Intelmann® Insulation Mat / Insulation Mat, self-adhesive – Insulation thickness 13 / 19 / 25 mmThe Intelmann® insulation mat made of elastomeric soft foam (FEF) is the professional solution for thermal insulation, cold insulation and condensation prevention in ventilation, air conditioning and piping systems. Thanks to the closed-cell structure, it offers excellent insulation performance and reliably protects against energy loss and moisture ingress.The self-adhesive version allows for quick, clean and secure installation without additional adhesive. Due to its high flexibility, the insulation mat can be optimally adapted to different shapes and surfaces – ideal for pipes, ducts and technical equipment.With a very good thermal conductivity of 0.034 to 0.037 W/(m·K) as well as a high water vapour resistance (≥ 10,000 µ), the insulation mat ensures effective insulation and reliably prevents condensation formation. In addition, it meets the fire protection class B-s3, d0 and is self-extinguishing.Advantages at a glance:✅ Excellent insulation performance – Reduces heat loss and energy consumption✅ Self-adhesive – Fast and easy processing without additional glue✅ Closed-cell – Very good moisture and vapour barrier✅ Flexible & adaptable – Ideal for pipes, ducts and surfaces✅ Fire protection compliant – Class B-s3, d0, self-extinguishing✅ Hygienic – No bacterial or fungal growthTechnical details:✔ Product name: Intelmann® Insulation Mat / Insulation Mat✔ Material: Elastomeric soft foam (FEF)✔ Cell structure: Closed✔ Insulation thicknesses: 13 / 19 / 25 mm✔ Roll dimensions: • 13 mm: 10 m x 1 m • 19 mm: 7 m x 1 m • 25 mm: 5 m x 1 m✔ Colour: Black / Anthracite✔ Temperature range: -50 °C to +85 °C✔ Thermal conductivity: 0.034 – 0.037 W/(m·K)✔ Water vapour resistance: ≥ 10,000 µ✔ Fire protection class: B-s3, d0✔ Fire behaviour: Self-extinguishing, no droplets, no flame spreadTypical areas of application:The insulation mat is ideal for insulating ventilation ducts, pipelines, air conditioning and refrigeration systems. It reduces heat loss, prevents condensation and improves the energy efficiency of technical systems. It is also used in plant construction and industrial applications for thermal and acoustic insulation.Installation instructions:For optimal adhesion, the surface should be clean, dry and free of grease. The mat is cut to size, the protective film removed and then pressed down evenly. Overlaps and joints can be additionally sealed with suitable adhesive tape to ensure continuous insulation.With the Intelmann® insulation mat, you receive a powerful, durable and installation-friendly solution for professional insulation and insulating work.
