SPECIFICATIONGUIDE

1.0 GENERAL KERTO HEADER 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, dimensionallystable, 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 engi-neered wood that is dimensionally stable and high-load capable. The interior is high-performance BASF Neopor® EPS Foam, whichcontains graphite particles that reflect and absorb radiant heat energy. The header can achieve R-value performances far exceedingthose possible with standard white EPS.

Kerto Header wall assemblies have a 36% improvement over conventional batt-insulated wall applications and eliminate the pos-sibility 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 otherindustrial applications.

HIGHPERFORMANCEMATERIALSMetsä Wood and BASF are industry leaders ininsulating products and structural components.Quality engineered Nordic woods from managedforests give this structural header dimensionalstability and high load capacity. The BASFNeopor® EPS foam insulation material in KertoHeader out-performs standard white EPS.Because it is a single component and as it is madewith predictable dimensions and fine tolerances,workers can install Kerto Header with greaterspeed and accuracy, saving time and materials.

R-VALUELEADERThe BASF Neopor® EPS foam used in KertoHeader achieves higher R-value performance thanstandard EPS foams because it contains graphiteparticles that reflect and absorb radiant heatenergy. Wall assemblies using Kerto Header offera 36% improvement over standard applicationsthat use sawn lumber and fiberglass batts. KertoHeader also eliminates the possibility of draft andair leakage through the header itself because of itssingle-component construction. It complies withthe 2009 International Residential Code andcarries a 20-year, 100% R-value warranty. KertoHeader is the R-value leader that puts highperformance materials to work for you.

How to use Maximum Load (PLF) Tables:1. Calculate the live load (PLF). Select a header with equal or greater capacity in the live load row.2. Calculate the total load (PLF). 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.
