PROBLEM TO BE SOLVED: To provide a member for forming a ventilation layer, which has a relatively simple structure and is supplied at low cost, which is excellent in adhesion with a foam-in-place urethane heat insulation material and is easily constructed, and which can contribute to improvement of separability in the case of building demolition.SOLUTION: A member S for forming a ventilation layer is used for holding a ventilation space 15 when holding the ventilation space 15 between a plate material 12 and a wooden frame 11 and constructing a foam-in-place urethane heat insulation material 13. The member S is made by forming protrusions 2 having through-holes 3 in their top parts at a height corresponding to a short-sized dimension of the ventilation space 15 in a sheet-like or film-like material-made substrate 1. A foam undiluted solution comes off the through-holes 3, and thin adhesive joints 13a are formed like dots on a surface side of the member S for forming the ventilation layer. |
