Polyisocyanurate, also referred to as PIR or ISO, is essentially an improvement on polyurethane (PUR). Different catalysts are used and the proportion of methylene diphenyl diisocyanate (MDI) is higher than for PUR. Instead of a polyether, a polyester derived polyol is used in the reaction.
Say it 10 times fast and the word is yours forever.
I love saying this 8 syllable word and it can help your next building project be green.
This product can help your home or office building save money as well as lowering your carbon footprint by reducing your need for additional tonnage for the HVAC system.
1. It has been cited by the EPA for being responsible to the environment.
2. It is commonly used in construction for Energy Star homes.
3. Reduce carbon footprint reduce emissions by increase in R- value in construction.
4. Can help create air and draft tightness in construction. Following Energy Star guidelines.
5. Highest R- Value per inch.
6. Moisture resistant
7. Recycled product.
8. Superior performance in fire tests – Class 1 Approvals and UL 1256/ULC S126
9. Continuous insulation performs much better then cavity insulation with the same r- value because the rigid insulation does not allow a thermal bridge and reduces air leaks.
10. You can achieve LEED points in these areas listed below
- Energy and atmosphere
- Materials and resources
- Innovation and design process
U.S. EPA compliant hydrocarbon-based blowing agent which has zero Ozone Depletion Potential (ODP) and virtually no Global Warming Potential (GWP).
CFC and HCFC free specification requirements.
