In constructing a house or a building, one of the factors you need to consider is ventilation and temperature regulation. In the attic of a house, you would have problems during summer due to how hot it is there or basically just in the roofing area. Construction companies may offer you a few options but you also need to know what these options are before agreeing to them.
The companies may offer different insulation materials for your attic. They might offer you radiant barrier paint as an option. Although the term radiant barrier itself is a technology developed from space exploration, the spray on would only reflect about five to seventy five percent of the radiative heat.
Radiant Barrier or Reflective Insulation was developed through space exploration. The tested rate for it to reflect heat is about ninety percent. For it to be called as such, it should be around that range, but since the paint can only reach from five to seventy percent, this would not be qualified.
So, in terms of space exploration, it is more utilized in outer space. This is due to the material being responsive with radiative heat instead of up to forty six percent convection or conduction that is happening on earth. Basically, how effective it is would be determined by the levels of radiative heat.
The given definition from the American Society of Testing and Materials International is that there is still no known product that is qualified as radiant barrier. For it to be considered, it should have a low emittance value of 0.10 or lesser and reflect about ninety five percent of the heat.
The usual materials which are wood, fiberglass, and masonry have about 0.8 or more. This means that they have higher rates for transferring radiative heat. Basically, 0 level is the lowest emittance with 1 being the highest. So each material can and may be tested accordingly if they have these levels.
If you really want to use the spray on in your attic, just know that it would cost you an insane amount of money with the less efficiency and effectiveness. A different option would be using foils. Here comes the difference between Quality Assurance and Quality Control, where spraying it and hoping it would work would be far better than just making sure the foil is installed correctly.
There are instances when the contractor you hired would offer the paint to be mixed in with water, which is called cutting. This is by no means a good practice. The composition of this are bits and pieces of aluminum grounded and fined then mixed with clear paint, so when it dries it only leaves the aluminum. Adding water to it would end up diluting and making it even way less effective.
A lot of products are being sent out in the market that are not properly tested. It only takes further steps in making sure that you are getting the right ones, or rather, choosing the right material that would deliver results. Although if you insist on using sprays, make sure it is installed professionally due to its hazardous airborne chemicals, and also checking the testing data, level of emittance, and if they were monitored in the American Society of Testing and Materials International.
