CeloteX 
Insulating Lumber 

CeloteX insulating lumber is made from cane fibre, or bagasse 
as it is called in the South. 

During the course of manufacture, the cane fibre is firmly inter- 
laced and felted into a strong, rigid insulating board. The strength 
of CeloteX is derived solely from its structure, and not from any 
adhesive. 

When CeloteX leaves the plant for the great field of building 
construction, it has been sawed into boards 4' wide, in lengths 
of from 8' to 12'. Its thickness is approximately xV'? while it weighs 
but 60 lbs. per hundred square feet. Hence, it is easily handled and 
installed, at a very low cost. 

CeloteX in many situations is a replacement for board lumber, 
at the same time providing exceptionally high insulation. In this 
double service, it makes insulation available to an extent heretofore 
prohibited by the cost of other insulating materials. Board-form 
insulation has been found to be the most convenient and practical to 
apply. CeloteX is the most durable and efficient — strongest and 
lightest board-form insulation. 

Formerly insulation, though considered desirable by the general 
building trade, has not been considered to be within the financial reach 
of the average builder or owner. During the last few years however, 
the value of insulation has become generally recognized, and the 
advent of CeloteX makes insulation available, with practically no 
increase in cost of the building. This is true because CeloteX takes 
the place of at least one other material, and sometimes more than one. 

Temperature insulation in general building construction has been 
more fully developed along the northern border of the United States, 
in Canada, and in other cold climates. In buildings where CeloteX 
is used, fully one-third less fuel has been consumed for heating pur- 
poses. CeloteX is adapted for keeping out the heat of summer, as 
well as the cold of winter. It finds just as great use in warm 
climates as in cold.

CeloteX was used as an outside sheathing, 
replacing lumber. Ribbed metal lath was 
nailed over CeloteX, and stucco applied 
to the surface.

USES 

Sheathing 

For the inside or outside of buildings, CeloteX can be applied 
like lumber, directly to the studding. Tests show that when applied 
as a sheathing, CeloteX produces a more rigid structure than ordinary 
wood sheathing. CeloteX is treated to resist the absorption of water. 
CeloteX, being a combined insulation and sheathing, gives the advan- 
tages of both, eliminating the cost of one. 

Exterior Finish 

CeloteX is admirably adapted for the exterior finish of a 
building. It is applied directly to the studs and serves as sheathing 
and the exterior surface. Batten strips are applied to form suitable 
paneling. CeloteX can be painted any color desired. 

Plaster Base 

CeloteX as a plaster base on partitions, walls, and ceilings, will 
conserve more heat than an ordinary wall of lath and plaster. It is 
especially adapted to this use because of its fibrous surface strength, 
and insulating value. All standard interior plasters form a perfect 
bond with CeloteX, CeloteX makes better and stronger walls; 
insures against leakage around openings. 

Roof Insulation 

CeloteX resists the passage of heat and cold like a heavy woolen 
blanket, and is most durable and efficient, strongest and lightest 
board-form of insulation. It lies flat on the roof without warping, 
and is not easily injured in working over it, CeloteX is water- 
resisting — a big factor in roof insulation. CeloTeX is mopped onto 
the concrete, or nailed directly to the wood deck in as many thick- 
nesses as are necessar)^, and any standard roofing is then mopped 
directly onto it. (See specifications.) CeloteX reduces fuel con- 
sumption in winter, keeps off the heat in summer, and protects against 
condensation.

Architects, Horace Colby Ingram, Asso- 
ciate Architect. Celotex was used in this 
beautiful building as a sound deadener. 
Insert at upper right shows in detail the 
method of application. 



Interior Finish 

CeloteX is used as an interior finish for walls and ceilings of 
homes, factories or stores. It is splendidly adapted for use where 
paneling is desired. Its color is a light, pleasing tan, suitable for the 
finish in many situations, or it can be stained or painted in any color 
desired. 




Sound Deadener 

CeloteX is effective as a sound deadener in floor construction 
and partitions. 




Chicago*s new five million dollar Municipal 
Pier, in which CeloteX was used for 
acoustical correction and interior finish. 



Acoustical Correction 

CeloteX absorbs about one-third of the sound waves which 
strike against it. This makes it efifective for eliminating echoes and 
reducing reverberation in auditoriums and school rooms; and in 
greatly reducing the noise in rooms where a large volume of sound 
is generated, such as school house corridors, restaurants, telegraph 
rooms and offices where adding machines, typewriters and other 
mechanical apparatus are used.

Tests 

Tests made by Robt. W, Hunt & Company, Engineers, Chi- 
cago, show the following results: 

Tefisile Strength: Tests made on three pieces of CeloteX, 
each 2 inches wide, showed an average tensile strength of 373 lbs. 
per square inch. 

Transverse Strength: A test on CeloteX board 6 inches wide, 
with supports 12 inches apart, showed a deflection of 11/16 inch 
under a load of 32 lbs. A test on CeloteX board 12 inches wide, 
with supports 16 inches apart, showed a deflection of 13/16 inch under 
a load of 158 lbs. 

Stiffness in Wall Sections: Tested as a sheathing material 
applied to studs, in comparison with sheathing of ^ inch x 6 inch 
(yellow pine boards), CeloteX showed six times as much resistance 
at the point of initial deflection, and nearly twice as much load at the 
point of failure. 

Plaster Bond: Six tests were made to determine the plaster bond, 
using CeloteX board 6 inches x 6 inches coated with wood fibre 
plaster to a thickness of J4 inch; the average breaking load was 216 
lbs. per test, which equals 864 lbs. per square foot of surface. 

Insulation: Standard Heat Transmission tests by G. F. Geb- 
hardt, Mechanical Engineer of the Armour Institute of Technology, 
Chicago. The flat plate method was used. It gives surface to sur- 
face conductivity and the results are indicative of the true insulat- 
ing quality of the material:

SPECIFICATION No. 6 

For the use of 

CELOTEX 
AS ROOF INSULATION 

Applied on the under side of Wood Rafters 

Note: This form of application is suitable for insulating existing 
roofs, and for new shingle roofs of wood, slate, zinc, copper 
and other types of roof covering materials, which require a solid 
wood deck for nailing. 

Material: Roof Insulation shall be CeloteX Insulating Lumber, 
approximately yV thick, as manufactured by The 
CeloteX Company, Chicago. 

Framing: The rafters shall be spaced 16'' on centers. Whenever 
it is necessary to have a horizontal joint in the CeloteX, 
a 2''x2'' or 2''x4'' header shall be cut in between the rafters. 
Rafters may be spaced 24'' on centers when considered desirable, 
but when so spaced, 2"x2" or 2"x4" headers shall be cut in 
between all rafters, on not to exceed 36" centers. 

Application: The CeloteX boards shall be applied lengthwise of, 
and directly to the rafters, and set in place so as to 
have a bearing for nailing along all edges. 

Leave 3^" space between adjoining boards, also at top and bot- 
tom of boards. Around openings and at corners or where a snug 
joint is desired, the CeloteX shall be fitted carefully and brought 
to moderate contact. DO NOT force i?ito place. 

Nailing: Nail the CeloteX to intermediate rafters and headers; 
then entirely around all edges of each board to rafters and 
headers. Use standard lj4" roofing nails with ^" heads, space 
nails 4" apart, driving nails until heads are flush with the sur- 
face of the CeloteX. Nails shall be placed approximately •>^" 
from the edge of the boards. 

Plaster Base: The above specifications provide for the application 

of CeloteX roof insulation to be used as a plaster 

base. See Specification No. 10 for applying plaster.

frame house construction, taking precaution, however, 
to space the studs 16'' on center. Any odd space required to make 
the over-all length should be located at one end, or near the 
middle. Wherever it is necessary to have a horizontal joint in 
the CeloteX, a 2^x2'' or 2''x4'' header shall be cut in between 
the studs. No special framing or bracing is necessary other than 
is usual in frame construction. 

Application: The CeloteX boards shall be applied vertically, 
directly to the wood frame work, without the use 
of wood sheathing, and set in place so as to have a bearing for 
nailing along all edges. When necessary to use more than one 
course of CeloteX to cover the height of building, vertical joints 
shall not meet on the same stud. 

Leave fV space between adjoining boards, also at top and bot- 
tom of boards. Around window and door frames, or where a 
snug joint is desired, the CeloteX shall be brought to moderate 
contact. DO iVOT force into place. 

When rafters project beyond face of studding, and roof insula- 
tion is laid according to 'Specification No. 7, CeloteX sheath- 
ing shall be cut to fit snugly around rafters, and to form close 
joint with the roof insulation. 

Nailing: Nail the CetoleX beginning at top, to intermediate studs; 
then entirely around all edges of each board to studs, sills, 
plates or headers. Use standard l}^'' roofing nails with ^'' 
heads. Space nails 4'' apart, driving nails until the heads are 
flush with the surface of the CeloteX. Nails shall be placed 
approximately ^'' from the edge of the boards. 

Side Walls: If wood siding is to be used, apply it directly over 
CeloteX, nailing through CeloteX to the studs. 
Siding boards shall butt over studs. 

Shingle Walls: If walls are to be shingled, shingle lath shall be 
applied over CeloteX and nailed through to 
studs, then the shingles shall be nailed to the shingle lath.

The above illustration shows the effective use of CeLOTEX nailed 
directly to the wood deck, and any standard prepared roofing mopped 
to the surface. Heat from the inside of the building cannot escape 
through the roof, and the result is a saving of at least 1/3 of fuel 
consumed for heating purposes. CeloteX in this construction pre- 
vents condensation which in many instances has been known to rot 
out wood decks and joists. (See SPECIFICATION No. 8. for 
applying.)

There is no better temperature insulator than CeloteX. It 
retains the heat on the inside of the building in winter and keeps it 
out in the summer — also prevents condensation. 

CeloteX will prevent extreme contraction and expansion in 
concrete slab construction. Expansion of unprotected concrete slabs 
has been known to force side walls out of plumb. (See SPEGIFI-

the CeloteX, a 2'^x2'' or 2''x4'^ header shall be cut in between 
the studs or joists. For ceilings, additional headers shall be cut 
in between the joists, not over 48'' on centers, or the joists shall be 
securely bridged. 

Application: For walls, CeloteX boards shall be applied vertically to 
the studs; for ceilings, CeloteX boards shall be applied 
lengthwise of the joists ; for both walls and ceilings, the boards 
shall be placed so as to have a bearing for nailing along all edges. 
Leave fV' space between adjoining boards, also at top and bottom 
of boards. Around window and door frames, sills and plates, or 
where a snug joint is desired, the CeloteX shall be brought to 
moderate contact. DO NOT force into place. 

Galvanized metal corner beads shall be used from floor to ceiling 
on all exposed corners. On all interior corners, both walls and 
ceilings, 6'' strips of No. 18 gauge standard wire lath, or No. 24 
gauge expanded metal lath may be used, if desired. They shall 
be nailed securely through CeloteX to the studs or joists. 

Nailing: Nail the CeloteX, beginning at top, to intermediate studs ; 
then entirely around all edges of each board to studs, sills, 
plates, headers or joists. Use standard 1>^'' roofing nails, with 
y^'' head. Space nails 4'^ apart, driving nails until the heads are 
flush with the surface of the CeloteX. Nails shall be placed 
approximately ^'^ from the edge of the boards. 

Note: DO NOT wet or dampen CeloTeX before applying plaster. 

The use of Gypsum or wood fibre plaster is recommended. 

Gypsum (Two-coat work.) If neat Gypsum plaster is mixed at the 
Plaster: building, use one part neat Gypsum plaster and two parts 
clean, coarse, sharp sand. If a standard brand of sand Gypsum 
plaster is used, it should be mixed according to manufacturer's 
directions. Apply plaster directly to CeloteX, in the same man- 
ner as applied to lath. The first coat must have a thickness of 
^'^ The finish coat shall be applied in the regular way. 

31 



Wood Fibre The plaster shall be an approved standard brand wood 
Plaster: fibre plaster, to be mixed and applied according to 

manufacturer's directions. The plaster must be applied to a 
thickness of %"'. Before plaster begins to ^^set," broom the sur- 
face, leaving it rough to take the finish coat. 

The finish coat may be a sand floated or white putty finish, applied 
in the usual manner. 

Note: Where irregularities occur in construction, due to uneven 
joists and studding, making it necessary to use additional 
plaster to straighten w^alls and ceilings, 3-coat work may be 
needed; first apply a light scratch coat, and when this coat is 
dry or has *^set," follow^ with a rodded brown coat to straighten — 
then finish in the usual manner. 

Ventilation: ( Important ) Cold and hot air or moisture will not pass 
through CeloteX. The plaster must dry by giving up 
its moisture to the air in the room. The room must be ventilated 
to carry away this moisture. It is absolutely necessar}'-, especially 
in winter, to give proper attention to ventilation while plaster 
is drying.

SPECIFICATION No. 12 

For the use of 

CELOTEX 

AS INTERIOR FINISH 

Material: Interior finish for all walls and ceilings shall be CeloteX 
Insulating Lumber, approximately 1%'' thick, as manu- 
factured by The CeloteX Company, Chicago. CeloteX 
boards shall be ordered of such lengths as will conform to the 
designs of paneling required. 

Framing: The studs and joists shall be framed as in ordinary con- 
struction, taking precaution, however, to space them 16'' 
centers. In laying out the studding and joists, consideration must 
be given to the design of paneling required, using extra studs 
and joists if necessary. Wherever it is necessary to have a hori- 
zontal joint in the CeloteX, a 2'' x T' or T x 4'' header shall be 
cut in between the studs or joists. For ceilings, additional headers 
shall be cut in between the joists, spaced not over 48'' on centers, 
or the joists shall be securely bridged. For the most substantial 
construction, headers shall also be provided back of chair rail 
and all other mouldings. 

Application: For walls, CeloteX boards shall be applied vertically 

to the studs; for ceilings, CeloteX boards shall be 

applied lengthwise of the joists; for both walls and ceilings, 

boards shall be placed so as to have a bearing for nailing along all 

edges. 

Leave 3^7-" space between adjoining boards, also at top and bot- 
tom of boards. Around window and door frames, or where a 
snug joint is desired, the CeloteX shall be brought to a moderate 
contact. DO NOT force into place. 

Nailing: Nail the CeloteX, beginning at top, to intermediate studs; 
then entirely around all edges of each board to all studs, 
joists or headers. Where nail heads are to be covered by panel 
strips or moulding, use standard Ij^" roofing nails, with ^" 
heads, spacing nails 4" centers and driving until heads are flush 
with the surface of CeloteX. On intermediate studs, joists or 
headers not covered by panel strips or moulding, use 1^" finish- 
ing nails. They shall be driven at an angle of 30 degrees. Drive 
the nails so that the heads will lie slightly below the surface of 
the CeloteX. To avoid marring the surface use a fine nail set. 

Panel Joints shall be covered with wood or metal mouldings, 

Moulding: or strips not less than 2" wide. 

Painting and The CeloteX may be left with its natural finish, or 

Decorating: it may be painted or decorated with paints, stains, or 
kalsomine. All painting or decorating shall be done 
before applying panel strips or mouldings. For painting, see 
Specification No. 14. 

Note: If CeloteX is used as an interior finish for the purpose of 
accoustical correction, it must not be painted, but it may be 
stained, provided no sizing is used. 

35 




CeJL-oteX As An iHTEitioR^ Finish. 

CeloteX combines insulation with a beautiful interior finish, in 
construction where plaster is not desired. CeloteX is conveni- 
ently and quickly applied, keeping labor cost at a minimum. 
Wood panel strips are necessary in this form of construction. 
CeloteX may be stained or painted, or left in its natural color, 
which is a light pleasing tan. Most wall boards and interior 
finishes transmit sound. CeloteX resists the transmission of 
sound. CeloteX interior finish will not only resist the passage of 
heat and cold, but in its natural color, or tinted, will harmonize 
with decoration and furnishings. 

(See SPECIFICATION No. 12 for applying CeloteX as 
an interior finish.)

CELOTEX 

FOR SOUND DEADENING IN BUILDINGS WITH 

WOOD JOISTS 

Material: Deadening shall be CeloteX Insulating Lumber, 
approximately jV' thick, as manufactured by The 
CeloteX Company, Chicago. 
Application: Apply CeloteX strips 2'' wide to floor joists, nailing 
only sufficiently to hold them in place. Sub-flooring 
shall be laid over this, and nailed through to the floor joists in the 
usual manner. A layer of CeloteX shall be placed over the sub- 
flooring. The CeloteX shall be laid lengthwise of floor joists, 
bringing edges of boards to moderate contact with each other 
and with walls. CeloteX shall be securely nailed to sub-floor- 
ing with common 6d. nails, driven so the heads are flush wnth 
the surface of CeloteX. 

Over the CeloteX apply V x 2'' wood strips 16'' on centers, nail- 
ing these strips through the CeloteX to the sub-floor sufficiently 
to hold them in place while applying finished floor. Apply fin- 
ished floor over this, nailing to the w^ood strips, using nails that 
will not project through the wood strips into the CeloteX. 
CeloteX shall be applied on all walls and ceilings, as specified 
for plaster base. (See Specification No, 10.) 
Alternate The above method of floor deadening is preferred. If 
No, 1: desired, sub-flooring may be laid directly on floor joists 
in the usual manner. CeloteX shall then be applied, 
nailing securely to sub-flooring. The finished floor may then be 
laid on the CeloteX, nailing through the CeloteX to the sub- 
flooring. 
Alternate Wood sub-flooring may be omitted at the discretion of 
No. 2: the architect. If omitted, CeloteX must not be applied 
until building is ready for finished flooring. Wherever 
it is necessary to have a horizontal joint in the CeloTEX, a 2'' x 4'' 
header shall be cut in between the floor joists. Similar headers 
shall be cut in between the joists, spaced not over 48^' on centers. 
Apply CeloteX lengthwise of the floor joists, bringing edges 
of boards to moderate contact wdth each other and with walls. 
Nail CeloteX- securely to floor joists and headers, using common 
6d. box nails, driving nails until the heads are flush with the 
surface of the CeloteX. Finished floor may then be laid directly 
over CeloteX, nailing through CeloteX to the floor joists.

SIZING. PAINTING, STAINING OR TINTING 


# 


CELOTEX 




Sizing: To secure maximum covering capacity, the surface of 




CeloteX should be sized, or primed. Standard sizes now 




on the market work well with CeloteX. For best results, the 




following methods are recommended : 




"A" Size: Dissolve two pounds of shell or chip glue in a gallon 




of boiling water and allow to cool. Apply size within 




eight hours of time of mixing. Apply in a heavy, uniform coat. 




If desired, a second coat may be applied within four to six hours, 




making use of the above size diluted with one-quarter volume of 




water. When glue size is dry, paint or stain may be applied. 




"B" Priming Mix 75% boiled linseed oil, 25% standard grade paint 




Coat: by volume. Apply rapidly, brush on lightly and allow 




to dry thoroughly. For the priming coat use the same 




color of paint as is to be used for the finish coat. 




Painting: Any standard grade paint may be applied to CeloteX, 




when sized as above. One coat gives sufficient protection, 




but to obtain a high gloss two coats are necessary. 




Staining: For staining use two coats of glue size, as above. Apply 




alcohol stains over this. Benzol stains work well, but do 




not give as good results as alcohol stains. When desired, white 




shellac or colorless varnish may be applied over the stain to pro- 




tect it, and give a high gloss; or the stain may be omitted and the 




CeloteX varnished or shellaced. 




Note: For acoustical correction CeloteX must not be painted, but ' 




but it may be stained, provided no size is used.

MAKE YOUR ROOF SHED HEAT AND COLD 



Insulate Your Attic and Stop Coal Waste 




YOUR attic — a 
m u s t y deposit 
for odds and 
ends or a livable room 
— which? There isn't 
much doubt which you 
would prefer. Trans- 
form waste space into 
a nursery or an extra 
bedroom, by lining 
the walls and ceilings 
with Celotex Insulat- 
ing Lumber — at the 
same time insulating 
the roof against heat 
and cold. 



Economy Celotex, particularly when 
used as a roof insulation, 
soon pays for itself by the material reduc- 
\tion in coal consumption, 

The fuel consumed in heating your house 
produces a definite number of heat units. 




These units ultimately 
escape to the outer 
air, principally 
through the roof. 

Line your attic with 
Celotex and stop use- 
less coal waste. Celo- 
tex replaces lumber 
and has the insulating 
value of cork. It is 
easily and convenient- 
ly handled and ap- 
plied, at a minimum 
labor cost. Celotex 
protects alike against 
winter cold and sum- 
mer heat. 



Convenience Celotex is extremely light 

in weight (approximately 

60 pounds per 100 square feet). Almost 
anyone can apply it. 

It is available in sizes suitable for any 
building purpose (dimensions 4' x 8' to 



THERE IS A USE FOR CELOTEX IN EVERY BUILDING

n 



12' X 7-16'' thick) and is sawed and handled 
like ordinary lumber. 

In addition to the advantages of insulation, 
Celotex also serves as an efficient sheathing, 
plaster base, exterior, interior finish and as 
a sound deadener ; the deadening of sound 
being particularly important should you con- 
vert the attic into a children's play-room. 

Celotex provides a beautiful natural finish, 
or if you prefer, it can be stained, painted 
or tinted. It also serves as an efficient 
plaster base. Throughout your house and 
garage you will find many other uses for 
Celotex. It is proving itself a revolution- 
ary product in the building industry.
