The transformers in the live action movies are depicted as being made entirely out of inorganic materials, of course, the coldness of space has no effect on the transformers due to there being no liquids whatsoever in the transformers’ bodies, plus the fact that space is a perfect vacuum, and being frozen in the Arctic Circle/ Hoover Dam only delayed Megatron; He was just in Stasis Lock before he thawed out, so they are not weak against extreme cold. The movie stated that they were weak against extreme heat, which is why the soldiers were armed with High Heat Sabot rounds when they were fighting in the fictional Mission City. The soldiers learned that when fighting Skorponok in a Qatari town. They said that the transformers’ weakness was extreme heat.
The vacuum of space makes an excellent insulator due to the inefficiency of radiating away heat.
I guess “Making Sense” wasn’t in the budget
