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.


 


 






Environmental Insulation

When choosing an insulation product, it is important to consider not only the impact of insulation on utility bills, but also its impact on the environment. It is true that all insulation products will help reduce a home’s energy consumption, but this does not necessarily make all insulation products “green.”

Mineral fiber insulations, such as fiberglass, require tremendous amounts of energy during the manufacturing process. Furthermore, fiberglass insulation contains no more than 40% recycled content. Foam insulation products have very little or no recycled content and also use a great deal of energy during manufacture.

By comparison, Fiberlite’s Cellulose Insulation contains 82% post-consumer recycled paper and takes very little energy to produce. Insulating just one 1,500 square foot home with Cellulose Insulation recycles as much newspaper as an individual will consume in 40 years!

These facts, combined with the energy saving of a Cellulose insulated home, prove that Cellulose Insulation is truly the Greenest of the Green.

Comments
Cellulose Loose-fill, wall-spray (damp), dense pack, stabilized 3.6-4.0
(21-26)
Old Newspapers, telephone directories, borates Negligible Fibers and chemicals can be irritants High Recycled content and very low embodied energy
Fiberglass Batts, Loose-fill, semi-rigid board 3.0-4.0
(15-28)
Silica sand, limestone, boron, recycled glass, PF resin or acrylic resin, ammonia Formaldehyde emissions and high energy use during manufacture Fibers can be irritants High embodied energy
Mineral Wool Loose-fill, batts, semi-rigid or rigid board 2.8-3.7
(19-26)
Iron-ore blast furnace slag, natural rock, PF binder Formaldehyde emissions and high energy use during manufacture Fibers can be irritants High Embodied Energy; Rigid board can be an excellent foundation drainage and insulator
Cotton Batts 3.0-3.7
(21-26)
Cotton and polyester mill scraps (especially denim) Negligible Considered safe Two producers so transportation pollution is higher than other insulation
Closed-cell spray polyurethane foams Spray-in cavity-fill or spray-on roofing 5.8-6.8
(40-47)
Fossil Fuels; HFC-24.5fa blowing agent; non-brominated flame retardant High energy use during manufacture; global warming potential from HFC blowing agent Quite toxic during installation (respirators or supplied air required); allow several days of airing out prior to occupancy Very High embodied Energy
Open-cell, low-density polyurethane foam (Soy) Spray-in cavity-fill 3.6-3.8
(25-27)
Fossil Fuels and soybeans; water as blowing agent; non-brominated flame retardant High energy use during manufacture Quite toxic during installation (respirators or supplied air required); allow several days of airing out prior to occupancy Very High embodied energy
