Yeah I didn't bother getting into the size of the gaps since I figured for a VN like this available assets were limited in what to chose from so at least having an abstract version of the cage was good enough since to block 4G [12.5cm] spectrum you'd need a mesh gap of around 4cm or less and to block 5G you'd need 0.3mm or less sized holes because 5g is millimetre wavelength.Exactly. Otherwise nobody would ever get any reception IN A CAR. Except of course we do. Oh, and while the cage doesn't strictly have to be one contiguous surface of metal to be effective, the size of the "holes" does matter - why do you think your microwave door is full of ITTY-BITTY holes instead of, oh, some 10x10cm ones...?
If my memory is correct anyway.
Id it were me I'd probably have just lined the entire room using rolls of self-adhesive foil, then you could just paint or wall-paper over it as you desire.
But it does need to cover the windows and ceiling.
I can't recall if they are on the ground floor or not, but if its a first floor apartment it might need the floor covered too.
