Insulation Services

With so many options of insulation out there we have made the below list to help you choose which product would be best for you. If you have any further questions please feel free to contact us here.

Fiberglass Batting Insulation

Fiberglass Pros:

  • Relatively cheap
  • Doesn’t require any special installation tools
  • Easy to transport using a standard pickup truck
  • Can be installed by hand in a single day
Fiberglass Cons:

  • Doesn’t provide great R-value (about R3 / inch)
  • Susceptible to mold in certain conditions
  • Doesn’t fill every nook and cranny of the walls, leaving gaps for air to circulate, which ultimately contributes to energy loss. These air gaps are not considered in the reported R value of the insulation, making the effective R value much lower.

Wet Cellulose Wall Insulation

Wet Cellulose Pros:

  • A sticky cellulose product sprayed into the stud walls
  • R-value is slightly higher than fiberglass at about R4 / inch
  • Fills the cracks and voids that fiberglass batting leaves open
  • Highly fire resistant and eco-friendly
  • Slightly more cost-effective solution than spray foam products
Wet Cellulose Cons:

  • Higher cost than fiberglass
  • Requires special installation tools
  • Entails a somewhat “messy” installation
  • Still susceptible to mold in certain environments
  • Does not offer as tight a seal as spray foam products.

Spray Foam Insulation: Open Cell Insulation

The third and fourth options up for consideration are spray foam insulation products. I’m starting with open cell insulation because it’s less expensive and not the option we ultimately chose. That said, open cell insulation is a good product that can be very cost efficient for many installations.

Open cell spray foam insulation is a chemical product that is sprayed onto the wall and then expands to fill the space. The term Open Cell refers to the cell structure of the resulting foam, which cures to a sponge-like material with millions of tiny open bubbles. The consistency is similar to angel food cake. The chemicals are mixed on site using a special compressor and gun system. The compressor may heat the foam to a required temperature. When sprayed on the walls, the foam sticks and expands in place.

Open Cell Foam Pros:

  • Expands to 100 times its spray-on size to fill the space and voids
  • Creates a better seal than spray cellulose
  • Provides a comparable R-value in most installations
  • Can be sprayed blindly to fill the space of a cavity
  • Relatively cost efficient
  • Stays somewhat flexible, which is good for ensuring flat drywall installation.
Open Cell Foam Cons:

  • Does not provide as tight a seal as closed cell foam because it’s filled with air
  • Less energy efficient than closed cell products
  • Near half the insulation performance of closed cell products

Closed Cell Spray Foam Insulation

Closed cell spray foam is very similar to its open cell counterpart, with the exception that the bubbles in closed cell foam are ‘closed’ and so do not permit any air flow. You can think of closed cell foam as a very tight honeycomb of closed cells that are waterproof and air tight.

Closed cell foam can come in a range of different cured hardnesses, all the way up to foam that can support human weight. Closed cell spray foams can also be designed so that they cure with bubbles filled with non-air chemicals that improve energy efficiency.

Closed Cell Foam Pros:

  • Offers very high R-values (R7 per inch!)
  • Completes the building envelope and tightly seals gaps to prevent air flow
  • Highly mold resistant
  • Provides a vapor barrier for the installation
Closed Cell Foam Cons:

  • Best performed by a professional installer
  • Significantly higher price than fiberglass

    Alternative Insulation Methods

    There are more insulation options than what we’ve listed here, including hybrid installations (e.g., closed cell foam topped with fiberglass), and installations of rigid foam board, etc. We’ve covered all the common options here; and hope you find it a good reference.
