Explore our product options and see how we can help you create a healthier, more efficient property.
Open Cell 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.
- Expansion: Expands to 120x it’s original size.
- Leak Detection: Water passes through it, making it easy to detect leaks in the roof line.
- Noise Reduction: Excellent noise reduction – about twice as effective as closed-cell foam.
- Low Density: Typically comes in .5 lb per cubic foot.
- Low Cost: 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 Foam
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.
- Strength: Increases structural strength by up to 200-300x
- Durable: Can be left exposed without risk of damage.
- FEMA Approved: Only FEMA-approved insulation type.
- Efficient: Incredibly effective air barrier and highly resistant to water.
- Heat Resistant: Provides economic yield and is about half the cost of closed-cell foam insulation.
Common applications for closed-cell insulation include wine rooms, metal buildings, containers, and cold floors.
Vapor Barrier
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)
