Foam Over Studs – Installing STYROFOAM™ Residential Sheathing

How to Install Rigid Foam

Installation Steps

1. Mark the Dow insulation boards by dragging the hook of a measuring tape along the surface of the board while holding the other end of the tape at the desired measurement.

2. Dragging the hook will create a small mark to follow when cutting. Set the board on a flat, sturdy surface for ease and safety in cutting. A pair of sawhorses is usually sufficient for waist-high work. Follow the mark left by the tape edge, holding the knife low against the board. Don't cut all the way through; just make a deep impression with the knife blade. Once the entire measured line has been scored, simply snap off the piece, over the edge of your work surface.

3. Install a code-acceptable corner bracing such as diagonal metal strapping, let-in wood or wood structural sheathing (wood sheathing should be covered by Dow insulation boards to provide full wall insulation). Note: Dow insulation boards are not structural panels.

4. Install Dow insulation boards vertically with long joints in contact with one another and bearing directly on the framing members. Avoid horizontal joints, unless joints bear on a horizontal framing member. Taping of the insulation board joints can improve air infiltration.

5. Secure Dow insulation boards using 3/8" head galvanized roofing nails long enough to penetrate framing a minimum of 3/4"; or secure with 1" crown, 16-gauge wire staples long enough to penetrate framing a minimum of 1/2" or preferably 1" head plastic cap nails long enough to penetrate framing at least 3/4". Nail heads or staples should not be over-driven.

Secure the field of the board 16" o.c. and around the perimeter 12" o.c. or as required by the code authority having jurisdiction.

Use a utility knife and straight edge to trim the insulation board to conform to irregular wall angles, projections or wall surfaces less than board width or height.

In stick-built construction, consider using 4' x 9' Dow insulation boards to effectively cover the sill plates, floor/ceiling junctures, band box and headers in one easy application.

Brick, wood, hardboard, aluminum or vinyl sidings are fastened to the wood frame construction through the insulation in accordance with the siding manufacturer's instructions.

House wrap first or window flashing?

Perhaps a newbie question...
After framing and sheathing a wood-framed house, is the house wrap (aka Tyvek, etc) installed first to the edge of wall openings, then window/door flashing lapped over that?
Or is window flashing (10" strips of that black stuff) installed first directly on wood studs/sheathing, then house wrap lapped over that?
Siding will be stucco.
What's your vote?

  • Avatar Eddie Pat Where can I learn how to install HardiPlank siding?
    May 06, 2006 by Eddie Pat | Posted in Do It Yourself (DIY)

    I have 30 yr. old shiplap on my detached garage and would like to try to replace it with hardiplank....but I don't have much carpentry experience.

    • As a professional it is not difficult however, it is very dusty and definitely not a one person job. Start with installing your 5/4 boards on the corners of the house. Then make sure your bottom board (the first one you …edge of the first board. I would make it 7" long and that will let you maintain the same space between each row. Set the next course on the top (the bottom of the "T") and nail. Keep going until your done.

    The beam supports one side of a patio roof (17x17) that is made of shiplap sheathing covered with fiberglass shingles.

    • You need to go to a steel beam supplier and take the following information with you. They can determine the size you'd need. First take a picture of it underside and outside of the porch. They will need to know how long …br />
      The 1st responder suggested talking to an architectural engineer. No such thing. There are architecs that design and engineers that calculate loads.

      Hope this helps and isn't too confusing.

  • Avatar Deadsion Another Wooden Fence?
    Jun 25, 2007 by Deadsion | Posted in Do It Yourself (DIY)

    Anyone know how to or know of a website that explains how to make a board-on-board fence. I want to avoid having those 1-2 inch spaces between the fences after the boards shrink in a normal fence

    • Use 'shiplap' boards (they have a half inch rabbit on both sides).

      When you place them, they will overlap a half inch on both sides and the overlap will accommodate shrinkage.

      paint or stain …ge does not show a raw wood seam.

      Do not fasten at each edge, as shrinkage will then tend to split a board.

      If you use 6 inch boards, use 2 fasteners about an inch and a half from each edge.
