The Suntups family has been in the timber industry for three generations and Steven Suntup has been in the solid wooden flooring industry for 21 years.Suntup heads up the company and has handpicked the Suntups branded products from various flooring factories abroad. He also introduced the internationally patented Elastilon wooden flooring installation system to South Africa from Holland. Elastilon is used in 27 countries around the world and, now in South Africa, it has been used in the installation of over 200 000m² of flooring, with zero floor failures. According to Suntups, this is a record as expensive failures can occur when installation short cuts are taken. Elastilon ensures a stable, long-life installation. Through its experience in the solid wooden flooring industry, Suntups has taken a business decision that in future it will no longer supply full-solid timber floors as such, but will supply only Super-Engineered solid wooden flooring.
Super-Engineered wooden flooring matches full-solid wooden flooring in that it is still solid; it has the same solid wood resurface or top face thickness – of 4mm to 6mm; it is supplied tongued and grooved, in single strip planks and multiple lengths that create the same staggered finish; and it is 15mm to 21mm thick. The key difference in Super-Engineered solid wooden flooring is that instead of being one species of wood from top to bottom, it has a solid wood top face and from the tongue and groove downward it is constructed using a birch multiply. This has the advantage of making Super-Engineered solid wooden flooring 70% more stable than a full-solid wooden floor.
Problems arise with full-solid wooden floors during climatic changes which, in South Africa, can see relative humidity levels shift from around 8% in the dry seasons up to 90% at the height of the rainy seasons. Because wood is hygroscopic, full-solid wooden flooring planks expand and contract with such changes in humidity levels. This is the most common cause of floor failures and consequent expensive repairs. By contrast, Super-Engineered solid wooden flooring minimises movement in the planks during climatic changes and ensures a stable, trouble-free, solid wooden floor. A further benefit is that, with the thickness from the tongue and groove downwards being of plywood, less exotic wood is used in Super-Engineered wooden flooring and, accordingly, fewer trees are felled for its manufacture.
