Is Open Cell or Closed Cell Foam Insulation Better for My Home?

If you’re looking for spray foam insulation Scarborough, you need to know which type would be more ideal for the application you have in mind. The best one for your home depends on which areas and rooms you want to insulate. Each type, closed cell and open cell, has its uses and advantages. Some areas of the home require thicker and denser insulation than others. Factors such as moisture and sound should also be considered.

Here is a look at each type of spray foam insulation and the ideal places it should be used.

Open Cell Foam Applications

Polyurethane spray foam of the open cell variety is found in lower densities and has a lower R-value. It’s often referred to as “half pound foam” due to its average density of .5 lb per cubic foot. Due to its lower density, it is not ideal for external applications.

A few places where open cell would be preferred over closed cell include:

  • Any room that requires soundproofing. This could be a family room, music or multimedia room, laundry room, etc. Think of all of the noises that travel through the walls, coming from appliances, televisions, gaming systems, stereos, talking, running water, etc. Open cell spray foam is the ideal solution for muffling out these sounds, as it seals the way around the sources.
  • Any area with wood construction. Open cell spray foam works better with wood, as both materials act as barriers that can not only absorb moisture when required, but release it moisture as well. Closed cell foam, in contrast, tends to block moisture, which can cause a buildup.
  • The underside of a roof deck. If your home requires a conditioned attic assembly, this might be the ideal move. The air impermeability of the open cell foam helps to increase the performance of the HVAC equipment in the attic, which results in reduced energy consumption and costs.

Closed Cell Foam Applications

Since it’s denser and stronger, closed cell polyurethane foam can be used outdoors as well as indoors. It also has commercial use. The average R-value is 6 per inch, although the number can go over 7 per inch.

The close cell variety of foam can be use in any application requiring structural support and strength. Ideal areas of your home include:

  • The walls. It can be applied to just about any wall in the home, including those requiring nonstructural thermal insulation materials. Ideal substrates include any foam sheathing, oriented strand board, plywood, and primed or painted steel.
  • In the basement. Its strength helps to prevent the growth of bacteria and mold. For this reason, closed cell foam spray is ideal for basements, cellars, or any other part of the home that is susceptible to the spread of bacteria and mold.
  • Exterior applications. Don’t forget about the outside of your property when it comes to insulation. In addition to cathedral roofs, closed foam spray can be used on garage ceilings, pool decks, exterior walls, etc.

Whether closed or open spray foam would be ideal for your home depends on where exactly you need insulation and how much of it is required. You might even find a combination of the two to be ideal for your Scarborough home.
