Energy efficiency of Spray Foam Insulation vs Conventional Insulation
The composition of fiberglass insulation does not stop air from passing through it. On average, more than 30% of heat or air conditioning escapes where fiberglass insulation is installed. If poorly installed, fiberglass can also leave spaces around fixtures, allowing even more heating or cooling to escape.
Spray foam insulation fills all spaces, preventing air from escaping. It acts as an air barrier. Spray foam insulation is significantly more efficient than fiberglass and has a higher R-value.

Why Spray Foam
Spray polyurethane foam insulation is fast becoming the most popular choice of insulation available. It is well-known for being a superior insulation material, it’s the most robust insulating material on the market today and is frequently utilized to insulate a wide variety of residential, commercial, and industrial buildings outperforming the traditional fiberglass insulation.
Spray polyurethane foam is a spray applied plastic that from a continuous insulation and air sealing barrier on walls, roofs, and on all curved surfaces.
Spray polyurethane foam insulation is known to resist radiant heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks and joints.
Benefits of Spray Foam Insulation:
- Prevents air and moisture intrusion
- Improves occupant comfort keeping you cool in the summer and warm in the winter
- Lowers utility bills through reduced energy usage
- Strengthens the building envelope
- Permanent, sturdy, and does not sag
- Keeps out dust, pollen, and bugs
- Reduces airborne sound transfer through floors and walls including home theatres
- Improves indoor air quality
- Works well with more efficient HVAC equipment
- Meets current building codes
There are two main typed of spray polyurethane foam used within commercial and residential construction:
- Open Cell a low density 0.5 lb. foam with an R-value of 3.5 to 3.7 per inch, which is a soft and spongy material is used in internal applications only.
- Closed Cell a medium density 2.0 lb. foam with an R-value of 6 per inch is a harder stronger material than open cell, is an excellent moisture barrier and can be used both externally and internally.
Because spray polyurethane foam is sprayed into place, it can be installed over a wide variety of substrates, including concrete, wood, steel, and most existing roof systems and can be applied on vertical or horizontal surface and acts as a thermal and air barrier filling cavities and blocking any hole that can cause air leakage.
