Designed for long-term protection and code compliance, these solutions deliver reliable defense against water, wind, and weather exposure.
Drainable Housewraps
TYPAR
Thanks to an integrated layer of randomly oriented fibers, the company’s Drainable Wrap has an effective drainage gap that gives it the ability to shed excess moisture faster than conventional housewraps. With this wrap, builders get the industry-leading performance of building wraps with an integrated solution to manage bulk water that gets behind cladding. No other product brings together that capability with the exceptional tear strength, holdout, and breathability building wrap is known for. It is ready to go to work right alongside the manufacturer’s full line-up of high-performance flashings, tapes, and accessories to protect against the elements. For more information, visit typar.com.

Self-Adhered and Fluid-Applied Air and Water-Resistive Barriers
Sto Corp.
The company announces the launch of StoShield SA and Sto GoldSeal STPE, next-generation air and water-resistive barrier solutions that are part of the complete Sto system of envelope technology. StoShield SA is a high-performance, self-adhered AWRB available in two configurations:
- StoShield SA VP – a vapor-permeable barrier that prevents air leakage and water intrusion while allowing moisture and vapor to escape, reducing the risk of trapped condensation.
- StoShield SA NP – a non-permeable version that provides maximum protection by preventing both air and vapor movement, making it ideal for high-moisture or cold-climate applications.
With factory-controlled thickness, an aggressive primer-less adhesive, and instant waterproofing, it ensures consistent coverage, improved installation efficiency, and reliable long-term protection. The UV-cured acrylic adhesive bonds in cold temperatures and offers visual alignment through a printed grid pattern, streamlining on-site application.

Drainage Mat Products
Stockton Products
Tru-Weep is a complete line of stucco accessories designed to accommodate drainage mats within stucco assemblies. This product line maximizes drainage and ventilation by aligning the open-air slots with the drainage mat. This Tru-Weep product line also prevents the weep holes from clogging with stucco because the slots are located directly under the drainage mat. All nine Tru-Weep profiles are fully customizable to ensure the proper ground size and flashing leg requirements are accommodated. Tru-Weep is manufactured in G-90, aluminum, stainless steel, or bonderized (paint-ready). For more information, visit stocktonproducts.com.

Black Mat Fleece Facer
ROCKWOOL
Cavityrock Black is also available with the addition of a black mat fleece facer. It is designed to mask the insulation layer to create a crisp, black aesthetic in open-jointed cladding systems. Because it combines the insulation and facer in a single step, it can reduce installation time and material cost to achieve your desired design aesthetic. The fleece material has been designed for exposure to the elements (weather, heat, UV), while maintaining the thermal and acoustic performance and fire protection expected of stone wool. The fleece facer is chemically bonded to the insulation during the manufacturing process, offering improved mechanical properties and superior long-term performance.

Moisture-management Casing Bead
Trim-Tex Exterior Solutions
The company offers many products that deliver strong moisture management. The Ultra-Casing Bead features a built-in moisture flange that eliminates the need for a backer rod and improves sealing around window and door openings in stucco and stone veneer applications. It’s easy to handle, UV rated and is available in several colors. For more information, visit exterior.trim-tex.com.
Moisture Vapor Permeable Wrap
OX Engineered Products
The company’s HomeGuard housewrap excels in air and water resistance, moisture vapor permeability and durability. The product is an engineered, woven, polyolefin material designed for use as a secondary weather resistive barrier. The strong woven fabric ensures jobsite durability, even in the harshest conditions. Its micro-perforations allow damaging moisture as a vapor to escape while shedding bulk water. It come with six-month UV resistance.
- Surpassed the ICC-ES AC38 test requirement of ten minutes when tested according to ASTM D 779.

Rainscreen System
Grad Concept USA
Grad for Kebony is a rainscreen system developed for the North American building envelope industry and interior accent walls. The product utilizes a special cladding profile, expressly designed for the Grad Mini Rail system, which precisely locks Kebony Grad cladding into place quickly and easily. The company provides an off-the-shelf, passive rainscreen with completely hidden fasteners, no pre-drilling, and perfectly aligned boards in the most popular gap options, all while cutting install time in half. The clips are factory-placed in position, so the installer simply fastens the rails onto the sheathing or vapor barrier and snaps the boards on. For more information, visit us.gradconcept.com.

Polymer Rainscreen System
ClarkDietrich
By using ClarkDietrich E-Screen, the water inside the wall is drained away more efficiently and the increased ventilation properties allows the system to dry out more effectively. Its 95 percent open design creates a continuous capillary break and a channel for moisture to drain away from the wall system while accelerating the drying time. The durable polymer material is corrosion-resistant, rust-proof and mildew/mold-resistant. The 2-Ply design is comprised of a backer fabric that deflects the stucco away from the open design and improves the tensile and compressive strength properties of the rainscreen.
