I have a conservatory, and I have had to open the plasterboard walls to access the pipes and cables.
The plasterboard is foil backed, and there is a layer of mineral-wool type insulation (as used for lofts)placed between it and the breeze-blocks of the outside wall.I am considering adding a reflective foil bubble-layer (such as thermawrap) to improve the insulation.
My question is: where should the foil layer be placed?
Should it be btween the plasterboard and the mineral wool, or between the mineral wool and the breeze-block outside wall?
If I wanted to use the same product in a loft, in combination with mineral wool, where is the best place? ie immediately on top of the ceiling baords and underneath the mineral wool, or on top of the mineral wool?
I have been trying to think through the physics, and only succeeded in confusing myself.
Help!!
Thanks
