Eco Tec Insulation, Skokie

For more than 25 years, Eco Tec Insulation has joined forces with homeowners, architects, designers, and commercial builders to handle insulation issues, big or small. The company utilizes advanced spray-foam technology, effectively putting a stop to air activity between wall, floor, and ceiling cavities. The spray-in-place foam insulation seals even the tiniest of seeps—such as those around electrical outlets and light fixtures—meaning outside air cannot get in and ghost pets cannot sneak out when nobody’s looking.
