HVAC Insulation Solutions for Ducts, Pipes and Equipment

FUNAS supplies insulation materials for HVAC ducts, chilled water and refrigerant piping, air handling equipment and related mechanical systems. Available options include rubber foam pipes and sheets, glass wool and rock wool products for different thermal, condensation, acoustic and fire-performance requirements.

Refrigerant and Chilled Water Pipe Insulation

Closed-cell rubber foam pipe or sheet may be used on below-ambient piping where heat gain and surface condensation need to be controlled. Product selection should be based on pipe outside diameter, operating temperature, ambient humidity, required insulation thickness and installation conditions.

HVAC Duct Insulation

Rubber foam sheet, glass wool board or glass wool roll may be considered for rectangular and circular ductwork, depending on the required thermal, condensation, acoustic, fire and facing performance. Confirm the duct dimensions, airflow temperature, installation environment and surface requirements before selection.

Air Handling Units and HVAC Equipment

Flexible sheets or insulation boards can be used around air handling units, fan-coil units, plenums and equipment housings where thermal control or noise reduction is required. Material form and thickness should match the equipment structure, available installation space and project specifications.

Heating and Hot-Water Pipe Insulation

For above-ambient HVAC piping, the insulation material should be selected according to the actual operating temperature, required fire performance and installation environment. FUNAS can review the project conditions and recommend available rubber foam, glass wool or rock wool options.

Acoustic and Fire Requirements

Acoustic and fire performance should be confirmed as part of the HVAC material specification. Buyers should review the relevant product test reports and local project requirements before selecting the insulation material, density, thickness and facing.

Key Factors for HVAC Insulation Selection

Operating Temperature

Confirm the operating and ambient temperature range before selecting the insulation material.

Condensation Risk

Below-ambient pipes and ducts require suitable vapor resistance and correctly installed joints.

Component Size and Shape

Pipe outside diameter, duct dimensions and equipment shape affect whether pipe, sheet, roll or board products are more suitable.

Fire and Acoustic Requirements

Confirm the required test standards, fire performance, sound control and facing options according to the project specification.
