AL- RASHED POLYSTYRENE COMPANY / Technical Data

Following tables are intended as a guide only, for the use of designers in developing concepts. Users should contact the panel manufacturer for further information.

Table A – Thermal Resistance

Thickness (mm)	50	75	100	150	200
R Value (m² k/w)	1.32	1.97	2.63	3.95	5.62
Note: In choosing panel thickness, structural capacity should also be considered.

Table B – Panel Weights

Econotil

Thickness (mm)	50	75	100	150	200
Weight (kg/m²)	9.6	10.0	10.4	11.2	12.0

Econodeck

Thickness (mm)	75	100	125	150	200
Weight (kg/m²)	10.2	10.6	11.0	11.4	12.2
Note: Panel weights may be subject to minimal variance according to styrene density.

Table C - Wall Panel Spans for typical wind loads

Thickness (mm)	75	100	125	150	200
Span (mm)
Protected and/or Urban Areas	4500	5000	6000	6500
Partly Exposed	4000	4500	5500	6000	7000
Fully Exposed	3500	4500	5000	5500	6000
Note: Based on a building height of 6 metres, 41 metre per second wind seed. Figures allow for local pressure co-efficient (AS1170.2).
