There's another thread about this just a few days ago and Simon Galley (Ilford) said that freezing or even refrigeration isn't really necessary with B&W films.
Yes it will extend the life, but most of us use it well before freezing would be beneficial, Colour pro films are different, they need refrigeration.
What sort of shelf life and extension beyond expiry can be expected from freezing over cool storage?

I am not concerned for deep-frozen film that expired xx number of years ago if it has been stored carefully.

Difficult to say, possible 10-15 years and longer, that doesn't mean there aren't slight changes in the emulsions though.

I agree with BradS in the other thread that sometimes people are overly cautious..
Maybe if your favourite emulsion is being discontinued there's a case of stock piling, if you have sufficient spare cash, but it's not for me.
I kept some Orwo Pan in the freezer, with an expiry date of 2005, and so far it's worked perfectly. I think I'll start to move the B&W stock from the freezer to the fridge, since around three quarters of my stock is colour, and I'm getting domestic complaints that there's no more room for food in the freezer. Besides, I've just had another delivery of Agfa APX, and that really is for stockpiling.

I don't want to open new topic, because there are similar already, so:
I have around 8 rolls Portra 160vc and 3 rolls T-max 400, all expired 2005-2006. I think that I will use them all through the summer, maybe most of the colors film in the end of August.
I store them in a closet, in a guest room on 2nd floor on the house (so no-one lives there), the room is dry and it's pretty dark for the most part of the day.
I'm little afraid that on the 2nd floor the temperature are higher than on the ground-rooms which have more condensation on the walls, a thing that might affect the films maybe more negatively than the temperature?
Is this safe place?
Or should I freeze them.

Not really for the colour films.

If your films are still in the sealed wrappers etc then downstairs should be OK, they are protected against humidity.

I leave the digital work for the urologists and proctologists.
I believe that for long term storage Kodak suggests keeping all films at -5 C to -10 C. They say that this temperature represents the best compromise between quality and electricity cost.
Other factors also determine how well a fim ages such as background radiation and cosmic rays. Both of these are however out of our control.

Keep it Cold so it don't get Old. Store in zip locks in smaller quantities so you don't have the bring a large amount back to room temperature.
