Attic/Ceiling Insulation

Properly Installed Insulation
Improves Comfort While Saving Energy

Attic Insulation Application

Insulation is one of the keys to a comfortable, energy-efficient home. But simply having the right amount of insulation is not enough. If insulation is not properly installed, a home can have excessive heat gain during the summer and heat loss in the winter — forcing the heating and cooling systems to work overtime.

Properly installed insulation will completely blanket the home — exterior walls, ceiling and floors — without gaps, voids or compressions. It will be in full contact with the interior air barrier (for example, drywall). Continuous sealing of the air barrier along the insulation is also critical to protecting against the moisture damage caused by warm air flow through the insulation to colder surfaces where it can condense. Expect ENERGY STAR-qualified homes to have insulation that meets or exceeds the latest national code requirements, providing year-round comfort while reducing utility bills.

Benefits of Properly Installed Insulation

  • Enhanced Comfort. Properly installed insulation minimizes temperature variability indoors and helps keep rooms warmer in the winter and cooler in the summer.
  • Lower Utility Bills. As much as half of the energy used in your home goes to heating and cooling. By preventing heat loss in the winter and heat gain in the summer, a properly installed insulation barrier reduces utility bills year-round.
  • Improved Durability. When insulation is properly installed, the potential for condensation that can lead to decay of building materials is reduced, helping to improve the durability of your home.
  • Better Resale Position. The improved comfort, lower utility bills and improved durability of a properly installed insulation barrier can translate into higher resale value than less efficient homes.

Types of Insulation

Builders have many choices for the types of insulation they use. All insulation can be effective if it is properly installed and coupled with a continuous air barrier. Insulation materials are rated according to their ability to resist heat flow. This thermal resistance rating is commonly known as an “R-value.” The higher the R-value, the better the material is resisting heat flow. ENERGY STAR-qualified homes can include one or more of the following types of insulation:

Batt Insulation is typically made from mineral fiber (fiberglass or rock wool) and manufactured in blankets of various sizes and thicknesses. Batt insulation is typically fitted between studs, joists, and beams and should fill the wall, floor or ceiling cavity without gaps, voids or compression.

Blown-in Insulation is typically made from fiberglass or cellulose and is literally blown into the walls and attic through a large hose. Blown-in insulation should fill the wall cavities and even thickness throughout the attic.

Sprayed or Injected Foam Products are typically made from polyurethane or similar products and are injected or sprayed into cavities where they expand to the desired thickness.

Rigid Insulation is typically made from polystyrene, polyurethane or polyisocyanurate foam, which is expanded or formed into large sheets. Rigid insulation can provide a continuous thermal barrier in basements, crawlspaces and exterior walls.

Program Guidelines

  • This rebate is available for new construction projects and home improvement or retrofit projects.
  • Rebate Amount = ($0.01) x (square foot of insulated space) x (R-Value added); up to $500.
  • Attic insulation must be installed between conditioned (air-conditioned living area below the ceiling) and unconditioned areas (attic) to qualify.
  • Garages and other non-living areas do not qualify.
  • Final insulation must have an R-value of at least R-38.
  • Polyurethane spray foam (closed-cell) shall be a minimum of 5 inches in thickness when applied to the interior roof deck.
  • Polyisocyanurate spray foam (open-cell) shall be a minimum of 5.5 inches in thickness when applied to the interior roof deck.
  • The current insulation level of each home will be determined and documented by the insulation installer; degradation due to age and density of the existing insulation should be taken into account.
  • BPUB will verify square footage measurements against Cameron County property tax records showing the home's floor plan.
  • An itemized and dated invoice from the contractor or retailer, including manufacturer, type, R-Value, number of bags installed, square footage, and application, is required.
  • Applications are subject to verification. If the application can't be verified, the rebate will not be paid.
  • The address of the account must match the address of installation.
  • Applications must be completed and submitted within 30 days of installation. Please allow 3-6 weeks after receipt of all documentation for the rebate to be issued.
  • The rebate recipient must be a customer of BPUB electric services.
  • Call (956) 983-6282 or email to verify that your application was received.

A Better Future

ENERGY STAR is a voluntary partnership between the government and more than 9,000 organizations, including more than 3,500 of the nation's homebuilders. Together with home buyers and their families, we are working to achieve a common goal — protecting the environment for future generations by changing to more energy-efficient practices and products today.

ENERGY STAR is the government-backed symbol for energy efficiency. It identifies new homes, buildings and more than 50 types of products that are energy efficient and offer the features, quality and performance that today's consumers expect. Products that can earn the ENERGY STAR include windows, heating and cooling equipment, lighting, and appliances. To learn more about ENERGY STAR, visit
