Aluminium Patio Doors
I have 2 Aluminium sliding patio doors in the house installed around
1975, by the previous owners. During the recent cold spell, I have
notices the cold temperature of the aluminium frame compared to the
temperature of the UPVC frame in the rest of the house. Is there a wat
to reduce the heat loss via the aluminium frame or Do I need to
consider replcement with UPVC.
