Depends on a lot of factors... what kind of laminate... what are the min and max temps it will see... would direct sunlight hit the laminate making the temps far higher.

One problem with unheated spaces is that the humidity gets very high, particularly in winter. High humidity swells the backing and the floor buckles. That's why many companies do not recommend laminate in kitchens.

Yes... I forgot to add the Humidity factor to that... also VERY important.
