When summer brings extreme heat and humidity, your choice of house wrap matters more than ever. High temperatures combined with moisture can stress your building envelope — leading to trapped vapor, condensation, and long-term damage if your wrap isn’t up to the task.
Here’s how summer conditions affect house wrap — and how ALTA® 360’s drainable technology helps protect your builds.
☀️ The Summer Challenge: Heat, Humidity & Moisture
- High Humidity: Moisture in the air can accumulate behind siding without proper drainage.
- Intense Heat: House wraps without UV stability or thermal resilience may degrade faster when exposed during construction delays.
- Sudden Storms: Summer often means pop-up storms — water intrusion risks rise, especially before siding is installed.
- Trapped Moisture: Standard house wraps that don’t drain can lead to mold, rot, and reduced energy efficiency.
🔧 Why ALTA® 360 Performs in Summer Conditions
✔ 360° Drainability: ALTA® 360 channels water away in any installation direction — vertical or horizontal. No special techniques required.
✔ Balanced Permeability: Blocks water while allowing moisture vapor to escape — critical in humid climates.
✔ Durable in Heat & UV: Built to withstand construction delays and prolonged exposure to sunlight.
✔ Tear-Resistant: Resists rips and blow-offs during summer windstorms.
✔ Tested for Real-World Performance: Meets and exceeds ASTM standards for water resistance, UV exposure, and drainage efficiency.
🔗 Pair It with the Right Accessories
Don’t forget — performance is only as good as your weakest link. ALTA® accessories like flashing tape, seam tape, and sealant are designed to complete the building envelope and maintain water resistance in tough summer conditions.
