Achieving both rain protection and ventilation is possible! With the included EPDM foam, we realize sealant-free installation.
The "Kasa-gi Ventilation Material" is an exterior construction component that achieves a sealing-free installation by bonding EPDM foam as the exterior material. To ensure safer use on-site, the size has been increased to 20×t10mm, allowing it to be installed on metal siding with significant irregularities. Additionally, with two water return plates and a unique shape that includes a slope inside the ventilation material, rainwater is effectively drained outside even if it enters. 【Features】 ■ Increased size of EPDM foam ■ Comprehensive improvement of components, making corner installation easier ■ Unique shape with a slope inside the ventilation material in addition to two water return plates ■ Proven excellent rainwater management in air blowing and sprinkling tests ■ Sufficient ventilation area secured with an effective ventilation hole area of 68.0 cm²/m
