Carlisle Supplies Superior Solutions to Ensure Sustainability of HVAC Systems

For almost 50 years, Carlisle HVAC Products, a vendor partner and member of the National Air Duct Cleaners Association (NADCA), has been providing innovative, high-performance products for the Heating Ventilation and Air Conditioning (HVAC) industry. Carlisle HVAC’s Hardcast and DynAir brands can provide contractors with all the materials necessary to ensure duct systems function at optimum levels. Carlisle HVAC offers rolled mastic sealants, mastics, adhesives, coatings, airfl ow management hardware, and much more.

Exterior Protection and Restoration

The Hardcast Foil-Sealant Duct Sealing System, a system that reduces ductwork air leakage, energy loss, and moisture intrusion, is a combination of rolled sealant and mastic. When properly installed, the Hardcast Foil-Sealant Duct Sealing System is eligible for a 10-year material only warranty.

This system includes Hardcast’s Iron-Grip® 601, Spray-Seal™ or Versa-Grip™ 181 liquid mastic sealant. Once the liquid sealant has cured completely, the mastic is overlaid with 4” of Hardcast’s AFT-701 rolled sealant.

This non-cracking, flexible, UV resistant Foil-Sealant Duct Sealing System will help meet the ASHRAE 90.1 2012 Duct Construction Handbook requirement of less than 2% air leakage on outside supply, return and exhaust duct work for a period of 10 years if properly installed, maintained and used for the purpose intended by Carlisle HVAC.

Ensure the longevity and efficiency of rooftop ductwork and HVAC equipment with the Hardcast Foil-Sealant Duct Sealing System.

Exterior Line Set Protection

These products are the answer to protecting line sets exposed to the elements. Although different in application, they both meet code requirements being adopted across the country.

Benefits of Carlisle exterior line set protection products include: excellent UV protection; superior protection against moisture and weather; meets code requirements.

The TPO rolled mastic sealant is a 6.5 mil TPO membrane laminated to a butyl adhesive sealant to form a 22 mil composite. The TPO Line Set Wrap is applied by peeling off the release liner while covering the pipe wrap insulation. Since this membrane is 100% solid, there is no shrinkage or additional coats required due to absorption by the insulation. This gives the product superior protection against damage from moisture, landscaping, operations, equipment maintenance, and wind.

Seal-Tack is a water-based insulation coating engineered to coat foam wrapped duct insulation and to seal cut ends of fibrous glass duct liner and it provides exceptional strength, along with weather and sunlight resistance, provides application flexibility for both indoor and outdoor use.

Restoration Sealants

RS-100 sealant is a special purpose, sprayable sealant, designed to be used internally. Of prime importance in hospital applications, RS-100 mold and bacteria growth. It can be spray applied by robots after installation of ducts at site or by spray gun at the fabrication shop, is water-based and does not carry any pesticide or harmful chemicals.

RE-500 is a high-performance, spray-applied insulation encapsulant and coating for use inside the HVAC ductwork. RE-500 coating is formulated with EPA registered chemicals to resist microbial growth on the surface of the coating. It is cost effective, available in both black and white colors, and is very low-VOC product, ideal for hospitals and schools.
