Turning Waste Paper Into


Cellulose Insulation

Fiberlite recycles tons of waste paper daily, turning it into an amazing array of cellulose insulation products to improve the energy efficiency and comfort of homes and commercial buildings for the people who occupy them. Let us help you insulate to save money on your utility bills and make your home or workplace more quiet and comfortable.


 


 






Air Infiltration

Industry professionals understand that many factors beyond R-Value must be considered when insulating homes and buildings. Air infiltration is just as important as R-Value in the thermal performance of a building and the effectiveness of insulation. Infiltration of outside air means that heating and cooling systems must expend more energy to compensate for the infiltration. Cellulose Insulation impedes air flow, providing superior R-Value and minimizing air infiltration.

The higher the density of the material, the more effectively an insulation product impedes the movement of air. High-density cellulose insulation is extremely effective at inhibiting air movement. Lower-density insulations can be air permeable, allowing outside air to flow into the building through cracks, seams between building materials and through the insulation itself. Cellulose insulation seals houses better, limiting airflow not only through the insulating material, but also around difficult to insulate areas such as gaps around electrical boxes, wiring and plumbing.

Field tests have shown that blown in cellulose insulation can provide a building envelope seal that is 36% tighter than a fiberglass batt insulation seal.

To prove the point, a Canadian firm, Howell-Mayhew Engineering, conducted a test on a new cellulose-insulated home for air tightness. First the engineers measured its air leakage after a polyethylene air/vapor barrier and before siding were installed. The engineers then slit the polyethylene air/vapor barrier in approximately 20 places and retested air leakage of the building. There was absolutely no change in measured air leakage. Additional Smoke Pencil Testing at the slits showed "not a breath" of air leakage.
