When it comes to the building envelope, a system’s approach is ideal to ensure products work in concert to protect against moisture and air intrusion. This includes not just the housewrap and flashing, but also the cladding. The weatherproofing layer you choose can impact the overall look, performance, and longevity of the siding itself.
Here’s a breakdown of which housewrap systems pair best with the most common types of siding materials.
Wood easily absorbs moisture, and if it doesn’t dry on the backside, that moisture will escape through the paint or stain. This can increase the long-term maintenance costs for the homeowner while decreasing the longevity of the siding. Wood siding particularly benefits from a rainscreen, such as our Slicker Rainscreen System, to provide drainage as well as ample space for air circulation to help keep the back of the cladding dry.
Vinyl material tends to be very durable, and its plastic content helps with waterproofing. Vinyl is also typically installed on strips, allowing for some drainage to naturally occur behind the siding. The Flatwrap HP Housewrap System can provide basic protection for this type of cladding. If you’re in an area with coastal rain or using an insulation-backed vinyl siding, it’s a good idea to upgrade to our Drainable Housewrap System to allow for additional drainage capacity and remove any water build-up behind the siding.

It’s no surprise that metal exteriors attract a lot of heat. For this reason, we recommend using our Drainable Housewrap System or our Air Barrier Drainable Housewrap System. The TPO plastic spacers in these systems resist the heat transfer and create a consistent gap to prevent condensation and allow drainage of liquid water.
Brick, Stone, and Stucco
Like wood, masonry is an absorptive cladding material and therefore needs ample drying space behind it. Our Rainscreen System for Masonry is recommended for any brick, stone, or stucco application. It includes Slicker Max, which provides a ¼” gap to promote ventilation and drying on the backside of the masonry product, helping to keep walls dry. When used in conjunction with Flatwrap HP and HydroFlash self-adhered flashing, this system provides maximum protection. Additionally, using the Rainscreen System for Masonry can help meet new codes mandating a rainscreen behind stucco in certain geographic areas.

Fiber Cement and Engineered Wood
For these cladding systems, we recommend using our Drainable Housewrap System or our Air Barrier Drainable Housewrap System. Both of these allow a space for drainage and elimination of bulk water, ensuring your wall system stays free of moisture. Some fiber cement or composite siding manufacturers in these categories even require a rainscreen or 1mm non-compressible space behind the cladding.
Leaving open spaces between panels or planks of siding is a growing aesthetic trend, using natural hardwood or composite decking as cladding. Along with the material-specific moisture-elimination considerations mentioned above, you’ll also need to consider UV protection when using open-joint cladding systems, due to the increased long-term exposure between siding panels or planks. Our UV-Protected Rainscreen System covers both moisture and exposure concerns, with a UV-rated rainscreen system and UV-resistant flashing tape. Plus, the black color preserves the open-joint aesthetic.
