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.

The higher R-value a material has, the more effective it is at keeping out cold. Therefore, the higher the R-value for a total project, the better insulated the building will be. If a wall, for example, is made of plywood sheathing, studs and drywall, the R-values of each of these three materials should be added together for the total R-value. R-values for these walls are lower than hollow timber frame walls, as the wall materials have natural insulative values. Zones 1 and 2 have required values of 3 and 4, Zones 3 and 4 have a required value of 5. Zones 4 marine and 5 have a required value of 13. Zone 6 requires an R-value of 15, and zones 7 and 8 require a value of 19. Floor R-Value R-Values. The R-value is a measure of resistance to heat flow through a given thickness of material. So the higher the R-value, the more thermal resistance the material has and therefore the better its insulating properties. The R-value is calculated by using the formula . Where: l is the thickness of the material in metres and R-value refers to a material’s ability to resist heat transfer at a certain thickness. When looking for a material to insulate your building you would generally look for a material with a high R-value, and therefore, one that can resist heat transfer well. While K-value deals solely with just the material, R-value refers to the material and The R-value at 180 day real-time age and 75ºF mean temperature is commonly used to compare products and is the value printed on the product. Values at yield or 10% deflection, whichever occurs first. Value at yield or 5%, whichever occurs first. Data ranges from 0.00 to value shown due to the level of precision of the test method. For the brick veneer/Celotex the best solution is to leave the Celotex and apply XPS between the studs held in place and sealed with sealant, non-solvent-based and foamed where necessary. Creating an air-moisture-thermal (AMT) barrier. This should deliver an assembly R-value of 9 mas e menos. 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.

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.

For the brick veneer/Celotex the best solution is to leave the Celotex and apply XPS between the studs held in place and sealed with sealant, non-solvent-based and foamed where necessary. Creating an air-moisture-thermal (AMT) barrier. This should deliver an assembly R-value of 9 mas e menos.

R-VALUE. R-value is used to measure materials ability to resist heat or in other words, resistance of a material unit to heat transfer. R-value figure is usualy provided by the manufacturer of a particular insulation product and is shown in the product description. R-value figure can be calculated from the equation:

Celotex insulation boards are the ideal product whatever you thermal insulation needs are. Here is a breakdown of the range by function: The unique Celotex online U-value calculator generates a U-value specific to the chosen construction and enables you to input a range of different construction parameters to evaluate their impact on thermal
