In order to upgrade internal thermal system for RC wall with less spatial loss, a new site-fabricable thermal system using quite thin vacuum insulation panel(VIP:5 mm and 8 mm) is developed here and compared with traditional XPS thermal system(45 mm) by Calibrated Hot box Method. In this new system, small pieces of plastic blocks in place of furring strips are arranged on lattice points of a square lattice on RC wall with VIPs in between them and with VIP joints covered by site spray foam. VIP system shown close score to Japanese Flat35 standards whereas XPS shown adequate score to it. For further upgrading of new system, improvement of joint heat bridge will be necessary.
