The Opaque construction component not working

I am making custom construction for roof and wall. But the opaque construction component is not taking the values of plaster. It is only taking values of wall material that i have inserted in material. its not considering the entire asembly of plaster both side with wall material in between.
I tried deconstructing the material and construction set and I am getting same r value for both.
Please help with this.
