Applications of Isolon 500 (roll, physically cross-linked IXPE)
Underlays, sealing tapes, HVAC, pipe insulation, pads and more.
Where to use Isolon 500 rolls and which thickness to choose
Typical roll range: 1–10 mm; AH grades are available up to 20 mm. Usual roll width 1.2–1.5 m.
| Application | Recom. thickness | Notes |
|---|---|---|
| Underlay for laminate / parquet | 2–3 mm | Reduces impact sound, adds resilience. Flat subfloor required, tape all joints. |
| Underlay for low-temp underfloor heating | 2–5 mm | For low-temperature systems; foil-faced grades are often used. Follow the heating system guidelines. |
| Interlayer pads / packaging | 1–5 mm | Layer separation, protection against scratches and light impacts. Can be slit into sheets and strips. |
| Sealing tapes / anti-squeak | 1–3 mm | Self-adhesive options simplify assembly; damping of joints and panel interfaces. |
| Acoustic underlay (floating floor) | 3–5 mm | Impact sound reduction; taped joints, no gaps or “bridges”. |
| Ducts (HVAC), panels | 5–10 мм | Thermal and vapour insulation; often with foil facing. Joints sealed with aluminium tape. |
| Pipe insulation (spiral wrapping) | 5–10 mm | 1–2 spiral layers; consider pipe diameter and operating conditions. |
| Construction underlays / separation layers | 3–8 mm | Compensates minor unevenness, decouples materials, moisture-resistant. |
Service temperature range: −60…+80/100 °C depending on grade (AH/AV). Detailed limits – see the Isolon 500 datasheet.
Objective: reduce footfall noise. Solution: Isolon 500, 3 mm with taped joints.
Result: quieter corridors and open areas with fast installation.
Rectangular ducts wrapped with 8 mm foil-faced Isolon 500. Reduced heat loss, clean appearance;
all joints sealed with aluminium tape.
Rolls slit into 2 mm tapes with acrylic PSA.
Result: parasitic squeaks between panels eliminated and assembly time reduced.
