Aluminium/Zinc coated steel roofing, especially that which is made in South Africa by Safal Steel is increasingly being specified onto multi-unit residential housing projects, for the reasons given above.
However, it’s more bespoke applications catch the imagination of designers worldwide.
The Village Lane Noordhoek owner decided to roof their home using Colorplus(R) AZ150 (TCT 0.53) in colour Seaspray , which was formed into Newlok™ profile, is a concealed fix, standing seam profile with an effective cover width of 445mm, and a rib height of 50.8mm by Safintra Roofing, South Africa.
In addition to all the benefits described above, the selection of AZ150 pre-painted coated steel provides exceptional architectural/design perfomance.
1. Colorplus® AZ150 is particularly indicated for use from a distance of 1 – 40 km or more from the seas splash zone. The Village Lane House is 2km from the sea as the crow flies and represents a wise and cost-efficient decision by the specifier.
2. The specified Colorplus® AZ150 colour, Seaspray, is an excellent cool roofing choice. The amount of incoming solar radiation that bounces off a solid surface instead of being absorbed (and heating the house) is termed its solar reflectance index (SRI). In the case of the very light colour Seaspray, this index is 78, meaning that over 65% of inbound solar heat simply does not enter the roof space and simply reflects.
3. Mounted PV panels. Safal Steel issues detailed guidelines as to how this may be done and the product is an ideal backdrop for such panels, providing a number of different contours and options from which water may drain and avoiding corrosion and the buildup of dirt.
