Blown Attic Insulation

The big misconception is that people generally feel that if two insulation products have the same R value, then they must be the same, but they are not.

For example, during sub-zero temperatures, fiberglass insulation loses up to 50% of its R-value, where cellulose insulation gains a little when the temperature drops below zero.
R value is determined by tests done in a lab under a controlled environment.

It measures the conduction, the thermal resistance of heat as it transfers through the insulation product.

This does not include the insulation’s ability to resist air from passing through it.
The intention of the insulation is to stop the transfer of heat.

Types of Blown Insulation

  • Blown insulation (also called a retrofit insulation or an insulation upgrade) in this method, we drill through the existing walls from either the outside or the inside of the home or building. If the exterior walls are drilled, there may have to be siding removed. Aluminum siding pieces can either be cut out and replaced or drilled and plugged. Both are effective. The drill and plug system are more cost effective, but there are visible plugs in every wall cavity of the home. When the aluminum Is removed, this takes more time in labor, but looks better. So, you really need to decide which is more important. Many homeowners choose to drill and plug, because they plan on upgrading the siding in the future. If vinyl siding is on the existing building, a piece can be removed where the holes are to be drilled. Once the insulation is installed, the holes are plugged, and the vinyl siding is reinstalled (like no one was ever there). If wood siding is on the home, this will have to be either drilled or removed and replaced. There is some risk that the pieces will crack. So, it is good to know that and try to locate some replacement pieces for the project in case some are damaged in the removal process.
 
  • Loose fill Insulation – for new or existing structures, this method is where an open attic floor is covered with an even covering of cellulose. Code requires all ceiling recessed lights to be ICIP Insulation protected cans or led as to reduce the risk of overheating. If you are installing lights, please keep this in mind. If you are not sure, we can take a look for you.

Cellulose insulation is the most effective and the most cost effective blown insulation for keeping energy costs down. It also helps keep your home comfortable and safe because it’s made from recycled newspaper. Cellulose is great for sound dampening, fire resistant, it prevents mold and mildew, and keeps out insects and rodents.

The R-Value of Cellulose is 3.8 per inch giving you an R-13.3 for 2×4 wall cavities and an R-20.9 on 2×6 walls.
