Not many people today right now are unable to keep in mind a time when among the list of leading types of home insulation was not fiberglass. It is because it has been all around because 1938 when it was initial launched by Owens Corning.
Prodex reflects ninety seven% with the radiant Electrical power (Most important source of heat move) that strikes it. Prodex also reflects back again the warmth within your dwelling.

Martin, We may just be having a semantic disagreement. Inside of a cooling climate, stopping solar Electrical power from heating the roof plus the attic is attractive.
The hotter and sunnier the weather, the greater proficiently a radiant barrier will function, equally to manage the indoor local climate and decrease the quantity of Electricity employed to do so.

I commend you for every one of the retrofit do the job that you are accomplishing in your attic. It sounds like you will be accomplishing all the correct issues.
The simplest way to comprehend it is in the analogy of employing an umbrella in the Beach front. Though you may however feel the heat, the umbrella absorbs nearly all the sun’s rays and keeps you from having overheated as swiftly.

Radiant barriers that aren’t facing an air Place don’t perform. If it’s sandwiched in between a layer of sand as well as a concrete slab, it’s a conductor, not an insulator.
The greatest dilemma with exaggerated statements of cost savings from radiant barriers is that after folks feel they've been hoodwinked, They are fewer likely to believe that other more practical Electricity effectiveness methods.

The partitions of the house were being insulated with an item made by Reynolds Aluminum... Arriving in extended flattened rolls of Air conditioning aluminum, they have been Lower to length then popped open up by pulling alongside the flanges at the perimeters.

I've examine with interest the responses flowing back and forth. and very good exchanges with a topic that we can master from. I'd interject that we have been spending an excessive amount of time and positioning too much enphasis on "R worth". the comfort and ease level in a home plus the Electrical power we get to acheive what we drive are the base to work off of. R benefit is simply a Device that can help forecast that and not a true science. Insulation profits like the word and many of us buy into it since it retains bringing us again to insulation plus more product sales. and it is a snap for advisors to convey, include far more insulation and all might be well. The brand new merchandise is spray foam and we can easily argue the merits of open or shut but we nevertheless sell insulation.
