Polyurethane spray foam is made by mixing reactive chemicals – isocyanate and polymeric resins – to create a foam. The mixing and reacting materials expand very quickly – on contact – to create foam that insulates, air seals and provides a moisture barrier. Polyurethane spray insulation is known to resist heat transfer extremely well, and it offers a highly-effective solution in reducing unwanted air infiltration through cracks, seams and joints.

There are two primary types of polyurethane spray foams, known as open cell and closed cell. They differ in densities and other aspects that can be beneficial or detrimental in a given application. Closed cell is the denser and more common of the two types of polyurethane spray foam. Open-cell polyurethane spray foams are much less common because they were originally manufactured by only one company, and their R-values are much fewer than those of closed-cell sprays.

Closed-cell spray foam insulation is renowned for being a superior material for both residential and commercial projects. Its unique application allows it to improve energy-efficiency while also enclosing conditioned air inside the structure, thus, reducing the amount of money spent on wasted energy. It’s also virtually impervious to moisture, preventing the loss of R-value, as well as the growth of mold.

Because it will not shrink or settle, its high R-value (which can reach R-20 at 3 inches and R-41 at 6 inches) and acoustical performance lasts the life of a structure. Properly installed, closed-cell spray foam insulation can adhere to a wide variety of substrates including concrete, metal and wood. It’s compatible with many exterior wall types and can be sprayed onto the exterior sheathing in new construction projects or assimilated between stud cavities in retrofit situations. It is also used for roofs, continuous insulation, interior wall cavity fill, unvented attic applications and under floors.

Low-density, open-cell polyurethane spray foam can provide continuous insulation and an air-sealing barrier. The foam’s open-cell structure gives some flexibility to the hardened foam. It can be applied on walls, attics, to ducts, ceilings and crawl spaces. It is known as an air barrier, but permeable to vapor and moisture. It is often used to fill cavities in walls during construction. In addition, this foam can help absorb sound thanks to its soft texture and open-cell structure.

When you contact Mainline Home Energy Services for an insulation estimate, we will inspect insulation levels and determine the best insulation solution based on your home’s design and your specific needs. We have the experience and tools to install many different insulation materials, including spray foam, blown in, cellulose and more.

Spray foam is today’s most versatile material for home energy retrofit projects. It is also seen as one of the most expensive materials to be used for air sealing and insulating, but this needs to be weighed against the benefits it delivers.

First, there are two kinds of foam that can be used to insulate your home – open cell and closed cell. Both are polyurethane based and must have an ignition/thermal barrier applied, if applied in actively used spaces (such as a walk-in attic for example). The ignition/thermal barrier can be in the form of sheetrock, plywood or an intumescent paint that is applied over or sprayed directly onto the foam.

Open-cell spray foam is used to fill larger cavities where there is no requirement for a vapor barrier – think interior walls or cavities behind basement walls and the foundation for example. Sometimes known as ½ lb foam, it weighs about that much per cubic foot and has an R-value of about R3.7 per inch.

Closed-cell spray foam is a 2 lb foam, has an R-value of R6.5 per inch and is used in applications where an air and vapor barrier is needed along with the need to deliver high R in a small space – for example, it is the only material that can deliver R19 into a 2×4 construction wall (R19 is building code minimum for exterior walls).

Both products can be delivered in two formats – high pressure or low pressure.

High pressure applications require very heavy equipment in the form of trucks full of diesel motors, big compressors and generators. The chemicals atomize a significant amount into air on delivery, outgas during the curing process and require a 24-hour re-occupancy time – this means if you have this done in your home, you cannot be in the home during application nor can you enter your home for 24 hours after it is done.

Low pressure systems require much less equipment, atomize much less during application, and they do outgas during curing period, but only have a 2-hour re-occupancy time – you still cannot be in the home during application, but you may return within 2 hours once the job is complete.

Mainline uses a low-pressure, closed-cell spray foam exclusively for our projects as it delivers exactly the versatility we need to fix uncomfortable homes, convert 3-season to 4-season homes or for major renovation projects. It also delivers the highest quality air, vapor and insulation in a single product application, is less impactful on our customers’ schedules and is better for our environment.

Mainline recently upgraded its spray foam capability by retrofitting one of our trailers with a Nitrosys Spray Foam system developed by Spray Foam Systems, LLC of GA and co-partnered with our friends at Dr. Energy Saver.

Here’s a short list of projects that we can offer our customers using our low-pressure, closed-cell foam rig:

  1. Fix cold or humid room over crawl spaces – called encapsulation of the crawl space, we shut off air and vapor leakages and temperature stabilize the crawl space, which makes the rooms above more comfortable.
  2. Fix cold or humid basements – we encapsulate the sill and rim joist areas, which stops air and humidity infiltration.
  3. Insulate and seal off stone walled basements – in much older homes, lots of cold air and humidity seeps in through the stone wall foundation along with the sill and rim areas. We fill all crevices and cover the entire wall, then cover with intumescent paint for the ignition/thermal barrier. Problem fixed!
  4. Conversion of elevated patio rooms into 4-season rooms – we air seal and insulate under the floor and also install a ductless mini-split system to add high-efficiency heating and cooling.
  5. Upgrading older homes during reconstruction or major renovations – many of these homes have 2×4 construction walls, and we are able to get to code and seal off all air leakage points through the walls. We may also perform basement or attic work at the same time to make the entire home more comfortable and energy efficient.
  6. Making rooms over garages or entire attics into conditioned spaces – we basically use the foam to air seal and insulate roof lines and gable ends to required R-values per local building code and then add a ductless mini-split heating and cooling system. More of the home is now available as useful living space and much more energy efficient.
  7. Fixing leaky ducts in attics – homes with central air conditioning and heating systems use ductwork to move air through the home. If they are old and in the attic, then they create a very inefficiently and underperforming system. We encapsulate the trunk and branch lines, and this seals and insulates them. Heating and AC systems run less, and more of home is comfortable and energy efficient.

The common theme here is we make homes more comfortable and energy efficient and have the skills and equipment to deliver the best results available! Contact us today for your free home consultation and perhaps our new Nitrosys rig will be commissioned to get the job done for you.
