Denim Insulation Versus Fiberglass Insulation: R-Value
Builders have been stuffing homes and businesses withfiberglass insulationfor long time because it ’s evenhandedly easy to fabricate and work well . It comprise of a fine matrix of flexible shabu fibers that create thousands of microscopic cell . These bantam pockets trap air and keep it from circulating , which reduces convection and heat carry-over . However , the small meth fibre can amaze into the skin and cause annoyance . They can also get into the eyes and into the lungs if inhaled . Some reports , such as the 1994 Annual Report on Carcinogens , have labeled fibreglass as " perchance carcinogenic , " prompting manufacturers to apply related to word of advice to their product .
Denim insulation carries no such warnings . It does n’t cause itching or irritation and can be installed without glove , safety goggles or a dust mask ( although DIY type and professionals may still need to tire a masquerade party while cut the batten ) . And it ’s safe for the long haul . Unlike some materials that off - throttle toxic vapors or fickle organic compound as they sit in your home , denim insulation sits inertly in your walls and floor , blocking the flow of heat without free harmful chemicals or irritants .
But does it work ? Does it actually compete with the pink fiberglass made famous by the cartoon Panthera onca of the same color ? Let ’s do a head - to - foreland comparison of the three most important functional attributes of construction insulation – gas constant - note value , acoustic performance andfireresistance .
universal gas constant - valuemeasures an insularism ’s resistance to estrus flow rate . If a material has a gamey radius - value , it has a neat insulating effect . fibreglass cream with a thickness of 3.5 column inch ( 8.9 centimeters ) delivers an R - value of 10.90 [ source : Nave ] . Increase the thickness to 6 inches ( 15 cm ) , and the gas constant - note value of fiberglass soars to 18.80 [ source : Nave ] . The same thickness of denim insulation deliver radius - values of 13 and 21 , respectively [ beginning : Bonded Logic ] . Score one for denim .
See how denim insulation fare on acoustics and fervour resistance next .
