Insulation categories page: 1 of 1
Cementitious Foam (0 listings)
Cementitious foam, a frothy non-toxic mineral spray made of air, water and cement, provides excellent insulation, and was used in The Audubon Society's New York headquarters.
Cotton Fiber (1 listings)
Made from denim, the batted material is treated with borate to give it fire-retardant and mold-resistant qualities. It contains no harmful off-gasses and 85 percent recycled content.
Mineral Wool (0 listings)
"Mineral wool" actually refers to two different materials: slag wool and rock wool. Slag wool is an industrial waste product produced from iron ore blast furnace slag. Rock wool is produced from natural rocks of basalt and diabase. Slag wool accounts for approximately 80 percent of the mineral wool insulation industry and contains 70-90 percent post-industrial recycled content. It is available as blow-on wall insulation (a starch binder is used), as loose blow-in attic insulation, and as batts. It offers very good energy performance, will not burn, and is chemically inert.

Paper Fiber (1 listings)
Insulation made from recycled paper.
Spray Foam (6 listings)
Spray foam insulation is applied as a liquid which contains a polymer (such as polyurethane or modified urethane) and a foaming agent. The liquid is sprayed through a nozzle into wall, ceiling, and floor cavities where it expands to fill every nook and cranny. Because it expands into tight areas, sprayed foam is ideal for insulating steel framing and around outlets. Sprayed foam insulation does not shrink, sag, settle, or biodegrade. Spray foam insulations that are currently available can be divided into two categories, those that use HCFCs, and those that do not. Polyisocyanurate and polyurethane foams both use HCFCs as a blowing agent. Polyicynene and Tripolymer are both spray-on insulations made of proprietary substances that do not use CFCs or HCFCs. (Note: It is recommended that spray foam insulations be installed by a trained professional contractor.)
Structural Insulated Panel (2 listings)
Structural Insulated Panels or SIPs consist of two layers of wood sheathing laminated to a foam core. Some SIPs come with other facing materials: metal, drywall, fiberboard, even plastic. When installed in a home, the SIP provides both structure and insulation.
Cellulose (2 listings)
Cellulose is made from approximately 80 percent post-consumer recycled newspaper and treated with fire retardants and insect protection. Cellulose insulation that is treated with borates is preferred. Recycled newsprint that contains printer's inks can possibly outgas formaldehyde into a home. Insulation made from non-inked paper is available to eliminate any outgassing from inks. Cellulose can also be bound as a wet spray and installed by a professional in open wall cavities resulting in entire walls that are effectively sealed. A long-term performance concern is possible loss of fire-retardant chemicals.
