Spray foam roofing and spray foam insulation are two of the materials that are used for insulation purposes. Many homeowners tend to get confused about these two, and wonder whether the two are similar or different. Read on and find out.
Spray Foam Roofing Vs Spray Foam Insulation
Spray Foam Roofing, or Spray Polyurethane Foam Roofing, is a type of material which is sprayed in the form of a liquid. Upon contact with a surface, the liquid can expand into foam. A solid layer is created across an already existing roof. It is possible to use a Spray Foam Roofing system in any climate. When installed in a proper way and maintained correctly, it can last for more than 50 years. Spray Foam Roofing is used to insulate loft and roof spaces.
Spray Foam Insulation offers effective sealing against outside air. It is composed of a blend of isocyanate in foam and polyol resin. It can be found in two varieties, a) Open-Cell and b) Closed-Cell. The Closed-Cell variety has foam cells pressed together - which offer superior prevention of the entry of air and moisture. Thus, there is better insulation due to the use of the Closed-Cell variety of Spray Foam Insulation.
The Open-Cell variety is better for areas with less harsh climate and more comfortable temperature conditions. Spray Foam Insulation can last for over 80 years after installation. Unlike Spray Foam Roofing, Spray Foam Insulation can be used almost anywhere. It is commonly used in spaces like basement, loft and attic.
Spray Foam Roof Insulation Problems
According to experts, there can be various Spray foam roof insulation problems arising when an untrained or unlicensed contractor applies spray foam insulation in a poor way. It can lead to several issues, such as:
- Lack of adhesion
- Bad odors
- Off-ratio spraying of the material
When this happens, there can be a permanent odor in the space. Keep in mind that if you have a medical history of asthma, respiratory issues or skin problems, it would be a better idea to skip it altogether.
Features of Spray Foam Insulation
Spray foam insulation blocks convective, radiant and conductive heat transfer. This makes it perfect for ensuring comfortable temperatures in rooms. As compared to traditional insulation, it can insulate as much as 50% better.
When you go for spray insulation, you can be assured that it can block sound, deter moisture, reduce the need for energy usage and improve the quality of indoor air. Spray foam is known to be eco-friendly, and can be installed in an easy way. That said, it is better that you avoid undertaking this kind of task as a DIY project. Improper insulation has many disadvantages, and thus, it is important to avoid a DIY job if you lack the knowledge, expertise and training to carry out the installation in a proper way.
Spray foam insulation is a costly project, and although the Open-Cell variety is cheaper than the Closed-Cell foam variety, both types can set you back by a few thousand dollars – if you have a wider area to cover. But it is true as well that you can find this a worthwhile expense – given that you can be assured of better insulation and air-sealing when you make this investment. There can be more comfort and spray foam reduction in energy expenses.
