1

Ductwork Insulation

Minimize heat loss or gain and prevent condensation in air ducts.

Application

Flexible Closed-Cell Rubber Foam: Install on both supply and return air ducts.

Benefits

Thermal Resistance: Maintains the temperature of the air as it travels through ducts, ensuring energy efficiency.


Condensation Prevention: Reduces the risk of moisture forming on ducts, preventing mold growth, and maintaining air quality.


Noise dampening: minimizes the sound of airflow within the ducts.


Recommended Material: NBR/PVC foam or EPDM rubber foam with a thickness range of 10-50 mm, depending on duct size and temperature differentials.

2

Refrigerant Pipe Insulation

Prevent heat transfer and condensation on refrigerant lines

Application

Insulated copper/aluminum pipes: to minimize energy loss and avoid condensation that could cause corrosion.

Benefits

Energy Efficiency: preserves the cooling or heating effect of the refrigerant by reducing heat transfer from the surroundings.


Prevention of Moisture Buildup: Avoids condensation, reducing the risk of corrosion, and extending the lifespan of the piping.


Recommended Material: Elastomeric foam with low thermal conductivity and vapor permeability.

3

Chiller and Cooling Tower Insulation

Enhance the thermal efficiency of chillers and cooling towers by preventing heat gain/loss.

Application

Rubber Foam Sheets: Apply on the external surfaces of chillers, cooling towers, and associated pipework.

Benefits

Reduced Heat Exchange: Keeps cold water cool for longer durations, ensuring more efficient chiller operation.


Moisture Barrier: Prevents water ingress and corrosion of equipment, lowering maintenance costs.


Recommended Material: UV-resistant rubber foam with an operating temperature range suitable for outdoor exposure (e.g., EPDM foam).

4

HVAC Equipment Housing Insulation

Improve energy efficiency and reduce noise from HVAC equipment like air handlers and heat pumps.

Application

Rubber Foam Panels or Rolls: Install inside HVAC unit casings, compressors, or air handlers.

Benefits

Thermal Insulation: Enhances the overall efficiency of the system by reducing thermal losses.


Noise Reduction: Reduces operational noise, providing quieter performance for buildings.


Recommended Material: Flexible rubber foam with high sound-absorbing properties and moderate thickness to fit within equipment housing.

5

Sound Attenuation

Reduce vibration and noise transmission in HVAC systems.

Application

Vibration Dampening Pads or Sheets: Place rubber foam insulation around fans, compressors, and between metal components.

Benefits

Noise Reduction: Minimizes vibration and sound transmission through ductwork and mechanical units.


Enhanced Comfort: Provides quieter indoor environments by reducing operational noise.


Recommended Material: High-density rubber foam with sound-absorbing and anti-vibration properties.

6

Fire Safety

Enhance safety by using fire-retardant insulation materials.

Application

Fire-Resistant Rubber Foam: Use rubber foam with fire-resistant properties in HVAC systems, especially in areas with strict fire safety 

Benefits

Flame Retardancy: Limits the spread of flames in the event of a fire, contributing to building safety.


Compliance: Ensures compliance with local fire safety standards and regulations.
Recommended Material: Fire-resistant rubber foam with certifications for flame and smoke

7

Indoor Air Quality and Mold Prevention

Mitigate mold growth and protect indoor air quality by controlling condensation and moisture.

Application

Moisture-Resistant Rubber Foam: Use rubber foam insulation on pipes and ductwork in humid environments such as basements, near cooling units, and in areas prone to temperature fluctuations.

Benefits

Mold Prevention: By preventing condensation, rubber foam insulation reduces the risk of mold growth, protecting indoor air quality.


Corrosion Control: Prevents moisture buildup that can lead to rust and deterioration of metal components.


Recommended Material: Closed-cell rubber foam with antimicrobial additives or moisture-resistant coatings.
