HVAC / VRF / CHILLED WATER / FIBER-FREE DUCT INSULATION
Whether you need to insulate refrigerant, VRF (variable refrigerant flow), VRV (variable refrigerant volume), chilled water piping, HVAC equipment, chillers, tanks, vessels, or ducts (wrap or liner).
EPDM (ethylene propylene diene monomer) pipe, equipment, and duct insulation is available in preformed unslit tubes, sheets, rolls (with or without a PSA), and factory-fabricated fittings, insulated pipe hanger supports, Aerocel adhesives, zero-perm EPDM Pro – tape and Insulated Coat UV-protective coatings, all designed to conserve energy, control condensation, prevent corrosion under insulation, reduce the potential for mold growth and attenuate HVAC background noise.
More about HVAC
For demanding applications that require below-ambient (cold) line temperatures in high-temperature and high-humidity environments, It offers the lowest perm rating of domestically-available closed-cell elastomeric foam with a water vapor permeability (WVP) rating of 0.01 perm-inch. This WVP rivals that of cellular glass but with reduced thickness requirements due to an efficient thermal conductivity k-factor of .245 @ 75°F.
VRF/VRV systems continue to experience rapid growth in demand and are designed to operate at service temperature from below 32°F (0°F) to +248°F (120°C). System manufacturers require a continuous service temperature of insulation rated for at least +248°F (120°C). This insulation EPDM is the only domestically-manufactured flexible closed-cell elastomeric foam insulation with an upper continuous service temperature of 257°F (125°C) with availability in IDs as small as ¼” and thicknesses up to 2”.
While cellular glass is commonly specified for chilled water applications, lightweight, flexibility, low thermal-k, competitive water vapor permeability, and material cost (no separate fabrication step in the supply chain).
Additionally, it’s always fiber-free, microbial-resistant and GREENGUARD Gold Certified for low chemical emissions. This sheet & roll insulation is also available with a factory-applied pressure-sensitive adhesive (PSA) for tenacious bonds to clean sheet metal while saving labor when compared to wet-applied contact adhesives.
This EPDM closed-cell elastomeric foam rubber insulation is a proven choice for improved efficiency, design, and more. When properly installed, you can count on the following performance benefits:
- Upper continuous service temperature of 257°F (125°C)
- Lower continuous service temperature of -320°F (-196°C)
- Closed-cell structure with built-in vapor retarder that effectively controls condensation
- Protection against pipe corrosion for favorable life cycle costs
- Safe for stainless steel piping; does not cause external stress corrosion cracking (ESCC)
- Natural mold resistance, which means longer-lasting materials and reduced health risks to building occupants; no added biocides
- Naturally UV-resistant (condensers & rooftops) for enhanced durability and longevity
- Available in pipe sizes as small as ¼” and wall thicknesses up to 2” thick
- EPDM zero-perm tape (Protape) to seal and protect glued seams from water vapor drive
- Passes ASTM E84 25/50 flame/smoke standard up to 2” (50 mm) thick for increased fire protection
Whether you need to insulate small or large piping, fittings, valves, couplers, pumps, equipment, tanks, vessels, or ductwork, we’re here to help you select the right HVAC, refrigerant, VRF, VRV, chilled water, or duct insulation system for your application.
