Achieving both rain protection and ventilation is possible! It enables seal-less construction with the included EPDM foam.
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 boards and a unique shape that incorporates 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 for easier installation at corners ■ Unique shape with a slope inside the ventilation material in addition to two water return boards ■ Excellent rainwater management proven through air and water distribution tests ■ Sufficient ventilation area secured with an effective ventilation hole area of 68.0 cm²/m
