Hello,

I just had new vinyl double pane windows installed. Out of curiosity, I thought I (technically my caregiver) would check the temperature around each window with an IR laser point thermometer. I was very surprised to get consistent low temperature readings on the edge of the window by the trim. This is possibly normal, but I want to get an educated opinion. I'm a quadriplegic on a fixed income, and this was an expensive renovation for me.

Here's a video showing the temps around one window (sorry it's sideways). And for reference, it was about -20 Celsius outside, and 70 Fahrenheit inside when this video was taken.

Any assistance is greatly appreciated.

Thanks,
Cam

A 10 degree temperature differential across a surface that only has an R-Value that is much less than the wall around it isn't bad at all.

Especially if you are saying it -4 Fahrenheit outside. That would be excellent performance at that point. Its also not surprising that it is colder near the counter top. Less air movement and access to conditioned air, the cabinets are usually poorly insulated, and its a generally colder area.

Thank you very much for the quick reply. And also for an answer I was hoping for :).

Hi Quad,
First, those numbers don't look bad to me and I frequently use infrared to look at temperatures. I use a camera so I get everything at once.

The other issue is the spot size of that IR meter. Most IR thermometers sample a cone that varies in size with distance. Closer is smaller. The red dot is probably just the center. Your manual should indicate the area of the reading at the distance you are measuring.

Bottom line, they did a good job, IMO.

Thanks, Bud. I'll take a look at the manual. Like a typical man, I haven't yet :surprise:.
