Polyisocyanurate insulation / Guides

...Insulation Products, Like Hemp Insulation panels or Batt Insulation or mineral wool - demonstrated here in roof insulation . Polyisocyanurate Foam Panels: PIR, polyiso, or ISO, is a thermoset plastic product typically produced as a foam and used as rigid thermal insulation panel - most often with aluminum foil faci...

...insulation [polyisocyanurate and stone wool ], measurements of R-value per inch were made over a range of different temperatures more characteristic of in-service temperatures. As shown in Figure 1 below, these measurements found that the R value of both insulation types change with temperature, with the polyisocyanura...

...insulation panel that one day we hope will replace plastics based foam as a standard building insulation. And better still is when the natural alternative for these plastic based rigid foam insulation boards is a naturally derived cellulose high-performance panel with a higher R-value than current rigid insulation pane...
