Box Header Construction Framing Details

Building framing details permit continus insulation and energy savings (C) Daniel FriedmanSketch at page top and accompanying text are reprinted/adapted/excerpted with permission from Solar Age Magazine - editor Steven Bliss.

"The Two-Stud Corner and Other Tricks: these simple modifications in framing add insulation and and reduce costs" - links to the original article in PDF form immediately below are followed by an expanded/updated online version of this article.

This article explains how the two-stud corner framing detail permits full insulation to be installed to the building corner in a wood-framed structure. Included with the explanatory text are sketches such as shown at page top and at left.

The builder uses steel drywall clips or a 1x3 wooden backer to secure drywall in the building corner where the third stud is eliminated.

To improve the building insulation blanket at headers over windows and doors, the builder uses short cripple studs over the opening, converted into a structural beam by addition of 1/2" plywood sheathing on both sides, gluing and nailing the plywood in place to form a rigid box beam.

Don't forget to insulate between the cripple studs before nail-gluing the enclosing plywood. This box beam design can easily extend over a six-foot sliding door while meeting residential structural loads.

(See Technical note No. C 426 published by the American Plywood Association).
