Hunter Douglas Shademaster

The Shademaster® Insulmax Story

Insulmax insulated roof panel is manufactured in Australia by Hunter Douglas Limited, a world leader in the highly specialised field of applying paint to aluminium and steel.

Beautiful Contemporary DesignShademaster® Shelter Systems products are painted using the exclusive HD Color-cote® Thermosetting Polymer Paint System, at the Company's high-tech complex in Sydney Australia, where the Company has been operating since 1956.

Hunter Douglas Shademaster® Insulmax Insulation Roof is actually a roof and ceiling in one, capable of spanning up to six metres and strong enough to walk on.  It is ideal for add-on leisure and entertaining rooms, patios and carports, with impressive insulating properties for year-round climate control.

The roofing is available in a range of thicknesses, to suit application, with made to order lengths up to 9 metres.  The panels are 580mm in width, featuring a top and bottom skin of high grade.42 G550S@ - AZ150 steel with expanded polystyrene (EPS) between.  This is a closed cell, lightweight cellular plastic material, modified by the addition of flame retardant additives.  It has excellent insulating properties and is moisture resistant, providing superb temperature control all year round.  The polystyrene not only insulates, but also eliminates the problem of condensation (and with it, the inevitable mould and mildew).

The surface of the panel is finished in the highly durable HD Color-Cote® Polyester Coating, the same paint process as used for such high profile exteriors as the panelling on Stadium Australia which hosted the 2000 Olympic Games.

Shademaster® Insulmax Insulated Roof features a high gloss polyester surface on the roof (top skin), with an attractive "low gloss" finish for the ceiling side (under skin).  Panels clip together to form a weather-tight seal with the joint designed to be virtually undetectable.

For letting some light into a dark patio area, Shademaster® Insulmax Insulated Roof offers the perfect solution - the additional option of Naturelit Panel.  Using a specified set of adaptors, designed by Hunter Douglas exclusively for its Shademaster® Insulmax Insulated Roof, the Naturelite panels may be easily installed with the 55mm panel, providing both functionality and style.

Insulmax Insulated Roof Panl has come to be recognised as the flagship product of the Shademaster® Shelter Systems Home Improvements Products range.

The Shademaster® Name is synonymous with quality, durability and excellence.  Hunter Douglas Limited is a quality endorsed company and certified as complying with the requirements of AS/NZS ISO 9001:2008
