Spray on radiant barrier is not only expensive but performs only half as good as rolled radiant barrier. I was going to have my attic sprayed until I went to a seminar on rolled radiant barrier. They showed a video of test done in the same attic with one side sprayed and the other side rolled radiant barrier. They had a digital heat reader on both products and the difference was almost 20 degrees in 5 minutes. So I went online and found some rolled radiant barrier called ECOFOIL from www.ecofoil.com. Easy to install and really keeps my living room cooler.
Radiant Barrier is fairly cheap if you look online. I did my attic this spring and at that time the cheapest was from www.ecofoil.com at $125.00 / 1000 s.f. I didnt need to add blow in but I think its around $5 for 16 cubic ft.
The cost of installing radiant floor heating can vary widely based on factors like the size of the project, the type of system, and labor costs. On average, the cost can range from $6 to $16 per square foot for electric systems and $10 to $20 per square foot for hydronic systems. Heating a typical room can cost between $1,500 to $5,000.
That depends very much on what kind of radiant energy and how much of it you get. A large dose of radiant gamma radiation is very unhealthy. A moderate amount of sunshine (which is radiant energy) is good for you and promotes the production of vitamin D. Too much UV radiation will give you sunburn and can cause skin cancer.
Radiant heating works by transferring heat directly from a warm surface to objects and people in a room. This can be done through electric resistance heating, hydronic heating (using hot water circulated in pipes), or radiant panels. The heat radiates outwards, warming up the surrounding area without the need for forced air or ductwork.
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.

$50 at Gamestop. The price may change.
Solar screens are woven more losely to allow air to pass through more freely. Therefore they provide slightly less reflectivity of solar heat rays. Depending on where you are wanting to install the product, the radiant barrier will be more effective but I dont know if it will fit your application for sure. I have ECOFOIL radiant barrier installed in my attic and it keeps my air conditioning bill much lower in the summer.
They cost about 10$ per can if you buy from The Home Depot.

around 60$ for the fluid service.....
A radiant barrier is a thin sheet of highly reflective aluminum comprised of one or more layers (for puncture and tear resistance) that, when installed properly, will block at least 90% of the radiant heat that hits it.Radiant barriers are unaffected by humidity or ambient temperatures, unlike other forms of insulation, and therefore perform at a consistent level at all times.When installed in an attic, a radiant barrier reflective foil insulation products can reduce attic temperatures by up to 30 degrees when installed to the underside of roof rafters. Lowering attic temperatures provides a significant benefit by reducing air conditional loads and energy usage. Attic insulation radiant barriers can also:Reduce heat transfer from attic to living spaces by up to 50%,Extend the life of air conditioning units, andIncrease the comfort level of a home.Radiant Barrier Definition : Per the Department of Energy (DOE), a product classified as a "radiant barrier" must have a low emittance of 10% or less and high reflectance of 90% or more.Emittance (or emissivity), refers to the ability of a material's surface to emit radiant energy. All materials have emissivities ranging from 0% to 100%. The lower the emittance of a material, the lower the heat (infra-red radiant energy) radiated from its surface. Aluminum foil has a very low emittance, which explains its use in reflective insulation and radiant barriers.Reflectance (or reflectivity) refers to the fraction of incoming radiant energy that is reflected from the surface. Reflectivity and emissivity are related and a low emittance is indicative of a highly reflective surface.RadiantGUARD®radiant barrier products BLOCK 97% of the radiant heat - much higher than the DOE minimum reflectance criteria for a radiant barrier product.
Renting one is much cheaper. Good ones cost hundreds.
