What is the difference between single-hung, horizontal roller and casement?
A single-hung window slides up, with the top sash fixed. A horizontal roller slides sideways. A casement swings out on a crank and seals tightly. In bedrooms, the window has to open far enough to meet egress rules, which favors casements and large rollers. The choice affects the look, the airflow and cleaning.
What is Low-E glass, and is it worth it?
Low-E glass has a thin coating that reflects heat while letting light through. In Florida, it cuts how much sun heat passes into the house, which helps the air conditioning. It is normal in new windows and usually a small extra cost. The coating can tint the glass slightly. Ask to see a sample.
What do the U-factor and solar heat gain numbers on the label mean?
The NFRC label rates how well a window keeps heat out. U-factor measures heat flow, and the solar heat gain coefficient measures how much sun heat passes through. Lower numbers are better in Florida's hot climate. The energy code sets limits, so the label is checked as part of the permit.
Does an enclosed balcony change the rules?
It can. Closing in a balcony creates new floor area, which may need a permit and engineering, and the windows must meet wind and egress rules. In a condo, the association's approval is needed too. Treat it as a small addition. It needs plans, approvals and the right windows.
Does a standard window still need a product approval?
Yes. Every window installed in Florida needs a product approval from the state or Miami-Dade, listing its tested design pressure and how to anchor it. The difference is whether the glass is impact-rated. The approval and its label must be on file for the building inspector.
What changes when a garage becomes living space?
Habitable rooms need natural light and ventilation, so a converted garage generally needs windows of a certain size, with part of that opening operable. Some of the openings may also need to serve as emergency escape. The plan reviewer checks all of this, so the windows are drawn into the conversion permit.
Will I need to repaint after the windows go in?
Often yes, at least around the frames. New frames leave stucco patches and some exposed edges, and a patch rarely blends into old paint. Repainting the whole wall gives the best result. We can quote the patch alone, or patch and paint, and you can decide once you have seen the survey.
Can I choose grids or a different color on the inside?
Grids come in several patterns, usually set between the glass or on the surface. White is the common frame color, and dark exterior frames are available in many lines. Two-tone frames, with a different color inside, can be specified but add cost and lead time. Choose at the selection stage, before the order.
