INSTALLATION GUIDE

From Box to Barrier in Ten Minutes

Our hook-and-loop mounting system requires zero tools or hardware that damages your door frame. Simply attach the fastening strips around your doorway, press the curtain into place, and you're done.

The weighted bottom hem keeps the curtain taut and sealed while the self-aligning magnetic closure guides you through every time. Adjust the detachable windows to your preferred height for optimal visibility.

How It Works

1

Attach Mounting Strips

Peel and stick the included hook-and-loop strips around your door frame perimeter.

2

Hang the Curtain

Press the curtain edges firmly onto the mounted strips for a secure hold.

3

Position Windows

Attach the clear vinyl windows at your desired height or remove completely for summer use.

Frequently Asked Questions

What door sizes does this curtain fit?

This thermal door curtain is available in two size options: one fits doors up to 34 x 80 inch, and another fits doors up to 36 x 82 inch. Both sizes provide full coverage for standard residential doorways.

How does the magnetic closure work?

Multiple magnets are sewn into the center seam of the curtain, creating an automatic seal when the two sides meet. The magnets align and close immediately after you walk through, requiring no effort on your part.

Can I remove the windows?

Yes, the clear vinyl windows are completely detachable using hook-and-loop fasteners. Remove them in warmer months for airflow while still maintaining the magnetic entry system, then reattach when you need full insulation again.

Will this work with pets?

The magnetic closure is light enough for most pets to push through easily, and the durable Oxford fabric exterior resists scratches and tears from claws. The curtain automatically reseals after your pet passes through.

How much can this reduce energy costs?

By creating a thermal barrier between climate-controlled and unconditioned spaces, this curtain heated or cooled air from escaping through frequently used doorways. Users report noticeable reductions in HVAC runtime, with the curtain typically paying for itself within a single season.

Love it! Works great!

It was super easy to use/install. I’m using it on my trailer door since they don’t make dog doors for trailers. I was hoping to install it upside-down (I wanted the windows on the floor for my dogs to see out) but it comes with the Velcro already on the fabric so I installed it right-side up (although with a little work I could have flipped it). I can barely feel any cold coming through (it’s still winter) and it does a really good job keeping the heat in while allowing my puppies to go in and out of the trailer when they need to. One of my best purchases for the trailer.

Does it's job

Item pretty much exactly as described only complaint which is usually always the case with these sort of things is the hardware or whatever you want to call it that comes to hang the door though it works I feel as though the fasteners could be a little more heavy duty

The Best Buy I’ve experienced!

I use this as a dog door and it’s amazing! It’s insulated and during the summer/winter is 100% the way to go! I’ve bought two now to make sure I have a back up if my current one ever gets messed up!

So far, so good.

I’ve purchased several of these magnetic insulation curtains and they’ve all only lasted a year at most. This one so far has a lot of the same issues I’ve had with others in the past but one big difference is the thickness of the material. It feels much more durable which gives me hope it’ll last much longer this time.

Work great!

These are great!! We opted for this instead of a doggy door and it works great unless the winds are 25 mph+. The magnets do fall out of the fabric but I tried some silicone adhesive and it has been working.

Amazing product

We absolutely love this it does keeps the heat out and cold air in during summer so far so far the adhesive for the Velcro is holding up in the heat very easy to install it’s looks nice I would recommend 100% if you need something to cover the door I have two dog and no doggie door so we put this up so we can keep the door open some so my girls can go out when ever they want without warming my house up

Needs better fasteners

This is awesome but the tacks to put it up are way to small and does not hold it in place when you walk through they pop out and on to the ground.

Great product

This curtin is made of verry good material, we use it at the entrance door on our food truck. It keeps the cold out in the winter and the heat out in summer. Highly recommend.

Great Product for space with no doors.

The design is okay, depending on your use, it works well for privacy. I used in basement for privacy of outside looking in. I love the quilted design and the window view to allow you to see and have window covers for privacy. It can be used for many uses. I great for keeping cold air out during the winter months. I have slight disapproval for length of use, I used for 3 years. I do recommend it. NOTE: It's important to measure the the space it's used for especially the width of the doorway.
