    Description

    A new system of wood-frame house construction has been developed which combines increased use of low-grade wood, prefinished components, and rapid field assembly methods without much divergence from conventional construction. Laboratory evaluations of the components of the Nu-frame system indicated that; (a) 4-foot spacing of the W-trusses tested provides a safety factor of three over design load, (b) the wall framing system with 4-footspacing of double 2- by 4-inch studs (Nu-frame) is a reasonable method of construction, (c) the use of a l/2-inch fiber board filler between studs (Insul-2) provides racking resistance as well as adequate thermal and sound insulation, (d) the interior finish (Perm-board) has greater stiffness and strength over a 48-inch span than 3/8-inch gypsum board over a 16-inch span, and (e) the prefinished roof covering (Plastic plank) provides excellent resistance to moisture entry. The use of both mechanical fasteners and adhesives assures rapid on-the-job assembly of framing and covering materials and low site labor costs. This laboratory evaluation will be followed by construction of an experimental unit for further study.
