Our Recommendation
What We Recommend for Florida
Single-Story Homes
Go Single-Hung
Single-hung is the most common and cost-effective choice for single-story Florida homes. Excellent sealing, lower cost, and proven performance in Florida’s climate.
Two-Story Homes
Consider Double-Hung
Double-hung makes sense for two-story homes where cleaning upper windows from outside is difficult or unsafe. The tilt-in feature is a genuine convenience advantage.
