"Ventilation-kun" is a spacer for ensuring a ventilated layer in roof insulation. It prevents the collapse of the ventilation layer caused by the expansion of fiber-based insulation materials during installation. Made of cardboard material, it also functions as a moisture-permeable and windproof layer. By simply inserting it between the rafters, you can easily and reliably secure the ventilation layer. Please feel free to contact us when you need it. 【Features】 ■ Significantly reduces the time required for ventilation layer construction ■ The spring-like nature of the folded edges eliminates the need for fixing with staples, making the work easy ■ The cardboard material is moisture-permeable, allowing for the discharge of moisture ■ Also has the function of a windproof layer ■ Moisture permeability resistance: 0.6×10−3(m2·s·Pa/ng), 1.22(m2·h·mmHg/g) * For more details, please refer to the related links or feel free to contact us.
