Best Insulated, Weatherproof & Energy Efficient Dog Doors: Buyer’s Guide
What Makes A Dog Door Insulated, Weatherproof & Energy Efficient?
It’s usually a few key things:
- Double or triple flaps – in case one flap doesn’t seal closed all the way, and to create a weather catching air pocket in between the flaps
- Made of an energy efficient material – the frame and flaps can be made of energy efficient insulated materials like structural molded plastic and energy efficient vinyl for example
- Brush seals – brush seals inside the frame help insulate the door and seal it
- Magnetic flap closure – to help the flaps seal
- Weatherproofing strips – like the brush seals, weatherproofing strips help insulate and seal the door
How To Measure For A Pet Door?
The manufacturer should give you instructions on how to measure your dog. But generally, you might:
- Measure the width of the rib cage
- Measure from the floor to the top of your pet’s shoulders
Consider the width of the flap opening, and what height the top of the flap opening is above floor level, and compare those measurements to your dog’s measurements to select the right size pet door.
How Do You Install A Pet Door?
There’s no substitute for following the manufacturer’s instructions for installing their Pet Door product which should come with the door, or should be found on their website. They may also have YouTube videos to help you.
Generally, for most Pet Doors you need to cut out a section of the door or wall, insert and fix a frame or tunnel extender into the wall or door, and then fix the door onto the frame.
This may involve using a jigsaw or cutting tool, a drill, a screwdriver (can be phillips head or sometimes a non standard screw is included in the kit so check this), and the hardware included in the pet door kit.
A cutout template should come with the door, along with the frame, hardware, other sundries and the pet door itself.
Some people choose to install themselves, whilst some people choose to get a professional handyperson to do it for them.
Some people also choose to go to the hardware store and purchase extras like additional weatherstripping, stronger screws/bolts and caulking sealants to further weatherproof and secure their door.
Accessories For Pet Doors
Common accessories people might buy are a wall kit if installing in a wall, or like mentioned above, small items to seal and secure the door in the door or wall.
