Climate and energy performance in South Riding
Loudoun County sees about 43.2 inches of precipitation and 21.0 inches of snow in a normal year.
Weather at that level is one more reason the flashing and sill pan under a South Riding window matter as much as the glass sitting in it.
So ask any South Riding contractor how they handle both, not just which brand they carry.
