Architects, home designers, builders and contractors are starting to focus on energy efficiency, ventilation and indoor air quality to build homes that are more ecofriendly and healthier for the people who live in them. Insulation is the key, and spray foam insulation is turning out to be a favorite method. Spray foam equipment can be customized for each contractor, with spray foam rigs, foundation supports and concrete lifting rigs.
