KIMSUL* is unique among building in
sulations and acoustical materials be
cause it is made of many individual plies
--each one a continuous separate layer
of soft, clean, creped, asphalt-treated
cellulose fibers. Each ply is controlled
carefully in manufacture both as to thick-
g....-,^v, .
ness and crepe structure. The result is
a flexible blanket, inherently uniform in thickness--an important factor in a thermal
or sound insulating material. The Kimsul plies and cover of the creped Pvregard*
or creped Reflective Vaporseal are held together with rows of strong stitching that
prevent sifting and settling. No heat-leaking thin spots, no money-wasting thick
spots in the Kimsul blanket. Reduced to its installed volume for easier shipment,
handling and storage, the Kimsul blanket is expanded in installation. The stitching
controls expansion to the density of maximum efficiency.

Now Available--Reflective KIMSUL* Insulation
The text of these two pages applies to both Regular and Reflective Kimsul Insulation.
The differences in the two types are: Reflective Kimsul has a cover of aluminum foil
that acts both as a vapor barrier to shut out condensation, and as a highly efficient
reflective surface to turn back radiant heat. Reflective Kimsul has strong reflective
tacking flanges for easy, secure attachment to framing. For heat flow downward,
Reflective Kimsul provides additional insulating value. Regular Kimsul has the
Pyrogard fire-resistant cover.
Fire-Resistant--Special permanent chem
ical treatment makes Kimsul resist fire.
Pyrogard* Fire-Resistant Cover--(safety
feature of Regular Kimsul) resists flame-
spread.
Creped Aluminum Foil Cover--(a feature
of Reflective Kimsul) reflects heat, shuts
out condensation.
. *
Moisture-Resistant--asphalt treatment of
each ply sheds water.
Resists Mold, Rot, Vermin--The materials
of which Kimsul are made offer no subsis tence to vermin or insects. Special chem ical treatment resists mold and fungus.
Reflective KIMSUL JnetaUed. Edge of fastening flange folded
over face of framing completes the vapor seal.
"fc" Factor--0.27 Btu/sq ft/hr/F.
Air Space--is a prime requisite. Use a vapor-permeable building paper under ex
terior finish. Ventilation in attics and floors should never be omitted. Use approxi
mately one sq ft of louver area for 1000 sq ft of ceiling area.
SOUND CONTROL
Sound Deadening (one room to another).
Kimsul flexible blanket used in staggered
stud construction.
Lath and Platter
1) Absorbs sound from diaphragmatic action of wall panels.
2) Absorbs sound which leaks through joints, thus main
taining original sound resistance of partition.
3) Cushions wall surface.
4) Prevents accidental bridging.
Sound Absorption (within a room). The
blanket design makes Kimsul inexpen
sive as a sound absorbing element. See
