Can insulation R-value be too high? ›

The answer is yes! Past a certain point, insulation in a vented attic will do more harm than good. In most of the United States, achieving an R-Value of 38 is more than sufficient. In the temperate Southern California region, an R-Value of 30 tends to be ideal.

What are the problems with PIR? ›

Bugs or wind can interfere with PIR sensors

As silly as it sounds, bugs and other animals can trigger PIR sensors, causing false alarms or generating incorrect attendance data. Powerful wind can also penetrate the sensor mechanism, causing problems with the sensor's ability to properly detect movement.

What can block a PIR sensor? ›

A simple silicone spray will blind the sensor, and is invisible to the naked eye. It leaves a trace, but it might not be discovered until much later, if at all. Alternatively, you could place glass in front of the sensor when it was off, which would do the same thing.

What type of insulation lasts the longest? ›

Spray foam insulation is one of the most durable, effective, and reliable forms of home insulation. It can last a lifetime or longer. Because it is mold resistant and does not hold moisture, it doesn't move around and typically stays put until physically removed.
