enough room in the bottom pane and to make sure it is sturdy enough. For added safety, reinforce the window with a stronger material like wood or metal.

Once you have the window prepared, you will want to start building the door for your pet. Cut out a board that is the exact size and thickness of the glass window, and then use a jigsaw to cut out the outline of the door shape. Before you move any further, make sure your pet can traverse through it safely. This test can also help introduce your pet to the door at a young age, making it easier to train them to use it after it is complete.

The easiest way to make a pet door that can move freely in both directions is to use a strip of strong polythene. Stretch the strip to feel it’s grain, then mark the strip that will be used for the door hinge. Then, use the strip, secured with adhesive and nuts and bolts, to attach a frame to the board on an outside-facing side so that it does not interfere with the window moving. After installing the frame, attach the door flap with whatever connectors are suitable – staples for thin plywood doors for example. Make sure that the flap is free to move through the whole arc so that larger pets can also easily use it.

To finish off the pet door, grind the nuts and bolts to the level of the board, seal, and paint. Make sure to also install brush strips around the outside of the door to minimize drafts.

Now, remove the glass window pane and clean out the normal grit and putty from the frame of the window. Put a bead of silicone sealer around where the board will be fitted, and then secure the board with fine wire nails. Seal the board with window putty, and then let it dry before introducing your pet to the new door.

Finally, train your pet to go through the door and make sure there is safe access indoors and out for them. With these steps, you will now have a secure and attractive pet door to last for years to come.
A window pet door can be a great alternative to installing a pet door in an exterior door. One of the benefits of a window pet door is that there is less evidence that you have a pet in your house. Installing a window pet door isn’t difficult, but there are certain steps you need to take to ensure that your pet door is properly installed and secure.

First of all, you’ll need to measure your pet to make sure that the opening in the pet door is big enough to accommodate it. Secondly, you’ll need to check the window into which you want to install the pet door. Ensure that there is enough room in the bottom pane and that the window is structurally sound enough to withstand repeated pet use.

To make a sash window pet door, you’ll need to cut out a board of the same size and thickness as the window glass. Use a jig saw to cut out the shape of the pet door. To make sure your pet can pass through the hole, test it at this stage. This way, you can ensure that the hole is big enough and also introduce your pet to the door.

For the hinge motion, use a strip of heavy duty polythene. Because it only tears in one direction, make sure that the grain is vertical to the door. To make the frame for the pet door, build it with strips of wood and attach it to the board with adhesive and small nuts and bolts fitted with large washers.

The door flap can be made of thin plywood or flexible material and attached to the polythene hinge. Make sure that the flap is free to move back and forth through the maximum arc. After grinding down the nuts, seal and paint the woodwork with a finish that matches the sash window.

Finally, to fit the window pet door in place, remove the glass window pane and clean out old putty and grit. Place a bead of silicone sealer around where the board will be fitted for better adhesion and waterproofing. Place the board in the frame, press it into place, and secure it with wire nails. Then, apply window putty around the edge of the board.

Now, all is left is to introduce your pet to the new pet door and make it aware of how to use it safely. With your pet door properly installed, your pet will now have an easy way to enter and exit your home.
