When it comes to protecting walls from moisture, not all house wraps are engineered the same. Builders today need materials that can manage water effectively, breathe naturally, and stand up to tough jobsite conditions. ALTA® 360° Drainable House Wrap delivers all three — thanks to a simple but powerful two-layer design that redefines how drainage is achieved.
A Smarter Two-Layer Design
Unlike traditional house wraps that rely on textured coatings or spaced ridges, ALTA® 360° is built with just two layers working in harmony:
- Outer Film Layer: A strong, water-resistant film that blocks bulk water intrusion while allowing vapor to escape.
- CLAF® Reinforcement Layer: A patented, open-mesh scrim made from high-density polyethylene (HDPE) that provides both structural strength and built-in drainage channels.
Together, these layers create a high-performance water-resistive barrier (WRB) that installs easily, drains quickly, and maintains long-term integrity on the wall.
How CLAF® Mesh Powers Drainage
The secret to ALTA® 360° lies in its CLAF® mesh technology — a precisely oriented lattice structure that forms vertical and diagonal channels between the film and siding. These channels allow trapped water to drain out freely, meeting and exceeding ASTM E2273 drainage efficiency standards without the need for embossed textures or spacer materials.
Because the drainage is part of the mesh itself, performance never wears away, and there’s no risk of delamination between layers over time. It’s a simpler, stronger, and more reliable way to keep walls dry.
Strength and Durability Built In
The CLAF® layer doesn’t just create drainage — it reinforces the film, making ALTA® 360° significantly more tear- and puncture-resistant than standard wraps.
Installers appreciate this during windy conditions, staple-gun fastening, or siding application, since the scrim distributes tension evenly and prevents blowouts. The result is a wrap that holds up through every phase of construction and continues to perform long after the cladding goes up.
Balanced Breathability
Moisture protection isn’t just about shedding water; it’s about letting walls breathe. ALTA® 360° achieves this balance with a high perm rating, allowing water vapor to escape from inside the wall cavity while blocking exterior water penetration. This balance helps prevent mold, rot, and trapped condensation — key factors in long-term building health and energy efficiency.
Engineered Simplicity from ANCI Composites™
Every roll of ALTA® 360° is made in the USA by ANCI combining advanced polymer science with practical field experience. By using only two precision-bonded layers, ALTA® eliminates unnecessary bulk and complexity, delivering a lighter, easier-to-handle wrap that still outperforms thicker multi-layer alternatives.
Whether you’re wrapping a custom home or a large-scale build, ALTA® 360° offers 360 degrees of protection, performance, and peace of mind — all built on the proven strength of CLAF® technology.
