Polyurethane foam insulation is one of the most effective and popular insulation products available. Fulkrum offers both open-cell and closed-cell polyurethane foam. These two products offer different benefits that allow Fulkrum to customize your installation and optimize the results.
Open-cell polyurethane foam (half-pound foam) produces incredible results:
Controls air infiltration
Reduces exterior noise
Improves indoor air quality
Provides approximately. 3.7 R-Value per inch
Open-cell foam insulation reduces airborne noise and dust, making it a healthy choice for those who suffer from allergies, asthma, or chemical sensitivity. It offers an ideal solution for cathedral ceilings, conditioned attics, wall cavities, and wood and/or steel construction.
Closed-cell polyurethane foam (two-pound foam) offers multiple applications:
Controls Air Infiltration
Improved Indoor Air Quality
Provides a vapor barrier
Delivers approximately 6.9 R-valus per inch of depth
Enhances structural strength
Controls Moisture Infiltration
Closed-cell foam insulation, in addition to its outstanding insulation has shown to increase structural racking strength by up to 300 percent in wall cavities. It is a perfect choice for warehouses, shops, barns, hangars, basements, and most of the structures that need to be vapor sealed and insulated.
Hotwalls
When making a comprehensive assessment of your home’s efficiency, an element often overlooked are vertical walls in the attic. These walls are often only insulated by leaky batt insulation, and sometimes with nothing at all, leaving only sheetrock between the conditioned space and the attic.
This situation allows for ready heat transfer – heat from the attic into the home in summer, and heat from the conditioned space into the cold of the attic in winter. Installing three inches of open-cell polyurethane foam over the attic side of the hotwalls provides a complete air barrier and eliminating the heat-transfer problem.
Using thermal camera imaging, before and after images clearly demonstrate the impact of insulating the hotwalls. In the before images, the blue strip around the top of the ceiling clearly demonstrates where heat from the home was escaping. The after images show that the heat loss via the hotwalls has been eliminated and the room temperatures are now consistent.
BEFORE
The poorly insulated hotwall allows heat transfer around the top of the vaulted ceiling in the living room of this home
AFTER
The polyurethane foam-insulated hotwalls now prevent heat transfer.
