⚠️ READ THIS! BEWARE OF MISLEADING PRACTICES
Some unscrupulous sellers offer recycled graphite beads without specifying it, and even go as far as announcing a fake 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 uniform, 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 – High Performance Insulation Solution
The brand new graphited polystyrene beads from Pure Graphite offer an efficient, reliable and long-lasting 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...
- Moisture resistance: prevents condensation and mould
- Acoustic comfort: reduction of ambient noises
Recommended Applications
- Thermal and acoustic insulation: hollow walls, lost attics, partitions, floors
- Against moisture: under slab, crawl spaces
- Comfort & energy savings: underground pools, roofs, cellars, basements
Use our polystyrene bead blower, it's the ideal tool for injecting polystyrene beads into the walls.
