Insulation

Plastic foam provides insulation during hot times as well; those of us
who suffer through sunny, warn winter ,days while the rest of you are
shivering, properly for the season, by the fireside, drinking Irish
coffee, welcome foam, for it keeps soil in containers at ambient
temperatures, rather than allowing it to be warmed by direct sunshine,
as happens with other kinds of pots.
