It's actually more complicated than it seems. Here is a video explaining precisely how much insulation you need: http://www.YouTube.com/watch?v=oHg5SJYRHA0 It takes into account all of the variables (size, location, etc.) forget being technical. In most parts of usa(moderate climate) use a minimum of 8-10 inches. If you're in the far north or desert either one use a minimum of 12-16 inches. with the price of energy what it is and the comparatively low price of insulation you cant go wrong by using a lot. just stick your head up thru the access hole and measure what you have before installation, and after installation dont pay until you measure what you agreed was to be installed! a minimum of 12 inches even in a moderate clime is not to much. again more is better.

How Thick is R25 insulation?
R25 can be many different thicknesses. It depends on the insulation product. Styrofoam SM would need to be 5" thick. Pink fiberglass would need to be about 7" thick. White (beadboard) styrofoam would need to be about 6.75" thick. Blown in attic insulaton would need to be about 10" thick.
Improving Energy Efficiency With Attic Insulation?
Installing insulation in an attic will save between 10% and 50% on average for a household energy bill. With the recent encouragement to save energy, attic insulation has become affordable for everyone, making it a necessity for anyone who lives in a climate where extreme heat or cold is experienced. Hot and cold air often enters a house through the attic, then affects the rest of the house. The problem is more predominant in the winter seasons, as heat has a tendency to rise. When the heat rises to the attic from the lower levels, the energy is quickly lost instead of being conserved, if there is no insulation present. Consider insulation to be similar to covering a hole in a cup full of water. Insulation is fairly easy to install and may be done as a do-it-yourself project. Types of insulation are determined byway of an R value. This value determines what type of insulation is needed for each climate, depending on the normal weather patterns in that area. To determine the R value needed, consumers may consult the Department of Energy’s website for resources. Most home improvement stores or supply stores sell insulation and the supplies necessary to install it. Some stores may also have guides for consumers to purchase, offering complete instructions. Many people prefer blown-in attic insulation instead of batted, simply because it is much more quick and painless to install. Batted insulation may be more time-consuming and involve being in an uncomfortable posture longer, but it does produce a more uniform R value. Consistency is important with insulation, especially the more extreme a climate is. When preparing to install attic insulation, an entire day should be reserved to complete the project. Attics that are unfinished and have unreliable floor boards should have extra thick boards laid across in common walking areas. This will ensure safety during the installation process. Before purchasing insulation, it is best to see how much insulation is already in the attic’s spaces. Usually attics will have very little insulation or none; sometimes removal may be desired for a uniform result. Removing insulation is not recommended without the help of a professional.
How do you determine the insulation thickness for heat insulation?
It's about 25mm - 1" vermiculite thick layer for every 100 degrees Celsius temperature level. For 350C oven temp reach the insulative layer should be 70mm thick.

Environmentally Friendly Attic Insulation?
Every home must use insulation of some type, especially when an attic is involved. Attics are known for losing heat quickly, especially when the temperature is below freezing. Attic insulation comes in various forms, but the most popular is fiberglass, although better and more technological types of insulation have recently become available for home use as well. The newer insulation is also more environmentally friendly as well, although they do cost a bit more to employ but the cost savings can be dramatic.Recycled Cellulose Attic InsulationCellulose is a renewable resource and is one of the most environmentally friendly attic insulators available worldwide., Not only does it reduce heating and cooling costs, but it is also easy to sue and recycle as well. Additionally, using post consumer cellulose fill is even more environmentally friendly because it saves the manufacturers from needing to produce more, thus lowering the overall carbon footprint of the insulation as a whole. Using recycled cellulose means using materials from landfills and this will reduce the amount of chemicals released into the air from manufacturing other paper products. Waste paper is one of the biggest sources of cellulose so using it as an insulator for an attic is logical.All that is needed is enough waste paper or other loose recycled cellulose that has been treated with an environmentally friendly bug repellant and flame retardant spray to fill the needed square footage of the attic floor, for example. This works especially well if the attic is not used. Simply covering the attic flooring with the cellulose will be enough to keep the heat and cool air downstairs where it belongs.Downfall to CelluloseOne thing to keep in mind, though if cellulose s in fact used as an attic insulator is that if it rains and the attic leaks, the insulator may rot and mold. Because cellulose is a natural fiber, it can soak up water as any other paper would. This means that any leaks in the attic should be sealed before applying the attic insulation otherwise the project could turn messy and hazardous as well.Overall, recycled cellulose is a great choice for attic insulation projects. It is relatively cheap since a person can simply cut up their old newspapers and treat it with the environmentally safe treatments, It is also very easy to apply because simply spreading around enough to cover the floor up to a few inches thick is enough to keep costs down while saving the Earth.
