Parquet board underlay ( Polyethylene foam PE )
Price range: €62.00 through €248.00
PE is a heat and sound insulating material made of polyethylene foam chemically cross-linked with a closed cell structure, which does not allow moisture to pass through. Due to cross-linking, the material has a molecular structure with a cross-linked or mesh model, which significantly increases its resistance to mechanical and temperature effects. The canvas has a low percentage of residual deformation and low hygroscopicity. The material is resistant to distributed loads, restores sizes well after removal of the load. Easily cut with a knife, water jet, vibrating knife. Laser cutting, thermoforming, stamping can be used for processing.

Advantages of polyethylene foam
- PE has good thermal insulation properties;
- Creates acoustic comfort;
- Reduces vibration levels;
- Hydraulic and steam barrier – does not allow moisture and steam to pass through;
- Stable structure – high tensile strength and deformation strength;
- Maintains stable properties over time under high statistical and dynamic loads;
- Environmentally friendly material – does not contain substances hazardous to health and the environment;
- PE is resistant to aggressive environments, petrol, oils, cement sand mortars, atmospheric effects;
- The closed cell foam construction provides excellent insulation and acoustic properties;
- Polyethylene foam does not promote the growth of fungi and bacteria;
- PE has high quality, manufactured on high-tech equipment in accordance with international standards and ISO requirements.
Application in building
- Thermal and acoustic insulation of interior and exterior walls;
- Thermal and sound insulation of floor ceilings, insulation of wooden floors, soundproof membrane under the screed;
