About Us

Since 2015, 1st State Insulation LLC has been providing our customers with insulation services – and education – that make a difference. Whether it’s fiberglass or mineral batts, we work closely with builders, homeowners and commercial contractors to identify the best solutions for their needs. Not only are we helping them to cut down energy consumptions and cost, but we are giving them the confidence of protection against moisture and heat damage.

The core value that drives our business is customer education. When a builder wants to invest in preventative energy measures, or when a homeowner wants to increase his home’s efficiency and safety, we treat each customer with honesty and respect by educating them on what they do – and don’t – need for their project.

In 2019, we joined the Installed Building Products Family of Companies, which has supported us as we continue to provide superior insulation products and personalized, on-demand support to builders and homeowners in Delaware, Southern New Jersey, Eastern Pennsylvania and Maryland’s Eastern Shore.

Whether you’re looking to invest in comfort and savings for your home, for outstanding thermal and acoustical performance that maximizes LEED ® credits for your building, or need answers on what insulation is best for each part of your new build, 1st State Insulation is ready to deliver what you need.
