Insulated plasterboard

[Red]

hi, in the process of ordering PIR insulated plasterboard,  used British Gypsum items recently and also Gtec,both seem identical visually, due to quantity required prices have varied but the Gtec ones seem to be the cheapest,  any thoughts on out of the two is the better product

Order a couple of each to get started and see which is the one with the plasterboard best bonded onto the PIR. I’ve had some where the two have separated and that’s bloody annoying. 
Storing these perfectly flat is paramount, and again some boards have arrived with a cup in them from being stored poorly, on a knackered pallet etc, and I’ve had to store them the other way around to retrain the board to be flat. 
Quality of the board is one thing, but discipline of the supplier is another key consideration.

We use both 

and also G tech metal 

Gypsum are better quality 

But do the same job

Thanks for the replies,  if anything the British Gypsum boards seem to have very slightly thicker vapour barrier but other than that are identical ,although the Gtec seem to be slightly harder on the board construction, when fixing the screws are easily pushed through the Gypsum board
