The question is a fairly obvious one but allow me to address the main concern i was hoping to be in a detailed answer. What are the implications (if any) of what may happen to the dew point within an insulated wall that has foil backed drywall. Foil backed foam board for exterior sheething is sold, but you won't find foil backed drywall anywhere. It begs to ask the question: why? Would installing such a product create condensation on the back side in the wall, causing the water to fall to the sill plate. i'm looking to increase my energy efficiency in a new home construction, and am open to unconventional ideas. Maybe someone out there has encountered this before.

RE:
would aluminum foil backed drywall (gypsum board) reflect or retain heat or cool back into my house?

It would store the heat in the wall along with insulation,insulation was designed to hold heat and dissipate it as the outside temperature cooled at a gradual rate, gypsum board is a ceramic based product if it were outside being white it would reflect the heat from the sun but if heated up with a convection source it would heat up.

The foil inhibits radiant energy transfer in both directions. Only heat transfers and cool is an absence of heat.

It would reflect heat back into the house.

google it or go to a local home center and ask in the building department. it's unlikely that you will find what you are looking for here...
