FAQ
|
Is this the same as the Thermo Panel 3e? This is very similar in that it has the same height ranges, flap sizes, and dual-pane Low-e glass. However, this vinyl panel is specifically made to fit better in the wider vinyl slider tracks. Read about the differences between vinyl and aluminum pet door panels here. |
|
Will it fit all vinyl sliding glass doors? This panel fits doors that have a recessed track at least 1-1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail |
|
Does it lock? We do include a c-clamp lock to lock the panel in place in your slider track. However, the panel does not mate with your existing sliding door lock. You can also use a Charley bar or wooden dowel for additional security. |
|
Can an intruder remove it from the outside? The thumbscrews are on the inside of the house so you cannot loosen them from the outside. |
|
Does the flap lock? The severe weather vinyl sliding door panel comes with a secure locking cover to block access to the flap when needed. |
|
Does this panel insulate well? Yes, it insulates very well. The flap is lined with magnets on three sides to stay shut in winds up to 50mph. The glass in the panel is dual-pane, Low-E for maximum insulation. |
|
How do I measure for it? You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track for your track height. |
|
Does it come in any color other than white? No, but the vinyl can be painted to match your home. |
|
What if my track is wider than 1-1/2"? It will still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly. |
|
Does your door have to be vinyl? No, this can work for aluminum sliders with tracks at least 1.5" thick. |
|
Is the flap flexible? It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps. |
|
Is the flap clear? It is a little foggy, but it is see-through so it's easy for pets to use. |
|
Will this form condensation like the aluminum panels? Nope! One of the benefits of a vinyl panel is that it won't "sweat" in cold weather the way aluminum panels can. |
