Example design of an enclosure

ENVIRO FRAMING Stage One

Primary Exterior Wall uses 2x6 studs @ 24" on center aligned with trusses, single top and bottom plates, with sheathing (second plate or reduced stud spacing may be required structurally or by codes)

Window and Door Openings are framed per Enviro System ? details to increase cavity sizes for insulation, to use correctly sized lintels for each openings minimizing lumber usage, and to provide a consistent design height above floor

Roof System uses trusses with full 7 ?" or greater heel depth, attached with hurricane ties, sheathing and shingles per local codes

Primary Wall Insulation is R20 fiberglass batts in 2x6 wall cavity

Vapor Barrier is 6 mil CMHC approved poly or equivalent applied as a continuous interior envelope to walls and ceilings prior to non-structural framing and uses R2000 ? continuous seal techniques per 'Blower Door' air test standards

Air Barrier is applied over exterior sheathing with continuous seal top, bottom, and openings (is not recommended with stucco or in high humidity locations)

ENVIRO FRAMING Stage Two

Secondary Ceiling uses 2x4's flat @ 20" on center to bottom chords of trusses over vapor barrier to eliminate truss ties, wall backing, and 2nd interior top plate while creating a wiring and mechanical cavity inside the interior envelope

Secondary Exterior Wall uses 2x3 metal studs @ 14 ?" on center (to fit insulation batts) over all primary exterior walls to create a 9" nominal, or 8" actual wall thickness (or 7" nominal, 6" actual if used with 2x4 primary exterior walls where climatically possible)

Thermal Breaks use 1 ?" (R7.5) x 8" rigid insulation for truss heels and top plate area, 3" (R10) x 2 ?" rigid insulation and ?" plywood @ bottom and all exterior openings to provide both nail backers and thermal breaks

Interior Partitions for all non-structural walls are installed after secondary ceiling and walls using OVE (Optimum Value Engineering) framing techniques to minimize material usage
