⚠️ READ! BEWARE OF DECEPTIVE PRACTICES
Some unscrupulous sellers offer recycled graphite beads without specifying it, and even go as far as announcing a false lambda coefficient, often much better than reality.
Result: the buyer thinks they are insulating effectively, but gets a much lower performance, without knowing it.
With Pure Graphite beads, we guarantee 100% new beads, with a real lambda of 0.030 to 0.033 W/m·K.
✅ New Pure Graphite Balls
Perfectly round and homogeneous, the new Pure Graphite balls retain all their insulating properties. They provide optimal thermal insulation, thanks to their complete structure that traps air.
❌ Recycled graphite marbles
Often broken or cut in half, recycled graphite polystyrene marbles lose all their insulating performance. Their irregular shape reduces the amount of trapped air, so the insulation is less effective.
Pure Graphite – The high-performance insulation solution
The new graphitized polystyrene beads from the Pure Graphite brand offer a reliable, durable, and high-performing thermal and acoustic insulation solution.
Benefits of Pure Graphite Beads
- Excellent thermal performance: lambda between 0.030 and 0.033 W/m·K
- New material: consistent quality, not recycled
- Versatility of use: hollow walls, attics, partitions, floors...
- Resistance to moisture: prevents condensation and mold
- Acoustic comfort: reduction of ambient noise
Recommended Applications
- Thermal and acoustic insulation: hollow walls, lost attics, partitions, floors
- Against moisture: under-slab, crawl spaces
- Comfort & energy savings: in-ground pools, roofs, cellars, basements
Use our polystyrene bead blower, it's the ideal tool for injecting polystyrene beads into walls.
