Do i need to use a Vapor barrier over garage insulation?
A vapor barrier in sidewall insulation is almost always a good idea.
Where is the radiant barrier located?
Radiant Barrier is essentially insulation that can be found anywhere where regular insulation is installed. Radiant barrier is foil and can often be seen covering duct work.
Can roll aluminum insulation be installed on top of blown in insulation?
Fiberglass and cellulose insulation work by slowing down heat transfer from one source to another. That's why the thicknesses of those insulation's are crucial for performance. Also, fiberglass and cellulose only resist heat transfer, they don't block or reflect it so it eventually escapes through. Perforated radiant barrier can be installed over top of existing attic insulation to form a reflective cover to enhance your other insulation. When installing radiant barrier over the attic floor you must use the perforated radiant barrier for maximum breathability. Moist air that is created inside your home must be able to escape as it rises through your ceiling. If a perforated radiant barrier is not used, the moisture will be trapped in between the barrier and your ceiling. When trapped this will cause condensation to form inside the building materials and insulation creating damage and mold. - EcoFoil
When installing insulation be sure to?
When installing insulation be sure to install a vapor barrier on the correct side of the insulation for the region in which you are located.
Where can I buy radiant barrier insulation in the SE Florida area?
You can find this type of insulation at Radiant Barrier Products. 631 Tuten Trl, Orlando, Florida. (407) 382-4737.
Can you put kraft faced insulation in your attic over already installed blown in insulation and if so would you put the paper side down that is toward the rooms below?
I went to a seminar about attic insulating materials and this is what I learned. If you already have blow-in insulation in your attic you shouldn't need more fiberglass. Instead, you will want to install a reflective radiant barrier insulation. Fiberglass and cellulose are designed to slow down heat escaping so you eventually lose most of your heat through the ceiling regardless. You need something to re-direct the heat once it passes through the blow-in insulation. Radiant Barrier will reflect a majority of the heat back once it escapes your blow-in insulation. I bought some Ecofoil online and just rolled it out over top of my existing blow-in insulation, it was very easy.

Vapor barrier over studs and insulation and behind drywall or over drywall?
Vapour barrier is directly onto studs.
What is a Radiant Barrier?
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.
What direction should the vapor barrier of insulation be installed?
towards the inside of the building

What is the best type of insulation?
The Best Type Of Insulation is Spray Foam Insulation. Because Spray foam insulation, also known as polyurethane foam insulation, is a superior form of insulation that provides a higher thermal insulating value (also known as R or RSI value) than conventional batt insulation. The application ensures that any gaps are sealed, providing a vapor barrier, moisture barrier, air barrier and even a radon barrier, thus stopping any thermal loss due to drafts or leaks. This makes spray foam up to 50% more energy efficient that other insulation solutions, resulting in cost savings on energy and gas bills. It is important to understand that a lot of the heat or cold air loss happens due to the air leaks on your walls or roofs, and that the cheaper batt insulation installation is quite susceptible to leaks if the vapor barrier (that layer of poly plastic applied just before the drywall) is not properly installed or if it becomes damaged. Further, unlike batt insulation, spray foam barrie insulation does not shift, sag or become wet or moldy. Rather it adds to the structural integrity of the house, with the added benefit of keeping out pests or vermin. For More Details Visit sprayfoammasters.ca
Do you put the vapor barrier of insulation on the inside or outside for an exterior wall application?
Inside, after the insullation, and wiring
