CORK ...
Its History
In iSic land contiguous to she \Ye>!ent Mediterranean and comprising parts of
i'ortngaj and iiuroccv, grows jn cvoigu.cn known a* the Cork Oak
fvu,vW Sitbfrj, This tree must survive a tremendous amount of heat since it
grows m tropical and semi-tropical acne*. Nature has provided lor tins by pro*
moting a growth which covers the trunk and limbs o1 the tree and effectively
insulates it merce. At
again.'! the intense heat. This growsh (or bark) periodic intervals the trees nr* stripped of tfii
is the cork or com hark, which is then
l!
processed, hnhd ansi shipped so mauniacturing centers m Europe ami the United
States. Various manufacturing plants produce a multitudinous variety i
pvodwcM vTvcUtdwvj cork. vwsuViLvceu
Cork has been used lor many centuries. We find that it was fabricated by the
ancients into shoe soles, floats of bottle >topjr*. in the past fifty years the uses of cork have multiplied many times. This peculiar and versatile matersl is now employed in all of the manufacturing anil process industries. It has even in\a<i?d the field of decorative art, and it may truly he regarded as a necessary concomitant vi civilization.
WHY CORK IS AX IXSL'LATOR
As explained alvve, Nature provided a coveimg that would protect the Cork Oak from the attack oi tropica! heat. This is accomplished ty shaping a covering o? relatively even thick ness containing a multitude of minute air parties each her metically sealed one from the other. Each particle of entrapped air is so smalt that it will net permit the setting up o* air ent reats and in this way heat penetration is prevented. Further
more, due to its granular structure, while practically all other insuSating materials are of a fibrous nature and have a hig^ degree of capillarity,
Atshough primarily designed for use in the Saizigeration and Cold Storage Industries, Muodet "Joitssite" Cork Insulation has a wide range of applications, as text co the following pages, u iil make clear.
TIIE >IAMFACTi;nE OF COIKKBOAKtD
The cork bark used for insulation is first ground up into panicles or granules of front 1' to % in. in size. These arc filler! into moulds and hydraulically pressed to the required density. The moulds are then placed in an oven maintained at a relatkely high tempo since for a period of time dependent upon the thickness of insulation involved. The cork is kept under compression In the moulds throughout the baking
process. The heat liquefies the gum or rosin that is peculiar to.' 'A this type of batk. This gum thoroughly binds the granules geiher ant! hermetically scats one from she other, producing a solid slab of cork board (still 100% pure cork). The rough slab Is then subjected to a finishing process which cuts it to accurate sue and sands its surfaces, completing the rnanufac-' lure of commercial ecukboard insulation.
ESSENTIALS OF fiOOD 1XSI.XATIOX

Insulation
To Prevent Condensation
It is generally recognized tod y
correct building
design mubt jodude insulatton. 'the heat transmitted iron) uninsulated texits in the winter results in a need
less loss, the cost of which comes io a staggering total.
Furthermore, the annoying and frequently expensive
problem of ceiling condensation may be easily overcome. In4he summer, these same roofsrab$orb a tremendous
.amount of heat and deliver it to the rooms below, thus
causing discomfort to, and impairing the efficiency of.
people who are working in these areas. In certain com
mercial plants where the'humidity and often the. tem perature must be governed 3t a high point, due to the
processes of manufacture, an uninsulated roof will in
evitably chiIt the air tn its vicinity* during the winter months to the point where some of its moisture con
denses and forms what is commonly known as ceiling "''`sweat." The moisture drops to the floor, producing a
most annoying condition to people who are working in
the room and often causing damage to property, since it will drop upon any materials and machinery that may
be underneath, The loss due to condensation must be
considered separately from the direct loss due to heat leakage through the joof, the latter being present in all
uninsulated construction while the former appears only
when the humidity is relatively high or when the dif ference in `iempeiaiuK between the inside of the root end the room is oT considerable magnitude,
Numerous industries are in the position of, for ex
ample. textile mirls, which have, as one of the pre
requisite.* ior proper manufacturing, a high degree of relative humidity. Many textile mills are located in
New England, and in winter are operating with a great
variation between the inside and outside temperature* of their buildings. Unless these buildings arc insulated, tlic walls and roofs become very much colder, on the
inside, than the surrounding air. This cold is trans
mitted to tlic adjacent air, which reaches the point of
total saturation (dewpoint), and deposits its moisture ujn the cold surfaces, from which come the drip. Thc
rtsuhant losses may be grouped as follows:

Unfortunately, tt is only recently that industry has
begun to subject its inherited losses to a careful scrutiny.
In the past, celling condensation was regarded as a
^necessary evil, and an inevitable concomitant. oLbi^h--... relative humidity. Advanced engineering practice m
new buildings, however, his dtmonswaWd ;u worth to
the point where manufacturers Have begun to realize
jJwt their old equipment cannot compete with new equip- '
men? unless it is brought up to date. However, the
tendency to maintain a given status quo, plus the mhibi- ;
rion against spending money upon old equipment, has *
produced a wnsidetabit ynicnws. It Vs tor this reason
that all roofs are not insulated, although there have been instances without number where cork insulation
has been installed in an existing plant and has paid for
itself within a few years in the single item of coal
required for heating, \Vhcn btingvog to the mention oi manufacturers the
need for cork insulation in buildings, the greater stress
has been laid upon the resultant saving in fuel. Today,
however, industrial executives In ever increasing num bers arc realizing that a most important factor in their
problem of keeping costs at a minimum is the attitude
os vhesr labor, A worker is never efficient when he is uncomfortable, end ihi:ret7rc_ifre -use m insulation,
while It mav be considered as an intangible benefit from
this Anglo, is n?veMill'less of vital Import.
Tlie other factor* that go to make up the losses in
uninsulated construction depend cntirelv upon individual
conditiona, anti i? U difficult to evaluate them in genera)
senns. btit it is reasonable to conclude that limy are
present In all ea*cs to a greater or less degree and must
eventually appear in the costs of manufacture.

Thickness of Corlilioard Xccded
U has already been shown that cork is the ideal insu
lation for this work. The next important thing to
determine is the thickness of corjcboard that must be
usoj.
.
There is no rule of thumb by which i? is possible to _ determine what thickness of cork insulation is required for any given roof. The thickness of insulation is an exnct function of the humidity present, the nature of-- the wall or roof constructlot), Its own co-efficient of heat transmission, and the maximum temperature dif ference on the two sides of the building* construction. In order to facilitate the determination of the correct
thickness of corkboard insulation for roofs, a special chars has been Included in this section (see page 17) upon which it is possible to read directly the permissible heat loss for any given set of conditions. Upon page 16 will be found a table showing the heat loss ot all com
mon types of roof construction. Under each type is shown the heat loss of that construction with various thicknesses of "Jomtitc" Corkboard Insulation. Typical cases are also shown graphically in illustrations on
page U.
The easiest way of demonstrating the use of the chart, table and illustrations will be to show the working <{ an actual case. Following is a typical problem: A
nnuiactufing plan? is equipped with a 3-in. yellow pine and standard %-in. built-up roofing. The inside
temperature (dry bulb) at the ceiling is 70s F,( the relative humidity is S0%, and the lowest temperature during the winter is minus 10s F.
Locate the line of 70 upon the room temperature scale at the top of the chart and follow down to the &0U relative humidity diagonal. Follow horizontally across the chart to the line of SO6 maximum temperature difference on the lower sc..'c. Interpolation between the bounding heat loss diagonal lines will show the heat loss to be .124. Referring to the heat transmission table, w? find that tn connection with a 3'in, yellow pine roof and s/$-h\. built-up roofing. \\<% in. of Mmidct ''jointite" Corkboard will give sufficient mstdalinn tn preclude the possibility of eom!ciisali<u for the alvive set of conditions.

Vibration Isolation
Among ihe multitudinous uses to which cork hns been applied, the one which is expanding most rapidly at the present limp is the utilization of its peculiar physical characteristics in the elimination of machine vibration.
The principal characteristics of a medium for machin ery isolation in the order of their importance, are:
(1) Ability to support the loads imposed upon it with out too great, or too varioblt, a deflection.
(2) Ability to absorb vibration in the machine with out transmitting it to liw surrounding structure.
(3) Permanence, including ability to withstand re peated loading without fatigue or permanent svt, ability to withstand the action of water, oil, acids or alkalis without deterioration, ability to maintain its resilience with age.
Of the many materials that have been used for illation purposes at one time or another, cork has proved itself to t*e pre-cmim-ntlv fitted for this work*. It contains over 50$- air by volume, and is made up of a myriad of tiny
tells, hermetically sealed trmn each other by the struc ture of the wood, fis onmjm^snn furies, rh.-rv/Vire. re semble muv uvarlv dun** *(' a gn* ihnn of ;m vin-viic solid, as is evident on page |0. This feature is important, be-
cause the resistance to loads, instead of being proportional to the amount of deflection, is proportional to the com
pression in the air tills: hence, under vibratory variations in loading, the active deflection is much smaller than for :m elastic substance, while t?e cushioning effect is higher,
Cork isolation has proven Uschl under the pragmatic test of use, and many thousands of installations, some of
them over a quarter of a century old, are giving complete satisfaction j often making possible the use of machine?
which without it could not U* usci| in their present loca tions because of the vibration] accompanying their
operation.

Type of Cork Isolation to Use
Mundet* Cork Isolation is made in |wo general types to
conform with the class of loadings imposed upon it. They
are as follows:
i
(1) Murjdet Natural Cork Isolation Mat--This form
of cork isolation is suited to loads of about SQQ to 20001b,
per sq. ft., normally encountered in machinery founda tions. 'Slocks ol natural cork ol the required thickness are
held within a rigid steel frame or are bound with asphalt paper applied in hot asphalt to the top and bottom sides of ilae_strips. The plates when laid together form a continu ous mat isolation of the exact size necessary. For isolating a machine in a pit with an envelope of cork, as shown in the illustration herewith, it is customary1, to use asphalt paper bound natural cork isolation mat. Where the ma chine is mounted on a floor slab without side Isolation, it is customary to use steel bound natural cork isolation mat.
In the case of average machine vibrations l1/* E0 2 in, of natural cork is adequate, but for more intense vibra tions or shock* loads, the thickness should be increased to 3 or 4 an.
(2) Mundet Machinery Isolation Cork-/Fhis is the material first used as isofefion cork and, whale ct has been superseded by the above material for light and medium loads, ior loads above 2000 lb, per sq. ft., Mundet Ma chinery Isolation Cork has not been surpassed. This eork is made in sheets, of various thicknesses, and in three densities, namelv, light, medium and heavy.
For loadings of 2000 to 3000 lb. per sq. ft., it is cus tomary to use either light or medium density, according to the character of the vibration. Light density is used for light vibrations and medium density for heavy vibra tions. From 3000 to 3500 lb. per sq. ft., either medium
density or heavy density is used, according to the char acter of the vibratorv load, and from 3500 to 6000 lb. j>cr sq. ft,. It is customary to use heavy density. The ihicknrbsvs of machmvry isolation c<rk used depend upon fin- iKXfvency atttl amj/Hnitk m the vibratioi? present, but the most common thicknesses .|mplove$ .are l5,i, 2,
3 and 4 in.
