Spray Foam Insulation:  1-Component Foam 

One-component spray foam is designed for small gaps and crevices, and dispensed to areas typically visible to the building’s inhabitants.


In most cases, one-component foam is used for pipe penetrations and cracks in high-exterior walls for locations such as gymnasiums, boiler rooms, and cafeterias. 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 thatallow our technicians to access difficult locations while maintaining the integrity of the building’s contents and occupants.

One-component spray foam is dispensed as a caulking bead with an approximate 200% expansion rate. This industrial foam sealant is a moisture cured product using humidity to dry and UL Classified File #R13919 Caulking & Sealant.


In areas with wider gaps in the building’s envelope such as roof level changes and roof/wall joints, two-component foam may be used in conjunction with one-component to ensure a seal to the exterior environment.
