ᐅ Cat flap in KfW55 house with ventilation – any experiences?

Created on: 23 Mar 2021 09:33

We have a KfW-55 end-terrace house with insulation, triple glazing, and a ventilation system. Now we want to install a cat flap in a glass panel next to the patio door. Has anyone done this before?

- How does this affect the performance of the ventilation system? It won’t be completely airtight anymore.
- How much heat loss can we expect – it’s just a simple plastic flap, after all.
- Is installation even possible with triple glazing that also has RC2 security features?

We would have a professional company do the installation, but we’re not sure if it’s all feasible. I would appreciate hearing about others’ experiences.

So, we had the cat flap installed back in June. This is what it looks like. The tomcat has taken to the flap well and especially uses it when no one is home to open the door. Naturally, he brings his mice inside. You just have to deal with that. But whether dead or alive, they are immediately thrown back outside. The eating happens outdoors ;-)
