Why choose Light-Weight Filler? The value of Light-Weight Filler technology compared to conventional fillers.
At Clades Composites, we continue to focus on sustainable R&D. Our Light-Weight Filler technology represents a paradigm shift for the composite materials industry. The reason? We have developed a 100% recycled mineral filler that significantly reduces the weight of final products without compromising their technical properties.
Lighter, more competitive.
One of the greatest advantages of Light Filler is the reduction in the final weight of the product. For example, a 1200 x 900 mm resin shower tray that normally weighs 38.5 kg can be reduced to just 28.5 kg, a saving of nearly 30%. This difference translates into:
- Reduced logistics and transportation costs
- Easier assembly and installation
- Better factory handling
- Significant increase in productivity
Our customers report production increases of up to 25-35% using the Light-Weight Filler.
Sustainability without compromising performance.
In addition to being lighter, our light-weight fillers are composed of 100% recycled materials. This solution not only reduces the environmental impact but also aligns with current market demands regarding ecological responsibility.
The technology has been validated by independent laboratories in accordance with EU regulations and is already present in thousands of products, including shower trays, countertops, bathtubs, ventilated facades, balustrades, and more.


Easy implementation and adaptable to every need.
Another major advantage of our technology is its easy integration into existing production lines. It does not require large investments, making it an ideal option for both established companies and those just starting out in the sector. The standard formulation includes:
- 30-35% resin
- 65-70% low-weight filler (LWF)
- 1.5% peroxide as a catalyst
- ISO-NPG gel coat finish
We manufacture Low Weight Fillers in different densities to suit each client’s needs:
- BP-140
- BP-130
- BP-120
- BP-100
- BP-090
- *Concentrated Filler
*To further optimize logistics costs, we have developed a concentrated version of our filler, which can be blended with local mineral fillers. This reduces shipping volume without sacrificing functionality and quality, making it especially useful in international projects.
Therefore, the Low Weight Filler is much more than a simple filler; it is an improved, sustainable, and cost-effective solution that is already making a difference in the composites industry.
