Envirco Vinyl Sheets

Envirco Vinyl Sheets

ENVIRCO Vinyl Sheets is a polymer-based, bitumen-free, high-density synthetic membrane. The combination of its viscoelasticity and high density offers excellent sound insulation in various construction elements without increasing thickness. The upper face is finished with non-woven polypropylene, providing mechanical properties as well as protection. The lower face is finished with PE film.

ADVANTAGES

1. High sound insulation combined with light and rigid elements such as gypsum boards.
2. High sound damping capacity on metal surfaces, improving insulation against rainfall noise on metal decks.
3. Classified for reaction to fire.
4. Flexible and adaptable to uneven surfaces.
5. Performs well at low temperatures without breaking or cracking.
6. Easy to handle and cut with a knife or scissors.
7. May function as a vapor control layer.
8. Negligible water absorption.
9. Aging resistance.
10. Rot-proof.

Specifications

1. Increases airborne noise insulation on vertical surfaces with low surface mass (e.g., plasterboard and timber partitions).
2. Provides soundproofing against airborne noise in ceilings and lightweight roofs.
3. Reduces drumming noise levels in laminated floors.
4. Dampens noise caused by weathering, such as rain and hail on metal deck roofs.
5. When combined with sound-absorbent materials, it offers solutions with high acoustic performance.
6. Its industrial applications range from soundproofing booths to acoustic insulation in machine rooms, engine cowlings, gutter pipes, and sound damping of metal sheets.

Regulations

Laboratory test reports are available according to EN ISO 140-1, EN ISO 140-3, EN ISO 140-6, EN ISO 140-8, EN ISO 10140, and EN ISO 717/1/2.

Installation

1. Substrate: The substrate must be even, smooth, clean, and dry. It must also be free from elements that could damage the membrane. If the rendering is old, its condition must be checked to avoid adherence problems of the ENVIRCO sheet to the rendering.

2. Installation of the Membrane on Metal Decks: Extend the roll over the substrate progressively, with the fleece side facing upwards, and ensure an overlap of at least 5 cm. If installing directly on top of the steel deck, the membrane should be applied perpendicular to the direction of the deck profile. In the case of mechanically fixed insulation and waterproofing systems, the specifications for the type and number of fasteners needed must be respected.
