Southern Insulation, Inc. was founded in 1971 as an independent insulation contractor. Louis Strieter, the founding president brought with him over twenty five years of insulation contracting experience. This experience served as the foundation for the solid growth of this company. Our experience covers a wide range of projects including power plants, hospitals, commercial and government buildings. Today, Southern Insulation is the Baltimore - Washington area's only contractor concentrating in the hazardous abatement, mechanical insulation and fireproofing/firestopping and general contracting fields.

Southern Insulation is a service-oriented company, working to reduce your company's risk of future liability. As an environmental contractor, we clearly understand the inherent perplexities commonly associated with the environmental consciousness of today. However, by working with advanced and developing technologies, Southern Insulation is prepared to meet these challenges.

As we move forward to provide safe and lasting solutions to your firm's needs, Southern Insulation is firmly committed to superior turnkey service.
