Common questions about Spray Foam Insulation

Spray Foam Insulation is a two part chemical composition that is mixed upon application, which then becomes foam insulation. It can be applied to plywood, OSB, cinder block, poured foundation, metal framing, and much more. Once it expands into place it becomes an energy efficient air and vapour barrier (if applied to manufacturer specifications). Spray Foam provides a complete seamless building envelope, and creates a more comfortable environment for the life of your home.

What is the difference between Open-Cell and Closed-Cell Spray Foam Insulation?

There are two types of spray foam: open-cell (isocyanurate) ½ pound foam, and closed cell (polyurethane) 2lb foam.

The closed cell foams typically have a higher R-value than open-cell foam. Sprayed foam insulation is applied as a liquid that contains a polymer (such as polyurethane or modified urethane) and a foaming agent. The liquid is sprayed through a nozzle into wall, ceiling, and floor cavities where it expands to fill every nook and cranny. Because it expands into tight areas, sprayed foam is ideal for insulating steel framing and around outlets. By acting as a wind and air barrier, it often eliminates the need for separate air-tightness detailing, which can increase energy efficiency and allow downsizing of the heating and cooling system equipment.

Open-Cell half pound foam is incredibly effective as a sound barrier. It maintains its performance with no loss of R-Value over time. It also maximizes air leakage and seals the buildings envelope to optimal air tightness. Closed-Cell polyurethane spray foam is one of the most efficient insulation materials commercially available. It provides one of the highest R-Values and is a highly effective air barrier with very low moisture vapor permeability. It’s commonly used in tighter spaces.

Sprayed foam insulation does not shrink, sag, settle, or biodegrade. By acting as an air barrier, spray foam insulation provides insulation and air sealing in one step. In addition, most foam insulation products have a higher R-value per inch than fiberglass batt insulation. This increases energy efficiency by allowing downsizing of the heating and cooling system equipment.

Residential Spray Foam Insulation Applications:

Some of the uses for spray polyurethane foam insulation for residential applications include:

  • Walls... both interior and exterior applications

What is Spray Foam Insulation made of?
Spray foam insulation is made of environmentally friendly urethane. Our foam does not have any formaldehyde or asbestos

How is spray foam insulation Installed?
The foam is sprayed by a certified trained installer into the open cavity of walls, ceilings and roof structures after the plumbing and electrical systems are put in place.

What are Spray Foam's Advantages?
Spray foam insulation does more then just insulate. It stops allergens, pollen and any other pollutants from entering your home. Your home will be quieter and the air you breath will be cleaner and more comfortable. Spray foam insulation reduces energy and fossil fuel consumption. It also reduces greenhouse gas emissions. Spray foam insulation remains rigid and does not settle or sag. This means it adds structural strength to a house while adding very little weight. It’s solid by nature, provides sound proofing, is insect resistant and seals cracks from unwanted gas and odor penetration.

Is Spray Foam Insulation a good Sound Proofing Material?
Yes, the half pound foam reduces noise from outside sources by sealing cracks and gaps.
