We had 30yr old pink (color is a MFG trademark, so there are other batt fiberglass products that are NOT pink). It was a zoological treasure trove, so IF you would like to provide fluffy bedding for furry and 6 or more legged critters, fiberglass batt insulation is an answer... we changed to an insulting reflective product that does not harbor infestations, mold or mildew (Reflectix was the tradename of the insulation product we used, but there are others) (to be fair, batt insulation would be fine & was fine in some of our SIP structure that had maintained perfectly sealed conditions, but if critters can enter, from our house, it seems they will)
Also always be aware that some insulations are NOT flametested and have tested many insulation products in my early engineering career, some can actually become flaming rivers streaming down if they have sufficient conditions for ignition....not something most would recommend to install in a house, but if utilized, you must be hyper-vigilant about those ignition conditions...
many houses here do not have insulation, for walls, direct sunlight (esp. early morning and late afternoon) can raise the wall temperatures enough to create hot to the touch interior walls (not combustible hot, just enough to have the effect of increasing the room temperature by degrees. Insulation can also buffer some exterior noise, but if windows are open, that is a mute point. Reflective barriers without insulation can also aid in reducing radiant heat from the sun, without buffering any noise.
