What is Green Earth Services spray foam insulation?

Spray Foam is a series of spray-applied polyurethane foam insulation systems designed for residential, commercial and industrial building applications. The liquid polyurethane is sprayed onto surfaces and immediately expands to form an airtight insulation barrier.  Spray Foam offers numerous quality insulation, roofing, and sound absorption systems depending upon your personal needs and budget.

Why is insulation important?

Insulation resists the flow of heat, keeping your home or work place cooler in the summer and warmer in the winter.  A properly insulated building allows for HVAC equipment “rightsizing” which means that less money is spent on initial equipment costs, and more money is saved in the long run as your HVAC equipment does not work as hard to maintain a comfortable temperature.  As energy costs continue to rise, a  superior insulation system is one of the best investments you can make for your home or business.

Why choose Green Earth Services spray foam insulation?

Spray Foam insulation systems are environmentally sound, technologically advanced spray polyurethane foams (SPFs) that create an air tight insulation barrier. Spray Foam superior insulation systems conserve energy, block moisture, reduce noise, and limit the influx of outdoor pollutants and allergens.  All Spray Foam formulas are proprietary, and all products are developed at our own state of the art facility.  As an independent polyurethane manufacturer, Spray Foam implements strict quality controls and ensures that our products contain only the finest chemical ingredients.  Spray Foam is energy smart insulation making your indoor living environment healthier, more comfortable, more energy efficient and more affordable

What areas should be insulated?

Ceilings, walls, attics, floors, and around doors, windows, electrical outlets and lighting fixtures are all areas that should be insulated as they allow for the infiltration and exfiltration of air.

What is R-value?

R-value is the measurement of thermal resistance or the resistance to heat flow. Higher R-value means more insulation efficiency, but “air tightness” is just as important when choosing an insulation product.

Is Green Earth Services spray foam mold and mildew resistant?

Green Earth Services' spray foam products do not sustain fungal or bacterial growth. Green Earth Services repels water and creates an air tight barrier that drastically reduces moisture related problems in your home or work place.

What is the difference between closed cell and open cell foam?

Spray Foam offers both open and closed cell spray-applied insulation systems. Open cell foams are softer, more flexible, and more diffusible than closed cell foams. Open cell foams are excellent air barriers and are highly recommended for sound attenuation. Open cell foams are less expensive than closed cell foams due to their light densities. Closed cell foams are superior insulators and vapor barriers. Due to the light weight to strength ratio of closed cell foams, structural integrity of the building is increased. Closed cell foams exhibit higher insulation properties and greater compression strength than open cell foams.

Is spray foam insulation a good soundproofing material?

Both low and medium (2lb/cubic/ft) density spray polyurethane foam effectively reduce noise from outside sources by sealing cracks and gaps that allow sound to travel through the walls, floors and ceilings into the building. They are less effective against noise caused by vibration.

What is the difference between a vented and unvented attic?

Unvented (conditioned) attics use air-impermeable insulation as a barrier to prevent moisture condensation on the underside of roof decks. Vented attics minimize condensation by allowing the escape of moisture to the exterior by air flow.
