In the wintertime , affectionate air from the inside will move to the outside and make us cold . In the summertime , hot melodic phrase moves from the outside to the inside and makes it uncomfortably ardent .

We have heating andair conditioningsystems to mend these problems , but the more opportunity warm air has to flow out of or into the home , the harder those systems have to work .

Fiberglass insulation , a mankind - made mineral fiber con­structed from a mixed bag of stuff , such as sand and recycled glass fiber , is the most popular soma of insulation in the United States – more than 90 percent of homes in America are lined with the pink stuff [ source : Spencer and Gulick ] . But while many see the benefit of insulating our house with fiberglass , some are worried fibreglass can have various wellness problem – it ’s capable of do immediate skin irritation .

But while some enquiry suggests that breathe in fibreglass particles could induce malignant neoplastic disease , but in 2001 , the International Agency for Research on genus Cancer get rid of glass , tilt and scoria fleece fibers – common elements of fiberglass insularity – from its inclination of substances possibly carcinogenic to humans [ root : NTP , IARC ] .

Breathing in airborne fiberglass fibers can also increase the difficulty of breathing . Is that the extent of the trouble fibreglass can cause , or are there more serious wellness effects ?

Builders began to instal fiberglass insulation in the United States just as another insulating stuff –asbestos– was phased out of use . Asbestos , unlike fiberglass , is a naturally occurring silicate material determine in rock . Its known use go back to the ancient Greeks , who admire it for its heat electric resistance .

Indeed , asbestos is n’t just resistant to heat . It also does n’t evaporate in the breeze , disband in weewee or respond with most chemicals . All of these place made it particularly attractive forhome construction , and asbestos was the main detachment fabric used for building insulating material for the tardy 19th century and much of the 20th century .

But as early as the thirties , the wellness hazards of asbestos became clear . When asbestos fibre are released into the air , they split into microscopic spell . Once breathed in , asbestos fibers will be inhaled late into thelungs , where they quell for farsighted periods of time .

During that time , the fibre irritate lung tissue and any other part of the body they may travel to , disruptingcelldivision by intervene with chromosome distribution and changing authoritative genetic cloth . This increases the luck of spring up illnesses such as asbestosis , mesothelioma and othercancers , although symptom of any such disease typically wo n’t show up for 10 to 40 years .

Asbestos is classified as a known human carcinogen by state of matter , federal and international agencies , and new use of the material were censor in 1989 by theEnvironmental Protection Agency . Still , we oft see asbestos - bear on trouble , from the emptying of poorly constructed shoal buildings to debris created fromHurricaneKatrina in New Orleans in 2005 .

While asbestos is a innate textile and fibreglass is man - made , the two material are often compared because they ’re both fibrous . This quality made fiberglass a in effect substitute once the health personal effects of asbestos became seeming . It also has the heat - insubordinate qualities that made asbestos so worthy for insulation .

It also has some worried that the fibers from fibreglass are just as dangerous as asbestos – it ’s sometimes referred to negatively as " man - made asbestos " or the asbestos of the twentieth century . But while early research on rats in the 1970s tell that " stringy methamphetamine of small diam is a powerful carcinogen , " more modern research is n’t as sweeping in its finding [ source : Montague ] .

The American Conference of Governmental Industrial Hygienists , on the other hand , claims fiberglass is " Not distinctive as a Human Carcinogen , " mean there is n’t even information to say whether or not it get cancer in people [ source : Yeshiva University ] .

The U.S. National Toxicology Program issue its 13th Report on Carcinogens in fall of 2014 , and while its entrance on sealed Glass Wool Fibers ( Inhalable ) states that they are “ somewhat anticipated to be human carcinogens , ” it also goes on to say that there is so much sport in production that full assessments must be made on a pillowcase - by - case basis [ source : NTP ] .

photograph to fiberglass is generally view safe , especially when in good order instal . Still , those that project to deal it are encouraged to avoid peel contact by wearing protective gear like gloves and refuge goggles . Once it ’s put in , fiberglass rests safely between charge plate reenforcement panels , sheetrock and plaster – only when it ’s removed will fiber become airborne .
