Wall installation of your dog or cat flap offers maximum flexibility in placement and ensures that the passage for your pet is harmoniously integrated into the architecture. But how does this work technically with regard to insulation values and solid wall thickness?
The technical solution for every wall thickness
A common concern with cat flap wall installation is the thickness of the exterior wall. Modern buildings with external thermal insulation often achieve considerable thicknesses. Thanks to our modular tunnel system, there are virtually no limits. The petWALK pet door covers wall thicknesses up to 70 cm. The appropriate tunnel system is added in our configurator depending on the individual wall thickness specified and can be precisely adapted to any individual situation – whether it's a 20 cm brick wall or a 60 cm passive house wall with thick insulation.
Thermal separation: No thermal bridge in the wall
A hole in the house wall must never become an energy leak. While a simple shaft in conventional flaps often leads to mold growth, condensation, and massive heat loss, the petWALK pet door has been consistently thought through to the end:
-
Insulated tunnel: The tunnel walls are installed airtight using sealing tapes and can additionally be insulated with mineral wool.
- 100% airtightness: petWALK pet doors meet the strict criteria for passive houses. This saves heating costs and, thanks to the thermal bridge-free construction, there is no condensation.
- The wall installation offers maximum stability, excellent insulation values, and an unobtrusive appearance. With the appropriate tunnel system from petWALK, a structural project becomes a lasting comfort solution.

Please note: Since each installation situation is individual, petWALK can only give general recommendations for model selection and installation.
Frequently Asked Questions
What is the maximum wall thickness allowed for an installation?
The petWALK pet door covers wall thicknesses up to 70cm. The appropriate tunnel system is added in our configurator based on the individual wall thickness specified and can be precisely adapted to any individual situation.
How is the tunnel thermally insulated?
When installing in a wall, the space between the tunnel and the masonry can be filled with insulation material. This ensures that the thermal envelope of the house remains closed and no thermal bridges are created. The intermediate space must under no circumstances be foamed, as the pet door must be fully accessible for maintenance and, if necessary, removable.
Is it possible to install a wall later?
With a professional breakthrough, wall installation can also be realized in existing properties.
Do I need special tools for assembling the tunnel extension?
No, the system is designed for easy assembly. The tunnel elements can be easily fixed to each other.
