The good stuff

Why homeowners love single-hung windows

Easy on the budget

With only one moving sash, single-hung units are among the most cost-effective ways to protect every opening in the house.

Familiar and effortless

Lift to open, lower to close. No cranks or tracks to think about. It works the way most people expect a window to.

Quietly strong

Laminated glass stays bonded to its interlayer if it's struck, so the opening stays closed through a storm.

Protect every opening in the house without overbuilding the rooms that just need light and air.

Single-hungs shine in the rooms where you want dependable light and ventilation without the cost of more elaborate hardware. They're also the natural like-for-like replacement for the aluminum single-hungs found in many South Florida homes built before today's code.

Questions

Good questions, straight answers.

Yes, as long as the specific product carries a Miami-Dade Notice of Acceptance (NOA). Both counties sit in the High-Velocity Hurricane Zone, and Haven verifies the NOA number for every unit before it's ordered.

On a single-hung window only the lower sash moves; the upper sash is fixed. On a double-hung, both sashes move. Single-hungs have fewer moving parts and seals, which keeps cost down and makes them a popular choice across South Florida.

Often, yes: if the opening is large enough to meet the Florida Building Code's emergency-escape requirements. We measure each bedroom during the free estimate and recommend a larger unit or a casement where needed.

They can. Florida insurers commonly offer opening-protection credits when every window and door is protected with NOA-approved impact products. We provide the NOA numbers and closed-permit documentation your agent will ask for.
