Welcome to your comprehensive guide on installing high-performance insulation with Bostik T303 Class 0 Foil Tape. This guide is designed for professionals in residential, commercial, and industrial settings, ensuring a smooth and efficient installation process. Follow these steps to ensure optimal performance and energy efficiency.


Before any installation, the importance of a clean and dry surface cannot be overstated. Start by thoroughly inspecting your pipes or surfaces for any debris, dust, or moisture. Clean off any contaminants to ensure the adhesive bonds effectively. Measure the lengths of the pipes accurately, as precise measurements are crucial for the next steps.

Cutting to Size

Using a fine-tooth saw or a sharp knife, cut the insulation material to the required size. Precision is key, so measure and mark your insulation before making any cuts. This ensures a perfect fit around your pipes or surfaces, minimizing waste and ensuring efficient use of materials.

Applying Insulation

Open the insulation material along its slit side and carefully place it around the pipe. It's essential to ensure a snug fit to prevent thermal bridging—a phenomenon that can significantly reduce the insulation's effectiveness. Adjust as necessary to achieve a uniform wrap around the surface.

Securing Insulation

Now, use Bostik T303 Class 0 Foil Tape to secure the seams of the insulation sections. This step is crucial for maximizing the insulation's efficiency, creating a continuous barrier that enhances thermal performance. Ensure that all joints are tightly sealed with the tape, pressing firmly for optimal adhesion.

Finishing Touches

In areas exposed to moisture or outdoor conditions, it's vital to apply a waterproof finish or cladding over the insulation. This protects the insulation from environmental damage and extends its lifespan, maintaining its performance over time.
