Coastal Insulation can improve comfort and energy efficiency with our insulation services

Rigid foam insulation comes in large panels of varying thicknesses. It’s the best insulation to use on basement and crawl space walls because it doesn’t absorb moisture or attract mold.

Tru-Soft™ cellulose insulation is made from recycled newspaper treated to resist combustion, insects and mold. It’s often blown into attics as an insulation upgrade, but it can also be blown into wall and floor cavities.

Injection foam is specially formulated for insulating wall cavities, cathedral ceilings and other enclosed spaces. With excellent flow and fill characteristics, it can be used where there’s no insulation or where existing insulation isn’t performing adequately.

Spray Polyurethane Foam (SPF) is a two-part, closed-cell spray foam with many uses. It expands when applied, sealing air leaks while also creating an effective thermal barrier. It’s often used in attics and basements.

You don't need a degree in thermodynamics to know that heat always spreads out to fill in where it is depleted. In the wintertime, heat moves naturally from inside to outside. During hot summer months, heat "wants" to go the opposite way, moving inside the house to make spaces uncomfortably hot.

This process will cause your home to be uncomfortable, have uneven temperatures throughout the house, and will increase your heating and cooling costs. However, installing proper insulation can help fix these home energy issues.

As a full-service insulation contractor, Coastal Insulation provides expert home insulation services to improve areas such as walls, crawl spaces, basements, and garages in Old Bridge, Trenton, Hightstown and throughout the surrounding areas.
