Most wooden flooring put in in plank or strip format is predictable in the way it performs and is put in. “Conventional” wooden flooring codecs have weaknesses by way of particular efficiency attributes. For many years, producers have tried to design merchandise with options to fight identified efficiency points, together with dimensional stability, resistance to static and dynamic hundreds, and colour consistency. Whereas product design components of engineered buildings usually contain substituting the plywood core with different core supplies to enhance hardness and dimensional stability, chemical and bodily adjustments to the lumber or ornamental wooden veneer even have been carried out to attain related efficiency enhancements. Area of interest markets had been fashioned round these “atypical” merchandise exhibiting enhanced efficiency.
Thermal remedy of wooden has been used for many years to enhance wooden’s properties in opposition to dimensional adjustments in extreme environments and degradation to fungal assault. The thermal remedy course of degrades sure chemical constituents within the wooden cell wall, limiting its applicability primarily to non-structural merchandise. Engineered wooden flooring producers experimented with thermally handled face veneers on flooring merchandise. They believed that thermally handled veneers may handle a few of the dimensional problems with wooden flooring whereas offering distinctive, wealthy aesthetics. These producers shortly found that the thermally handled veneers had been too tender to carry out effectively long-term, exhibiting vital indentation and gouging.
Different, extra commercially profitable applied sciences had been developed and carried out to enhance bodily efficiency. Some proprietary strategies had been invented to fill the void house in wooden with totally different polymers cured or hardened with stress and warmth. The ensuing wooden product is dense and extremely immune to indentation from static and dynamic hundreds, making it a perfect possibility for many gentle industrial purposes. This know-how sometimes doesn’t considerably alter the wooden’s dimensional properties as a result of the chemical substances don’t alter the wooden cell partitions. Different wooden chemical remedy applied sciences alter the wooden cell wall to enhance dimensional stability or improve bodily properties.
Alternate proprietary applied sciences had been developed to extend the hardness and bolster the dimensional stability of wooden. Managed compression of heated and plasticized wooden improves the indent resistance considerably. The heating course of is achieved otherwise and happens under the temperatures of conventional thermally handled wooden utilized in exterior purposes.

The Science of Atypical Wooden Flooring
Pre-Expo Symposium
Tuesday, April 16 | 10:00 a.m. – 3:00 p.m.
Moderator: Dr. Brian Beakler
Panelists: AHF Merchandise, Carlisle Vast Plank, Dinesen Flooring, Kaswell Flooring Programs, Olde Wooden Ltd., Oregon Lumber, and Välinge/Bjelin
Strain utilized to the heated wooden reduces the void house, growing the wooden density. In flip, the wooden turns into extremely indent-resistant.
The remedy strategies described are advanced and make manufacturing these merchandise dearer. Nonetheless, these merchandise have efficiency attributes that allow them for use successfully in environments the place different conventional wooden flooring can not.
The aesthetic needs of designers and customers have created further atypical product classes. Many firms have specialised in providing vast (12”+) and lengthy plank (12’+) merchandise to satisfy the rising market demand for these codecs. Nice care is required in designing, manufacturing, and putting in vast and lengthy plank merchandise. Vast, long-format engineered wooden flooring merchandise can present cupping and crowning extra prominently if not fabricated, saved, or used appropriately. Inner stress growth from various environmental situations may cause cracking of the face veneer on vast planks earlier than and after set up.
Along with vast and lengthy planks, reclaimed wooden continues to develop in recognition. Reclaimed wooden flooring has a wonderful reuse story, and its rustic visible caters to many designers and customers. Wooden flooring utilizing reclaimed lumber or reclaimed wooden has challenges. Producers should pay extra care to make sure the reclaimed wooden is dried appropriately and adequately sterilized to eradicate beetle larvae. Some reclaimed wooden can also comprise contaminants within the type of heavy metals (lead-based paints) and different chemical substances.
Finish grain flooring is a product that has been in use for a lot of industrial and residential purposes for effectively over a century. Finish grain flooring is hard and indent-resistant. It additionally offers a singular visible in lots of codecs, together with squares to rectangles. This product additionally has totally different challenges concerning dimensional stability and set up.
As new wooden applied sciences and visible tendencies influence wooden flooring customers sooner or later, it’s more likely to assume that we are going to see extra atypical classes, every with its personal set of challenges. The merchandise and applied sciences briefly highlighted on this article will likely be mentioned in additional element by key producers of those merchandise through the NWFA Pre-Expo Symposium: The Science of Atypical Wooden Flooring. Panelists will talk about manufacturing challenges, set up nuances, and what to search for when sustaining and inspecting these merchandise.
