What kinds of accessories are used in full conduit wiring?

If the conduit has reached its limit as to how many wires can be in it, there is only one course of action and that it to install another conduit parallel to the existing one. The electrical code book only allows a certain cross sectional filling of any conduit size. The rule is based on the dissipation of heat from the conductors in the circuits through the conduit walls. Once the wire fill has reached that figure no more wires should be pulled in because of insulation heating. Over time the heating of the insulation could lead to insulation breakdown and then short circuiting of the existing conductors that are in the same conduit.

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

How much blow in insulation needed for 12' x 14' attic space?

It is difficult to give an answer in terms of number of inches or total volume / number of bags required. For one thing, it depends on how deep the insulation is, i.e. it takes twice as much to make it 6 inches deep as it does to make it 3 inches deep. The deeper / thicker the insulation, the more it insulates. This is usually expressed as an "R-Value" where a higher value is more insulation. Note also that there are different kinds of blow-in insulation, e.g. fiberglass and cellulose. These have different properties and require different amounts to achieve the same thermal effect. One easy way to figure this out would be to go to the store where you plan to purchase the insulation and look at the bag. The bag will have a chart that shows the square footage or dimensions of the space to be insulated and the number of bags required to achieve various R-Values. If you know the company who manufactures the insulation, you can check their website. It is quite likely they have a similar chart of calculator as well.
