Leading Developers in Polyurethane Foam


What happens when you mix isocyanate and polyol resin? You get a chemical reaction that makes Spray Polyurethane Foam or SPF. This spray foam is excellent for different applications like packaging and insulation.

SPF is available as either open cell or closed cell types (based on cell structure). Each type has its own benefits and drawbacks depending on what you require as a business or a homeowner.

In This Article

  • Open Cell and Closed Cell SPF Types
  • Foam Choice: Factor in project type, budget, insulation needs.
  • Isothane: Leading developer in polyurethane foam.
  • Applications: Wall insulation, roof protection, movie props, marine buoys, waterproofing.
  • Products: Ecofil 40 for buoys, Technitherm for walls, Pirthane® 0 is fire-resistant, Thermadek for roofs, Isothane WBF for soundproofing.

Open Cell

This type has space between the cells, so it’s softer and pliable. This makes it very useful to be used in spaces that are hard to reach or small. It has a lower R-value, which is a measure of thermal resistance, or a value that shows how well a material insulates. This type is usually less expensive compared to closed cell. Sometimes, it helps that this type allows for more air circulation, but there’s a downside, that it may retain water or moisture.

Closed Cell

In this type, the cells are more densely packed, making it more rigid and stable. It even has a higher R-value per inch which makes it much better for insulation, though more expensive than open cell. It can be used as a barrier against moisture, protecting structures from water damage, in fact, it makes the building stronger. This type is helpful if one is looking to insulate larger areas that want to keep the vapours away.

Broadly speaking, when you choose between either, it’s important to consider:

  • kind of project
  • budget constraints
  • insulation needs
