Typical Polyisocyanurate insulation R-Values Polyisocyanurate insulation products have an R-value of about R 7.04 to R 7.20 per inch. Shown in the photo, Celotex Thermax solid foam insulating board with aluminum foil facing. With a stabilized 3/4" air space on one side of this insulating board its R-value at 1" increases to R10.
R-value measures how well certain building insulation materials can resist heat. The higher the R-value, the greater the insulation performance. When determining how much insulation you need, don't guesstimate, calculate. Know exactly how much you need with our project calculators. Jump to Specific Section. Celotex GS5000 is purpose designed for providing better U-values and thinner solutions in solid wall upgrades and other dry-lining applications including timber frame constructions and the underneath layer of between and under build-ups in pitched and It provides R-values that range from 3.6 to 4.2 per inch. Some products have reinforced facing to make them sturdier. • Extruded Polystyrene. Choose this option for areas that need a good amount of strength and water resistance. It provides about R-5 per inch. • Polyisocyanurate. This material offers the highest R-values—about R-6 to 6.5. R-value is the temperature difference per unit of heat flux needed to sustain one unit of heat flux between the warmer surface and colder surface of a barrier under steady-state conditions. The R-value is the building industry term for thermal resistance "per unit area." It is sometimes denoted RSI-value if the SI (metric) units are used.
Scheduled Values for the Celotex Asbestos Trust. Valid Individualized Review Claims (IRC) claims will be evaluated and offered gross settlement values comparable to the values paid in settlement by Celotex or Carey Canada prior to filing for bankruptcy protection. The Trust will pay a variable percentage of the gross settlement value.

R-Value actually stands for “resistive” value. U-Factor is a measure of a component assembly in its conductive and radiate capacities. Let me explain… when the general public hears an R-13 wall insulation, they believe that in fact they have an R-13 insulation value in their exterior walls. The truth is this, studs have an R-value of 3.5.
The product is used as external sheathing that provides a R-Value of 1.3, more than doubling the R-value of OSB and gypsum; and six times more effective than thermo-ply or other foil-faced paperboards. Builders may replace costly OSB and plywood corner bracing with T-Bracing and PREMIUM INSULATING SHEATHING.
