General Instructions

• Frame with the 2×6 Eco Smart Stud (ES Stud) just like your standard exterior wall
• Spacers face the exterior wall
• 16” or 24“on center. Observe other framing requirements when using at 24” on center
• Standard solid top plates and bottom plate
• The ES stud can be used as cripple studs. If the slot in in the ESS is split where it touches the upper and lower framing a nail needs to be placed on each side of the slot.
• The ES stud can be used for header support
• Nailing pattern is standard, 6” on center on the perimeter and 12” on center in the field for non-high wind areas. In high wind areas follow the local code nailing pattern.  It is preferred that the nail goes through the spacer that touches the exterior sheathing but it is not necessary you do get the needed 1” of penetration needed for code if the nail misses and goes through the gap area.  When the spray foam is installed, it will glue the entire section together and reinforce the entire section.
• Gas lines, electrical, low voltage can pass through the slot. No drilling needed
• If for any reason the ES stud will not work simply use a solid 2×6 in its place
• Plywood gussets can be used to reinforce the ES stud if needed.

Windows

Good Solution: Use a solid 2×6 for the trimmers to support the header and top and bottom plate for ease of installation. Use the ES stud for King stud on both sides and for cripple studs under the window.

Better Solution: Turn the standard ES stud backwards so that the spacers face the interior wall. The sold part of the stud now faces the nailing flange of the window. This is for the top and bottom plate along with the two trimmer studs supporting the header.  King studs are faced the correct way along with cripples under the window plate.

Best Solution: Use the ES Auxiliary stud for the window plates and trimmer studs supporting the header. Use standard ES studs for the cripples under the window and for the king studs

Doors

Good Solution: Use solid stud for trimmer studs to support header. Use standard ES stud for the king studs on both sides of the header.

Better Solution: If the door has a nailing flange turn the ES stud around so the solid part of the stud faces the nailing flange. If no flange is present use as normal

Best Solution: Use ES Auxiliary stud for cripples supporting the header. Use standard ES stud for the king studs on both sides of the door.

Plumbing

While plumbing should not be in exterior walls if it is needed to cut a larger hole in an ES stud plywood gusset can be added to each side of the ES stud to reinforce it. Also, a solid stud could be used in the needed location.

Posts

ES studs can be used for posts, they are treated just like a solid 2×4 stud. In certain situations, they may need to be glued together along with being nailed.

Multiple ES studs, 3 or more together

When 3 or more studs are together, they need to have the slots lined up so spray foam can be inserted during insulation. If one or more of the studs are not full length the studs should all be matched up before put into the wall so that all slots and notches will align for insulation. This most common around windows.

There is no top or bottom to the ES stud.  Cut needed shorter studs from either end first leaving the middle part of the stud to be used for cripple studs for above or below the window that are spaced apart.
