Proper installation is critical to achieving the full thermal, mechanical, and moisture-resistance benefits of aerogel insulation. Because aerogel blankets are thin and high-performance, small installation errors (over-compression, gaps, poor sealing) can significantly affect long-term results.

Below is a practical, field-oriented guide for industrial applications.

1️⃣ Pre-Installation Preparation

✔ Surface Inspection

• Ensure equipment is clean, dry, and free of oil or debris.
• Repair damaged coatings.
• Verify corrosion protection system compatibility.

✔ Confirm Design Thickness

Before installation:

• Verify required thickness per thermal calculation.
• Confirm number of layers.
• Review drawings and insulation specification.

✔ Check Environmental Conditions

• Avoid installation during heavy rain (unless temporary protection is provided).
• Ensure storage area is dry and elevated.

2️⃣ Cutting & Handling

Aerogel blankets are flexible but should be handled carefully.

Tools Required

• Sharp utility knife
• Straight edge or cutting guide
• Measuring tape
• PPE (gloves, dust mask, eye protection)

Best Practices

• Cut on a flat surface.
• Avoid excessive tearing.
• Minimize dust generation.
• Do not compress material while cutting.

3️⃣ Installation on Piping

Step-by-Step

1. Wrap blanket around pipe with tight surface contact.
2. Maintain consistent overlap (typically 25–50 mm).
3. Install in multiple layers if required.
4. Stagger seams between layers.
5. Secure with stainless steel bands or wire.

Important:

Avoid excessive compression.

Thermal resistance depends on thickness:

If thickness (L) decreases due to over-tight banding, thermal performance drops.

4️⃣ Installation on Vessels & Tanks

Flat or Large Surfaces

• Apply blanket in vertical or horizontal runs.
• Use insulation pins if required.
• Ensure tight butt joints (no gaps).
• Tape seams if specified.

Curved or Irregular Surfaces

• Pre-cut sections to minimize wrinkling.
• Use radial segmentation for domed ends.
• Avoid folding or creasing excessively.

5️⃣ Multi-Layer Installation Strategy

For higher thickness requirements:

✔ Install in 2–3 layers instead of one thick layer
✔ Stagger joints between layers
✔ Ensure full surface coverage

Benefits:

• Reduces thermal bridging
• Improves mechanical stability
• Enhances long-term performance

6️⃣ Moisture Management

Although aerogel blankets are typically hydrophobic:

• They are not waterproof systems by themselves.
• Always install proper vapor barriers when required.
• Apply metal jacketing for outdoor or exposed systems.
• Seal all cladding seams properly.

For steam systems, moisture control is critical to reduce corrosion under insulation (CUI).

7️⃣ Mechanical Protection & Cladding

Aerogel blankets require external protection:

Common Cladding Materials

• Aluminum sheet
• Stainless steel sheet
• Galvanized steel

Installation Tips

• Avoid over-tightening cladding bands.
• Allow for thermal expansion.
• Ensure drain paths where required.
• Maintain proper support spacing.

8️⃣ Expansion Joints & High-Vibration Areas

In areas such as:

• Turbines
• Compressors
• Pump lines

Best practices:

✔ Use flexible wrapping technique
✔ Allow slight movement tolerance
✔ Avoid rigid bonding
✔ Inspect periodically

Aerogel’s flexibility helps resist cracking under vibration.

9️⃣ Avoiding Common Installation Mistakes

❌ Over-compressing insulation
❌ Leaving gaps at seams
❌ Misaligned multi-layer joints
❌ Installing wet material
❌ Skipping cladding protection
❌ Ignoring pipe supports and penetration details

🔟 Quality Inspection Checklist

After installation, verify:

✔ Correct thickness installed
✔ No visible compression damage
✔ Seams properly overlapped
✔ Bands properly spaced
✔ Cladding secured but not crushing insulation
✔ All penetrations sealed

1️⃣1️⃣ Safety Considerations

• Wear gloves (fibrous reinforcement may irritate skin).
• Use dust mask when cutting.
• Follow site safety standards.
• Dispose of scraps according to regulations.

Final Takeaway

To maximize aerogel blanket performance in industrial applications:

✔ Maintain design thickness
✔ Avoid compression
✔ Use multi-layer staggered installation
✔ Protect with proper cladding
✔ Manage moisture carefully
✔ Inspect thoroughly after installation

Correct installation ensures:

• Maximum thermal efficiency
• Long service life
• Reduced maintenance
• Lower total lifecycle cost
