Product Overview
125mu (500G) (change with product size)Single Wound Screeding Membrane is a polyethylene barrier sheet designed to provide separation and moisture control beneath sand/cement or flowing screeds.
Its consistent thickness and flexible composition support clean laying across prepared substrates, reducing drag and preventing moisture migration into adjoining materials.
The membrane helps maintain a stable interface between the screed layer and underlying insulation or concrete, supporting predictable drying and surface integrity.
Its tear-resistant structure allows reliable unfolding and positioning during installation while accommodating irregularities in the substrate.
Supplied in 125mu (500G) thickness on a 2m × 100m roll, providing 200m² of membrane coverage.
Features & Benefits
- Moisture control: Helps resist moisture transfer between substrates and screeded layers.
- Separation barrier: Prevents bonding between screed and insulation or structural slabs where a slip layer is required.
- Durable sheeting: Resists tearing during handling, unfolding and placement.
- Clean installation: Single wound roll format supports efficient unrolling across large areas.
- Versatile use: Suitable for domestic and light-commercial screeded floors.
-
Roll identification: Supplied in 125mu (500G) thickness on a 2m × 100m roll providing 200m² coverage.
Applications
- Floating screeds: Suitable beneath sand/cement or flowing screeds over rigid insulation.
- Bonded or unbonded screeds: Functions as a separation layer to reduce adhesion or moisture interaction.
- Domestic and commercial floors: Appropriate for a wide range of screeded floor constructions.
- Refurbishment projects: Suitable where substrate isolation or moisture moderation is required.
Installation Guidance
- Substrate preparation: Ensure the base surface is clean and free from sharp debris that may puncture the membrane.
- Unrolling method: Roll out carefully over insulation or concrete, maintaining flat contact without creasing.
- Jointing: Overlap edges by the required distance and seal using approved membrane tape.
- Perimeter detailing: Turn up edges at walls to the required height to maintain continuity of the barrier.
- Important note: Avoid puncture damage and ensure continuity across the entire floor area.
Compliance & Performance
- Material classification: Manufactured from polyethylene suitable for use as a screeding separation membrane.
- Moisture resistance: Provides a controlled barrier reducing moisture interaction between screed and substrate.
- Durability: Maintains integrity when protected within the screed build-up.
- Handling note: Store in dry conditions and protect from direct sunlight prior to installation.
- Important note: Ensure compatibility with the screed type and floor build-up in accordance with installer guidance.
