About Cellulose Insulation

The Burning Question

Technical Data

Today, as in the past, energy conservation is a vital concern for homeowners and the entire nation. RTek Insulation is proud to offer Advanced Fiber Technology's Cellulose Insulation as a combatant to high energy bills.

Why You Should Consider AFT Cellulose Insulation

Outperforms Fiberglass

AFT cellulose insulation is denser than fiberglass and when installed conforms to the space where it's installed - creating a seamless thermal and acoustical blanket that minimizes Air infiltration, increases Comfort and Energy Savings, is Environmentally Friendly, and has Superior Fire Performance.

Air Infiltration

Cellulose insulation has long been regarded as superior to other fiber insulation materials in sealing the building envelope against air infiltration. This characteristic was “conventional wisdom” until researchers at the University of Colorado put the concept to the test in identical structures in the winter of 1989 and 1990. The cellulose insulated structure was 36% tighter than the fiberglass insulated structure.

Comfort and Energy Savings

A tighter building envelope with better air infiltration properties achieved a 26% greater overall energy efficiency compared to fiberglass according to the same 1989-1990 study by the University of Colorado. This reduces maintenance costs on the heating/cooling system by less frequent operation and creates more consistent room-to-room temperatures. Heating and cooling systems can be downsized through the use of AFT Insulation. The higher density of AFT Insulation results in excellent sound-deadening properties to reduce outside and inside noise.

Environmentally Friendly

AFT Insulation uses 100% recycled wastepaper fibers. This reduces landfill space requirements, conserves trees, saves energy, and uses considerably less energy to produce compared to equivalent fiberglass insulation. No asbestos, formaldehyde, or fiberglass is contained in AFT Insulation.

Superior Fiber Performance

AFT Insulated is rated as a Class 1 building material when tested in accordance with ASTM E84. The fire retardants inhibit the spread of fire while fiberglass melts under the same conditions and creates open spaces for flame and smoke to travel. In 1995 the National Research Council of Canada's testing of cellulose insulated floor/ceiling structure had 50% higher fire resistance compared to similar fiberglass structure.

Retrofitting

AFT Insulation is an excellent choice for adding insulation to uninsulated walls by drilling holes into the wall cavity and blowing the fibers inside. Researchers at Oak Ridge National Laboratories found that capping loose-fill fiberglass with cellulose insulation not only adds R-value but restores the significant loss of fiberglass R-value performance under cold attic conditions due to air convection.

Problem: Air and Sound Infiltration

Solution: Cellulose Insulation "Dry" Spray

Cellulose Insulation

Cellulose vs Fiberglass Air infiltration is an enemy of heating and cooling fuel bills as it causes drafts, energy loss, and convectional airflow. "Dry" sprayed cellulose insulation uses the latest application techniques along with natural AFT fibers to effectively seal the wall cavity. "Dry" spray cellulose insulation totally fills the wall cavity regardless of the wall stud spacing. Off-center wall stud spacing of only 1/4 inch results in an uninsulated wall area of 24 square inches based upon conventional width fiberglass batts. In addition this eliminates the potential gaps from hand cutting fiberglass to fit non-standard wall cavities spaces.

Cellulose Blown Insulation Gaps can also exist around electrical boxes, wiring, plumbing, air ducts, etc. that are located in the wall. The seamless cellulose blanket reduces air infiltration resulting in increased comfort and reduced energy costs throughout the full year.

cellulose insulation scrubbed After dry spraying the cellulose insulation into the wall cavity, the excess fibers are scrubbed with a specially designed tool that creates a smooth surface for the drywall.

"In 1990, The University of Colorado-Denver compared sprayed cellulose and fiberglass batt insulation in identical structures during the winter heating season and found that cellulose insulation was 38% tighter and required 26% less energy."
