I’ve always enjoyed reading — and writing — about company histories. Whether it’s a small one-person operation that has stayed that way for 55 years or grown into a multistate ductwork fabrication powerhouse, I find it fascinating.

While other products that boost the energy efficiency of homes and buildings are often mentioned by home improvement experts as a great way to save on utility bills through upgrading, sealing ductwork is often left out. 

As part of the celebration of its 50th anniversary, Carlisle HVAC Products has redesigned www.CarlisleHVAC.com.

Carlisle HVAC Products’ new Edge Sealer is an aerosol spray made for indoor use to capture cut ends of insulation and ductwork materials on the jobsite, making sure the HVAC system performs as designed.
