PROBLEM TO BE SOLVED: To provide foam forming methods which allow long and stable storage in a raw material state before foaming in spite of pre-blending of a blowing agent and provide foams with good thermal insulation.SOLUTION: A foam forming method uses a two-part curable foamable composition comprising: a polyisocyanate composition (A); and a polyol composition (B) that contains one or more hydrohaloolefin blowing agents, silicone surfactants, polyols and amine catalysts and does not contain water. 【課題】あらかじめ発泡剤を配合しているにもかかわらず、発泡前の原料の状態では長期間安定して保存可能であり、得られる発泡体が良好な断熱性を示すフォーム形成方法の提供。【解決手段】ポリイソシアネート組成物（Ａ）と、少なくとも１種類のヒドロハロオレフィン発泡剤、シリコーン系界面活性剤、ポリオール及びアミン系触媒を含み、水を含まないポリオール組成物（Ｂ）からなる２液硬化型発泡性組成物を用いるフォーム形成方法。【選択図】なし
