Spray Foam Insulation

Spray foam advantages

  • Excellent gap and crack filling capability.
  • Stops air leaks in addition to providing insulation value.
  • Won’t compress, fall out of place or lose R-value like fiberglass.
  • Closed-cell spray foam is waterproof & won’t absorb water.

Of all the many types of home insulation, spray foam has the competition beat in terms of R-value, resistance to mold and moisture damage, durability, air sealing, and versatility.

Spray foam insulation is more expensive than other types of insulation, but the extra cost is usually justified given the advantages it offers.

To discuss the use of spray foam insulation in your home, talk to your local Dr. Energy Saver dealer today! We have proven results for all of our insulation solutions.

Small, medium & large: Spray foam can be applied from cans, canisters or huge barrels.

One way to understand how different spray foam products are used is to focus on how the material is dispensed (see photos). Inexpensive pressurized cans of “one-part” spray foam are used primarily for sealing gaps and cracks. 2-part spray foam comes in larger containers. With 2-part spray form, it’s necessary to mix separate resin and catalyst compounds at the application nozzle. Combining these ingredients starts a chemical reaction that creates expanding foam. Contractors use small 2-part foam “kits” to air-seal an attic or to seal and insulate ductwork. To insulate an entire attic or wood-framed wall with spray foam, the resin and catalyst compounds are pumped to the application nozzle from 50-gal. drums in a specially equipped truck.

Closed-cell “SPF” is used for big jobs

“SPF” stands for Spray Polyurethane Foam, the main type of 2-part, closed-cell spray foam used by insulation contractors. The large-scale insulation jobs performed by these contractors require special equipment as well as safety gear to protect the installer from chemical fumes during installation. When the foam cures and hardens just several minutes after application, it’s completely safe for as long as it stays in place.

When properly installed, SPF creates a highly insulated building assembly that’s also free of energy-wasting air leaks. To see if spray foam is a wise option for improving your home’s comfort and efficiency, contact Dr. Energy Saver today. Dr. Energy Saver provides Free Estimates for all SPF installations.

Nick Nason completed an insulation evaluation and upgrade at our condo last winter. As a result of his excellent work our heating costs so far this winter are 50% of what they were last winter at this time, despite much colder conditions. In addition to the financial savings the level of comfort has improved tremendously.
