Timber size for 3m span suspended ceiling

Hi all, my partner is starting a dog grooming business from home in our conservatory.

I need to install something quick and easy to help with the heat incase the dogs cook.

My initial idea is to put in a suspended ceiling by using 4x2 spanning the 3m width and then either put insulation boards on the top side and clad the ceiling side with pvc tongue and groove. Length of the conservatory is 4m so I was planning on putting 4x2 every 400mm.

Obviously this is a bit of a bodge for now until we can afford to re-roof properly, but would 4x2 suffice in this situation?

Thanks all
