ABSTRACT The present study reports on the reuse of the end‐of‐life fluorescent tube‐light (SFT) glasses for glass foam development. The sintering behavior of the waste glass has been analyzed using the hot stage microscopy (HSM). Subsequently, the foaming temperature is optimized to 750°C for glass foam preparation with controlled pore size distribution, leading to a thermal conductivity of 0.0772 W/mK. The presence of open and closed pore structures is quantitatively analyzed through FE‐SEM analysis. Further, the influence of foaming temperature and foaming agent concentration on regulating the pore size (4.59 mm–236 µm) has been examined to elucidate the governing factor in regulating the properties of the foam glass sample. The compressive strength of the developed glass foam material can be tuned in the range of 2.58–10.51 MPa for different construction applications depending upon the foaming agent concentrations.
