My insulated dog flap favorites

product test

PetSafe Extreme Weather Plastic Pet Door

The PetSafe plastic pet door is extremely energy efficient. The dog flap consists of three individual flaps that insulate your house well even at very low temperatures. However, the effect of the flap should not be underestimated even at very high temperatures, because the flap also prevents the inside temperature from adapting to the outside temperature.

The magnetic seal also keeps heat and cold out and ensures that the flaps always close quickly and tightly. Drafts don’t stand a chance either.

If you want to close the dog flap completely, for example because your dog is not allowed outside at night or you are not at home, you can use the retractable locking plate. So no other animals or burglars can get into the house.

The color of the plastic frame can be matched to the existing door. You can simply delete it for that.

The door fits into wooden, metal or plastic doors that are 3.75 to 5 cm thick.

pros

  • With three flaps, this insulated dog flap fulfills its function optimally.
  • The magnetic seal prevents drafts.
  • If necessary, you can close the flap completely.
  • The product can be built into wooden, metal and plastic doors.
cons

  • The flap is relatively heavy, making it difficult for small, weak, or injured dogs to operate.

Ferplast 72108011 Dog Flap

The next dog flap with insulation tested is that of the Ferplast company. It is made of robust plastic and can be installed in doors made of wood, glass or metal as well as in walls.

Thanks to the four-way locking system, you can individually determine where your dog is allowed to go and where not. You can adjust the flap so that your four-legged friend can only go inside or outside.

Of course, you can also let the flap open in both directions or close it completely. I find the direction indicator very practical, which shows the direction in which your darling went last.

The integrated wind stopper system prevents drafts from entering the house.

If you are looking for more chipped dog flaps, I recommend my guide to chipped dog flaps.

pros

  • The dog flap is suitable for plastic, metal and wooden doors and can also be installed in masonry.
  • There is a four-way locking system.
  • The direction indicator shows in which direction your dog was last heading.
  • The wind stopper reliably prevents drafts.
cons

  • The flap closes relatively loudly.

Trixie Pet Products 2-Way Locking Dog Door

The Trixie insulated dog flap consists of a sturdy plastic frame and a transparent door flap.

The PVC flap is very strong and durable, yet flexible so your dog can easily slide it open. To ensure that the flap does not flap even in strong winds, it is equipped with a metal bar at the bottom for weighting.

Drafts don’t stand a chance and your home stays pleasantly warm even in extremely cold temperatures. If you’re not there, you can slide in a metal wall that protects your house from burglars. Even in extremely bad weather, this is a good option.

The included tunnel element extends the depth of the door from 1.9 to 3.2 cm.

If you are looking for other dog flaps for large dogs, I recommend my guide to dog flaps XXL.

pros

  • The dog flap consists of a robust plastic frame.
  • The moveable PVC leaf allows your dog to go inside or outside whenever he wants.
  • A retractable metal plate keeps bad weather and unwanted intruders out.
  • The metal rod weighs down the flap and keeps drafts out.
cons

  • The metal plate to slide in is difficult.
  • The installation template is inaccurate.

Dog Mate dog door

Dog Mate’s flap has robust safety discs. So drafts don’t stand a chance. In addition, there is a weatherproof brush seal and a magnetic closure, which contribute to good insulation.

If you are not there, you can simply close the flap so that no other animals or people can get into your house.

The dog flap has a self-covering for installation depths of up to 50 mm.

Installation is quick and easy and can also be easily managed by laypersons with a little manual skill.

pros

  • The flap effectively protects against drafts.
  • The safety panes are very robust.
  • If necessary, you can completely close and lock the dog flap.
  • Installation is quick.
cons

  • The flap closes relatively loudly.

Sailnovo dog flap

Finally, I would like to introduce you to my personal award winner. The Sailnovo dog flap convinced me with its low price and good quality.

The four-way closure gives you every opportunity to control your dog. Either you open the flap only inwards, only outwards, in both directions or not at all.

The damper can be built into brick walls, PVC doors, wooden doors and metal. The wall thickness should be 2 to 5 cm.

The manufacturer advertises that the door works very quietly. The special seal and a magnetic closure prevent drafts.

pros

  • The dog flap convinces with an unbeatable price.
  • There is a four-way closure.
  • The flap is suitable for metal, PVC and wooden doors and can also be installed in brick walls.
  • The door makes hardly any noise.
cons

  • Locking is difficult at first.
  • Some customers had problems with trimming the plastic frame.

Purchase advice – Dog flap insulated

You should pay attention to these criteria when buying an insulated dog flap

When buying a dog flap, insulation is particularly important to me. Depending on the model, this may have been implemented by several flaps one behind the other, a brush seal, magnetic closures or similar.

It is important that no draft comes through and that the flap helps you to live energy-efficiently. The flap should also move smoothly and not make any loud noises. I always find it practical if you can completely close the passage.

Four-way systems also make sense in some cases. Ultimately, the installation must also be possible without any problems and quickly.

Conclusion

My favorite was the PetSafe Extreme Weather Plastic Pet Door. The three flaps achieve optimal insulation so that drafts don’t stand a chance.

The magnetic closure also contributes to energy efficiency.

The flap can be installed in doors made of different materials and is therefore very versatile.

If necessary, you can also completely close the passage and thus seal off your house from intruders.
