Viking SuperStrand specifically designed for CertainTeed Shingles

What is SuperStrand?

Viking SuperStrand is an H3.1 treated strand board; designed by Juken New Zealand specifically as a substrate for asphalt shingles.

As SuperStrand is more rigid and spans further than plywood, it reduces the visibility of sheet joins and any unevenness in the structure creating a flatter and sharper looking roof.

Viking Superstrand In Action

Why is it H3.1 treated?

A treated substrate, H3.1, provides the home owner with peace of mind. The New Zealand Building Code sets the minimum standard. It does not require a treated substrate, for asphalt shingles, unless the building has a skillion roof.

SuperStrand follows best practice by providing a treated substrate, at no extra costs.

Lightweight Roof

Quality Assurance

Viking SuperStrand has been BRANZ appraised, when used in conjunction with our asphalt shingles.

What does this mean? Well, it has been independently tested in New Zealand, by BRANZ, to ensure it can handle New Zealand's harsh conditions and complies with the New Zealand Building Code.

Working with Viking SuperStrand

Viking Approved Applicators who have worked with Viking SuperStrand have found that it is:

  • Faster and easier to install as there is no tongue and groove requirements

  • Easy to handle, carry and pass up through the trussed and onto the roof due to the narrower sheet width, at 800mm

  • With every strand of the board exposed to the preservative treatment, cut edges do not require further treatment on site

  • Provides less wastage as SuperStrand has no face grain so it can be laid in any direction, with a maximum span of 900mm

Environmentally friendly

The azoles and permethrins used to protect the board against fungal decay and insect attack respectively are water-based treatments, so no solvents are used. The preservatives used are organic biodegrade compounds.

The manufacturing process ensures that every strand is treated to H3.1 before the board is made. This ensures that the treatment is distributed throughout the full thickness of the board (unlike mainstream treatment processes). Any cut edges or penetrations do not require further sealing in order to maintain full protection.
