I love these videos! I started working in the millwork department at HD a few months ago and there is so much to learn. I just had a customer come in who is building ADU on his property and he failed inspection because he didn't order windows that meet the fire code in his area. In California, if you live in a fire zone, the windows need at least one of the panes of glass to be tempered. Next week we will be ordering his replacement glass for his windows. An expensive mistake for a first time owner builder who didn't read the fine print on the blueprints his architect provided him.

Great topic. I have 2 windows about 19 inches from the back door that need to be tempered. A couple of the salesmen I spoke with were clearly confused on the tempering requirements. One told me those windows didn't need to be tempered. The other told me that the 6 windows on the front that are only 10 inches from the floor need to be tempered...but the bottom sashes will only be 6 sq ft. so they don't need it. I ended up buying from another company. I'm glad I did my research before hand.

Great video Jeff!! This is one of my favorites of all your videos. Safety glazing was a specialty of mine and an area that I dealt with everyday before I retired (and several times after I did). I can't agree with you more that people need to pay attention to the requirement and if in doubt about the safety of a window then spend the extra few dollars and use safety glass. Ultimately a few extra dollars for the safety glass is a lot cheaper than an emergency room visit and a hell of a lot less painful than watching your child or grandchild or even pet in an emergency or operating room. I applaud your decision to decline selling a window without safety glass for a safety glass application! 👍👍👍 One add-on is that laminated glass also meets the requirements for use as safety glazing and can be used in almost any application that tempered is approved for. Car windshields for example are required to be laminated (windshields never use tempered glass in any form), while side and back windows can be either tempered or laminated. And one FYI about the wired glass that is so prevalent in some schools and public buildings is that wired glass is NOT safety glass and should NEVER be used in a safety glazing application. In fact that stuff can be even more dangerous than ordinary annealed glass when used in the wrong application.

I ordered 22 Windsor windows a month ago for our forever home we're building here, in Ohio. Thanks for all your help the past couple years we've been working on this.

Excellent, excellent video Jeff, thanks for posting this info.

Great video with images. I was a little confused when I read the code. I have a landing that turnes 90 degree. A 36"x36" window on the landing. Its 8 inches off the floor. Minus the frame its under 9sf. My understanding is it doesnt need to be tempered. Still a little dangerouse so I will be adding spindels to match stairs and make it safer. A kid could fall down the stairs and go through it.

Here is a question from a window cleaner. How should I clean them to look as good as possible. 1 - Can I use a scraper if there is paint on them? 2 - Can I use walnut pad on them? 3 - In the industry with have 0000 steel wool that is super fine and does not scratch regular windows-will it scratch the Tempered? 4 - Will white vinegar damage them? Most cleaners add a little to their buckets of water. Also, tell me ways to know if it's tempered without a marking?

Another great video. Crazy how expensive Tempered glass is... has it always been this pricey?

Would tempered help from a small rock popping from my Gardner lawnmower and hitting the window?

We reside in CA and are now obtaining quotes for replacement windows. Have received 3 quotes with conflicting information regarding which windows require tempering. We will be replacing a 72 x60 sliding window. There is an inswing door that leads to a small patio that swings right onto the wall where the window is. With the door closed, the measurement is 40" from the door to the left side of the window and frame. Does the 2' rule apply to the door when it is opened, or closed? Does this window require tempered glass? The building code states: Within a 2’ arc of either the edge of a door and where the bottom exposed edge of the glazing is less than 60” above the walking surface. We want to do what is required to meet code.

What glass would you use on boat portlightis 5"x15"?

I would love if you'd address the fire resistance of tempered glass. It seems that since we were burned out in the CampFire of 2018 the code wants all our windows to be tempered. Does it really help in fire situations? How much?

How much is it for tempered glass window . About 30 × 24 inches and how much is it to install

Nothing needed but a steel tip dart. There's all kinds of "window people" in DFW, just ignoring this little detail. Kinda like they ignore RRP.
