Box 7000 | Carlisle, PA 17013 | Fax: 717-245-7053 | www.carlislesyntec.com Overview InsulBase is a rigid-roof insulation panel composed of a closed-cell polyisocyanurate foam core bonded on each side to glass-reinforced felt (GRF). Features and Beneﬁ ts »InsulBase polyiso insulation provides the highest R-value per inch of commercially available insulation products »Environmentally friendly construction with 0% ozone-depleting components and CFC free »Approved for direct application to steel decks Panel Characteristics »Available in 4' x 4' (1220 mm x 1220 mm) and 4' x 8' (1220 mm x 2440 mm) panels in thickness of ½" (13 mm) to 4.5" (115 mm) Applications »Single-Ply Roof Systems (Ballasted, Mechanically Attached, Fully Adhered) Installation Ballasted Single-Ply Systems Each InsulBase panel is loosely laid on the roof deck. Butt edges and stagger joints of adjacent panels. Install the roof membrane according to Carlisle’s speciﬁ cations. Mechanically Attached Single-Ply Systems InsulBase panels must be secured to the roof deck with fasteners and plates (appropriate to the deck type). Butt edges and stagger joints of adjacent panels. Install the roof membrane according to Carlisle’s speciﬁ cations. Fully Adhered Single-Ply Systems InsulBase panels must be secured to the roof deck with fasteners and plates (appropriate to deck type). Butt edges and stagger joints of adjacent panels. Install the roof membrane according to Carlisle’s speciﬁ cations. InsulBase 4' x 8' panels can be secured to the roof deck with Carlisle’s FAST® Adhesive, either full coverage or bead spacing. InsulBase 4' x 4' panels may be adhered to prepared concrete deck with a full mopping of Type III or IV asphalt. Review Carlisle speciﬁ cations and details for complete installation information.
