 Most panels on the market today use two types of foam - polyurethane or expanded polystyrene (EPS). Because of the advantages of polyurethane over EPS foam – especially when it comes to the highest R-value, fire safety and moisture absorption, Cardinal Points chooses to only manufacture polyurethane foam core panels. We use the best because you deserve the best.

Thermocore pays for a fire retardant to be added to our foam.Fuel for fireExposure to HeatWill never melt.
Polyurethane is a thermoset plastic. It cannot be melted or reshaped.Not recommended for temperatures above 180 degrees due to softening (can be cut with a hot knife)

Vapor Barrier
(Moisture Resistance)

Serves as its own vapor barrier.
Permeance rating of 1.2

Vapor barrier needed
Permeance rating of 2.0 to 5.0Chemical ResistancePolyurethane is resistant to petrochemicals and other common household chemicals.EPS is highly susceptible to petroleum-based products, oils, and solvents, which can cause EPS to melt when brought in contact.ManufacturingPolyurethane bonds to the OSB skins in three ways. Adhesion, chemical and mechanical. It creates the strongest bond in the industry. Thermocore panels carry a limited lifetime warranty against delamination.EPS panels use a poly-based adhesive to bond EPS to the OSB. The glue is the only bond to the EPS. Most companies only offer a 15-year warranty.CostThermocore panels are often equal or lower costs when compared to EPS while providing more standard features than any EPS company. With Thermocore there are no added costs associated with lumber/lumber install or any upcharge from your electrician to wire your panels. We take care of the electrical at our plant.EPS panels do not typically come with door and window bucks included. It is an added charge. You will also have to pay a significant upcharge to have your electrical run as EPS companies DO NOT include electrical boxes and conduit, installed custom, as part of their package.¾ ConduitIncludedDrilled Case (avg $5/ft)4x4 Electrical BoxesIncludedElectrician added in fieldDoor & Window Cut OutIncluded with CNCAvg $200/windowWindows & Doors Framed 2x4’sIncludedAvg $75/frameRoof Ridge Plum CutIncludedAvg $6/ftSub Fascia in PlaceIncludedAvg $3.50/ftMolded Foam SplineIncludedAvg $4.50/ftSill PlateIncludedOwner SuppliedTop Plates, Corners & NailsIncludedExtraBeam Pockets & Column SupportsIncludedAvg $250/pocket
