E:500 open-cell NSAI Agrément Certified Spray Foam

Commitment to Sustainability and Saving Money

E:zero embodies a commitment that addresses one of the biggest challenges of today: zero carbon emissions. E:zero's mission is to offer money-saving products that provide the 21st century with comfort, while helping save the planet. E:zero Foam Solutions contributes to the first step in the right direction: a 50 % reduction of your carbon footprint. E:zero stands for going green and saving money in a single step.

How does it work?

E:zeros E:500 insulation foam is spray-applied on the job site. As it is sprayed, it increases in volume up to 100-120 times, providing a fully adhered, continuous, solid, and airtight insulation layer. Even the most minuscule cracks are perfectly sealed. Because it is sprayed, the foam fits all shapes, corners, and cavities perfectly. The results:

  • insulation and perfect air seal in a single application
  • lower u value per inch of application thickness
  • seven times better air seal compared with traditional insulation
  • elimination of unplanned air-borne moisture movement and related condensation
  • energy savings of about 50% compared with conventional insulation

E:500 soft spray insulation foam can be applied anywhere fiberglass was traditionally installed. By replacing fiberglass, home owners get to enjoy improved energy efficiency and greater comfort of spray foam, while avoiding the shortfalls of fiberglass, from its carcinogenic nature to mold susceptibility.

Lifetime performance

Good news for your wallet and the planet: E:zero insulation foam will perform for the lifetime of the building and will never need replacing or restoring. Think of E:zero spray foam as industrially-produced wood. No trees were chopped down and ultimately, huge amounts of energy are being saved for centuries. Every bit of energy savings translates directly to an avoidance of CO2 emissions.

Product Benefits

E:500 and E:2000 both offer a diverse range of benefits not only to the homeowner, builders, contractors, and architects, but to our environment as well. There are five vital and key benefits of E:zero's spray foam insulation:

Open-cell Technology Explained

When observed under a microscope, open-cell foam looks like a web with the tiniest of pathways. These pathways form as a result of the high expansion rate, and there are numerous benefits associated with this technology. While the pathways are small enough so the foam presents an effective air barrier, these lanes still allow the structure to breathe. Technically, the foam is a thermo-set, rigid plastic; however, the very low density makes the foam semi-flexible, which is an advantage in regions vulnerable to earthquakes. The insulation will not crack if the building is shaken. Environmentalists appreciate that the foam is water-blown, meaning the cells are formed by reacting water which forms CO2. Accordingly, E:500 has a very high percentage of renewable contents and is an effective vapor retarder, suitable for insulation in all but the most extreme climates. The product is not suitable for insulating rooms with excessive interior moisture levels, such as indoor pool areas or indoor hot tub areas. Also, in case of strong, unidirectional vapor drive, such as in commercial cold storage or wine cellars, we recommend using the E:2000 solution, which is a high density foam made by E:zero, engineered to be compatible in mixed applications.

"Hydrophobia" - A misleading claim

Several of E:zero's competitors claim that their open-cell foams are "hydrophobic", implying that their foam will perform well at any moisture level. In our technical opinion, these are misleading claims. None of the open-cell foams, including ours, provide effective vapor barriers, or water-proofing. If you require a vapor barrier, you must use a foam that has been properly rated as a vapor barrier, such as E:zero's closed-cell E:2000.

Recommended Application Areas for E:500

Recommended Not Recommended
Above ground wall insulation (residential and commercial) Yes
Inside attic insulation - unvented Yes
Inside attic insulation - vented Yes
Bathrooms, kitchens, etc. Yes
Basement walls No, unless very dry
Crawlspaces/raised foundations No, unless very dry
Indoor pool or hot tub No
Wine cellar or commercial cold storage No
Extreme cold climate No

The E:500 soft insulation foam will perform better than a fiberglass product in every aspect; from mold prevention to moisture intrusion and energy efficiency, to health, sound, comfort, and environmental perspectives. Since E:500 is first spray-applied and then expands, excellent air-tightness is "built" into the product. Spray application avoids air pockets between the outer building envelope and the insulation, eliminating condensation and related mold problems. This is also true for overhead application like vaulted ceilings: the foam reacts fast enough that it will fully adhere to the roof deck or whatever substrate exists, and eliminate the cavity in which condensation may occur.
