When done right, dense-packed cellulose is a highly efficient option for insulating exterior walls. It insulates as well if not better than the average batt (R3.5-3.8/inch), and slows air flow through walls making your house cheaper and easier to heat and cool.

Dense-Pack Cellulose Insulation Done Right How to tell the difference between a good cellulose insulation job and a bad one. By Jon Riley Issue 272 - Dec 2017/Jan 2018 My first weatherization job was helping my dad insulate and air-seal the attic of the old farmhouse where I grew up. Dense-packed cellulose insulation is a highly efficient option for insulating exterior walls. It has an average R-value of 3.5 to 3.8 per inch, providing excellent thermal insulation. Dense-packed cellulose acts as a sound barrier, offering better soundproofing compared to other insulation materials. Two representatives from National Fiber, Bill Hulstrunk and Chris White, share their tips for installing dense-packed cellulose in wall cavities. ( Recorded at the demonstration stage at NESEA 's Building Energy 13 conference in Boston on March 6, 2013) Cellulose insulation is made from recycled newspaper. In fact, dense packing walls typically results in remarkable performance. It is the dense packing of unvented cathedral ceilings or unvented flat roofs that is the problem. First, the good stuff. One of the most effective ways of dealing with existing uninsulated frame walls is to blow cellulose into the wall cavities.

Dense Packed Cellulose Insulation | Passive House Accelerator Construction Tech Copy link In this video, Kevin Brennan, co-owner of Brennan & Brennan Insulation and Airtightness and Construction Tech co-host, provides a tutorial on and onsite demonstration of dense packing cellulose for superinsulated Passive House construction. One of the best performing insulations on the market is dense-pack cellulose. This is a term used to describe a cellulose insulation product that can be densely blown in cavities between dimensional lumber. It is similar to blown in cellulose of years back without the accompanying drawbacks. In both damp spray and dry dense pack applications, the cellulose should have the feel of a firm mattress when pressed with the palm of your hand. In damp spray applications, low density, too much moisture, or poor spray technique can cause small gaps "sags" to develop, usually overnight, between the top plate and the top of the cellulose. In the dense-pack process, cellulose is blown into closed wall cavities at a relatively high density of 3 to 3 1. Cellulose insulation is receiving a big image boost from Louisiana-Pacific on two accounts. First, L-P is the first company to market cellulose insulation nationally; its Nature Guardâ„¢ product is produced at four.
Dense Pack cellulose in Modular building .. YouTube
The installer fills the cavities with dense-pack cellulose in a way that crushes the existing insulation without balling up the batts, achieving a full uniform application of the new cellulose fiber. The goal on any application is to assure complete coverage that is installed at a density that will not settle over time. How does it work? Dense packed cellulose works as an effective air barrier, slowing down movement of air through a building's thermal envelope to almost zero in some cases. Blower door tests have indicated that up to a third of a building's air leakage can be stopped after installing dense pack cellulose. Cellulose and Moisture
Dense-Pack Cellulose Coverage Chart Find the expected yield for any framing cavity you're likely to encounter. By Patrick McCombe Issue 272 - Dec 2017/Jan 2018 In order for cellulose to be self-supporting, it has to be installed at a 3-1/2-lb.- to 4-lb.-per-cu.-ft. density. How To & DIY Ideas & Inspiration Installation Planning Video All About Insulation Insulation in your home increases interior comfort, while decreasing heating and cooling costs. by This Old House Insulation helps to keep interior temperatures comfortable when it's unbearably hot or cold outside.
Densepack Cellulose Insulation Endeavour Centre
Dense pack cellulose can seal walls from air infiltration while providing the density to limit convection, when installed properly. The University of Colorado School of Architecture and Planning did a study that compared two seemingly identical test structures, one insulated with cellulose and the other with fiberglass. This video expertly shows the process of dense packing exterior walls with cellulose insulation. It also demonstrates what happens when walls are "loose fil.
