BEST FOR:  Garage Ceilings/Cathedral Ceilings

Stevens Insulation intalls 1/2 lb "open-cell" spray foam.  The properties of open-cell spray foam are as follows:


  • 25+ yrs on the market - longer than any other foam on the market to date.

  • Uses water as its "blowing/installation" agent (therefore there is no offgassing),

  • Flexible and will never shrink or lose R-value

  • Hydrophobic - will NOT wick/soak up water

  • Can be installed to thicknesses of 12 inches in 1 pass, as the exothermic/heat reaction is mild

  • Fills in every "nook & cranny" even in blind spots or tight joist areas

  • Is soft and easily removed and replaced

  • Allows substrates like limestone and wood to breathe

  • Is a "green" product, and cannot be used on dirt or outdoors

  • Less expensive than 2 lb closed-cell

  • Is also available as a "pour foam" which can be installed in closed walls that have no insulation in them (typical of Century Homes)



Stevens Insulation also installs

"closed-cell" medium density 2 lb spray foam.  The properties of this type of foam are as follows:


  • Very strong, hard, and will add strength to any structure

  • Waterproof and acts as a vapour barrier

  • Excellent outdoor foam and can be installed on dirt, rubble or stone floors

  • Very robust

  • Higher R-Value per inch than open cell

  • Can ONLY be installed in passes of 2-2 1/2 inches as there is a strong exothermic reaction. Foam must be able to cure before another layer is installed

  • Closed-cell foam cannot be installed in tight areas or areas that cannot be seen into, due to the possibility of spontaneous combustion

  • Care as to where it is installed must be taken, as it will trap moisture

  • Most common type of foam because it is the easiest to install

  • Because more than one pass is usually required to achieve R-Value, it is more expensive than open-cell

  • Closed-cell spray foam will offgas for a period of time immediately following installation


Stevens Insulation installs blown-in attic insulation using cellulose and fibreglass products.  The benefits are as follows:


  • Unlike "traditional" batts, blown in material will fill in every "nook & cranny" in an attic, therefore provides extremely efficient insulation results

  • Cellulose can be dense-packed into empty wall structures

  • Due to its density, cellulose is an excellent air blocker

  • Cellulose also contains "borate" - a naturally occurring product which performs as an anti-vermin agent as well as a fire retardent.

  • Gaining popularity  are "hybrid" attics, where an initial layer of spray foam is installed to create the air seal/air barrier/initial levels of insulation (either cellulose or fiberglass) is then blown in on top, to meet  a building code of R50. 

  • Cellulose and Fiberglass do not perform to the same level as spray foam, but as insulators they have great track records, and are the least expensive of all the insulation products on the market today.​

DC315 is a CCMC approved Thermal Barrier (Fire Protection) that must be installed over any spray foam used as INDOOR insulation.  This product is installed with an airless paint sprayer, and has a flat, white finish.  DC315 can also be used in place of drywall, if you are insulating a part of the home that does not require a "finished" look, such as a crawl space or garage
