Will it fit a standard patio door?

The 72 by 80 inch size is built for a wide sliding or French door. Measure your opening's width and height first, since the curtain needs to overlap the frame for the hook tape to hold.

Does it really keep heat in?

The fiberfill and PU-coated backing slow airflow and radiant loss better than an open doorway or a thin mesh screen. It is a barrier, not a sealed door, so expect a reduction in drafts rather than a full stop.

Can I install it without drilling?

Yes. The kit includes hook tape rolls and pushpins, so the tape can be stuck to the frame or tacked in place. Clean and dry the surface before applying tape for a firm hold.

Will my dog be able to push through?

The magnets are designed to part with a push and snap back afterward. Small pets and children can usually pass; very large or determined dogs may pull the curtain off its tape.

Wipe the oxford face and PVC window with a damp cloth and mild soap. Avoid machine washing, which can clump the fiberfill and damage the magnet pockets.

Does the window cut down on insulation?

The PVC panel is a thin clear layer, so that strip insulates less than the filled fabric around it. It is a trade-off for daylight rather than a full thermal pane.
