M & M Insulation

Spray Foam

Spray Foam insulation is created by applying liquid foam that expands to fill the cavities in a house or building.

Spray Foam insulation has a much higher R-value (R7 per inch of foam thickness) than traditional fiberglass insulation. Properly installed, spray foam insulation has twice the insulating properties of fiberglass. As spray foam is applied, it expands to create an airtight seal adding to the energy saving nature of this insulation.

Spray Foam insulation increases the structural integrity of a home. By design, spray foam insulation is highly adhesive. The result is that the structural elements of a home are glued together. This “belt and suspenders” approach makes a house stronger in the face of the high winds delivered by a tornado or other strong storm.

Spray Foam insulation is perfect for insulating small or hard to reach areas such as rim joists. It does not shrink or settle, but expands naturally to fill gaps leaving no cracks. The millions of tiny air bubbles in the closed cell foam create an insulating barrier that helps reduce heating and cooling costs.

Spray Foam has a built-in vapor barrier so there is no need to apply a sheet of poly once the insulation is installed. It prevents the build-up of moisture, lowering the incidence of mildew and mold problems, and makes it more difficult for insects and other pests to burrow into a building.


Fiberglass insulation is a material made from sand and extremely fine fibers of glass.

Easy installation
Fiberglass insulation is easy to install since it sandwiched between two layers of batting, and cuts very easily. Fitting Fiberglass into odd shaped areas is not a problem, so it’s is a great choice for hard to reach places and attics. It is also great as a noise barrier.

Fiberglass insulation must be covered with a vapor barrier as seen in the photos above. A vapor barrier is a sheet of poly that is taped at the seams to ensure a tight seal.

Fire and moisture safe
Because Fiberglass insulation is made out of inorganic materials, it is naturally fire retardant which makes it a solid choice around electrical wires. Fiberglass insulation does not hold water and will quickly dry if it becomes damp or wet. Fiberglass tends to be less dusty and is already dry material.

Made to last
The R-value of Fiberglass insulation remains constant no matter how long it’s been installed. It cannot settle or become compacted, since the individual fibers are held in place by the outside batting.

Net-In Blow

Net-In Blow (also known as Blown Fiberglass) is an insulation process that blows loose-fill fiberglass insulation into building cavities. Blown Fiberglass gives a home a seamless, thermally efficient, sound reducing blanket that completely fills any cavity, leaving no voids.

Blown Fiberglass can be used for attics, sidewalls, cathedral ceilings, floors, and any closed-cavity area. It has an R-value of R23 in a 2 x 6 wall.

Cleaner product
Blown Fiberglass insulation uses clean products so there are fewer allergy concerns. There is no adhesive required, no fallout, and less dust and fiber fly.

Tighter fits
Since Blown Fiberglass insulation can fit into even the tiniest existing cracks, you get a much tighter fit. This means a better result with fewer air leaks and a great sound barrier. A vapor barrier must be used with Blown Fiberglass insulation.

No settling Net-In Blow insulation is made of fiberglass and can be blown in and compacted at a high density which helps keep the insulation from settling.

Hybrid Systems

A Hybrid Insulation System combines both spray foam and fiberglass insulation techniques. Typically, in a standard 2x6 wall, one-inch of closed cell foam is sprayed inside the wall cavity, and the rest is filled with either fiberglass batts or blown fiberglass.

The idea behind using a Hybrid Insulation System is to get all the air sealing benefit from the spray foam, as well as the reminder of the R-value from the less expensive fiberglass.

The Hybrid Insulation System is very effective when used in walls, crawl floors and attics and provides a very high R-value application (1” of spray foam insulation provides R7, and combined with an R19 fiberglass batt = R26).

Fiberglass insulation provides uniform application, and can be blown in as thick or as thin as you choose, building to the R-value that you choose.

Attics with existing insulation can be reblown or touched up to increase the R-value.
