Spray Foam

 Open-cell spray foam insulation is soft. The cell walls are broken, and  air fills up all of the open space inside the material. Open-cell  typically comes in a .5 lbs/cu.ft. density. The advantage of this lower  density is that it provides an economic yield, making it about half the  cost of closed-cell foam insulation.

 Expands to 120x it's original size. 

 Water passes through it, making it easy to detect leaks in the roof line.

 Excellent noise reduction - about twice as effective as closed-cell foam. 

   Typically comes in .5 lb per cubic foot.

 Provides economic yield and is about half the cost of closed-cell foam insulation.

 Open-cell foam is used in a wide range of applications, such as for  noise reduction in sound rooms, home insulation, metal buildings, under  roof deck for semi-conditioned attics, and more. 

 Closed-cell spray foam insulation is highly efficient. This structural  insulation makes for an incredibly effective air barrier, and with its  low moisture vapor permeability, it’s highly resistant to water. Its  density is typically 2 lbs/cu.ft. Closed-cell foam also offers one of  the highest R-values (resistance to heat flow) of any insulation on the  market. 

 Increases structural strength by up to 200-300x 

  Can be left exposed without risk of damage.

 Only FEMA-approved insulation type.  

 Incredibly effective air barrier and highly resistant to water. 

Offers one of the highest R-values (resistance to heat flow) of any insulation on the market.  

 Common applications for closed-cell insulation include wine rooms, metal buildings, containers, and cold floors.

 To prevent these problems from occurring in your crawl space, it’s  recommended that you have a crawl space vapor barrier installed as soon  as possible. A vapor barrier is a type of crawl space insulation material that specifically protects your crawl space and other areas of your property from water and moisture.

The vapor barrier blocks moisture from entering the crawl space and  prevents water damage from developing in the area. It also has the  ability to provide you increased energy efficiency by controlling the  amount of heat that penetrates and escapes your home. Additionally, the  crawl space vapor barrier protects your utilities (e.g. pipes) from  getting damaged.

 Areas like your crawl space are susceptible to encountering moisture  damage. When it floods, rains, or the temperature drops, water enters  the crawl space and stagnates. If this happens to your property, your  top priority is to remove every trace of water and keep the area  completely dry, because, if you leave the crawl space damp, the  following problems will arise: 

• Putrid odors
• Mold and mildew growth
• Soft and separating floors
• Water-loving insect, vermin, and critter infestation
• Premature decaying of organic material (e.g. wood and rust)

 Crawl space insulation, as a part of overall home air sealing and insulation, helps maintain your entire home's energy efficiency. Without insulation, heat and cool air are easily lost through the floor. Insulation also helps to preserve the air quality and reduce energy costs. 

  insulating the attic can save 10 to 50 percent on a typical heating bill. ... For many homeowners, insulating the attic is the most effective method to save on energy costs.
