Seal Your Duct Leaks Without Major Disruption
Aeroseal duct sealing is an advanced solution that seals air leaks within duct systems from the inside, helping improve airflow performance, reduce energy loss, and support better indoor air distribution across your building.
- No duct replacement
- Measurable energy savings
- Fast, non-disruptive process
- Proven globally
Award


The Singapore Green Plan 2030 is a nationwide initiative driving the country’s long-term sustainable development goals.
AeroSeal duct sealing supports this vision by reducing energy loss in HVAC systems, improving building efficiency, and contributing to Singapore’s broader efforts to lower carbon emissions.

Why AeroSeal® Duct Sealing?

Seals duct leaks from the inside using patented Aeroseal technology.

Injects specialised sealant particles that automatically locate and seal air leaks.

Improves duct performance without extensive dismantling or major disruption.
How Aeroseal Duct Sealing Works?

1. System Preparation
The duct system is temporarily sealed and connected to the Aeroseal equipment.

2. Leak Detection

3. Internal Sealing

4. Verification

NeoCOAT vs Conventional Heat Reflective Paint
over 25∘C

NeoCOAT dissipates thermal energy within the paint by transforming heat into kinetic energy.
Conventional heat reflective paint reflects IR (infrared rays), creating an urban heat island.
surface with dirt

Surface dirt does not influence heat exchange. Thus, the temperature underneath is lowered. Heat reflection fails with surface dirt and the temperature goes up.
Real-World Proven Performance
NeoCOAT systems have been tested across roofs and facilities in Japan, showing significant reductions in surface temperature and improved durability under strong sun and heat exposure.


Before coating with NeoCOAT: average temperature of 47.8℃.

After coating with NeoCOAT: average temperature of 37.2℃.

Where can NeoCOAT be Used?

Exterior wall (D-47)
NeoCOAT D-47 strengthens exterior wall protection against heat, moisture, and UV damage. It reduces paint peeling, enhances energy efficiency, and maintains long-term façade quality.

Waterproof roof (D-42)
Designed for waterproofed rooftops, NeoCOAT D-42 enhances weather resistance, minimises surface cracking, and maintains long-term coating stability under harsh sun and rain.

Tin roof (D-42)
NeoCOAT D-42 provides durable protection for tin roofs by reducing heat absorption and preventing surface deterioration. Ideal for improving comfort and extending roof lifespan in high-exposure areas.

Playground Equipment (D-42)
Suitable for metal and coated playground structures, NeoCOAT D-42 helps prevent overheating, reduces UV damage, and maintains vibrant, safe surfaces for public spaces.

Poolside (D-47)
Perfect for humid and water-exposed zones, NeoCOAT D-47 prevents mould growth, cracking, and fading, ensuring cooler, slip-resistant, and visually consistent poolside surfaces.

Manufacturing and Industrial Facilities

Bridge (D-47)
NeoCOAT D-47 protects bridge surfaces by minimising thermal stress, improving durability, and providing strong resistance against environmental wear and moisture infiltration.

Elementary school (D-47)
Applied on school buildings and high-contact areas, NeoCOAT D-47 helps maintain clean, cooler surfaces and prevents early degradation, supporting safer, longer-lasting environments.

Commercial Kitchens and Food Processing Areas
NeoCOAT resists heat, grease, and cleaning chemicals, making it ideal for kitchen walls, ceilings, prep rooms, and storage zones where hygiene is critical

Healthcare and Clinical Environments
Used in clinics, diagnostics labs, and consultation rooms, NeoCOAT helps maintain sterile conditions by preventing microbial buildup on wall and ceiling surfaces
