Where’s the insulation?
I’ve just installed the cat flap.
I already had the Hub because I bought the “smart bowl”, which I have to say I was really happy with.
However, this system was installed in a newly built house with an A+++ energy rating, and it was very disappointing to discover that there’s no insulation at all. I installed several extension pieces, since my wall is 30cm thick plus the insulation layer.
Air gets into the tunnel and comes through the flap.
Terrible.
