Recommended Tools & Fasteners:
- Tin snips
- Stinger cap stapler
- Plastic cap staples
- Galvanized nails
- Utility knife
- Keel crayon
- Tape measure
- Kilz primer
Do not install any other type of insulation below DripWave.
All components of the DripWave system (below) are needed for installation.
DripWave may be installed over sheathing or open framing.

DripWave is a wall insulation system for external stucco walls comprised of:
DripWave Weep Screed
Mesh or vinyl tape per local building codes
Water-resistive barrier (WRB)
- Inspect all substrates to ensure that they are clean, dry and structurally sound.
- Ensure that planar irregularities do not exceed more than ¼ inch over 10 feet.
- Inspect all wood-based sheathing to ensure that it is gapped 1/8” to allow for expansion and is attached with corrosion-resistant fasteners per code requirements.
- IMPORTANT: Any cut edge of OSB sheathing should be primed with a product such as Kilz to prevent expansion.
- Inspect all nailing and fasteners. All nails and fasteners must be flush before installation of the WRB.
- Cover all sharp edges of exterior metal with butyl waterproofing membrane to ensure the WRB is not torn during installation.
- IMPORTANT: Do not use a bituminous type sealant or oil-based waterproofing material. This type waterproofing may not be compatible with DripWave or other waterproofing materials and cause failures.
- Inspect all DripWave panels to make certain they are not cracked or damaged, and that the tongue and groove on each panel are intact.
The installation steps below show the typical basic installation process. Always follow local regulations as well as manufacturer’s instructions for installation, storage and care for all products, including DripWave, Weep Screed, WRB, lath and stucco.
NOTE: DripWave paneling is installed in exactly the same way as standard EPS insulation. However, there are 4 important instructions to follow:
Watch the Installation Video
1.Using galvanized nails, install DripWave weep screed against the sheathing. Using tin snips, cut the metal to the proper length as appropriate. Ensure there are no sharp edges protruding that might rip the WRB.
IMPORTANT: Ensure weep screed is level with the sheathing.
NOTE: If installing over open framing, attach to frame with galvanized nails per local codes.
2.Using a Stinger cap stapler with plastic cap staples, install the WRB according to local regulations and manufacturer specifications. Ensure that the WRB wraps around each corner and overlaps per code requirements. WRB must extend over the face of the weep screed.
3.Clearly mark the center of each stud on the WRB.
4.Beginning at the bottom corner of the exterior wall, install the first DripWave panel, placing it inside the weep screed track.
5.Ensure that the arrow printed on the DripWave panel is pointing up, and that DripWave printing is right side up and visible after installation. Properly installed DripWave paneling has the flat part of the panel facing towards you, with the tongue up. If you see the wave pattern after installation, it is not installed correctly.
6.Ensure that the panel ends with a seam in the center of a stud.
7. Adjust the panel length as necessary using a utility knife to cut the foam.
IMPORTANT: Do not cut foam against WRB because the knife may damage the WRB. When DripWave panels must be cut, remove the panel from the wall before cutting.
NOTE: Dimples are placed every 2 inches on the flat side of the DripWave panel to aid in measuring and cutting.
8. Tack the DripWave panel into place using galvanized nails to secure it as needed.
9. Continue placing DripWave panels along the bottom of the wall, using galvanized nails to secure the panels as required. Butt the vertical joints together and ensure there is a tight seal between the panels with no gaps. Cut the panels as necessary using a utility knife. Ensure that all panels are tight and flush.
10.Mark the center of each stud on the installed DripWave panels with a Keel crayon.
11. Begin installing the next row of DripWave paneling, nesting the tongue and groove together tightly across the entire span of the board. Stagger all butt joints and ensure both ends of the new panel are centered on studs.
12. Tape all vertical joints with mesh or vinyl tape per local building codes.
13. Attach the lath to the outside of the DripWave panel per the lath manufacturer’s recommendations.
NOTE: Local regulations dictate what type of lath may be used.
14. Attach the edge guard to the corner of wall over the lath and inside the weep screed.
NOTE: It's important to ensure that no WRB is exposed.
15. Apply exterior grade sealant around all wall penetrations (doors, windows, vents, pipes, electrical, etc.) to seal foam to the penetrating article. If needed, cut a 45 degree angle bevel into foam around penetration to allow for sufficient sealant to be applied.
