2.0 lb Spray Foam Insulation is a high yield, high quality product that is essential for today's rising energy costs

Achieves an R-Value of 6.5 per inch
Provides dramatic savings in heating & cooling costs
Creates a seamless air barrier
Prevents the growth of mold
Highest cost/output ratio of all the various foam types

2.0 lb spray foam insulation is applied as a liquid expanding 50 times its volume in a matter of seconds. 2.0 lb spray foam is a higher density foam and therefore feels more stiff than lower density foams. It is also important to note that 2.0 lb spray foam has a closed cell structure.

Building Science and The Building Envelope

Building Science is a complex topic of understanding with such topics as:

Understanding R-Values
Attic Ventillation
Air Control and Loss

Building Science is defined as: involving the application of basic knowledge and analysis procedures to the design of buildings. There is a special knowledge and experience required, and such expertise is also beneficial in determining how to correct problems in existing buildings and to explain what went wrong to cause the problem.

R-Values

R-value is a term predominantly used in the building industry to describe the insulation properties of certain building insulation materials. Its use is limited to situations where thermal insulation is achieved by retarding the flow of heat through the material itself rather than reflecting radiant heat away. Although they offer a useful means of comparing the performance of different products, other factors need to be considered in maintaining thermal comfort. R-value is a measure of apparent thermal conductivity, and thus describes the rate that heat energy is transferred through a material or assembly, regardless of its original source.

Attic Ventilation

Attics or roofs can be designed and constructed to be either vented or unvented in any hygro-thermal zone (Map 1). The choice of venting or not venting is a design and construction choice not a requirement determined by the physics or by the building code. The model codes allow both vented and unvented roof assemblies. The applicable physics impacts the design of attic or roof systems as does the applicable building code but neither limit the choice.

Throughout the balance of this paper the terms attic and roof will and can be used interchangeably.

In cold climates, the primary purpose of attic or roof ventilation is to maintain a cold roof temperature to control ice dams created by melting snow, and to vent moisture that moves from the conditioned space to the attic. Melted snow, in this case, is caused by heat loss from the conditioned space. The heat loss is typically a combination of air leakage and conductive losses. The air leakage is due to exfiltration from the conditioned space (often because a ceiling air barrier is not present) and from leaky supply ductwork (often because ductwork located in attics is not sealed) and from penetrations like non-airtight recessed lights. The conductive losses are usually from supply ductwork and equipment located in attic spaces above ceiling insulation (ductwork is typically insulated only to R-6 – whereas ceiling insulation levels are above R-30). Conductive losses also occur directly through insulation, or where insulation is missing or thin.

In hot climates, the primary purpose of attic or roof ventilation is to expel solar heated hot air from the attic to lessen the building’s cooling load .

The amount of attic cavity ventilation is specified by numerous ratios of free vent area to insulated ceiling area ranging from 1:150 to 1:600 depending on which building code is consulted, the 1:300 ratio being the most common.

Control of ice dams, moisture accumulation and heat gain can also be successfully addressed by unvented attic or roof design

Air Control and Loss

All houses and buildings are constantly both losing air and allowing area to enter into the structure through various different locations as seen in the picture to the right. It is important to control this air movement as much as possible by reducing the Air Changes Per Hour or ACH.

Air Changers Per Hour (ACH)

An expression of ventilation rates - the number of times in an hour that a home's entire air volume is exchanged with outside air.

Fiberglass has a 0.7 ACH (70%) vs. Spray Foam Insulation has a 0.1 ACH (10%)
What the above means is that 70% of interior air is lost involuntarily each hour through the building envelope
Using standard fiberglass insulation 17 times a day all of your heating and a/c will be lost vs. 2.4 times a day when using spray foam insulation.

Spray Foam Insulation is the most efficient insulation available today.

With savings of 60% available on your heating and cooling costs there is no comparison. Take a look at the long list of other benefits you can achieve by using spray foam insulation:

Comfort

Spray foam insulation greatly reduces drafting air throughout your house
Create a consistent and comfortable temperature throught your house whether one, two or even three levels

Health

Spray foam provides a dramatic increase to indoor air quality
With the creation of an air tight seal dangerous mold and damaging condensation are no longer a concern
Reduce the infiltration of outside air pollutants and gases

Environment

Spray foam insulation greatly reduces your carbon footprint by lowering your CO2 emissions and conserving energy
The addition of spray foam insulation to your home provides significant structural integrity to withstand high winds
Spray foam contains no formaldehyde or other ozone depleting substances

Value

A house insulated with spray foam will see instant reductions in heating and cooling costs upwards of 60%
Heating and Air Conditioning equipment can be downsized
Spray foam insulation will never sag or settle as is the case with other insulation methods
