ABSTRACT:
Walled structures are prepared from foam-in-place components such as those used to prepare rigid polyurethane foams wherein successive strips of foam are deposited and hardened within a three-sided enclosure having a generally H-shaped configuration. A foraminous scrim such as glass fiber mesh forms part of the vertical legs of the H and foam is disposed below the cross piece of the H to bond to adjacent scrim facing sheets and scrim of a previously disclosed strip. The foam is significantly reinforced, joined to the previously deposited structure and foaming components are isolated from depositing apparatus.
