Spray Polyurethane Foam

Spray Polyurethane Foam

Indoor environments need airtightness to be comfortable. For completely sealing off a tight space and providing the highest possible levels of thermal resistance, spray foam is a viable solution.

Also known as Spray Polyurethane Foam (SPF) and Injection Foam, spray foam creates a hermetically sealed barrier wherever it is applied.

To create SPF, technicians use machinery whose controls and fuel source are mounted to a truck. The machine combines and heats a special mix of chemicals, and uses a hose to deliver the resulting material in the form of aerosol gases (which solidify upon application). A spray gun is used to ensure accuracy.  

Spray foam insulation is used to fix even the smallest leaks in roofs, attics and ceilings. No gaps are left for heat, cold, moisture and airborne particles to pass through.

Where walls have been fitted with electrical boxes, wiring, ventilation fixtures, and plumbing, insulation batts are too troublesome to cut and fit. Coverage of these areas with batts is limited and frankly, ineffective. Spray foam insulation is capable of filling holes, cracks and cavities in hard-to-reach places. 

Benefits of Spray Polyurethane Foam:

  • Spray foam has a higher R value than all other forms of insulation
  • Quick installation when performed by technicians
  • Spray foam insulation has sound deadening abilities, especially in open-cell form 
    • Noise carried between rooms as well as from the outside, is reduced 
  • Protection against moisture, as well as consequent mold and mildew
    • In other words, SPF is waterproof
  • Fire resistance
  • Protects the house against pests and rodents
  • Year-round energy savings
    • Since spray foam does not degrade over time, cost savings are realized year after year!  

    Typically, customers choose between open cell and closed cell spray foam insulation, or a combination of the two. Each has its own unique properties…  

Open Cell Spray Foam 

  • Also referred to as half-pound, low density foam
  • Soft, spongy texture once applied
  • Carries a Resistance value of R2.2 to R3.5
  • Expands up to 10 times its original size upon spraying 
  • Vapor-permeable but resists air penetration
  • More cost-effective than closed cell
    • Use is limited to interior applications, where airtightness and moisture are not primary concerns

Closed Cell Spray Foam

  • Also referred to as two-pound foam, medium density foam
  • Solid, rigid texture once applied
  • Carries a Resistance value of R6 to R7
  • Shields interiors from outside air, prevents drafts and helps maintain room temperature
  • Provides structural reinforcement for your home
  • Protects against water penetration and degradation
  • For both interior and exterior application
