As for fire safety, aluminum is able to resist the fire. Plastic will not burn, it will begin to melt and highlight the caustic smell. The task of any windows is heat and sound insulation. I must say that in this matter, aluminum windows are inferior to plastic windows. Their level of heat and sound insulation is much lower. But this does not apply to "warm" aluminum windows. “Warm” aluminum windows differ from the usual ones in that additional double -glazed windows are installed in them. In such cases, both plastic and aluminum windows will have the same level of heat and sound insulation. But the cost of such aluminum windows is very high. If the price of the issue is not critical, then you can choose “warm” aluminum windows that will last you for a very long time. If the price is high enough, then choose plastic. Please note that ordinary aluminum windows are perfect for balconies and loggias.
