If you are familiar with insulating a house with fiberglass you know that it is cheap but nasty stuff. Spray applied, loose fill (dry) or dense pack (dry) cellulose as installed by Cellu-Spray is a far superior product. It will make for a tight, quiet, and most important ly, an energy efficient house. You can rest assured that you won’t be fielding calls about frozen pipes, mice, mold, or cold rooms if you choose Cellu-Spray to insulate your project.

Testimonial:

The energy efficency is great. What surprised me was how the sound attenuation made the house feel so solid. Prospective buyers walk and and they can feel the difference!
-Peter Starbuck, builder

By building a tight, energy efficient shell you can reduce the size of the heating and cooling equipment and use those savings to pay for the additional upfront costs of a better product.

New Construction
There are basically two ways that we insulate with new construction, spray applied or damp spray cellulose or dense pack or dry cellulose.

Spray applied
Spray applied cellulose or “damp spray” is installed with water added at the tip of the hose. We use high pressure hoses and the water is added in extremely fine drops as a powerful mist. This action combined with the relaxed cellulose fibers means that when the cellulose slams into the sheathing it builds up on itself, filling the entire stud bay. We spray the cellulose past the studs and they are then scrubbed down with a mechanical scrubber. There is no chance for any gaps or settling to occur. We use the minimum amount of water to get it to stay in the bays and easily achieve a density sufficient to cause the material to act as a good air barrier. The finished walls are then covered with sheetrock. We do not recommend a vapor barrier be added to side walls since it is an unnecessary expense. 98% of vapor in wall assemblies is due to air flow and since there is effectively no air flow through a wall insulated with cellulose, you can skip the vapor barrier necessary with fiberglass.

Drying time
Generally we prefer to have at least 2-3 days between blowing in the cellulose and having the drywall hung. If you can wait a week, even better. When weather is very damp, you would want ore than two days. Setting up fans which keep the air moving can help speed the process.

Dense Pack
Cellulose insulation can also be dense packed behind insulweb fabric which is stappled to the existing 2X's. This should be dense enough that once installed the netting could be removed and the insulation would stay in place, even with vibration. This is sense enough to satisfy legal fire stopping in residencial building code and too dense for a mouse to breath.

Retrofits
Once a layer of claboard hve been removed we come in, drill holes, and install our cellulose under pressure to ensure completely filled bays.
