Great idea with the yoga mat flap! I’m building a window insert for my new puppy and I think that’s the perfect solution. I’ll probably add some neodymium magnets to the bottom so it latches in place. Thanks for the good idea👍
I like the notched board for the tracks and see-through panels. The yoga matte doesn't seem like it will last long or be very energy efficient. Looks like you should add some thick weather stripping on the edge of panel that touches the door. Door looks way wider and taller than it needs to be for the dog. By making the side rails and door width all narrower you it might end up just enough to lock the sliding door with a board in the inside house side of rail to keep intruders out. It will also be more energy efficient. Would have been nice to see it being put in and taken out. I got the impression that it lifts in an out fairly easily?
Thanks for the input. Weather stripping would be a good addition. Surprisingly the yoga mat is still in good shape. The dog did grow into the size of the door; it is about perfect now. The door lifts in and out very easily so the system is not lockable without some modification. I think a youth could probably squeeze in the door sideways anyway.
