Here are six options to consider.
Aluminum frames have come a long way since the 1980s, namely because metal conducts heat and cold really well. Window manufacturers have put in a thermal break — rubber or some other material that breaks the conductivity — between the aluminum on the outside and on the inside; this largely negates the transfer of heat and cold.
There is also better soundproofing because of better glazing, which is the formal name for the double- or triple-paned glass unit within the frame. No one puts in a single pane of glass anymore.
