Open-cell spray foam is a type of insulation made from a polyurethane-based material that expands after application. It has a sponge-like texture, allowing air movement while still providing thermal insulation and sound dampening.
Open-cell foam is softer and less dense than closed-cell foam. It has a lower R-value per inch but offers superior sound absorption and is more cost-effective for interior applications where moisture resistance is not a primary concern.
Open-cell spray foam typically has an R-value of around 3.6 to 3.8 per inch. This rating measures its resistance to heat flow, with higher values offering better thermal performance.
It is best suited for interior walls, attics, ceilings, and other areas where vapor barriers are not required. It should not be used in locations exposed to high moisture or direct water contact.
No, open-cell spray foam is not a moisture barrier. Its porous structure allows moisture and vapor to pass through, which can be beneficial in some attic and wall applications but unsuitable for basements or damp environments.
Yes, once fully cured, open-cell spray foam is inert and does not emit harmful gases. Installation should be done by professionals with proper ventilation to allow for safe curing.
Installation usually takes one to two days, depending on the size of the area and accessibility. The foam cures within a few hours but should not be disturbed until fully set.
Typical applications involve 3 to 5 inches in attics and 3.5 inches in wall cavities. The thickness depends on the required insulation performance and local building codes.
Yes, its open structure absorbs sound waves, making it effective for soundproofing between rooms or floors in residential and commercial buildings.
Yes, it helps reduce energy bills by sealing air leaks and maintaining consistent indoor temperatures, though it may need to be combined with other materials in extreme climates.
When properly installed, it can last for the life of the building. It does not sag or settle over time, maintaining its insulating properties for decades.
It is generally recommended to remove old insulation before applying spray foam to ensure full adhesion and effective sealing. Mixing types can limit performance and introduce moisture risks.
No, it does not attract insects or rodents. It does not contain food value, and its solid application can reduce the entry points pests use to enter a structure.
Costs vary based on project size and location but typically range from $0.40 to $0.60 per board foot. It's more affordable than closed-cell foam and competitive with other insulation types over the long term.
Yes, most local codes have requirements related to flame spread, thickness, and vapor barriers. A professional contractor will install according to these regulations.
In many climates, yes. Since it allows moisture vapor to pass through, an additional vapor barrier may be needed depending on local code and installation location.
DIY kits exist, but professional installation is strongly recommended. Proper application requires specialized equipment, experience, and safety measures to avoid issues like improper curing or off-ratio mixing.
