When you are planning for a good ventilation or temperature regulation inside your house or your attic, you would most likely have your contractor do all of it. You should try and monitor the materials being used though, so you would not have to pay too much for something that does not give exact results. Of course, you first have to know what kind they are using.
When it comes to your attic, you need to know the different types of insulation you can install. One thing that caught the attention of most people is the convenience of just spraying it. This can be quite tempting but in actual, the effectiveness of the radiant barrier paint would range about five to seventy percent only of reflecting the radiative heat.
This is also called Reflective Insulation which was, as mentioned, first used by space exploration. Basically, it should reflect about ninety five percent of the heat. So in the paint being as low as five percent, it would not be considered as radiant barrier at all.
The heat transfer here on earth through convection and conduction is about five to forty percent. With this in mind, how effective the material would depend on radiative heat, meaning it is more effective in outer space. This has a low emittance surface surrounded by air surface, which is the known factor.
Also, in regards to the definition from the American Society of Testing and Materials International, currently there is no such product that is available. So do not get fooled. The standards for a material to be considered radiant barrier is when it has low emittance surface level of 0.10 or lesser.
Materials have emittance levels for radiative heat. The levels are from 0 to 1, which 0 having the lowest emittance. For construction, like masonry, wood, and also fiberglass, the have levels around 0.8 or maybe higher than that.
Here is the thing with regards to Quality Control and Quality Assurance. The latter provides that you place the material and hope it works, while the other assumes that it is already effective but all you need to make sure if it is installed correctly. Such can be compared between the spray on and the foil.
Some contractors would provide you with materials you have not heard of or they might make it sound very pleasing to you. One of these might be the spray on, which is aluminum being finely granulated and mixed in with clear paint. And when the it dries up it leaves the aluminum on the surface. Be wary of cutting the paint, for this would dilute the mixture and could even more make it non effective.
So many promises in the market for these products regarding this sort of paint. Although none of them are actually true. If you do encounter a product though and insist on using this, make sure of the level of emittance, ask for data, and make sure that their products are tested by the American Society of Testing and Materials International.
