Insulation
Conventional insulation materials such as fiberglass can be detrimental to your family’s health because they contain the toxin formaldehyde.
Formaldehyde is reasonably anticipated to be a human carcinogen, according to “The Report on Carcinogens,” tenth edition, U.S. Department of Health and Human Services, Public Health Service, National Toxicology Program. The toxin is suspected of causing a variety of illnesses, including cancer; illnesses of the respiratory tract; developmental, reproductive and skin disorders; and problems of the nervous system, according to the U.S. Environmental Protection Agency (EPA).
There are many other options for insulation that are safe and effective, including:
Cotton is free of formaldehyde, and can be recycled or turned into compost. It is also far less energy intensive to manufacture than fiberglass.
Bonded Logic makes natural cotton fiber insulation made from recycled denim and natural blend cellulose insulation.
Cellulose is made of wood fiber from recycled newspaper and other types of paper. Similar to cotton, it is energy-efficient to produce. It is important to note that inks from newsprint contain toxins. No inks are completely non-toxic, but you can minimize your risk of exposure by requesting materials that are derived form newspaper that was printed with vegetable- or soy-based dyes. Also, since toxic emissions usually become airborne through the dust that permeates the air during installation, you can request that cellulose be applied while it is wet. Dampening the material hinders the ability of the loose particles to become airborne. Also, choose a product that is treated with boric acid as a fire retardant. Source:

Straw bale is an excellent alternative to traditional insulation materials because it is undesirable to insects and flame-retardant when installed properly. Incinerating straw is a common practice, so reusing it as insulation is a great way to utilize a wasted resource and avoid air pollution created during the burning process. Since the material is particularly sensitive to moisture damage, it works best in dry areas with low humidity. Ask your contractor if straw bale is a reasonable option for your climate.
Please note that all insulations work best at low moisture levels.
