Yes, unless the edge of glass at the bottom of window is greater than 60” from the floor on the inside or outside.

Ask your local building official.

Tempered requirement can be one choice. Laminated is also likely an option. Could be less cost because the material is widely available and easier to fabricate. Think car windshield. It's also a better security choice.

In addition to what Todd said about the bottom of the glass in the window being above 60" from the floor, if the panel that is closest to the window is fixed then you don't need safety glass in the window because glazing that is adjacent to a fixed panel of a patio door is exempted from the tempered / safety glazing requirement.

However I also agree with Mark Bishak, ask your building inspector what is required for your area.

I am assuming that slider is a door , but maybe not ?

Laminated glass is available from glass fabricators in my area. These guys aren't national brand manufacturers. The glass is used for patio door glass replacement. It's cheap. I've talked to tempered glass producers. They put restrictions on who they prefer to deal with. If you can make this window a fixed unit, the cost could be reasonable if you go laminated. Swapping out a replacement pane is where I'd start the price comparison.

@toddinmn - Itt'l be a slider or folding. Thanks.

Glazing requirements is a confusing section of the IRC. Check with your building official to be sure your interpretation of the requirements aligns with theirs or just call for it to be tempered and be on the, well, safe side.

it must be tempered.

Agreed if the bottom of the window glass is less than 60" above the floor (which it does appear to be in the drawing) or if the sliding door panel closest to the window is an operator, but if the door panel is fixed and if the window glass is above 60" from the floor, then safety glass would not be required per IRC 308.4. Local codes could vary of course.

@oberon476

my apologies, you are correct! Had not seen the 60" off floor exception for doors

R308.6.2 Materials. The following types of glazing shall be permitted to be used:

1. Laminated glass with not less than a 0.015-inch (0.38 mm) polyvinyl butyral interlayer for glass panes 16 square feet (1.5 m2 ) or less in area located such that the highest point of the glass is not more than 12 feet (3658 mm) above a walking surface or other accessible area; for higher or larger sizes, the interlayer thickness shall be not less than 0.030 inch (0.76 mm).

2. Fully tempered glass.

3. Heat-strengthened glass.

4. Wired glass.

5. Approved rigid plastics

Laminated glass. Laminated glass is usually constructed with an inner layer of polyvinyl butyral, which has a minimum thickness of 0.030 inch (0.76 mm). Such glass is highly resistant to impact and, as a result, requires no further protection below. When used within dwelling units, laminated glass is permitted to have a 0.015-inch (0.38 mm) polyvinyl butyral inner layer if each pane of glass is 16 square feet (1.5 m2 ) or less in area, and the highest point of the glass is no more than 12 feet (3658 mm) above a walking surface or other accessible area.

Tempered will not meet Miami-Dade Hurricane requirements. You'll need laminated. Laminated provides intrusion protection, tempered does not.

@Jeffery R. Genz, no problem!

@Dan1888, I don't think that anyone would disagree with you that laminated glass is a great optional choice as a safety glazing product, however stating that laminated is a cheaper option than tempered really isn't very realistic.

Tempered glass is a single lite that's heated in a furnace up to about 640-680C and then rapidly cooled to introduce surface compression and center tension layer into the glass. Not quite as simple as it sounds,, but modern furnaces rely on computers to control the process.

Laminated glass consists of two layers of glass enclosing a vinyl or other type of interlayer. Laminated glass is also run through an oven where it's heated under pressure in order to remove air and moisture (as much as possible) from the interlayer and then to bond the interlayer to the glass. Following the oven the unfinished laminated glass gets to spend a couple of hours in a giant autoclave to finish the process.

Key being tempered = 1 lite and laminated = 2 lites plus interlayer, and the cost of the raw interlayer is more than the combined cost of the two lites that enclose it. Hard to imagine how the single lite can cost more than the two lites plus more expensive interlayer.

You are correct that tempered doesn't meet hurricane impact requirements, whether MDCA or ASTM 1996, but neither does laminated glass using the interlayer thicknesses that you mentioned in your post.

I also agree that laminated is better than tempered for both safety and security, but the OP's original question had nothing to do with hurricane impact protection or security, only asking if safety glass would be required for their application.

Also only laminated and tempered of the list that you posted are considered to be safety glazing; heat strengthened and wired glass are not.

For reference, IRC 308.6 is all about skylights, not vertical windows. The information in your post about IRC 308.6.2 is not applicable to the OP's question.

It depends on which panel on that door is operatable. If the window is less than 24" from the operatable panel you need tempered glass.

@dan1888, I work with and price glass and glazing pretty much all day everyday. In no world has or is laminated less than tempered cost wise.

The drawings should make it clear how windows and door operate for the building inspector and the contractor.
