Polyurethane Vs. EPS (Expanded Polystyrene)
Polyurethane is a relatively new product, roughly around 35 years. EPS has been with us for around 50 years. Polyurethane was produced
to replace the shortfalls of expanded polystyrene. Below you will see a detailed difference between polyurethane, and expanded
R- Value - Polyurethane is the highest rated insulation in the world. You will find it in most all of your refrigerators, freezers,
and even in your personal carry about coolers. Per inch of insulation it has no equal. The walk in coolers and freezers that we
manufacture for use thought the country are made of polyurethane. That is why we think R-value is important. EPS has a value of
R-2 to R-5 per inch.
POLYURETHANE HAS AN R-VALUE OF R-7 TO R-8 PER INCH. How much value do you put on your home?
Moisture Resistance - With all the problems of mold and mildew, moisture resistance is today a very important factor. Polyurethane has
one of the lowest moisture Permeability ratings of any product manufactured for the building industry today. The permeance rating on
our polyurethane is 1.2. The permeance rating on EPS is 2.0 to 5.0
This difference in a high humidity area would warrant another moisture barrier for EPS panels. In calculating R-values, some EPS
manufactures use these additional moisture barriers in their calculations.
Fire Resistance - The polyurethane that we use is a UL Class 1 rated foam. This means that our polyurethane is
not a source
for fire. On it's own, our polyurethane will not burn. When left on it's own, it will extinguish it self. A Class 1 rating is the
highest rating a building product can obtain. Also, polyurethane is a thermal-set plastic. This means, that it will not melt.
Our polyurethane is not affected until temperatures reach 1000 degrees and at that time it will only char. EPS on the other hand is
not a thermal-set plastic and will begin to soften at temperatures of 180 degrees, and melt at temperatures of 240 degrees.
Polyurethane has a distinct advantage.
DENSITY - The density of a product will determine the strength of it. EPS has a density of 1 lb. The polyurethane that we use has a
density of 2.2lb. Advantage polyurethane.
CHEMICAL RESTANCE - Polyurethane is resistant to most counter chemicals. EPS react violently to petroleum based products. PL 400 and
liquid nail will literally burn thru EPS.
MANUFACTURING - Probably the biggest difference between Polyurethane and EPS is in the manufacturing of these panels. Both products
use OSB for covering both sides of their foam, but here is where the similarity ends. In the bonding of the foam to the OSB we use
the polyurethane itself. Polyurethane is one of the best glues used in the industry today. Some
manufacturers of OSB and plywood use
polyurethane to bond their products together. When it comes to adhering, the use of polyurethane gives us both an excellent R- value
and the strongest bond in the industry. EPS panels use glue spread on both sides of the OSB, and then the OSB is match together
with the EPS, and mechanically held in place and under pressure until the glue is dried.
One can understand why there are more EPS manufacturers than Polyurethane. We feel that the investment made equals the quality of
product made. We believe that there is no comparison between our panels, and those of EPS
manufacturers. We by far offer a better
product hands down.
The age-old proverb is still true today. YOU GET WHAT YOU PAY FOR.
