A recyclable subfloor only 4 mm thick that insulates perfectly, both thermally and acoustically. Lightweight and easy to lay, without gluing. But also: easy to cut to size and combine with various heating systems. ISOBLACE is the new underlay that meets all requirements.
Yannick Koreman has worked in the flooring industry since childhood and saw that insulating subfloors were not keeping up with the times. So he decided to combine his expertise and creativity to create a new brand of subfloors that he launched this year. ISOBLACE was presented to the world during the InCoDa in September. That same month, an old monument in Goes had the premiere, where the underlay was actually used for the first time. Meanwhile, the new brand is available to wholesalers and flooring manufacturers internationally.
"In 2015 I started development and in 2019 I founded ISOBLACE," Koreman says. "I made a prototype and applied for patents for Europe and the United States. But unfortunately, a virus came along that shut things down. I then had a choice: stop or continue. I don't want to regret later the things I didn't do, so I made the choice to continue."
Meanwhile, the product has been tested by independent consulting firm Peutz and is distributed by Merford. In August 2024, ISOBLACE BASIC was launched. This does not mean, however, that the floor has already been developed, Koreman continues. "This is just the beginning. ISOBLACE BASIC is made of the plastic tpe, but there are possible applications in other, possibly fire-resistant materials. I want to see if there is a demand for biobased or residual products. I also want to expand to a roller version. Right now the subfloor consists of tiles."
That the different applications and materials are possible is because the acoustic values are achieved with the shape of the product. A honeycomb shape provides strength and air cavities provide thermal insulation. Nubs on the pressure points of the hexagon then ensure that sound waves have less opportunity to travel into surrounding areas.
Unlike many other insulating subfloors, ISOBLACE is only 4 mm thin. This is because air plays the main role. This makes combination with any top floor possible. Rigid top floors are laid directly on the subfloor; in the case of PVC, tile, cast and gravel floors, a decoupling mat or dry screed is used first. Koreman: "ISOBLACE can be used both on and under under floor heating. When it is under the underfloor heating, it stops rising cold. If the underfloor heating is underneath, ISOBLACE retains heat for an extra long time. It is even possible to lay it over existing underfloor heating. In combination with electric heating, you can insulate both acoustically and thermally with a total construction height of 5 mm. This makes the product suitable not only for new construction, but also for renovations and timber construction."
The production of ISOBLACE takes place in our homeland, the Netherlands. Koreman deliberately chose this, in order to guarantee optimal quality and continuity of the product. Sustainability is an important feature of ISOBLACE. Due to the clever structure design, where the air chambers in particular do the most important work, little material is needed in the production of the subfloor. Thanks to easy installation, there is also less loss of material. According to Koreman, the floors are particularly easy to lay. "They are suitable for the inexperienced handyman as well as the professional flooring specialist. Moreover, the material itself is easily recyclable, even as an integrated subfloor for top floors. ISOBLACE even offers the option of a subfloor made from recycled material and is itself recyclable."
