For years, precast double walls have been in use around the world. For more than 20 years, they have been a popular choice for residential and commercial structures in Europe. In North America, their use has been limited, but is growing in popularity, due in large part for the need to create economical yet highly efficient commercial and residential structures. Much like a traditional precast sandwich wall panel, double walls incorporate a highly efficient layer of rigid insulation into the wall assembly, providing concrete with thermal efficiency and moisture prevention. However, the main reasons for choosing to use a double-wall in lieu of a sandwich wall are weight and structural connection improvements.
