There are a variety of ways to determine thermal performance in a building envelope.  The important thing to keep in mind is that P2000 is a SYSTEM.  Below is a brief description of the issues that affect the performance of a building’s thermal package, as well as how the P2000 Insulation System addresses each issue.

The P2000 Insulation System was developed as a means of producing a single building product that would effectively address common issues that plague conventional insulation products when installed in a building envelope:

  • Conductive heat losses
  • Air leakage and convective heat losses (up to 35% of heat losses)
  • Moisture infiltration
  • Radiative heat losses (up to 55% of the heat transfer in ordinary air spaces)
  • Installation deficiencies (30% to 40% of residential structures do not follow nominal framing patterns)
  • Thermal Bridging (up to 25% of a building’s surface area is framing)
  • Long term stability

The effects to which each will contribute to the overall thermal transfer process will depend on the design, configuration, and integrity of the building envelope as well as climate conditions.

Included in the Architectural Specification Package are some typical methods of calculating wall R-values.  Testing has revealed that the core of the P2000 RPR system has an R-value of 3.9 (Canada) to 4.1 (United States), slightly better than EPS.  However, when tested as a part of the building assembly, considering only thermal bridging and component orientation, it was found that a 1″ P2000 system performs equivalent to a 5.5″ fiberglass wall system.

In the real world, air infiltration is a common issue, accounting for as much as 35% of heat loss/gain in a building envelope.  P2000′s unique double flap sealing system combined with the use of seam tape for end joints, allows an air tight building envelope to be easily achieved in most installations.

In addition to addressing radiative heat loss/gain, the proprietary facers function effectively as water and vapor barriers, thus minimizing moisture infiltration which can seriously degrade the effectiveness of some insulations.

The thermal stability of EPS has been thoroughly documented in long term tests.  As such, P2000′s core is expected to retain its thermal performance over time.  It is lightweight, easy to install and qualifies for up to 26 LEED points.

We have received confirmation from the International Code Council Evaluation Service (ICC-ES) that P2000 Insulation complies with the provisions of the 2006 International Building Code (IBC), International Energy Confirmation Code (IECC) and the International Residential   Code (IRC).

ICC-ES report #2222 provides guidance to code officials approving the use of P2000 Insulation under the above codes.  The report is available online at www.ICC-ES.org

P2000 Insulation meets or exceeds UL standards, testing , approvals, certifications, US and Canadian Codes.  Technical and Specification sheets are available  in the testing section.

We are continually using professional, third party engineers from Canada and the United States to ensure that the energy savings of P2000 are validated and certified.

If you have any further questions, feel free to contact your local P2000 Representative.  They will be more than willing to work with you to help you fully understand the effectiveness of the P2000 Insulation System.
