Description
EPDM Tape – EPDM Resilient Building Tape (Waterproof & Acoustic Grade)
EPDM tape is a flexible, closed-cell rubber sealing strip designed for waterproofing, glazing and construction applications. Manufactured from 120kg density EPDM foam, this tape delivers exceptional durability, anti-vibration performance, and sound dampening capability. Each roll is supplied with an acrylic adhesive on one side, making installation fast, secure, and suitable for a wide range of surfaces.
This resilient EPDM tape is widely used in construction to reduce sound transfer between partitions, frames, and joints, helping improve both acoustic performance and overall structural stability. In addition to its acoustic benefits, EPDM offers waterproofing, thermal stability, and electrical resistivity, making it suitable for electrical, industrial, and automotive environments where long-term performance is essential.
Who is this EPDM Resilient Tape for?
- Dryliners installing resilient bar systems
- Builders reducing sound transfer between walls
- Contractors working on timber framing & partitions
- Anyone needing acoustic isolation + sealing in construction
For larger sealing applications, explore our EPDM sponge rubber sheets which offer similar waterproofing and compression performance in sheet form.
EPDM Resilient Tape vs Foam Tape
Unlike standard foam tapes, EPDM resilient tape offers significantly higher density (120kg/m³), improving both acoustic isolation and long-term durability. It is specifically designed for structural applications where vibration reduction and sound control are critical.

Comparison Chart (EPDM Tape vs Alternatives)
| Feature | EPDM Tape (This Product) | Butyl Tape | Standard Foam Tape |
|---|---|---|---|
| Waterproof | ✔ Excellent | ✔ Good | ✖ Low |
| Acoustic performance | ✔ High | ✔ Medium | ✖ Low |
| Vibration damping | ✔ High | ✔ Medium | ✖ Low |
| Density | 120kg/m³ | Medium | Low |
| Adhesive strength | ✔ Strong | ✔ Strong | Medium |
| Temperature resistance | ✔ –30°C to +80°C | Good | Poor |
| Longevity | ✔ Excellent | Good | Poor |
| Ideal for | Construction, structural joints, acoustic work | Roofing, general sealing | Light domestic use |
For roofing and lap joint sealing, you may also want to consider our butyl tape range, which is better suited to non-structural waterproof sealing applications.
How to Apply EPDM Tape
- Prepare the surface: clean, dry, and free from dust or grease. Use isopropyl alcohol (IPA) for degreasing. Prime porous surfaces if needed.
- Measure & cut: cut to length with a sharp knife or scissors.
- Peel & apply: peel back the release liner gradually while pressing the tape firmly into place.
- Press down: use firm pressure or a roller to ensure full contact and remove air bubbles.
- Finish: check edges are secure; full bond strength develops within 24 hours.
Conclusion
EPDM resilient tape is a reliable, long-lasting solution for acoustic isolation, vibration control and waterproof sealing in construction and industrial applications.
With its high-density closed-cell structure, strong adhesion and excellent durability, this EPDM tape is ideal for use in walls, floors, timber framing and structural joints where performance matters.
Whether you’re a builder, dryliner or contractor, choosing the right resilient tape can make a significant difference to both sound reduction and long-term structural integrity.
