What is the difference between open & closed-cell spray foam?
When it comes to spray foam insulation, selecting the right product for the application is important. The advantages of open cell foam compared to those of closed cell foam can make a difference in how your building performs throughout the year.
Both closed cell spray foam and open cell spray foam insulation can be used effectively in commercial building designs to allow the building to achieve energy efficiency and consistent performance. When applied on the interior, open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior. Architectural firms can specify both the building envelope for a total performance option.
Closed cell is a medium density, rigid spray foam with a higher R-value (resistance to heat flow) per inch. Ideal for continuous insulation applications in commercial buildings, suitable for small spaces requiring the highest R-value possible (such as crawlspaces) or where bulk moisture or flooding is an issue. In fact, FEMA recognizes closed cell foam as a flood-resistant material.
Open-Cell Spray Foam
-
Can be installed at a significantly lower cost and target the same specified R-value
-
Can achieve greater R-value if not restricted by space
-
Lower raw material/resource use
-
Permits bi-directional drying
-
Will accommodate long-term creep and seasonal movement
-
Hydrophobic material
-
Air barrier and insulating material
Closed-Cell Spray Foam
-
Can be applied at very low temperatures (as low as 5oF)
-
Adds wall racking strength as well as impact resistance
-
Ideal for continuous insulation solutions
-
Higher R-value* per inch – easier to accommodate high R-value* requirements in narrow spaces
-
Lower vapor permeance (can be a Class II VDR)
-
Can reject bulk water (ideal for flood zones)
-
Higher tensile and bond strength
Advantages of Patriot Foam
& Coatings Wall Foam
Compared to traditional insulation products available on the market, Patriot Foam can help reduce heating and cooling costs by up to 50%. As a thermal insulation and air barrier material, Patriot Foam can help achieve optimal air-tightness without using labor-intensive sealing materials. Additionally, with Patriot Foam insulation, heating and cooling performance can be optimized with right-sized HVAC equipment.
ENERGY EFFICIENT
Minimizing indoor air pollution helps promote good health, comfort and productivity. Patriot Foam insulation helps minimize indoor air pollution by delivering a continuous thermal barrier that completely seals around plumbing, vents and electrical openings as well as gaps and cracks that allow unwanted air leakage. Patriot Foam helps minimize airborne irritants such as allergens, drafts or humidity. When combined with proper mechanical ventilation, Patriot Foam allows occupants control of the quality of the indoor air.
INDOOR ENVIRONMENT
According to the U.S. Department of Energy, air leakage can contribute to as much as 50% of a building’s energy loss. Building science experts recognize that controlling air leakage, complemented by a reasonable R-value level, will have a greater impact on energy conservation than R-value alone. Patriot Foam spray foam insulation products are classified as air barriers to help stop air leaks and help save energy, control airborne moisture, enhance durability and provide comfort.
AIR LEAKAGE
Patriot Foam insulation delivers advanced moisture management by forming an air seal that helps minimize air movement. By minimizing airborne moisture transported through the building envelope, Patriot Foam helps to prevent condensation and the resulting potential for mold growth within walls and ceilings. Patriot Foam light-density spray foams are formulated to allow them to dry and remain unaffected should minor wetting occur. This allows the foam to continue functioning at optimal levels. Open-cell technology helps in the identification and diagnosis of leaks and in protecting roof decks from sustained wetting/conditions that can lead to rot. It is also helpful in drying moisture trapped in adjoining materials. Patriot Foam light-density spray foams allow these materials to dry over time, minimizing the potential for damage.
