Details

Keystone Weep Vents are specifically designed for use in masonry perp joints above lintels, providing reliable drainage and ventilation where water can accumulate. These vents are essential for builders, contractors, and site managers focused on meeting regulatory standards and maintaining cavity wall integrity. Please note, these vents are installed individually within the perp joints for optimal performance.

Application

These weep vents are installed over lintels to allow trapped water to escape from DPCs, cavity trays, and lintels themselves, preventing moisture-related damage. Additionally, they facilitate airflow within the cavity, supporting the wall’s breathability and reducing the risk of damp or mould. Keystone Weep Vents are commonly specified to comply with UK NHBC and Building Regulation requirements, ensuring your build meets current standards.
