Different Types of Homeowner Insulation

Insulation

Inadequate insulation is vital to the amount of energy saved and of course, energy saved is money in your pocket! Heating and cooling account for 50 to 70% of the energy used in the average American home. Much depends on your roofs building materials. but there are many different types of factoring.

Before selecting insulation. you need to make sure that the material is appropriate for its intended location. It will need to be somewhat easy to install, affordable and perform well.

Proper insulation will save you money

The amount of energy you conserve will depend on several factors:

  • The local climate
  • Size, shape and construction of your home
  • Living habits of your home
  • The efficiency of your heating and cooling systems along with the type of fuel you use

The higher a materials R-value is, the better it is at resisting heat flow. Insulation with a high R-value is preferred more than insulation with a low R-value and insulation that resists airflow is preferable to air-permeable insulation.

Bats, blankets, loose fill and low-density foams all work by limiting air movement. (These products are known as fiberglass, cellulose, polyicynene and expanded polystyrene.) The still air is ans effective insulator because it eliminates convection and has low conduction.

Some foams such as: poly-isocyanurate, polyurethane and extruded polystyrene, are filled with special gases that provide addition resistance to heat flow. To reduce costs, many builders and general contractors choose air-permeable products with a low R-value. This is deemed as acceptable as long as air leakage is minimized by installing an air tight barrier and the thickness is adequate.

Types of Insulation

 A flexible blanket-like product made from fiberglass

They are available in widths suited to standard spacing of wall studs and attic or floor joists. They must be hand-cut and trimmed to fit wherever the joist spacing is non-standard such as: Corners, windows and doors. Even where there are obstructions in the walls like: Wires, electrical outlet boxes and plumbing.

Batts can be installed by homeowners or professionals. They are available with or without vapor-retarder facings. They have a special flame resistant facing and are available in various widths for basement wall where the insulation will be left exposed.

  • Fiberglass batts have R-values ranging from R-3.2 to R-3.8 per in.
  • Denser batts have higher R-values which increase energy savings
  • Low-density batts have only the virtue of low cost

At Wolf Restoration. we only use formaldehyde-free spun fiberglass batts, due to our concern for customer’s and installer’s safety.

Loose filled insulation consisting of cellulose or fiberglass material

This type of insulation can be used in wall cavities. It is also appropriate for unfinished attic floors, for irregular shaped areas and around obstructions. Typically blown-in products fill all the nooks and crannies of the areas they are installed and performance is much better than batt insulation.

Blown-in Fiberglass

Fiberglass insulation is typically installed on an attic floor and has a lower R-value per inch (R-2.2 to R-2.7) than any other common insulation product. Its best applied in attic that have enough room at the eaves to accommodate a very deep layer as much as sixteen to twenty-six inches.

Blown-in Cellulose

Cellulose insulation consists primarily of ground up newspapers. The shredded paper is mixed with one of several retarders, most commonly borate. The insulating value of cellulose is comparable to that of fiberglass. However, because cellulose is more resistant to airflow than fiberglass, it performs better.

In a closed cavity, cellulose should be installed by the dense pack method to a density of at least three pounds per cubic feet.

Polyurethane foam can be produced in two forms: Open and closed cell

Open Celled foam allows water vapor to move through the material more easily than closed cell foam. Open celled foams usually have a lower R-value for a given thickness compared to closed cell foams. Closed cell foams are able to provide a greater R-value where space is limited.

Polyurethane foam insulation can be applied by Wolf Restoration using special equipment. The equipment will meter, mix and spray the foam into the nooks and crannies of unusually shaped building cavities or the top of ceilings and attic walls.

Open Cell Spray Foam

R-Value: R-3.5 to R-3.6 per inch

Insulated residential home

Open-cell foams use water or carbon dioxide as the blowing agent. Some open-cell foams are made in part from bio-based raw materials. For example: Soybean oils, in place of a portion of the petrochemicals. Open-cell foam is usually more suitable for residential applications for a few reasons:

Closed cell spray foam insulation

R-value: R-6.5 per inch

Closed cell insulation is the most expensive residential insulation

When installed properly, it performs better than any other insulation. It is an excellent air barrier and is impervious to moisture, thus is serves as an effective vapor retarder. Because of its density and glue like properties, it adds structural strength to a wall, ceiling or roof assembly.

  • Provides incredible thermal performance and can be installed in areas that would be inaccessible or difficult for other forms of insulation.
  • Provides incredible thermal performance and can be installed in areas that would be inaccessible or difficult for other forms of insulation.
  • Effectively isolates air currents and moisture, reducing the chance of mold or mildew ultimately increasing the life of a home.

Many green builders avoid the use of closed cell spray foam because the blowing agents in most types of closed cell spray polyurethane foam are hydrofluorocarbons (HFCs) with a high global-warming potential.

Foam Insulation Sheeting

Foam board sheeting insulation can be the best type of insulation for many projects due to its high R-value (resistance against heat flow) and moderate costs. It is very efficient at stopping air leaks and can work as a moisture barrier. Foam board insulation can be used in outside/inside walls under floors, roofs, attics and on foundations. The two main types of foam board are listed below:

Molded Expanded Polystyrene Sheeting (MEPS) commonly known as beadboard, is a closed-cell matterial that can be molded into sheets of various sizes and densities, a standard 4 x 8 sheet can vary in thickness from 1/2 up to 2. R-values range from 3.8 to 4.4 per inch (2.54 cm) of thickness. Usually, this type of insulation is used in areas where space is limited but it also acts as a material for many residential applications at relativity low cost.

Rigid Foam Board (RFB). Polyiscoyanurate and Polyurethae foam boards are very similar, both are also a closed-cell insulaton material. However, they offer higher level of compression and strength compared to MEPS. Both materials offer high R-values (R 5.6 to R8) per inch of thickness. RFB with metal or plastic face can be used in applications were a moisture barrier is desired. Additionally, metalized RFB it can be used to created radiant heat barrier, making it an excellent choice for roofing and attic applications.
