Insulate for Savings

Home Insulation Facts

Without proper insulation energy can escape your home and add to monthly costs.


Without proper insulation, energy can escape your home and add to monthly costs. Increased, or newer insulation, is one of the most affordable ways to reduce energy costs year-round.

During the winter, heat escapes a poorly insulated home, requiring more fuel to keep warm. And during the summer, heat from the outside transfers through the walls and roof, making it difficult to keep your home cool.

Benefits of Insulation:

With proper home insulation, you can:

  • Ensure even indoor temperatures
  • Prevent icicle formations and ice dams in the winter
  • Reduce environmental impact
  • Save on heating and cooling costs

BantamWesson offers the following types of home insulation:

  • Blown-in insulation: Cellulose insulation that is blown or sprayed. It can conform to any space and is used for cavities, attics, floors and difficult to insulate spaces.
  •  Fiberglass batting: Batts are the most common type of insulation. It comes in pre-cut rolls that can be hand cut and is used for wall studs, attic trusses, rafters or floor joints.
  •  Ridged foam board insulation: Ridged panels that more dense than regular foam board insulation. Foam boards offer good thermal resistance and can be used in just about any part of your home where insulation is needed. 

What is an R-Value

An R-value is a measurement of the resistance of heat flow through the insulation. It measures the ability of heat to transfer from one side of an object to another. The higher the R-value, the better the insulation. 

Recommended R-Values for Connecticut

Connecticut weather can be extreme and unpredictable—below freezing temperatures and dangerous wind chills in the winter to extended heat waves in the summer. It’s important to ensure you use the correct R-Value for insulation suited for Connecticut weather.

Recommended R Values for Connecticut

(Zone 5)

Type of Heat/Area Gas, Heat Pump or Fuel Oil Electric
Attic R38 to R60 R38 to R60
Cathedral Ceiling R30 to R38 R30 to R60
Cavity R13 to R15 R13 to R21
Insulation Sheating R2.5 to R6 R5 to R6
Floor R25 - R30 R25 - R30

Where Should I Insulate?

  • Attic
  • Duct Systems
  • Cathedral Ceilings
  • Exterior walls
  • Floors (with cold spaces below such as crawl spaces or unheated garages)
  • Ceilings (with cold spaces above such as attics)

How can I tell if I need insulation, or need to replace existing insulation?

Home insulation can degrade over time, making it less effective and costly. How does this happen?:

  • Rodent damage
  • Impact of home renovation
  • Compression (from storage containers in the attic for example)
  • Gaps in the attic floor that cause air to move through the insulation, making it dirty and lowering its R-Value
(An attic floor that has large gaps with no insulation, which creates drafts and contributes to higher home energy costs.)
(An example of how a home renovaton project can damage or lower the insulation value. In this case, the homeowner added a bathroom fan and recessed lights--taking up space where the insulation once occupied and making the insulation less effective.)

In addition, many homes have insufficient or incorrectly installed insulation, making it less effective.

Consider the following:

  • Basement  You should not be able to see the paper backing. If you can, it’s been improperly installed and may pose a fire hazard.
  • Walls – Homes built before 1970 mostly likely need new insulation. Even in newer homes, the insulation could be installed incorrectly or incomplete.
  • Attic – If you can see the beams on the attic floor, then there is not enough insulation. If there is insulation missing around lighting fixtures or other fixtures, then more insulation is needed. Attic hatches should also have insulation.​
(Home insulation that was installed incorrectly with the paper backing facing up. The paper backing, in most cases, should be facing down. This not only lowers the value of the insulation, but it is also a fire hazard.)
(Attic beams showing insulation that has gaps and is damaged and dirty, which lowers the value of the insulation and makes it less efficient. In this case, the damage was caused by rodents.)
