Spray Foam Insulation: 2-Component Foam


Low-pressure spray foam insulation is used to increase the building's energy performance by sealing larger gaps in the construction of the structure.

Application of the product will assist energy performance by reducing airflow from the exterior environment, controlling condensation, sound dampening, and obstructing pests  from entering the building.

The insulation is applied from the inside of the building using portable foam-spraying systems that allow our technicians to access difficult locations while maintaining the integrity of the building’s contents and occupants.


Two-component insulation is made up of polyurethane spray foam that expands larger than our one-component foam in order to provide better coverage of the closed cell barrier.

While one-component foam is used for smaller and/or more visible gaps to the building’s occupants, two-component foam is typically used for larger gaps to the building envelope such as roof/wall joint connections, roof-level changes, unsealed pipe penetrations, and unused vents and holes in the building’s construction.
