The commonly used insulation materials for air conditioning and solar energy systems mainly include the following types, which will be explained based on their characteristics and application scenarios:

1. Rubber insulation material

Features: Made mainly of rubber and polyvinyl chloride, with a closed cell foam structure, low thermal conductivity (about 0.035 W/mK), waterproof and moisture-proof, flame retardant (B1 level), and easy installation.

Application: Widely used for antifreeze in air conditioning ducts and solar water pipes, commonly in the form of self-adhesive insulation pipe sleeves or boards, with a thickness typically ranging from 10-50mm.

2. Glass wool

Features: Fiber like material, covered with aluminum foil veneer, good thermal insulation performance (thermal conductivity ≤ 0.035 W/mK), and also has sound absorption effect, but attention should be paid to moisture resistance.

Application: Mostly used for external insulation of central air conditioning ducts, with a thickness generally ≥ 25mm.

3. Rock wool

Characteristics: Made from basalt as raw material, it is resistant to high temperatures, non hygroscopic, and has excellent fire resistance. However, fiber irritation protection is required during construction.

Application: Suitable for sound insulation inside large air conditioning ducts or insulation in high-temperature environments.

4. Polyurethane foam

Features: Low thermal conductivity, lightweight and waterproof, but requires the addition of flame retardants, with high construction requirements.

Application: Cold storage or building exterior wall insulation, rarely directly used for pipelines.

5. Aluminum foil composite insulation material

Features: The aluminum foil layer enhances the reflective and thermal insulation performance, and is resistant to high temperatures (such as above 120 ℃). It is commonly used for sealing solar energy pipelines.

Application: Insulation for solar water heater pipes or air conditioning exhaust pipes.

 6. Phenolic insulation board

Features: Fireproof and pressure resistant, aluminum foil air duct board form, suitable for central air conditioning ventilation ducts.

Purchase suggestion:

Air conditioning ducts: Priority should be given to rubber or glass wool, taking into account both insulation and moisture resistance.

Solar energy pipeline: It is recommended to use aluminum foil rubber pipe or self-adhesive insulation cotton for anti freezing and sun protection.

The above materials can be further screened according to specific requirements such as flame retardant grade, thickness, and ambient temperature.
