Why Choose Aerogel Felt?

Aerogel Thermal Insulation Felt offers ultra-low thermal conductivity, excellent temperature stability, and superior space-saving performance compared with conventional options like PU tile, glass wool shell, and aluminum silicate fiber felt. It is lightweight, highly flexible, and easy to conform to curved surfaces - ideal for pipeline insulation where efficiency and minimal thickness matter.

Tools and Materials You'll Need

Before you begin, gather these items to ensure a smooth installation:

• Aerogel Thermal Insulation Felt (correct thickness and roll size for your application)
• Sharp utility knife or insulation cutter
• Measuring tape and marker
• Suitable adhesive (use high-temperature adhesive for hot pipelines)
• Roller or flat pressing tool
• Sealant compatible with aerogel insulation (silicone or specialized sealant)
• Safety gear: gloves, safety glasses, and dust mask

Step 1 - Prepare the Pipeline Surface

Proper surface preparation is essential for long-term adhesion:

• Ensure the pipe surface is clean, dry, and free of oil, dust, and loose rust.
• Remove any scale or flaking paint. For rough areas, lightly sand to create a smoother substrate.
• If the pipe is wet or sweating, address the moisture issue before applying insulation.

Step 2 - Measure and Cut the Aerogel Felt

Measure carefully to avoid waste and ensure a snug fit:

• Record the pipeline circumference and the length of the section to be insulated.
• Mark the measurements on the aerogel felt and cut with a sharp knife for clean edges.
• For elbows or irregular shapes, add small V-cuts or overlaps so the material wraps without gaps.

Step 3 - Apply the Adhesive

Choose an adhesive compatible with aerogel and the pipe's service temperature.

• Apply adhesive to the back of the felt or directly onto the pipe according to adhesive instructions.
• Spread evenly with a brush for paste adhesives, or follow spray adhesive directions if using aerosol products.
• Ensure even coverage - missed spots can create cold bridges or loose sections later.

Step 4 - Install the Aerogel Felt

Work methodically for a smooth, gap-free layer:

1. Begin at one end of the pipe and position the felt carefully.
2. Wrap and press the felt down while smoothing out air bubbles.
3. Align edges of adjacent pieces closely - where overlaps are required, do so consistently to maintain thickness.
4. Use a roller or flat tool to apply uniform pressure, ensuring good adhesive contact.

Step 5 - Seal the Edges

Sealing prevents moisture and air ingress that reduce performance:

• Apply a compatible sealant along seams and terminations using a caulking gun or brush.
• Pay special attention to joints near flanges, valves and supports

Step 6 - Final Inspection

Inspect the installation to catch issues before commissioning:

• Look for loose edges, gaps, or bubbles.
• Re-apply adhesive or add small filler pieces where gaps exist.
• Confirm that all seams are sealed and that there are no exposed areas.

Maintenance

Aerogel Thermal Insulation Felt is low-maintenance but requires basic care:

• Avoid sharp impacts or punctures.
• Clean surface dust gently with a soft brush or damp cloth (do not soak).
• Inspect periodically, especially in high-traffic areas or where mechanical damage is possible.

Troubleshooting

Common issues and quick remedies:

• Adhesive not sticking: Re-clean surface and use a recommended high-temperature or specialist adhesive.
• Wrinkles or air bubbles: Smooth with a roller while adhesive is tacky; use low heat to increase flexibility if manufacturer allows.
• Gaps or misalignment: Cut filler strips from leftover material and secure with adhesive and sealant.
