The HERCULES Series Vertical Lift cold storage door is a cold storage system that is available in multiple thicknesses, widths, and heights. It is flexible in design, and can be applied to multiple building applications. Kingspan’s cold storage doors provide superior airtightness, thermal performance of high R-value, and low thermal bridging. This can result in an energy cost savings of as much as 30% over traditional multi-part cold storage doors.
