A common worry is that impact windows are sealed shut. They are not, many styles open and close like any other window.
Operable styles
Single-hung, horizontal roller, casement and awning windows all come in impact versions. Fixed windows do not open by design. See types of impact windows.
Egress in bedrooms
Building codes require an emergency escape opening in sleeping rooms. The opening must meet minimum clear size and sill height rules. Casement windows often give the largest clear opening for their size, but several styles can meet code depending on the dimensions.
Weight and operation
Laminated glass is heavier than standard glass, so quality balances and hardware matter. A properly installed window should operate smoothly and lock securely.
Plan it early
- Tell your installer which windows are in sleeping rooms.
- Confirm that selected styles and sizes meet egress rules.
- Check HOA rules on style and color.

What egress requirements typically say
Building codes generally require each sleeping room to have an emergency escape and rescue opening with a minimum clear opening area, minimum clear width and height, and a maximum sill height above the floor. The exact numbers are in the Florida Building Code and your local amendments. The purpose is to let someone climb out, or a firefighter climb in, in an emergency.
How window type affects clear opening
- Casement: opens fully, so the clear opening is often close to the glass size.
- Single-hung: only about half the height opens, so the window must be tall enough.
- Sliding: only half the width opens, so it must be wide enough.
- Fixed: never counts as an egress opening.
When you replace a bedroom window
Replacement windows generally need to meet egress requirements at the existing opening where applicable. Tell your installer which rooms are bedrooms so the product choice and size are checked before ordering.
Security and egress together
Impact windows can still have easy-to-use latches that do not need keys, so occupants can escape. Avoid adding extra locks that need a key to open from inside a bedroom.
