There are many materials and techniques for insulating your home. Different types of insulation have unique properties making them suitable for specific applications, all of which must be taken into consideration for each project. The R-value, or Resistance Value, measures the rate by which heat moves through an insulation material. Higher R-value results in lower heat transfer and higher insulation performance. Our team will advise you in selecting insulation materials that optimize acoustic performance and sound proofing, fire resistance, and effectiveness as moisture/vapor barriers. The chemical composition of each material also confers physical characteristics like weight, texture, porousness, flexibility, and safety that determine how they can be applied in different situations.

Cellulose Insulation

Short Version
Long Version

Cellulose insulation involves blowing fiberized newsprint into areas of a house at high pressure. It was invented by the military in the 1940s and gained prominence for residential use in the 1950s. The installation techniques, composition and manufacturing of cellulose insulation have been perfected over the decades to make it among the most efficient, greenest, safest and most cost-effective forms of insulation on the market. Home Comfort Practice installs cellulose insulation blown in cellulose in attics and exterior walls because it is clean, green, and effective. What type of insulating material would you use to surround your family? (Volatile petrochemicals?)

Installing Cellulose Insulation

Loose-fill Installation

Loose-fill installation blows the cellulose material onto the attic floor until a 10" to 18" blanket is established. For dense-pack installation, 3" circular holes are drilled into walls or floors, a tube is installed into the cavity, fiber material is blown into the enclosed cavity until it is filled, and holes are sealed and restored. Loose-fill installation achieves a high R-value (resistance to heat flow) of R-3.8 per inch. Dense-pack installation achieves approximately R-3.6 per inch.

Loose-Fill Insulation Dense-Pack Insulation

Dense-pack insulation

Dense-pack cellulose insulates and air seals, and it maintains its R-13 thermal resistance value by blocking air flow through the wall cavity. When fiberglass insulation has been used, the fluffy, cotton-like material permits air to flow through the cavity and degrade the fiberglass' R-value.

Spray Foam Insulation

Intro to Spray Foam Insulation
Spray Foam Insulation FAQ

Spray foam insulation has the ability to create airtight envelope within the building structure, providing effective air sealing. This also prevents convective heat transfer from interior to exterior during as the heat is prevented from escaping through gaps in the buildings envelope. Medium-density closed-cell and light-density open-cell are the two main types of spray-in insulation foams. With closed-cell foam insulation cells are closed and filled with a low-conductivity gas, whereas open-cell foam cells are open, lower density and filled with carbon dioxide. The former has medium/high-density and the latter has a sponge-like appearance and texture. They both expand into the shape of the cavity within which they're applied, filling and sealing them. Open-cell spray foam absorbs and holds water and is vapor-permeable and is unsuitable for areas with moisture while closed-cell spray foam has a far better R-value, is air-sealing and much less permeable.

During installation, a two-component mixture comes together at the tip of a nozzle, forming an expanding foam that is sprayed into wall cavities, or blown into holes drilled into a cavity of a finished wall. Foam insulation can also be sprayed onto roof tiles, concrete slabs and under floors. The toxicity of the volatile compounds dissipates as the mixture hardens and cures. Slow-curing liquid foams are also available and designed to flow over obstructions before expanding and curing, and they are often used for empty wall cavities in existing buildings.

The cost of spray foam insulation varies based on the type, composition and installation methods required, but they're usually all more costly than other forms of insulation. For example; closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive to install. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water.

Blanket insulation: batt insulation and roll insulation.

Short Version
Long Version

Roll and batten insulation are among the most readily available forms of insulation products. They come in batts or rolls made up of insulating fibers, the most common of which is fiberglass insulation.They're also available mineral wool (also known as rockwool insulation) and various other natural or synthetic materials. The sizes are standardized to the most common stud and joist spacing specification but can be manually cut or trimmed to fit custom spaces. Common features also include outer insulation facings composed of different foil or paper materials. These insulation facings act as air and vapor barriers, in addition they may also confer special flame-resistant properties.

Foam board insulation and rigid foam insulation

Intro to Form Board Insulation
Foam Board Insulation FAQ

Foam boards are rigid molded panels of insulation. They work by trapping air or another gas in a petroleum-derived polymer (commonly polystyrene, polyisocyanurate known as polyiso, or polyurethane), providing air flow resistance and high thermal resistance. A thin sheet of foam insulation can be up to twice as insulating than most other materials at the same thickness. Foam board insulation is very versatile and can be used in a variety of locations throughout the home. Rigid foam boards are great for basement applications, crawlspaces and special applications such as attic hatches. Though highly effective, certain chemistries can suffer from thermal drift or ageing which is a decrease in the R-value over time as some of the low-conductivity gas escapes.

In comparison to fiberglass insulation, dense-packed cellulose insulated walls maintain considerably lower moisture levels even without an added interior vapor barrier.
  12. Is cellulose insulation fire-resistant?

    Yes, cellulose insulation is fire-resistant. Its dense fiber structure and fire retardants slow down the spread of fire, providing occupants with more time to escape and firefighters more time to save the structure. Cellulose insulation produces negligible smoke when exposed to fire, reducing the risk of loss of life in a structural fire.
  13. How does cellulose insulation contribute to soundproofing?

    Cellulose insulation has a high Sound Transmission Class (STC) rating of between 44 and 68, depending on thickness and density. It also has a Noise Reduction Coefficient (NRC) of between 0.90 and 1.00. These ratings demonstrate its ability to absorb and reduce sound, making it an excellent choice for soundproofing your home.
  14. What is the recommended insulation for the attic floor?

    According to EPA Energy Star, at least R-49, approximately 14" of loose-fill cellulose insulation, is recommended for the attic floor in homes in Connecticut. Increasing attic insulation levels beyond R-49 further enhances the thermal barrier between your living space and the attic.
  15. How does loose-fill cellulose insulation work for attic floors?

    Loose-fill cellulose insulation is blown onto the attic floor until a blanket of 10" to 18" is established. This high R-value insulation helps prevent heat loss and wasted energy by minimizing heated air escaping into the attic. Proper air sealing of penetrations and installing sealed covers over fans and other openings further enhances insulation effectiveness.
  16. What is dense-pack insulation, and where is it used?

    Dense-pack cellulose insulation is used in exterior walls to insulate and air seal. It is typically used in walls constructed with 2" x 4" studs and fills the space between the exterior sheathing and interior sheetrock. Dense-pack cellulose maintains its thermal resistance value (R-13) by blocking air flow through the wall cavity, unlike fiberglass insulation, which allows air to flow through and degrade its R-value.
  17. What is spray foam insulation, and how does it work?

    Spray foam insulation creates an airtight envelope within the building structure, effectively sealing against convective heat transfer and preventing heat from escaping through gaps in the building envelope. It comes in two main types: closed-cell foam and open-cell foam, each with different properties and applications. Closed-cell foam provides stronger resistance against moisture and air leakage, while open-cell foam is lighter and less expensive.
  18. How is spray foam insulation installed?

    During installation, a two-component mixture is sprayed into wall cavities or blown into holes drilled into a finished wall.
