CALL 1-800-679-9210 FOR A FREE QUOTE AND FIND OUT WHAT THE
C & D DIFFERENCE IS FOR YOURSELF.
WHILE WE BELIEVE THAT THE BEST VALUE FOR THE DOLLAR IS WITH EXTRUDED POLYSTYRENE INSULATED PANELS. FOR OUR CUSTOMERS WHO PREFER URETHANE INSULATED PANELS
WE NOW OFFER 4" AND 5" HIGH DENSITY RAIL FRAME CONSTRUCTION, FOAMED IN PLACE CLASS 1 URETHANE INSULATED PANELS.
IS YOUR HEAD SPINNING TRYING TO DECIDE BETWEEN EXTRUDED POLYSTYRENE OR URETHANE?
AT C & D EQUIPMENT YOU HAVE THE CHOICE.
High Density Rail:
In this type of panel, the frame is composed of high density (over 8lb per square ft) urethane "boards". The density of urethane used in the insulating portion of a urethane insulated panel is about 2.2 lbs per board foot.
In this type of panel you have the high structural strength of a wood framed panel, as compared to a frameless "foamed in place" urethane insulated panel without sacrificing the insulating value of the panel as with wood frame construction.
Another advantage is that High Density Rail panels are not subject to rot as wood framed panels are.
ARE YOU PLANNING ON STORING THE FOOR IN YOUR WALK IN COOLER OR WALK IN FREEZER AT 70 DEGREES FAHRENHEIT? NO?
WE DIDN'T THINK YOU WOULD. THAT IS WHY WE USE DOW BRAND, HIGH R XPS.
MOST INSULATING MATERIALS R-VALUES ARE COMMONLY REFERRED TO AT TEST TEMPERATURES USED IN THE HOME CONSTRUCTION INDUSTRY FOR INSULATING INTERIOR WALLS OF HOMES.
THIS FIGURE IS MIS-LEADING FOR A WALK-IN COOLER OR WALK IN FREEZER APPLICATION, BECAUSE OF COURSE WALK IN COOLER WALLS ARE USUALLY AT 35F, AND WALKIN FREEZER WALLS ARE AT 0F OR LOWER, NOT 70F LIKE THE INTERIOR OF A HOME.
BELOW IS THE THERMAL RESISTANCE PROFILE OF OUR HIGH R XPS INSULATION AT DIFFERENT TEMPERATURES.
AT 70F / R-5 PER INCH (4 INCH PANEL R-20)
AT 55F / R-7.2 PER INCH (4 INCH PANEL R-28.8)
AT 35F / R-7.7 PER INCH (4 INCH PANEL R-30.8)
AT 25F / R-8.1 PER INCH (4 INCH PANEL R-32.4)
UNLIKE URETHANE, OUR INSULATION PERFORMS BETTER AT TEMPERATURES USED IN THE REAL WORLD
FOR WALK-IN COOLER AND WALK IN FREEZER APPLICATIONS
Whole panel R-Values for our panels is R-32.4 (at 25F)
AND EVEN BETTER AT 0F)
(Unlike our competitors 3.5" wooden framed panels where R-29 only applies to the center of the panel AND THE FRAME IS ONLY R-5) (due to pressure from wood frame panel manufacturers the R-value of the wood framing was exempted from E.I.S.A. energy requirements)
ALL 4" OF OUR PANELS INSULATION FOR BOTH COOLERS AND FREEZERS IS HIGH R-VALUE XPS (HIGH R-VALUE EXTRUDED POLYTYRENE).
SOME OF OUR COMPETITORS THAT TOUT THEIR USE OF EXTRUDED POLYSTYRENE (XPS) USE ONLY 3" OF XPS AND 1" OF LOW DENSITY EXPANDED POLYSTYRENE (AS USED IN COFFEE CUPS) SANDWICHED TOGETHER FOR THEIR COOLERS, AND ONLY USE A SOLID 4" OF EXTRUDED POLYSTYRENE FOR THEIR FREEZER PANELS.
WITH C & D EQUIPMENT WE USE ONLY A SOLID 4" OF HIGH R XPS FOR BOTH OUR COOLER AND FREEZER PANELS!
THE ONLY THING "PREMIUM" ABOUT THE OTHER GUYS WALK IN COOLERS AND WALK IN FREEZERS IS THE PRICE YOU PAY.

WE FEATURE:
4" THICK DOW BRAND HIGH R (HIGH DENSITY) / XPS (high R-value extruded polystyrene) insulated panels with a natural embossed Acrylic coated Galvalume finish, (Galvalume 6 times more corrosion resistant than our competitors G 90 grade galvanized steel finish).
OUR COMPETITORS URETHANE INSULATION HAS A HIGHER (BETTER), THERMAL RESISTANCE (R-VALUE), AT HIGHER TEMPERATURES, AND A LOWER (WORSE), THERMAL RESISTANCE (R-VALUE), AS TEMPERATURES DECREASE. MAKING ITS PERFORMANCE IN WALK-IN COOLER AND FREEZER APPLICATIONS LESS EFFECTIVE.
DOW BRAND XPS INSULATION HAS A HIGHER (BETTER), THERMAL RESISTANCE, R-VALUE, AT LOWER TEMPERATURES, MAKING IT PERFECT FOR WALK IN COOLER OR FREEZER APPLICATIONS.
AT 35F (COOLER TEMPERTURE) THE R-VALUE IS R-30.8
AT 25F THE R-VALUE IS R-32.4. AND EVEN BETTER AT A MORE REALISTIC FREEZER TEST TEMPERATURE OF 0 DEGREES FAHRENHEIT
(OUR DOW BRAND HIGH R XPS INSULATIONS HIGH COMPRESSION STRENGTH, (USED IN INSULATING BUILDING SLABS), MEANS LESS FLOOR DEGRADATION SUCH AS SINKING, AS SEEN WITH URETHANE INSULATED FLOORS
THINGS TO CONSIDER ABOUT URETHANE INSULATED PANELS:
1. Their panels overall R-value, or K-factor.
(The wooden frame portion of a wooden framed panel has an R-
value that is much lower than the insulating material that is only in
the middle of the wooden frame.
Meaning that the panels overall R-value or K-factor is far lower than
the insulating material which is only in the center of the panel. In
other word they are leaving out the low R-value of the wooden
frame portion of the panel when making their R-value claim for the
panel)
They are telling you only their "foamed in place" urethane
panels initial R- value, not it's 6- month "aged R-value" after
"outgassing" has occured, or it's Long Term Thermal Resistance.
2. Stability of the R-value: When urethane is manufactured, the cell
gas is mostly blowing agent, (now Pentane or R-134A), with a low
thermal conductivity.
Because the gas in the cells is lighter than air, it is under constant
pressure from the surrounding atmosphere to escape the cells,
much as a balloon filled with Helium would be.
As the lighter than air gas escapes it is replaced by air and moisture,
the enemy of any insulation. As a result, the high initial R-Value of
the urethane insulation drops, thereby substantially reducing its R-
value over time.
This process, and its lowering effect on urethanes R-Value is know
as "Thermal Drift".
This effect is slowed because of the panels metal skin, but still
occurs.
Manufacturers had been reporting a 6-months aged R-Value value,
but beginning in 2003 have adopted a LTTR method (Long-term
Thermal Resistance). Based upon a method for cutting very thin
layers of foam, this method accelerates the air-diffusion and helps
to predict urethane insulations final R-value.
C & D EQUIPMENTS TOP TWO CLAIMS YOU SHOULD NEVER BELIEVE
(OR HAVE A DAMNED GOOD LAUGH AT!)
1. "I'M AN HONEST POLITICIAN"
2. "OUR INSULATION NEVER LOSES R-VALUE"
In general the LTTR values now offered by the industry for urethane insulation are:
urethane thickness initial r-value long term r-value decrease in r-value
1" 8.57 6.00 -30%
1.5" 12.86 9.00 -30%
2" 17.14 12.10 -29%
2.5" 21.43 15.30 -29%
3" 25.71 18.50 -29%
3.5" 30.00 21.70 -28%
4" 34.00 25.00 -26%
COMPARE TO OUR 4" DOW BRAND HIGH R (HIGH DENSITY) / XPS (HIGH R-VALUE EXTRUDED POLYSTSYRENE:
OUR DOW BRAND HIGH R (HIGH DENSITY) EXTRUDED POLYSTYRENE IS NOT TO BE CONFUSED WITH EXPANDED POLYSTYRENE AS USED IN COFFEE CUPS, OR WITH LOW DENSITY EXTRUDED POLYSTYRENE WHICH IS ONLY R-5 PER INCH.
OUR PANELS WHOLE PANEL R-VALUE AT 55F IS R-29
OUR PANELS WHOLE PANEL R-VALUE AT 35F IS R-30.8
OUR PANELS WHOLE PANEL R- VALUE AT 25F IS R-32.4
(OUR PANELS DO NOT HAVE A LOW R-VALUE WOODEN FRAME. WOODEN FRAMES ABSORB MOISTURE, WHICH DEGRADES R-VALUE EVEN FURTHER, AND OVER TIME CAN LEAD TO BOTH BLACK MOLD AND ROT, AS WELL AS COMPRESSION AND SINKING OF FLOORS IN COOLERS WITH FLOORS)
(Extrudeed polystyrene is not new. it was invented by former Dow research chemist Ottis Ray Mcintire, and first patented in 1944. Since then it has undergone many improvements. Resulting today in Dows High R-Value
extruded polystyrene certified to not only meet, but exceed new Department of Energy, Energy Independence and Security Act (E.I.S.A.) R-Ralue requiremets)
E.I.S.A. requires a minimum R-Value for coolers of R-25 at a 55F test temperature.
Dow's High R XPS exceeds this and is rated at R-29 at a 55F test temperature, AND IS RATED AT R-30.8 AT A MORE REALISTIC COOLER TEST TEMPERATURE OF 34 DEGREES FAHRENHEIT.
E.I.S.A. requires a minimum R-Value for freezers of R-32 at a 25F test temperature.
Dow's High R XPS exceeds this and is rated at R-32.4 at a 25F test temperature. AND PERFORMS EVEN BETTER AT A MORE REALISTIC FREEZER TEST TEMPERATURE OF 0 DEGREES FAHRENHEIT.
In short, the Long Term R-Value for urethane insulation can be as low as 6.25 per inch.

Styrofoam is the trademarked name for extruded polystyrene foam, an invention of the Dow Chemical Company that has been in production for more than 50 years.
Nearly anyone who has purchased coffee to go has heard the container being referred to as a Styrofoam cup.
However, extruded polystyrene has never been used to make disposable coffee cups. For that matter, its never been used to make portable picnic coolers either, this is another misconception.
Those products are actually made from expanded polystyrene foam (EPS) NOT EXTRUDED POLYSTYRENE.
Unlike disposable cups and picnic coolers, which are notably white in color and composed of beads packed tightly together, products made from extruded polystyrene are CLOSED CELL,
and typically blue. It is used to make insulation wrap for residential homes, commercial buildings, and plumbing systems.
It is also used in road construction as an insulation layer under pavement to deter the formation of cracks and potholes that occur from seasonal freezing and thawing of the soil beneath.
Urethane could not be used for this purpose because even though it is also closed cell, urethane in constant contact with moisture loses its closed cell properties, this is why you never see
urethane used in any application where it is in constant contact with moisture.  |
