About
Enhance the comfort of your home in both summer and winter
Traditional window frames are hollow, a major weakness that causes heat loss through conduction and convection.
To address this issue, Président’s engineers developed the Iso-Therma process: injecting urethane foam directly into the chambers of the PVC frame to significantly increase its thermal resistance.
Combined with high-performance sealed units, this proprietary process significantly improves the energy efficiency of each window: less condensation, less heat loss, less noise, and unmatched indoor comfort.
