What is bio foam insulation?

BioFoam® is a new, patented foam that is comparable to EPS (expanded polystyrene). It looks similar in structure and has more or less the same properties as EPS. The major difference is that EPS is made of polymers that are based on fossil raw materials (a finite resource).

What is BioFoam made of?

BioFoam® is a patented biological foam made in the United States from vegetable materials, such as corn, sunflower seeds, castor oil beans, and soybeans. BioFoam received a Cradle to Cradle® Certification™, a globally recognized measure of safer, more sustainable products.

What are the disadvantages of closed cell spray foam?

Below we are going to list the most common problems with using spray foam insulation in your home’s attic or in any area inside of your home.

  • Placement Errors During Installation.
  • Potentially Attracts Water Damage.
  • The Material May Shrink Overtime.
  • Long Dry and Cure Time.

Which spray foam insulation is best?

Closed cell foam is the best choice for robust insulating where space is an issue, as it can achieve 2x the R-Value of open cell inside a standard wall. Its rigid nature also adds to the structural integrity of the building and E84 fire rated versions are available.

Is BioFoam toxic?

Earlier, in 2009, as the first foam to do so BioFoam already received Cradle-to-Cradle Silver certification, as well as a material health certificate stating that it is free of CMR substances (substances classified as carcinogenic, mutagenic, or toxic for reproduction) from Michael Braungart’s Environmental Protection …

How do you make BioFoam?


  1. Gelatine powder – 12 gr. Functions as the polymeer (makes it hard)
  2. Glycerine – 12 gr. Functions as plasticizer that bonds with the gelatine (makes it flexible)
  3. Water – 150 ml/gr. To dissolve and mix the polymeer and plasticizer.
  4. Dishwashing soap (organic) – 1 tsp. Is the expanding agent that makes the mixture foamy.

Why do lenders not like spray foam insulation?

So why is it a problem for mortgage lenders? By sealing the roof space with this material, air circulation can be restricted to the roof and timbers. This can lead to condensation, which in turn can eventually lead to the rotting of the wooden roof supports.

  3. Open-cell spray foam on your roof:
  4. For closed-cavity spaces:
  5. If you have a history of skin, respiratory, or asthma problems:

What is the R-value of 2 inches of spray foam?

R-Value In 2 Inches Of Spray Foam The R-value ranges from R-3.5 to R-3.6 per inch. The filling of a 2×4 cavity yields about an R-13.

Is 2 inches of closed cell foam enough?

Closed cell spray foam should be 4- to 5- inches on the ceiling and 2- to 3-inches in the walls. This might come as a surprise to you, but honestly, this is all the spray foam it takes to get the biggest bang for your buck with the air seal and thermal resistance needed for certain areas of the home.

Is BioFoam biodegradable?

Biodegradable. Since BioFoam® is organic, it can be reused in a closed-loop. It’s also biodegradable and can be industrially composted at high temperatures.

Is petroleum based foam safe?

Both Polyurethane Foam and Memory Foam are petroleum-based. First, that means they are made with a “witches brew” of toxic chemicals (more on that soon). Second, they break down over time, causing major off-gassing of VOCs into the air you breath. And third, they are extraordinarily flammable.
