On the Mark Spray foam is a family owned company that has been in the insulation industry for over 20 years. Specializing in spray foam. Spray polyurethane foam (SPF) is a spray-applied plastic that is widely used to insulate buildings and seal cracks and gaps, making a building or home more energy-efficient and comfortable temperature wise. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams, and joints.

SPF is made by mixing and reacting unique liquid components to create foam. The liquids react very  quickly when mixed, expanding on contact to create foam we use to insulate, seal gaps, and form moisture and vapor barriers. Each spray foam type and method of application offers unique benefits. There are three primary types of SPF that can be used for insulation and other specific purposes.

While spray foam is our specialty, we also insulate businesses and homes with Owens Corning fiberglass batts and blown-in loose fiberglass and cellulose. Call us to discuss the pros and cons of each type of insulation and read posts on our blog by clicking on "Learn More" above.

On the Mark Spray foam sprayed our home 

the next day we returned and you couldn't even tell they were there. Except our air conditioner wasn't running as much. Truly professional and kept open communication at all times.
