COMPLIANCE
The Wind Capacity Tables are based on testing in accordance with AS1562.1-1992 and AS4040.0, 1 & 2-1992. Span
tables have been developed by determining wind pressures in accordance with AS4055-2006 for domestic applications.
Capacity tables are in limit state format.

DESIGN CONSIDERATIONS
The minimum recommended roof pitch for “flat”
verandahs shall be 2° (1 in 30) for Cooldek Classic panels
and 3° (1 in 20) for Cooldek CGI panels. The maximum
roof pitch for “flat” verandahs shall be 5° (1 in 12). Care
must be taken to ensure the minimum roof pitch is
maintained to avoid ponding of rainwater.
The roof is designed to withstand actions incidental to
maintenance, roofs are not to be used for floor type
activities.
The design contained within these span tables relate to
wind classifications N1, N2, N3, and N4 applicable to
Regions A & B. Stratco does not accept liability for any
loss or damage suffered as a result of any errors in the
interpretation or application of these span tables.

FORM AND FUNCTION
The innovative Cooldek
®
insulated panel provides a roof, insulation and ceiling like finish all in one product. With
superior spanning capabilities, two roof profiles and three insulation thicknesses to choose from, it is an ideal solution
for domestic patio roof applications.

SPANS
Spans given in table 2 are determined for wind speeds for
non-cyclonic areas. Indicated spans are suitable for ‘flat’
roof patios. Open freestanding unit spans can be taken
from open three sides unless a wall, eaves or boundary
exists within 500mm of two or more sides.
For Cooldek roofing in attached or freestanding domestic
gable patio application, sheet spans shall not exceed
those given for one or no open sides. Alternatively, table
3 indicating wind capacities may be used to determine
allowable single spans for any application.
Spans specified for units with three sides open are
suitable for units considered ‘empty under’ and not
exceeding 3 metres in height (from ground or deck
level). For units in which goods or materials stored under
the roof are expected to block greater than 50% of any
open side exposed to the wind spans are to be taken
from open two sides.
For units with two open sides, spans are based on Cp,n=-1.0
while for units with only one or no open sides, Cp,n=-1.2.
In all cases, relevant consideration has been given to
local pressure.
Note: Table 3 provides allowable wind capacities for
Cooldek in single span application for serviceability and
strength limit states. The pressures given may be used by a
suitably qualified engineer for any single span application
ensuring appropriate fixing details are applied.
