ZIP System wall combines the strength and stability of a high-performing panel with the enhanced weatherability provided by the product's water-resistive barrier. With an instant 180-day rough dry-in, you can schedule your subcontractors sooner, and you’ll never have to worry about housewrap tearing off or blowing away. Because ZIP System wall panels install in fewer steps than traditional housewrap, your houses will be finished faster and sold sooner, saving interest costs on construction loans.
