What is WedGel™ Aerogel Felt and how is it different from conventional insulation?

It’s a silica-aerogel composite felt that delivers high thermal resistance at a fraction of the thickness of mineral wool or calcium silicate. It’s thin, flexible, hydrophobic, and easy to wrap around pipes, ducts, doors, and panels.

Which grade should I choose (WAG 650 / CAC 350 / CRYO 200)?

Use WAG 650 for hot pipes, ducts, and jackets (up to ~650 °C), CAC 350 for thermal + passive fire barriers (continuous to ~350 °C), and CRYO 200 for cold/cryogenic service (about −200 to +200 °C).

What thickness do I need?

Thickness depends on line temperature, ambient, target surface temperature, airflow, and cladding. Hot lines often use 5–15 mm per layer; cryogenic builds typically use multi-layers with staggered seams.

Is it water-repellent? Do I still need cladding outdoors?

Yes—WedGel is hydrophobic yet breathable. For outdoor or washdown areas, use metal cladding to protect against weather and mechanical damage.

Which facing is best for my application?

Aluminium foil for a neat, reflective finish; fiberglass or silica cloth for high-abuse/high-temperature jackets; PE film for clean-room or cold service. Choose facing by fire, hygiene, and finish needs.

How do I install it, and can I compress it?

Cut with a knife/shears, wrap, and secure using SS bands/wire or high-temp tape (per facing). Stagger seams for multi-layers and avoid over-compression to preserve k-value.

Can you supply pre-cut kits or custom die-cuts?

Yes. We provide pre-cut kits for ducts, doors, battery modules, and OEM parts based on your drawings or cut lists.

What are the typical thermal conductivity values across temperature?

At 25 °C, k is typically 0.017–0.021 W/m·K (grade-dependent). k increases with temperature; at ~200 °C, typical values are ~0.024–0.028 W/m·K.

What sizes and packaging are available?

Standard thickness 3–25 mm (laminations up to 50 mm), widths 1000/1200/1500 mm. Roll-length guide: 3 mm ≈ 30 m, 5 mm ≈ 20 m, 10 mm ≈ 10 m.

What about compliance, HS Code, and safety?

Manufactured under ISO 9001; test reports to ASTM/EN are available on request. Indicative HS Codes: 560290 / 680690 (final depends on grade/facing and jurisdiction). Use PPE (gloves, sleeves, goggles); vacuum dust and dispose per local regulations.
