What Round Lake Beach's climate means for your window spec
Lake County sees about 37.8 inches of precipitation and 43.4 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a Round Lake Beach window matter as much as the glass sitting in it.
So ask any Round Lake Beach contractor how they handle both, not just which brand they carry.
