Liquid Green installs both major types of spray foam insulation, plus dedicated residential and commercial service lines. Pick the application that matches your build — every installation is engineered for the structure, not off the shelf.
Open Cell Foam
Lightweight, expanding insulation ideal for walls and attics. Provides excellent sound dampening and air sealing at a lower cost per board foot.
Open Cell Details →
Closed Cell Foam
Dense, rigid insulation with the highest R-value per inch. Adds structural strength and acts as a built-in vapor barrier — the right pick for exterior walls and basements.
Closed Cell Details →
Residential Insulation
Whole-home spray foam for new construction and retrofits — attics, walls, rim joists, crawl spaces. Lower energy bills, eliminate drafts, and quiet the house.
Residential Services →
Commercial Insulation
Large-scale spray foam applications for warehouses, retail, agricultural, and industrial facilities. We mobilize crews and equipment for projects of any size.
Commercial Services →
Energy Savings
Lower heating and cooling costs by up to 50%. Spray foam seals the building envelope so your HVAC runs less and your home or building stays at a stable temperature.
Why It Saves Energy →
Mold & Moisture Control
Spray foam prevents airborne moisture across the building envelope — one of the main causes of mold. Closed cell acts as a full vapor barrier.
Moisture Control Details →Tri-State Spray Foam Insulation Experts Since 2010
We have created many strong believers in spray foam insulation throughout our years in business. Commercial building owners as well as residential homeowners throughout the tri-state area are reaping the benefits of being built with spray foam insulation. Most builders that we work with today tell us that they continue to use foam because they have seen it makes a difference. They know the value that it adds to a structure, and the comfort and savings it will provide for years to come.
Spray foam insulation in both commercial and residential construction offers both immediate and long term benefits. It can lower your heating and cooling costs by up to 50%, reduce the chance of mold growth, discourage infestation of household pests, improve air quality and protect against respiratory problems by reducing allergens, pollutants, and pollen. Spray foam insulation will also increase the resale value of your home, and even reduce external noise pollution. These short and long term benefits far outweigh the cost of initial installation and will keep you and your family comfortable in your home for many years to come.
Benefits of Liquid Green Spray Foam Over Conventional Insulation
Superior Thermal Performance
Spray foam provides the highest R-value per inch of any insulation material, keeping your home warmer in winter and cooler in summer. Learn more about R-value →
Optimal Air Tightening
Unlike fiberglass, spray foam expands to fill every gap and crack, creating an airtight seal that stops drafts and energy loss. How the air seal works →
Enhanced Sound Control
Spray foam significantly reduces noise transmission between rooms and from outside, creating a quieter living environment. Sound dampening details →
Moisture Resistant
Liquid Green spray foam far exceeds fiberglass or cellulose in moisture resistance and helps prevent mold growth across the building envelope.
Class 1 Fire Rating
Our spray foam is not a fuel source and offers a Class 1 fire rating — the highest rating for building insulation. See fire-rating specs →
No Food for Pests
Liquid Green spray foam has zero food value for rodents and insects, making it a pest-resistant insulation choice.
