70/35 Solar glass

[SLW]

Hi - we have just had some large sliding doors installed having ordered the solar protection spec 70/35. Is there a way of seeing/testing that what has been installed is actually 70/35 and not just 'normal' glass? We are not able to gain appropriate assurance from the installer. Thanks

I had the same concerns with ours - similar spec. In the hot sunny days I thought the glazing did a good job vs opening a door and letting the sun hit me. I wonder if you could use a temp sensor of some kind placed behind the glass and then open the door/window and see what the difference is? Am sure there is a better way so look forward to hearing about that 🙂
