thermal imaging and insulation: This Much Missing Insulation Can Influence A Whole Room
- 03/21/17 01:45 AM
This much missing insulation can influence a whole room. It doesn't seem like a lot, but with insulation just a little that is missing goes a long way toward dramatically increasing energy bills. This subject house was advertised to have had a new roof installed just a few years ago. It was an older townhouse, and going into the attic space it was obvious that much of the sheathing had to be replaced along with the shingles. That likely was the result of the roof shingles being very old at the time of replacement. The previous roof may have leaked substantially, rotting the roof sheathing below. It … (8 comments)
thermal imaging and insulation: You Have To See Everything Because A Thermal Image Alone Can Fool You
- 02/07/17 04:07 AM
You have to see everything because a thermal image alone can fool you. It wasn't a cold day out, about 45F. And it was cloudy. Breaking out Mighty Mo to do the thermal image sweep of the insulation in the house, this is what the ceilings looked like on the upper level. The roof rafter joists are visible as the purple lines, with the insulation filling the gap between. The temperature difference between the insulated areas and the wood joist rafters is not very different. Does this appear to be a well-insulated space? To know for sure you have to look into the attic space! Does that look … (7 comments)
thermal imaging and insulation: Things We Did Not Know About Insulation Before Thermal Imaging
- 07/13/16 09:46 PM
Things we did not know about insulation before thermal imaging. I got into thermal imaging about 14 years ago because my son was on his second all-expense-paid-trip to Iraq and told me about some of the fun tools he used. Some of those tools included thermal imaging. He thought a thermal camera might be useful during home inspections. I had never considered it, but looked into it, and found that there was a big thermal imaging industry out there. But I also found that few home inspectors used thermal cameras. Looking into all the manufacturers, and many styles and high costs of the units … (12 comments)
thermal imaging and insulation: The 5% Rule Of Missing Insulation
- 01/19/16 05:48 PM
Many insulation studies have come to the rule of thumb consideration that can be called The 5% Rule of Missing Insulation. Basically stated, if a given area, say a wall or ceiling in a room in a home, is missing 5% of insulation, that missing 5% will cause a more than 50% loss in R-value for that area. To repeat: More than 50% loss in R-value for that area. That is substantial! Let's say you are in newer construction, and there because the homeowners have called about cold rooms. If Mighty Mo is tagging along doing a thermal image sweep of the house to check on … (11 comments)
