Sir, Van, totoo bang mas malamig ang loob ng bahay pag ganitong technology ang gagamitin (walls w/ styrofoam in between concrete)? Kasi ganito ang "sales pitch" nung taga Megaworld sa mga housing projects nila.
I opted to use ceramic tiles sa wall facing west... based on theory na conrete gives off heat, while ceramic absorbs heat (as seen from bakery)..then tinted the windows..
sa province yon na project, here di ko magawa, madami adjustments hence more costs
