What is the difference between the Celotex PL4000 boards and the GA4000?
PL4000 is a 2-in-1 product with the insulation board laminated to a sheet of 12.5mm tapered edge plasterboard. The GA4000 range is an insulation board with only a foil facing to both sides. 
What thickness insulation is on the PL4050 board?
The Celotex PL4050 total thickness is 62.5mm. This consists of a 50mm insulation board bonded to a 12.5mm plasterboard. 
How thick a PL4000 Celotex board should I use on my external wall? It can get very cold in winter.
The Celotex PL4000 is a very good insulated thermal laminate. When deciding on the thickness to use, the desired result has to be considered. While the thicker the board the better performance can be expected, this needs to be balanced with the space this will take within the room and around openings such as windows/doors.
