EPS-FR Specifications

ThermLoc Fire Retardant EPS PanelsTherm-Loc panel is a lightweight, structural, continuously manufactured insulated sandwich panel with a range of thicknesses of internal & external skins of colorbond steel laminated to a core of expanded polystyrene (EPS) insulation in a variety of densities.

Therm-Loc panel is available in a range of thickness, length, with a standard width of 1200 mm with either flat or ribbed surface finish & a variety of colors.

Thermal insulated panel doors are manufactured in a wide range of types, slide, hinged, up lift, bi part any type is achievable. All doors are manufactured using many of Thermal’s exclusively designed extrusions, tracks rollers, guides, locks, handles, gaskets etc to a extremely high quality finish all heavy duty construction.

Panel Joint detail:

Recommended Maximum Spans for Ceiling Panels

The recommended maximum span table below is for Therm-Loc sandwich panel ceiling with 0.6mm thick steel skins bonded to an expanded polystyrene foam core.

The span table is for a panel ceiling which is subjected to a live load only, which is not in excess of the ‘Roof Live Loads’ for non trafficable roofs as set out in clause 3.8.1.1 of AS 1170 part 1, which makes an allowance for a minor live loading occurring in maintenance and repair operations.

Ceiling subjected to wind loads, or other dead or live loads are not covered by this table.

Ceiling support or suspension systems must be adequate for the applied loads.

Ceiling panels in low temperature cold room applications could be subjected to internal pressure conditions which would require a reduction in these maximum recommended spans.
