The R-value is a measure of the resistance of an inch. This determines how durable your insulation can resist heat flow. Based on the type of insulation, R3.8 is the recommended R-value for most attics.


In terms of insulation, what is the recommended amount?


It is important to keep these in mind. will help you determine how much insulation your attic needs:


  • You might require more insulation, based on the climate in your region to ensure that your home is secure.

  • If you're living in an older home You'll require additional insulation to maintain the temperature.

  • Your attic's volume: Your attic's size impacts how much insulation you'll need. If you require expert advice get in touch with a professional.

Insulation Material Types


Insulating your attic can be accomplished using a variety of materials. Before you buy attic insulation, it's essential to be aware of the different materials that are available.


  • R-values can range between 3.8 to 5 per inch for polystyrene. This material is most commonly used in foam board insulation.

  • R-values can range between 3.5 to 6.5 per inch for liquid polyurethane insulation. The use of open-cell insulation or closed-cell insulation may affect the R-value.

  • Cellulose, the primary ingredient that makes up the majority of it, is made from straw, cardboard newspaper, straw, and other substances. It is an insulating material and has been in use for several years. Its R-value is 3.8 per inch.

  • It's easy to cut fiberglass insulation since it's made of light, woven fibers. It has an R-value of 2.7 Which is the standard.

  • DENIM The cotton used in the production of denim is used to create it. It's safe and easy to install, however, it's also more costly than the other alternatives on the market today. An R-value of 3 is the best for restricting airflow.

  • Rock wool and slag wool are two examples of mineral wool. Slag is created from molten metal waste products. It has a 3.3 R-value. It's fireproof.


When is Attic Insulation Not Needed?


Attic insulation in older houses must be handled with care. In between the walls of older homes, there was a lot of space for expansion. It is possible for mold to grow in these spaces if they are insulated, preventing the moisture from drying and causing damage.

  • Insulation foam boards


Depending on the thickness, foam boards could be rated with an R-value ranging from 6.5 to 6.5. Polyurethane, polystyrene, and polyisocyanurate are the main ingredients used to make them. Compared to other materials of the same thickness, their resistance to heat is twice more effective.


A foam board is ideal in humid environments because it doesn't store moisture.


  • Spray foam is a great insulation option.


It is sprayed into the walls and attic walls with the liquid polyurethane which sets when it gets cooler. It's versatile and can be utilized in smaller areas. It's the most expensive method of limiting the transfer of heat and cold. Spray foam is more complicated than it seems, so if you've never used it before, you might consider hiring a professional.


There are two kinds of spray foam insulation:


  • Closed-cell cells: The cells comprised of this kind contain gas, which assists in the expansion of the foam and fills the surrounding gaps. It has the highest R-value at 6.2/inches.

  • This kind of cell is spongy due to the fact that it is packed with air. The R-value for this particular cell is 3.7.

  • Spray foam insulation containing formaldehyde as well as urea should be avoided for your safety.
