KingZip Insulated Standing Seam Roof Panel

KingZip insulated metal roof panels were designed with energy-efficiency, durability, and low maintenance in mind. As a single component roof system, KingZip greatly reduces on-site installation time compared to traditional multi-part roof systems. KingZip’s superior thermal and airtight design lowers buildings’ operational energy demands, and as a result, reduces its carbon footprint.

  • Vertical side seam and integral batten provide an attractive linear accept to any roofing application
  • Factory cutbacks at eaves and end laps available
  • Easily adaptable to accommodate safety and fall arrest systems
  • Available in thicknesses ranging from 2”- 6”, allowing for an R-value of up to 43
  • Available in Cool Roof® coatings, intended to reduce solar heat gain and improve energy efficiency
  • GREENGUARD Gold Certified
