[MassHistPres] Impact Resistant Windows

[heartwood]

hello anne....

impact resistant glass is typically available in two forms:

laminated—two thin panes of glass with a film between...upon impact, the film
maintains the pieces of shattered glass...

tempered—heat treated glass...not unlike your windshield that breaks into small rounded
pieces of glass to minimize injury...
try these folks: AGW Old Style Window Glass (agwglass.com)

I don’t recall where I purchased it but years ago I was able to get wavy laminated glass...

I have used regular (flat) laminated glass for a client who remodeled her bathroom in a 
configuration where a new whirlpool tub was directly below the window...the laminated glass I used appeared
as flat glass from both the interior and exterior, no distortion...it is slightly thicker than typical 150 year old glass...
the fit depends on the depth of the rabbet...the width of the glazing bar should not be an issue...

hope that helps!

Hi,

 

Seeking information for District Commission who have reviewed impact resistant windows in a local historic district.

 

Is there a visual difference between the impact resistant and standard window?

Does it affect the profiles?

 

We are trying to get a sample – and in this case it is a tax credit project to boot!

 

Thanks!
