Product Specifications

Polyisocyanurate Foam Insulation

Feature: R-value of 6 to 6.5 per inch of thickness.

Benefit: One of the highest R-values available, resulting in less thickness needed to achieve desired thermal performance. Lowers cost for owner to maintain process temperatures.

Feature: Foil facers on both sides.

Benefit: Adds additional R-Value by reflecting radiant heat. It’s a moisture barrier to help prevent costly tank corrosion.

Feature: Foil on the top edges of foam insulation.

Benefit: Additional precaution to prevent moisture penetration.

Feature: Closed-cell foam.

Benefit: Moisture Resistance. <0.3 perm water vapor transmission. <1% water absorption.

Feature: Compressive strength of 20psi to 25psi (pounds per sq. inch)

Benefit: Handles higher roof loads than fiber insulation to allow foot traffic.

Standing-Seam Construction

Feature: Machine-formed, double-locking, standing seam.

Benefit: Watertight to help prevent tank corrosion. No exposed screws to leak or loosen resulting in high maintenance cost. Superior wind load resistance. Produces an aesthetically appealing tank. Can eliminate the need for costly scaffolding, resulting in quick installation. Expansion and contraction are uniformly absorbed along the standing seams.
