Blown in Cellulose Insulation in Upper Fairfield County


After a Mr. Handyman insulation retrofit, you'll never believe that so much was accomplished with so few disruptions. We staff our crew with two professionals: insulation specialist and skilled carpenter. They devise the most inconspicuous and easily-restorable areas for installation so that neither homeowners, nor their friends ever would know that a retrofit took place.

As Authorized Cel-Pak Installers, we are subject to ongoing inspections to assure our employees are using proper methods and techniques and our equipment is properly calibrated and maintained.

THE BEST FOR OUR FAMILY AND YOURSHands holding insulation

Mr. Handyman installs Cel-Pak Premium Cellulose Insulation because it is clean and green. What type of insulating material would you use to surround your family?

The contents of Cel-Pak are simple: recycled newsprint reduced to cellulose fiber (83%); the naturally-occurring mineral, borate (16%); and mineral oil (1%). Borate contributes to superior flame retardancy, mold deterrence, and insecticide properties within the insulation. Mineral oil suppresses dust and enhances the bond between the fire retardant and cellulose fibers. That's it!

Cel-Pak is green insulation: newsprint is recycled; only 750 BTU's are required to produce each pound; it's manufactured and delivered nearby within New England; and lower installation costs and 20%+ energy savings keep more "green" in your pocket.


Cel-Pak is not flammable, combustible, or explosive, and it presents no unusual hazard if involved in a fire. The dense fiber structure and fire retardants in Cel-Pak insulation slow the spread of fire through a building, giving occupants more time to escape and firefighters more time to save the structure. Cel-Pak, when exposed to fire, produces negligible amounts of smoke, which also helps to prevent the loss of life in a structural fire.

Cellulose insulation involves blowing fiberized newsprint into areas of a house at high pressure. Loose-fill installation blows the cellulose material onto the attic floor until a 10" to 18" blanket is established. For dense-pack installation, 2 1/2" circular holes are drilled into walls or floors, a tube is installed into the cavity, fiber material is blown into the enclosed cavity until it is filled, and holes are sealed and restored.

Both loose-fill and dense-pack applications achieve a high R-value (resistance to heat flow), which is approximately R-3.8 per inch. In addition to their excellent insulating values, they also reduce air infiltration into your living space.

At the following building components, installing cellulose insulation will improve energy efficiency and comfort:

Attic floor (loose fill)Attic space

EPA Energy Star recommends at least R-49, approximately 13" of loose-fill cellulose, at the attic floor of homes in Connecticut. Attic insulation levels greater than R-49 will further re-enforce the thermal barrier between your living space and the attic.

Heat loss and wasted energy (and money) occur when heated air escapes the living space and enters the attic. Air sealing all penetrations and framing intersections at the attic floor and installing sealed covers over house fans, bath fans, recessed lighting cans, and attic stairs will effectively eliminate the waste.

Floored attic areas (dense-pack)

Joist spaces underneath attic floor boards often are overlooked and under-insulated. Heat from your living space will find areas of least resistance to escape. Conversely, attic heat will exploit the same areas to permeate your living space during Summers. Continuous and consistent R-value across the ceiling thermal barrier will reduce heat flow through weaker areas.

Vaulted and cathedral ceilings (dense-pack)

Insulated attic space

An improperly-insulated vaulted or cathedral ceiling presents a few problems: 1) the roof deck overheats the living space in Summer -- increasing cooling costs, and 2) during Winter, heat from the living space warms the roof deck and causes ice damming.

If you're planning new construction or remodeling, these problems can be avoided. First, apply High-R insulation board to the underside of the roof framing. Blow high-density cellulose between the insulation board and the roof deck, and install sheetrock onto the insulation board. You'll achieve R-30 or greater, be comfortable, and save money.

Exterior walls (dense-pack)

Most walls are constructed with 2" x 4" studs, which provide 3.5 inches of space between the exterior sheathing (plywood) and interior sheetrock. Some older homes have very little or no insulation within these spaces. When fiberglass insulation has been used, the fluffy, cotton-like material permits air to flow through the cavity and degrade the fiberglass' R-value. Dense-pack cellulose maintains its R-value by limiting air flow through the wall cavity.

For new construction, additions, and remodeling, homeowners can enjoy the insulating, air sealing, noise reducing, and energy saving benefits of dense-pack cellulose. [An enclosed cavity is created by stapling a strong plastic sheet to the studs.]

Rim joists & band joists (dense-pack)Insulation installation diagram

Few homes -- old or new -- have properly air sealed joists at the beam ends. Air penetrates siding and infiltrates interior floor joists and wall studs. This phenomenon chills walls and floors and causes "cold rooms." Blowing dense-pack cellulose to fill the joist cavity -- just at the beam end -- will dramatically reduce air infiltration into floors and walls.

Floor joists at garage ceiling (dense pack)

A few factors cause cold bonus rooms: 1) air infiltration into the garage either when the door opens, or by random leakage and 2) insufficient insulation at the garage ceiling. If garage walls are insulated, extreme temperatures are trapped in the garage. Installing cellulose into the ceiling joists will help, as well as air-sealing the garage perimeter. Best results have been achieved when Energy Star qualified gas or electric heaters -- set to just 55 degrees Fahrenheit -- were installed at the garage ceiling.

Floor joists at crawlspace ceiling (dense pack)Handyman in crawlspace

If air flows through insulation, its R-value (insulating effectiveness) is compromised. A barrier of dense-pack cellulose will keep your living space separated from the cold crawlspace.

Noise reduction: floor joists within living space (dense-pack)

Cellulose insulation completely fills the cavities where it is applied, unlike most insulations. This means that cellulose not only prevents the movement of air and heat through your home, it does a better job stopping the transmission of sound.
