Tyvek, a synthetic material, is commonly used as house wrap, a protective barrier installed on the exterior of a home before siding is applied. It helps to protect the home from moisture, air infiltration, and other elements. Installing Tyvek house wrap is a relatively simple process that can be completed in a few hours. However, there are a few things to keep in mind to ensure a successful installation.
Before you begin, make sure you have all the necessary materials. You will need Tyvek house wrap, a utility knife, a hammer or staple gun, and nails or staples. You may also want to wear gloves and safety glasses for protection. Once you have gathered your materials, you can begin the installation process. Start by unrolling the Tyvek house wrap and cutting it to the desired length. The wrap should be long enough to cover the entire exterior of the home, from the foundation to the roofline. Once you have cut the wrap to the desired length, you can begin to install it.
To install the Tyvek house wrap, simply unroll it and staple or nail it to the exterior of the home. Start at the bottom of the home and work your way up. Overlap the seams of the wrap by at least 6 inches to ensure a watertight seal. As you work your way up the home, be sure to tuck the wrap around any windows or doors. Once you have reached the top of the home, you can trim any excess wrap. With just a few simple steps, you can install Tyvek house wrap and protect your home from the elements.
Cutting Tyvek to Size
Once you have your measurements, it’s time to cut the Tyvek to size. To do this, you will need a sharp knife or utility knife. You can also use a pair of scissors, but a knife will give you a cleaner cut. When cutting Tyvek, be sure to use a sharp blade and make clean, straight cuts. Avoid tearing the Tyvek, as this can weaken the material.
When cutting Tyvek, it is important to consider the direction of the grain. The grain of Tyvek runs in one direction, and cutting against the grain can make the material more difficult to cut and can weaken the material. To cut Tyvek with the grain, hold the knife or scissors parallel to the grain and make clean, straight cuts.
It is also important to consider the overlap when cutting Tyvek. When installing Tyvek, it is important to overlap the edges of the material by at least 6 inches. This will help to prevent water from leaking through the seams. When cutting Tyvek, be sure to allow for this overlap when making your cuts.
| Tyvek Type | Overlap |
|---|---|
| Standard Tyvek | 6 inches |
| Tyvek HomeWrap | 4 inches |
| Tyvek ProWrap | 6 inches |
Properly Lapping and Seaming Tyvek
Lapping and seaming Tyvek are crucial steps in ensuring a weather-resistant and air-tight building envelope. Here’s a detailed guide to achieve optimal results:
Lapping Tyvek
Tyvek should be overlapped in a specific direction to prevent water penetration. Start by unrolling the Tyvek and positioning it at the bottom of the wall, allowing it to extend onto the foundation by a few inches. The top edge of the lower course should overlap the bottom edge of the upper course by at least 6 inches. Use construction tape or house wrap sealant to secure the overlap along its entire length.
Taping Seams
Seams between Tyvek panels must be properly taped to prevent air and water leakage. Use Tyvek tape or a compatible high-quality house wrap tape. Cut the tape to the appropriate length and center it over the seam. Smooth the tape down firmly to create a secure bond.
Taping Windows and Doors
Tyvek must be properly flashed around windows and doors to prevent leaks. Cut Tyvek pieces to fit the sides, top, and bottom of the opening. Fold the edges of the Tyvek inward and tapeten seam with tape. Secure the Tyvek to the window or door frame with nails or staples.
Installing Corner Reinforcement
Corners are particularly vulnerable to leaks. Install Tyvek Corner Reinforcement Tape at all inside and outside corners. Unroll the tape and press it down firmly along the corner. Use nails or staples to secure it every 6 inches.
Tying Off Tyvek
Once the Tyvek has been installed, it must be tied off securely to prevent wind damage. Use a Tyvek TyWrap or similar device to wrap around the Tyvek and tie it down every few feet. Alternatively, you can use nails or staples to secure the Tyvek to the framing.
Sealing the Edges of Tyvek
Once the Tyvek is installed, it’s essential to seal the edges to prevent water infiltration and maintain the integrity of the envelope. There are several methods for sealing Tyvek edges:
Overlapping and Taping
This method involves overlapping adjacent Tyvek sheets by at least 6 inches and sealing the overlap with Tyvek tape. The tape should be applied with even pressure, ensuring a secure bond. Overlapping and taping provides a strong and reliable seal.
Liquid Adhesive
Liquid adhesive, specifically formulated for Tyvek, can be used to seal edges. It should be applied evenly to the edges of the Tyvek sheets and pressed together firmly. This method offers a durable and permanent bond.
Tyvek Flashing Tape
Tyvek flashing tape is a self-adhesive tape specifically designed for sealing Tyvek edges. It is easy to apply and provides a watertight seal. Apply the tape to the edges of the Tyvek sheets, ensuring they are clean and dry before application.
Additional Sealing Considerations
In addition to the above methods, consider the following tips for sealing Tyvek edges effectively:
- Use 2-inch wide Tyvek tape for overlaps and flashing.
- Seal all edges and seams, including corners and penetrations.
- Use a clean, dry cloth to remove any dirt or debris before sealing.

Installing Trim and Flashing
Step 1: Measure and Cut Trim
Using a measuring tape and utility knife, measure and cut the trim pieces to the desired lengths. Ensure they fit snugly around windows, doors, and other openings.
Step 2: Apply Adhesive Sealant
Apply a thin layer of adhesive sealant to the back of the trim pieces using a caulk gun. This will help secure the trim to the Tyvek and create a weather-tight seal.
Step 3: Install Trim
Press the trim pieces into place over the edges of the Tyvek. Nail or screw them securely to the supporting structures, such as siding or framing.
Step 4: Install Flashing
Cut flashing material to the desired sizes and shapes to cover the joints and corners of the Tyvek. Use a combination of L-flashing, Z-flashing, and drip flashing as needed.
Step 5: Secure Flashing
Apply adhesive sealant to the back of the flashing pieces and press them into place over the joints. Fold the edges of the flashing over the trim to create a water-resistant barrier.
Step 6: Install Counterflashing
For windows and doors, install counterflashing over the top of the flashing you just installed. This will create a double layer of protection and help prevent water from penetrating the openings.
Step 7: Seal Edges and Joints
Apply a bead of caulk to seal all the edges and joints between the trim, flashing, and Tyvek. Use a flexible caulk that can withstand the elements and prevent water infiltration.
| Flashing Type | Purpose |
|---|---|
| L-Flashing | Covers vertical joints and corners |
| Z-Flashing | Covers horizontal joints and valleys |
| Drip Flashing | Prevents water from dripping behind siding |
