Single component compositions for making a moisture-cured polyurethane foam are disclosed. Foam produced from the compositions of the present invention produce very low foaming pressure due to their 60-95 percent open-cell content. After these compositions are applied and cure, they form a permanent seal around the perimeter of installed fenestration products.
