3 KERTO USA page 3/12 SPECIFICATION GUIDE 1.0 GENERAL KERTO is a Structural Insulated Header designed to meet the current energy conservation code. It complies with the 2009 IRC. This unique header solution combines two high performance materials into a one-piece, dimensionally stable, structural header with exceptional insulation performance and high-speed installation. Kerto Header s outer structure is comprised of Metsä Wood Kerto Plank Laminated Veneer Lumber, a superior-quality engineered wood that is dimensionally stable and high-load capable. The interior is high-performance BASF Neopor EPS Foam, which contains graphite particles that reflect and absorb radiant heat energy. The header can achieve R-value performances far exceeding those possible with standard white EPS. Kerto Header wall assemblies have a 36% improvement over conventional batt-insulated wall applications and eliminate the possibility of draft and air leakage through the header itself. High load capacity and predictable performance: 2.0 MOE; 2900 FB. 2.0 INTENDED USE This product is intended to be used as headers for roof and floor loads under dry conditions of use, and other industrial applications. 3.0 DIMENSIONS, COMPOSITION AND TOLERANCES Nominal Thickness (inches) 3-1/2 5-1/2 Widths 9-1/4, 11-1/4 9-1/4, 11-1/4 Lengths 16, 24 16, 24 Weight PLF 9-1/4: 5.3 lbs., 11-1/4: 6.4 lbs. 9-1/4: 5.4 lbs., 11-1/4: 6.6 lbs.

4 KERTO USA page 4/12 HIGH PERFORMANCE MATERIALS Metsä Wood and BASF are industry leaders in insulating products and structural components. Quality engineered Nordic woods from managed forests give this structural header dimensional stability and high load capacity. The BASF Neopor EPS foam insulation material in Kerto Header out-performs standard white EPS. Because it is a single component and as it is made with predictable dimensions and fine tolerances, workers can install Kerto Header with greater speed and accuracy, saving time and materials. R-VALUE LEADER The BASF Neopor EPS foam used in Kerto Header achieves higher R-value performance than standard EPS foams because it contains graphite particles that reflect and absorb radiant heat energy. Wall assemblies using Kerto Header offer a 36% improvement over standard applications that use sawn lumber and fiberglass batts. Kerto Header also eliminates the possibility of draft and air leakage through the header itself because of its single-component construction. It complies with the 2009 International Residential Code and carries a 20-year, 100% R-value warranty. Kerto Header is the R-value leader that puts high performance materials to work for you.

Select a header with equal or greater capacity in the total load row. The header you select must satisfy both requirements for live and total load. Tables are for simple span headers only - headers with a support at each end. Allowable stresses used to calculate roof values are increased where permitted by a load duration factor of 1.15 for snow loads.
