Features
- Made from red, closed-cell, cross-linked polyethylene foam (three-dimensional structure).
- Transparent LDPE protective film 45 microns thick.
Advantages
- Excellent mechanical strength.
- Excellent chemical and thermal resistance.
- Excellent flexibility.
- Minimum water absorption values.
- Very low permeability to water vapour.
- Very weather-resistant.
- Chemically inert and non-polluting.
- Quick and easy installation.
- The protective film improves tear and puncture resistance, and waterproofing.
These instructions are merely recommendations based on our experience. We recommend performing tests for each new type of application or surface to be treated.
Datasheets(X)
Can be applied horizontally on concrete, mortar, flooring blocks etc.
Sound insulation against impact noise and domestic noise, such as moving furniture, dropped items and noisy shoes.
Can be applied on slab and under mortar screeds.
The substrate must be clean, firm, smooth and dry, free from loose particles and other sharp materials that may damage the sheet.
Unroll the sheet onto the substrate so the film is facing upwards, avoiding folds and irregularities.
Cut the sheet as required to avoid any obstacles (pillars, pipes etc.).
Leave around 10 cm of excess sheet at joints with partitions. Cut off the excess sheet once the mortar (approx. 5 cm) and the final flooring (decking, stoneware, parquet etc.) have been incorporated.
Overlap by 10 cm and seal with adhesive tape if required.
