Sarnatherm® ISO tapered is a sloped rigid closed cell polyisocyanurate insulation board with fiber reinforced felt facers. A spray foam roofing system has an R-value of 6.6 per sq. Here are the installation methods from lowest to highest average R-value per inch: Blown-in (or loose-fill) insulation; Insulation blankets (batts and rolls) Spray foam insulation; Foam board insulation ; Note that the material the insulation is made from will change the R-value as well. IKO Enerfoil sheathing wall insulation is a rigid, polyisocyanurate foam insulation board with high thermal properties. To convert the R-value of a specific thickness of a material to RSI, divide the R-Value by 5.67826. EPS can be used for ground contact and does not retain water over time. ... predicting product R-value after five years, which is equivalent to a time-weighted thermal design R-value for 15 years. Sarnatherm Tapered is designed to achieve positive drainage, prevent ponding water, and is suitable for use in new construction and re‐roofing with Sarnafil® or Sikaplan® membranes. CREATES A MOISTURE BARRIER Vapour barrier product. Cost Of Rigid Foam Board Insulation. Polyiso can be installed on both commercial and residential structures, on the roof or in the wall. This is Used Poly Iso Insulation which comes from different de-construction projects. It is used in over 70% of commercial and residential markets for both wall and roof applications. Polyiso insulation has the highest R-value per inch of thickness of any type of insulation. With a wealth of experience in the Industrial sector as well as the domestic Insulation markets. SOPRA-ISO PLUS is a closed-cell polyisocyanurate foam insulation board laminated with a polymer-coated glass fibre facer. Tapered ISO 95+ Polyiso Insulation Extend the life of the roof assembly by eliminating problems associated with ponded water . Polyisocyanurate thermal insulation, also referred to as polyiso, PIR, or ISO, is a popular low slope commercial building roof insulation. We recommend having at least 20 r value … The reported values were the average of the results from the fifteen test samples. R-value is used in the United States. There are different ceiling insulation products available in South Africa. ISO Board or Polyiso Insulation Boards Chart. Polyiso is unique in that the R-value increases with the thickness of the foam, so three inches of polyiso has a higher R-value per inch than two inches. Most of the time, spray foam can be directly applied to existing roofing systems, but in some cases, a polyiso board is needed. Figure 3: Service temperature R-value test results for nominal R-12.1 (LTTR) / R-11.2 (NRCA) insulation. Expanded Polystyrene (EPS) With the highest R-value per dollar, EPS is used for roof, wall and floor insulation. Wall energy star certification means that it clearly contributes to reducing energy consumption. CertainTeed FlintBoard® ISO Polyisocyanurate Roof Insulation features a closed-cell polyiso core integrally laminated to heavy, black (non-asphaltic), fiber-reinforced felt facers. Benefits. ACFoam ® Tapered Roof Insulation helps prevent material waste, reduces the roof profile, and reduces fastening costs. You should, of course, see the manufacturer-provided technical data sheet for the R-value of specific products. Extruded polystyrene foam (XPS) also known as blue board or pink board comes in many different thicknesses and edge profiles. It is a thermoset, closed-cell foam that is an optimal insulation solution for low slope roofs. The average R-Value is R-5. ISO R PLUS premium makes it possible to insulate the house from the inside, eliminating thermal bridges. ACFoam ® Recover Board is manufactured and tested for use in recover applications, ACFoam Recover Board is a rigid polyiso roof insulation faced with inorganic coated polymer-bonded glass fiber mat facers. With premium polyiso manufacturing, Atlas is able to produce the highest effective R-values with minimal material thickness. ISO 95+ Polyiso Insulation High-energy efficiency through the highest R-value ratings per inch versus other insulation materials . Compact High R-Value System ... Sarnatherm ISO is a rigid closed cell polyisocyanurate insulation board Sarnatherm® ISO is a rigid closed cell polyisocyanurate insulation board with fiber reinforced felt facers, and is suitable for use in new construction and re‐roofing with Sarnafil® or Sikaplan® membranes. The most efficient and best insulation used is rigid foam (Polyiso); it accounts for over 60% of all installs.. ISO is available in a range of thicknesses, that come in increments of 1 inch. Poly ISO insulation board may be installed over approved decks and substrates on new construction, tearoffs and recover (retrofit) projects. XPS is semipermeable with a perm rating of 1.
