During window installation, what is the most critical factor for preventing water infiltration in Florida's climate?

Correct Answer

B) Proper flashing and weatherproofing sequence

Proper flashing installation following the correct sequence (bottom, sides, then top) is critical for preventing water infiltration. This creates a weather-resistant barrier around the window opening.

Answer Options
A
Using expanding foam around the frame
B
Proper flashing and weatherproofing sequence
C
Installing larger windows
D
Using double-pane glass

Why This Is the Correct Answer

Proper flashing and weatherproofing sequence is the most critical factor because it creates a continuous water-resistant barrier that directs water away from the window opening. In Florida's climate with heavy rains, hurricanes, and high humidity, the correct installation sequence (bottom, sides, then top) ensures water cannot penetrate behind the window assembly. This systematic approach prevents water infiltration that could cause structural damage, mold growth, and interior damage.

Why the Other Options Are Wrong

Option A: Using expanding foam around the frame

While expanding foam provides insulation and some sealing, it's not the primary water barrier and can actually trap moisture if not properly sealed with flashing and weatherproofing materials.

Option C: Installing larger windows

Window size has no bearing on water infiltration prevention - larger windows may actually create more potential leak points if not properly flashed and sealed.

Option D: Using double-pane glass

Double-pane glass provides energy efficiency and condensation control but does not prevent water infiltration around the window frame and opening.

Memory Technique

Remember 'BST' - Bottom, Sides, Top flashing sequence, and think 'Water Wins' - water infiltration will always find the weakest point, so proper flashing sequence is critical
