We have absolutes in life that we can’t just avoid. We have the sun, the moon and the big blue bouncing ball titled planet E. Yes here on this out of control globule we have to deal with the effects of the sun. We can stay indoors, we can hide in a tent, or even be draped in mink from head to toe.

R30 is a rating for the resistance of the suns affect on either our skin and/or a piece of material. It prevents the heat load transfer that the sun creates. Whether it’s radiant heat or direct heat. Meaning, it’s either directly penetrating the structure or the structure itself is so hot it is radiating that heat.

The roof of a house can reach temperatures far exceeding hundred and 50° thus the inside lid that of that would where the roof shingles reside can be about the same temperature. That means the inside space of that attic can be extremely hot to say it mildly. Although there are ways to eliminate this onslaught of heat but being aware of the facts is what this article is all about.

I’m an advocate of one and a half times the minimum when it comes to the R-rated elements of materials to protect from the sun and its side effects. There are R-rated charts for the requirements in each state. Here in California it is 30 to 60 R-rated depending on the area and depending on the attic space (how high your attic is)

Homes built in the 50s and 60s had a very low attic which creates a tremendous heat load factor in that area. Without proper attention to the those lacks of construction at the time you will always have a hotbox of a place that you live in. And I’m only talking about the addict nothing about the sidewalls or the crawl area if applicable.

Just dealing with one thing at a time would be the way I would approach this matter. And again the reason for this attention is to be aware of your will save money, anguish, and produce a environment that is more conducive to creating and having fun without the onslaught of some heat wave.

Doubling down is the most cost effective way to say money over the long haul.
