Open Cell Spray Foam

Open cell spray foam is a light-weight insulation material that is best suited for attics, rim joists, crawl spaces, or open wall cavities. It is made of two liquids – a polyisocyanurate (ISO) and a resin – that are kept separate until it’s time to use them. When applied, the foam instantly expands more than 100 times to fill every nook and cranny. A few other qualities of open cell spray foam include its sound dampening qualities, the air seal it creates, and that its blowing agent is water.

Closed Cell Spray Foam

Closed cell spray foam is a medium density, rigid polyurethane foam that provides an excellent air, vapor and moisture barrier. It is used in interior and exterior applications, both above and below grade. Closed-cell foam has a much higher R-value than traditional insulation and can maximize R-value with limited thickness. It is composed of many bubbles suspended in a polyurethane matrix that are filled with a blowing agent.

Insulation Removal or Suck Outs

Insulation removal or suck outs are processes used to remove old insulation material from a building. The process involves using a vacuum powered by a motor to suck up the insulation material. The insulation material is then stored and disposed of in accordance with local and state laws. The equipment and supplies needed for the project will be determined by the type of insulation to be removed.

Crawl Space Encapsulation

Crawl space encapsulation is the process of sealing off a crawl space from exterior elements using a heavy-duty polyethylene barrier. The barrier covers the floors, walls, and sometimes the ceiling of the crawl space. Encapsulation also involves sealing any vents and adding insulation where needed. Encapsulation can help keep the crawl space dry, clean, and comfortable.

Blown-In Fiberglass and Cellulose

Blown-in fiberglass and cellulose are two types of insulation that can be used in attics and walls. Blown-in fiberglass is made of very fine strands of glass. It has a low R-value (2 to 2.7) per inch, so it is best applied in attics that have enough room to accommodate insulation 16 in. to 26 in. deep. Blown-in cellulose is made of ground-up newspaper mixed with a borate-based fire retardant. Because it is denser than fiberglass, it is more effective at reducing air leakage. Loose-fill cellulose insulation is manufactured primarily from recycled newspapers, a very benign product, so it poses virtually no ongoing health risk.

Fiberglass Batts

Fiberglass batts are pre-cut pieces of insulation that are designed to fit in the space between the wall studs, ceiling or floor joists, or roof rafters of a building. They are made in different thicknesses and widths in order to fill these spaces completely, depending on the material that was used in construction – wood or metal frame. They are easy to install, durable, and create an airtight seal that prevents cold drafts from entering your home. You can cut, peel and staple them into place without special tools or skills. An unfaced fiberglass batt is one that has nothing added to any of its six sides. On the other hand, a faced fiberglass batt will have a material of either kraft paper, foil, or vinyl on one side. Depending on the material, it will provide a vapor barrier, a flame retardant surface or a light-reflecting face.
