weber.therm circle | The first recyclable by type ETICS
weber.therm circle is the first ETICS which can dismantled and recycled by separation of each material type. Once it has reached the end of its service life, again new high-quality products are obtained from the sorted components.
Zero Waste. Building better.
Construction activities in Germany consume around five million cubic metres of insulating materials and 100 million tons of sand, among other things, every year. Real estate is a long-term investment, but it is always undergoing changes, such as additions or conversions. In these cases or during dismantling, the building materials are disposed of in a mixed way and are thus lost for further use in building construction. Our society can no longer afford this expensive and ecologically unsatisfactory process.
The lack of recyclability of thermal insulation composite systems was a major criticism of this and other composite construction methods from the outset. As the word "composite" already expresses, all components are bonded one to another, so that they only can be disposed of mixed together and not sorted type by type.
Saint-Gobain Weber has now developed a solution: With the new zero waste external thermal insulation composite system weber.therm circle, all components can be separated according to type and recycled after dismantling.
From a one-time use of valuable resources, building thus develops into a raw material cycle. This future-proof premium system makes it possible to work in the highest quality and at the same time to plan and to build peak of ecological progress.
Robust, durable and recyclable
Many advantages in one system
weber.therm circle combines the advantages of all Weber ETICS. As a fully mineral thermal insulation composite system, it offers the high fire protection (class of reaction to fire A 1 - EN 13501-1) and is therefore non-combustible. The diffusion-open premium ETICS keeps the heat in the house in winter and in summer the heat outside. The massive construction scores with its high mass and good heat storage capacity. This favours rapid drying and thus prevents from algae growth. Due to the heavy mineral wool quality and the solid build-up the system also improves sound insulation.
With a solid render shell up to 25 mm thickness, weber.therm circle is also suitable for highly stressed facades. The solid render system is low-maintenance and its service life is significantly longer than that of a thin-layer system.
With AquaBalance mineral overlay renders (top coats) and AquaBalance paints the facade remains also protected against algae and fungi growth in the long term. The environment-friendly AquaBalance technology is based on a physical principle and require no biocidal additives. This protects the facade and the environment.
In addition to these advantages, weber.therm circle is the first external thermal insulation composite system to pursue the approach of recyclability in a consistent way. The system is mechanically fastened to the wall. A woven mesh as separation fabric embedded in the specially developed base coat render and the absence of bonding mortar ensures that it can later be completely dismantled and separated according to each component type. During the entire use phase weber.therm circle eets the same requirements for durability and safety as any other ETICS approved by the building authorities. Due to its design, it enables the components to be recycled and facilitates extensions and conversions as well as the integration of future technological leaps.
For this system the building authority approval under no. Z-33.9-167 been applied for.
One surface, unlimited possibilities
A high-quality wall construction deserves a worthy finish. After all, a technically demanding and permanently beautiful facade does not serve as a figurehead, but also contributes to the long-term preservation of the building value.
Mineral overlay renders do not only score points for their longevity, but also unfold a great depth effect. Variable render thicknesses give the facade an interesting and individual look.
The design options for mineral renders is almost unlimited. Thanks to a multitude of colour and texture combinations, every facade becomes unique. In addition to well-known textures, such as float renders, rilled renders or smooth renders, classic texturing techniques, like renders with broom or dragged textures are also available.
Solid and mineral
High-quality materials without biocides
weber.therm circle is not only convincing by its premium build-up and recyclability. With this top-class system, the use of a mineral AquaBalance scratch render provides a surface finish of highest quality.
From 2019, Weber equips its entire range of overlay renders (top coats) with biocide-free AquaBalance technology. It picks up the hydrophilic principle of mineral renders and reinforces it. The moisture is drawn off from the surface, stored in fine capillaries in the upper render layer and released in a controlled manner as temperatures rise. No moisture remains on the facade, and fungi and algae have no chance.
Thanks to its purely mineral components and the waiver of biocides, weber.therm circle contributes to a sustainable ecological lifestyle and meets the growing need for healthy living.
Pull it off once, please!
Clean separation and re-use after recycling
Circle of Life - from the life of an ETICS at some point every component reaches the end of its life. For the components of weber.therm circle, it's time to really get dismantled. Cleanly separated from each other, they become valuable resources and gain a new life.
The excavator shovel removes the render shell, which is divided into small fields, cleanly from the mineral wool, together with the separation fabric. Steel screws are screwed out of the wall and the dowel heads are cut with a milling cutter. Afterwards the mineral wool can be completely removed from the wall. Since all components can be easily separated from each other, the dismantling is done quickly. The dismantled components are collected separately and are re-used for a new purpose as single-variety raw materials.
provides conclusive answers to all questions about ETICS
- for cold, heat and sound insulation
- for safety in case of fire
- for algae prophylaxis, massiveness, freedom of design
- to the hitherto unresolved question of recyclability
