Its fine closed-cell structure provides low thermal conductivity, moisture resistance and good cushioning performance. Supplied in rolls and sheets in various thicknesses, with optional lamination and self-adhesive backing. Production and quality control comply with TU 2244-037-00203476-2012.
Density 25–200 kg/m³
Temperature −60…+80 °C
Environmentally friendly, safe material
Thickness 4–50 mm
Sound insulation: up to 25 dB
Water absorption: ≤ 3 % by volume
Important information
A quality certificate for the material is available for customers on request. To issue the certificate, please specify the batch number as shown on the roll or sheet label.
On request we can also provide:
- certificates and declarations;
- accompanying shipping and product documentation;
- statements on the regulatory status of the product (e.g. exemption from mandatory certification, where applicable).
Technical specifications (TU) are provided only for products purchased from our company.
The material has previously been manufactured under earlier revisions of the same technical specification. Archived documentation can be supplied on request if needed.

Applications of Isolon 300 (chemically cross-linked PE foam)
Underlays, pads, HVAC, pipe insulation, sealing and more.
Where to use Isolon 300 and which thickness to choose
Roll-form chemically cross-linked PE foam (4–10 mm). For boards / mats >10 mm use the sheet range (Isolon 300 sheets).
| Application | Recommended thickness | Notes |
|---|---|---|
| Laminate / parquet underlay | 4–5 mm | Reduces impact noise, adds resilience. Requires a flat base; joints should be taped. |
| Underlay for low-temperature underfloor heating | 4–5 mm | For low-temperature systems. Foil-faced / perforated grades are possible; follow the system supplier’s guidelines. |
| Interlayer pads / packaging | 4–8 mm | Separating layers, protection against scratches and impacts. Cut to sheets or tapes. |
| Sealing tapes / anti-squeak | 4–5 mm (slit rolls) | Slitting from roll into tapes; optional self-adhesive layer (acrylic adhesive). |
| Acoustic underlay (floating floor) | 4–5 mm | Reduces impact noise. Tape joints and avoid rigid “bridges”. |
| Air ducts (HVAC), panels | 5–10 mm | Thermal / vapour insulation, often foil-faced. Seal joints with aluminium tape. |
| Pipe insulation (wrap-around) | 5–10 mm | Spiral wrapping in 1–2 layers, fixed with tapes; thickness depends on pipe diameter and service conditions. |
For 1–3 mm thickness other product ranges / grades are usually used. Standard roll thicknesses for Isolon 300 are 4–10 mm.
Task: reduce impact noise and speed up installation. Solution: Isolon 300 4 mm with taped joints. Result: quieter stairwells and corridors, faster installation.
Wrapping round and rectangular ducts with Isolon 300 8 mm (LA/LM). Reduced heat losses and a neat appearance; joints sealed with aluminium tape.
Slitting 5 mm rolls into tapes with acrylic adhesive. Result: eliminated panel squeaks and parasitic vibrations, reduced customer complaints.
