Insulation Services in Thibodaux, LA

While improvements in technology have resulted in remarkable gains in HVAC efficiency, it is important to recognize that insulation consistently offers the highest return on investment. A properly insulated home or business is your first step toward energy efficiency that impacts the bottom line. The experts at Doug’s Air Conditioning can perform a complete energy analysis of your home or office and provide comprehensive Heating, Cooling, Indoor Air Quality, Plumbing and Electrical services.

Insulation

Polyurethane Foam

Polyurethane foam is a dual component insulation and air sealant material. Originally developed in the 1930s for military applications, spray foam insulation has several unique properties that make it the perfect insulation choice for energy-conscious consumers. Most notably, expanding foam completely fills the contours of irregular gaps and crevices to effectively seal a building’s perimeter.

Rigid polyurethane insulation is distinguished by its two-part mixing process. Low-pressure foam is designed for small consumer applications such as weatherization and insulation repairs. High-pressure foam is contractor applied, and it is commonly used to insulate underground piping, heating vessels, and total building envelopes.

Commercial-grade spray foam insulation is made by combining two isolated chemical ingredients. At the application site, the two chemicals are pushed through separate hoses and combined in a specially designed mixing chamber. The equipment also adds heat, propellants, and air to the resulting reaction.

The two main components of spray-in-place foam material

  • Part A: Isocyanate or Isocyanine derivatives give the material its unique insulating properties.

  • Part B: Polyol Blend or Poly-based resin stabilizes the A-side chemical to ensure that the reaction is controlled.

The Difference between Open Cell and Closed Cell Polyurethane Spray Foam Insulation

  • Closed-Cell Foam: Closed-cell polyurethane foam is extremely durable and energy efficient. The structure incorporates a portion of the blowing agent directly into the cells, which improves the overall efficiency of the material. Since the cells are closed, moisture cannot be transferred through them. Normally applied at a density of 2.0 pounds per cubic foot, closed-cell foam yields an exceptional insulating value of R-6 per inch. Closed-cell foam is also extremely effective in low-frequency noise control and can add to the structural integrity of the building.

  • Open-Cell Foam: Open-cell foam is a light-density material that appeals to cost-conscious consumers. While per inch R-values are typically half of those provided by its closed-cell counterpart, open-cell architecture offers superior noise control across all frequencies as well as a lower installed cost. Open-cell foam should not be directly exposed to the elements and usually requires a moisture barrier to eliminate the potential for mildew growth.

The Benefits of Polyurethane Foam Insulation

Rigid polyurethane foam insulation has numerous benefits. Perhaps most importantly, foam fills gaps, crevices and irregular shapes while it expands in wet form. The capacity for expansion effectively seals the building perimeter against unwanted air infiltration, pollen, dust and pests. Controlling leaks in the building envelope can help eliminate drafts, which will improve indoor comfort and lower associated energy bills.

Enhanced R-values can also help reduce heating and cooling capacity requirements, which may result in lower equipment costs. Reduced system runtime can lessen maintenance and repair expenses while extending the equipment lifecycle.

As a “green” material, closed-cell foam is impervious to moisture, which can eliminate the conditions required to sustain mildew, fungi and other undesirable biological agents. The high density of cured material helps reduce unwanted outdoor noise, and the rigid composition of foam provides homeowner’s with a feeling of safety and security.

Fiberglass Insulation

As a standalone system, fiberglass is the industry standard for insulating residential and commercial buildings. Available in a variety of sizes and thicknesses, fiberglass is manufactured in pre-cut pieces or as a loose-fill material. When installed as a wet spray, fiberglass can be used in wall cavities to substantially reduce air infiltration.

Since fiberglass insulation has open-cell composition, it is an effective barrier against conductive and convective heat flow. By limiting the movement of air within its woven structure, energy transfer is restricted, which can result in a reduced furnace and A/C equipment load. In fact, upgrading existing insulation to meet current Department of Energy published standards can lower heating and cooling costs by as much as 30 percent.
