Part two audio demonstration

  1. 1. What is R-value ?
  2. 2. R-Value - Key Points <ul><li>R-value is a measurement of R esistance to heat flow </li></ul><ul><li>R-value is measured using international standard laboratory test methods (ASTM-xxxx) </li></ul><ul><li>R-value is used to evaluate insulation materials </li></ul><ul><li>but can also be used as a performance measure of wall/ceiling/floor systems </li></ul><ul><li>More than one method of measuring R-Value </li></ul>
  3. 3. How is R-Value measured ?
  4. 4. Measures thermal resistance of product sample using heat flow meter Testing for R-Value Guarded Hot Plate Apparatus - ASTM C518 Most common R-value test Done with material samples in machine Used for labels on insulation products Measures primarily conductive heat flow Quick and inexpensive test
  5. 5. Heat Transfer Percentages
  6. 7. Installed System R-Value Testing
  7. 8. Installed System R-value Testing ASTM C1363 <ul><li>Measures the performance of insulation </li></ul><ul><li>as used (installed) e.g.. a frame wall system </li></ul>Test measures insulation and effects of other wall components (framing, sheathing, air infiltration, air spaces, etc.) Test performed at real world temperatures (interior versus exterior) Measures all types of heat transfer - combined (conduction, convection & radiation)
  8. 9. Other factors measured by installed system performance test <ul><li>Thermal Bridging </li></ul><ul><li>Transfer of energy through framing members </li></ul><ul><li>Insulation is installed between framing </li></ul><ul><li>Framing (less thermal resistance) conducts energy in/out </li></ul><ul><li>Framing can amount to as much as 25% of a structure </li></ul><ul><li>Thermal transfer with concrete and metal even greater </li></ul><ul><li>Air infiltration </li></ul><ul><li>Transfer of energy through air movement </li></ul><ul><li>Heat is attracted to cold </li></ul><ul><li>Air drafts in building envelope </li></ul><ul><li>Can affect heat loss by as much as 35 % </li></ul>
  9. 10. How Does 25mm P2000 Perform compared to 150mm of Fiberglass? Measures conduction of insulation material sample using heat flow meter Material Sample Testing - ASTM C518 0.72 3.35
  10. 11. Measures combined effects of wall system - including thermal conduction, thermal bridging through frame members and convection currents within wall Installed System Testing - ASTM C1363 1.8 2.02 0.72 3.35 How Does 25mm P2000 Perform compared to 150mm of Fiberglass?
  11. 12. Moisture reduces performance of fiberglass insulation because moisture droplets in effect conduct energy through fibers at a faster rate 1.5% moisture = reduced performance of 26% ASRAE study What About Moisture? 1.8 1.74 1.8 2.02 .72 3.35 How Does 25mm P2000 Perform compared to 150mm of Fiberglass?
  12. 13. Improper installation such as compression and poor fitting in stud cavities can also reduce the effectiveness of fiberglass. Installation Deficiencies 2.02 1.8 ?? 1.8 1.74 1.8 0.72 3.35 How Does 25mm P2000 Perform compared to 150mm of Fiberglass?
  13. 14. Air leakage accounts for as much as 35 % of heat loss in a building envelope. Air Infiltration 1.8 ?? 1.8 ?? 1.8 1.74 1.8 2.02 .72 3.35 How Does 25mm P2000 Perform compared to 150mm of Fiberglass?
  14. 15. Summary <ul><li>Material sample R-value testing and installed system </li></ul><ul><li>R-value testing yield significantly different results </li></ul><ul><li>Installed performance testing is a more specific and </li></ul><ul><li>reliable measure of insulation performance because </li></ul><ul><li>it looks at the combination of factors present in a </li></ul><ul><li>specific wall/ceiling system </li></ul><ul><li>Material sample tested (labelled) R-values are assumed </li></ul><ul><li>to be a reliable indicator of installed performance </li></ul>
  15. 16. Which is the most meaningful test of insulation performance ? Installed System Testing Material Sample Testing OR
  16. 17. Which is a best indicator of an energy efficient building? A building with high R-value? OR A building that uses less energy?
  17. 18. How is P2000 an efficient insulator “ dead air space” be built into a practical construction material ?
  18. 19. Expanded Polystyrene Foam (EPS)
  19. 20. Expanded Polystyrene 1000s of Air Pockets Magnified 100 x Magnified 1500 x 90% + air / volume
  20. 21. We trust the Polystyrene Cup 2 mm of efficient insulation Common R-value testing does not measure its complete performance of other insulation materials like: Thermos Space Suits Polystyrene cup
  21. 22. P2000 - Air Tight Thermal Panel Non conductive Reflective Radiant Barrier P2000 Special EPS Non conductive Reflective Radiant Barrier
  22. 23. <ul><li>Engineered system uses EPS formula foam core </li></ul><ul><li>Core is 90%+ air / volume </li></ul><ul><li>Faced with durable, radiant reflective skin </li></ul><ul><li>Lightweight, easy to cut & fit </li></ul><ul><li>Proven effective insulator in many applications </li></ul><ul><li>EPS documented as the most stable & long-life insulation building material </li></ul>What makes P2000 Insulating System efficient?
