KARNAK 27 Fibered Aluminum Roof Coating is made of selected asphalts and pigment flakes of pure aluminum, blended with petroleum solvents and mineral fibers. When KARNAK 27 Fibered Perfectseal Aluminum Exterior Coating is applied to the roof, the aluminum flakes leaf to the surface, forming a reflective, metallic shield over the base material.

The advantages of this metallic aluminum shield are twofold:

A. The asphaltic oils in the base coating are protected from harmful intense rays of the sun by the reflective properties of the aluminum. Over 50% of the sun’s rays are reflected by this aluminum shield, thereby preventing these oils from being “cooked” out of the base coating. The coating, therefore, retains its resilient characteristics and will not prematurely crack or dry out.

B. During the hot summer months, KARNAK 27 Fibered Perfectseal Aluminum Exterior Coating will help reduce indoor building temperatures and improve inside living and working conditions. KARNAK 27 Fibered Perfectseal Aluminum Exterior Coating prevents the sun’s rays from penetrating the roof coating and passing the heat into the building interior.

The combination of these protective materials – aluminum, asphalt and reinforcing fibers – by the exclusive KARNAK process results in a self-protecting roof coating with longer-lasting heat resistant features. KARNAK 27 Fibered Perfectseal Aluminum Exterior Coating remains tenaciously bonded to the base material, thus assuring longer roof life, with subsequent savings on roof maintenance.
