Thermal & Acoustic Sealing

Foam Insulation Tapes

Closed-cell PE foam and polyurethane foam tapes with high-tack adhesive for weather sealing, thermal insulation, and acoustic damping in construction, automotive, and industrial applications.

Product Overview

Seal, Insulate & Dampen Noise

Practak foam insulation tapes combine closed-cell polyethylene or polyurethane foam with a high-tack acrylic PSA to deliver reliable sealing against air, water, dust, and noise. The compression-recovery properties ensure a long-term, leak-free seal even after repeated opening and closing cycles. Available in single-sided and double-sided configurations across a wide range of thicknesses and widths for HVAC, construction, automotive, and appliance manufacturing.

Material: Closed-cell PE foam / polyurethane foam

Thickness: 3 mm · 5 mm · 8 mm · 10 mm · 15 mm

Adhesive: High-tack acrylic PSA (single or double-sided)

Temperature range: -30 °C to +80 °C

Features & Benefits

Weather Sealing

Creates an effective barrier against wind, rain, dust, and insects around doors, windows, and panel joints.

Thermal Insulation

Low thermal conductivity (0.040 W/m·K) reduces heat transfer across gaps and joints, improving energy efficiency in buildings and vehicles.

Acoustic Damping

Noise Reduction Coefficient (NRC) of 0.25–0.45 absorbs airborne noise and reduces structure-borne vibration in machinery and vehicles.

High Compression Recovery

Recovers ≥ 80% of its original thickness after 24 hours of sustained compression, maintaining a reliable long-term seal.

Easy Installation

Flexible foam cuts cleanly with scissors or a knife. Peel-and-stick adhesive ensures fast, repositionable installation without tools.

Chemical Resistance

Closed-cell structure resists moisture absorption, common solvents, dilute acids, and alkalis — suitable for harsh industrial environments.
