Moideen,
I do not have a clue what you are using , but to get you pointed in the right direction, is this similar to what you are trying to describe?

You can either say yes, or describe what you are really using.

berkshire: manufacture details is unknown, i was told that the typical value shall be around .65w/m2/k.

If the mfg can't give you technical information on the panel, don't use the panel.

Given that you can't even describe the insulation material, I suggest you go to:

willard3: the manufacture didnt say anything, i have not direct contact with the client, their contractor said me to calculate the heat load,they dont have data of sandwichpanel, also this is not new ware house, old one and upgrading the ware house.
