Making the choice of what type you should go with actually comes down to what will work best for your project and individual needs.

Closed vs. Open Cell Spray Foam Insulation for Your Grow Room

You may assume that open cell spray foam will outperform the other or the other way around. However, that isn’t the case when it comes down to closed cell and open cell.

It is more about what product is an ideal fit for your grow room and your needs. Here are several advantages and disadvantages that can help you decide:

Disadvantages of Closed Cell Spray Foam

  • Closed cell spray foam is a more costly choice compared to the other type of spray foam.
  • Since water cannot move through it, closed cell will hide a leak if there’s one in your grow room.
  • In addition to that, closed cell is a material that’s much heavier. Thus, it might not be an ideal fit for the exposed ceiling of a grow room.

Advantages of Closed Cell Spray Foam

  • Closed cell spray foam has a built-in vapor barrier.
  • Open cell and closed cell as well do not serve as a food source for pests. Also, the air seal that the foam insulation produces can make it hard for pests to get inside the grow room since they cannot find a way inside.
  • In addition to that, closed cell generates an air seal that can help control the environment required for your plants to grow.
  • Because of its density, water isn’t able to move through closed cell spray foam.
  • It’s an ideal fit for grow rooms with exposed walls since this is a dense material.

Disadvantages of Open Cell Spray Foam

  • If it is knocked into, the open cell can get damaged if the walls of the grow room aren’t covered.
  • Open cell is permeable to moisture. This means it enables water to move through it. Several brands available can keep that moisture.
  • This type of spray foam doesn’t have a vapor barrier built into it.

Advantages of Open Cell Spray Foam

  • This material is lighter and has a high expansion rate. Thus, it can fill every nook and corner of the room.
  • It utilizes water as a blowing agent. Thus, it’s an eco-friendly choice.
  • It also offers sound dampening properties. Thus, this is ideal for you if you do not want any noise.
