- Internal walls, conditioned space on both sides—no requirements.
- Internal walls, conditioned space to unconditioned space (protected)—R1 (
Zones - Internal walls, conditioned space to unconditioned space (unprotected)—R2.3 (
Zones - External Walls—R2.8 (
Zones
- Residential Buildings:
- Internal Walls—no requirements.
- External Walls—R2.8 (
Zones 1 to 7 with some conditions) and R3.8 for Zone 8.
- Commercial Buildings:
- The panel was assessed for its material R-Value, which includes only the characteristics of the panel materials; and for their Total R-Value, which includes internal and external air films as would be applicable to each proposed application.
- The calculated performance for the panel arrived at comprised:
-
- 1) Panel; Material R-Value; Total R-Value in Application
- 2) PIR Panel—(6+78+6); R3.1; R3.3
- On the basis of the various assumptions it was concluded that the proposed panel satisfied the BCA thermal provisions for use in internal and external wall applications in all types of buildings for
climate zones 1 to 7. - In order to satisfy the requirements for Climate Zone 8, where a total R-Value of R3.8 is required an alternate panel size was considered to be required. For climate Zone 8a thicker panel (say 6+93+6) or the use of two panels with an air gap and a minimum of 85 mm total thickness of Polyisocyanurate material was suggested. By varying the thicknesses panels with different properties may be provided.
- The above calculations are based on a number of assumptions and are not to be construed as providing any form guarantee. Various R-values and loading strengths would be able to be calculated by standard mechanical engineering techniques.
