Polyisocyanurate Rigid Foam Insulation Board

It s made of environmentally sound closed cell polyisocyanurate foam bonded to a durable white matte non glare aluminum facer and a reflective reinforced aluminum facer.
Polyisocyanurate rigid foam insulation board. Polyisocyanurate pir is one of the most efficient insulation material used in construction. Polyiso and other rigid foam insulation boards are low density products. However when thermasheath 3 was tested in a wood framed symmetrical wall specimen 5 8 fire code gypsum face layers thickness 4 with 2 thermasheath 3 in stud cavities to exterior per the astm e90 test method the assembly. They are not intended to be used as sound deadening or sound absorbing materials.
R matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation r matte plus 3 thermasheath 3 is rigid foam plastic thermal insulation board. Polyisocyanurate also referred to as pir polyiso or iso is a thermoset plastic typically produced as a foam and used as rigid thermal insulation. Polyiso insulation count on iko for the best in polyiso. 0 75 in x 4 ft x 8 ft.
The starting materials are similar to those used in polyurethane pur except that the proportion of methylene diphenyl diisocyanate mdi is higher and a polyester derived polyol is used in the reaction instead of a polyether polyol. Polyisocyanurate polyiso is a closed cell rigid foam board insulation that is bonded to facers on both sides which are composed of various organic and inorganic materials. Ikotherm polyisocyanurate roofing insulation is constructed from a closed cell polyisocyanurate foam core bonded on each side to glass fiber reinforced kraft facers during the manufacturing process.
