Temper. We are replacing windows at present and it has been dangerous dealing with ones we've accidentally broken That were not tempered. True, the likelihood of having to handle once new are installed is nil but if your budget allows. I would encourage you to go that route.

I would choose temper. All you need is just one of those 30 windows to break and you'll be kicking yourself you didn't spend the $6,000.

Pretty much a cut and paste from the other spot for me...

We always tell folks that if you have a specific room that the children
might roughhouse in, tempering is cheaper than a surgeon or plastic
surgery.


That being said, I only broke one window (via rock) growing up. I would
just reduce the unit size slightly and get below their recommended size
where they specify tempered glass.

I would be hesitant to spend $6 k on tempered glass, I don't know your exact circumstances but that is a lot of coin.

An alternative would be to install safety film on any window that you want to protect from shattering, e.g. in children's rooms. It would cost a fraction of tempered glass.

Many window manufacturers do not allow for after-market films to be applied to the glass, and doing so may void the warranty. I’d be sure to check that out prior to application of any films.

That would not be fun installing on those SDL's.

I had six 43x72 Marvin Ultimates Replacements installed with the tempered glass.. Yes, it brought a tear to my eye as I wrote the check, but with landscapers, window cleaning companies, and yard workers being near them, I am glad I did.. Also I have learned the home inspectors are pointing out tempered vs. non-tempered Windows to potential buyers.
