Put in the batt, it's cheaper then blow some in to get into the areas that is'nt covered.
Batt is better if you can get it in everywhereBlown is ideal for those hard to reach spaces.
The machine to blow is usually free if you by the stuff from about anyone here in Ohio at leastIt is very very easy to doIt is just a big vacuum cleaner running in reverse so to speakDump the stuff in and shove the hose up in the atticyou aim it around or drag it a bit to fillI would not even consider batts.
Batt is simply compressed blown, and so the thermal insulation qualities are the sameI prefer batt because it is easy to handle, easy to lay even in those hard to reach areas, doesn't get up your nose so much, doing it yourself saves a lot of $'sNot only that but you have now learn't a new skill, and work type experienceYou have the convienience of inconvienience at your own convienience.
Acrylic is a manufactured fiberAcrylic is a soft drapeable fabric which provides warmth without being heavyIt takes color beautifullyAlthough acrylic has traditionally been a fall/winter fabric, with a wonderful resemblance to wool, acrylic has recently been used in developing some light weight circular knits and blends which lend themselves to trans-seasonal dressing as wellAcrylic is comfortable to wearIt feels like woolYet, it is easy care and is machine washable or dry cleanableProduction The polymer is formed by free-radical polymerization in aqueous suspensionThe fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide or aqueous sodium thiocyanate, metering it through a multi-hole spinnerette and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated inert gas (dry spinning)Washing, stretching, drying and crimping complete the processingAcrylic fibers are produced in a range of deniers, typically from 1 to 15 as cut staple or as a 500,000 to 1 million filament towEnd uses include sweaters, hats, hand-knitting yarns, rugs, awnings, boat covers, and upholstery; the fiber is also used as a precursor for carbon fiberProduction of acrylic fibers is centered in the Far East, declining in Europe and now shut down (except for precursor) in the U.SFormer U.Sbrands of acrylic were Acrilan (Monsanto), Creslan (American Cyanamid), and Orlon (DuPont) CHARACTERISTICS: Luxurious appearance Crisp or soft hand Wide range of colors; dyes and prints well Excellent drapeability and softness Shrink, moth, and mildew resistant Low moisture absorbency, relatively fast drying No pilling problem, little static problem Most acetate garments require dry-cleaning
