You can use foam board in the attic. It is an excellent installation option for the attic because it is lightweight, easy to work with, and offers high R-values. Often the R-value of fiberglass insulation is too low and requires the rafters to be retrofitted, making foam board a better choice.
Can I use Styrofoam for roof insulation?
EPS and STYROFOAM Brand Foam have excellent R-values making it perfect insulation for interior and exterior walls, roofing, and under slab & subfloors.
What is the best insulation to use in your attic?
Loose-fill fiberglass attic insulation still experiences convection, but not nearly as much as old fiberglass used to. If you check with the North American Insulation Manufacturers Association, they’ll assure you that fiberglass or mineral wool is definitely your best choice for attic insulation.
Is Styrofoam insulation better than regular insulation?
When it comes to which is best in the spray foam insulation vs. fiberglass debate, spray foam wins, hands down. If you’re a DIY-er, you may be used to installing fiberglass insulation. But if you’re looking for something that will last a lifetime, let a professional install spray foam.
What Styrofoam is best for insulation?
polyisocyanurate foam
Polyisocyanurate: Known as polyiso for short, polyisocyanurate foam has the highest R-value per inch (R-6.5 to R-6.8) of any rigid insulation.
How can I insulate my attic cheaply?
Quote from Youtube video: Just take an unphased insulation a roll it right on top and that one step there make it home much more energy-efficient.
Does Styrofoam insulate cold?
A closed container of Styrofoam creates a “cold zone” into which heat from the outside enters at a very slow rate. Styrofoam has good insulating properties because it has millions of tiny air bubbles that slow the progress of heat through the material.
Can you have too much insulation in your attic?
It’s possible to over-insulate an attic as too much will cause moisture buildup and eventually result in mold. Eventually, adding more insulation leads to diminishing returns in trapping heat as well.
Can I use rigid foam insulation in attic?
When used as attic roof insulation, rigid foam can be installed between attic rafters, directly beneath attic rafters, or in both locations. Like spray foam, rigid foam provides an air and moisture barrier as well as high R-value insulation.
How thick should attic insulation be?
about 10 to 14 inches
The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.
How thick should Styrofoam insulation be?
Most panels range between 3/8″ and 2.5″ in thickness, though other dimensions and thicknesses are usually available through custom order.
What is the R-value of 2 inch Styrofoam?
With an R-value of 13.1 for a 2″ thick sheet only two 2″ sheets are required to achieve R-25. 2. Extruded polystyrene or XPS (foam is usually pink or blue) XPS has an R-value of 5 per inch of thickness requiring 5″ of insulation to achieve R-25.
Is Styrofoam a vapor barrier?
Rigid foam board, especially foil-faced polyisocyanurate, creates a vapor-impermeable barrier, so the wall would have limited drying potential. Even more permeable types of insulation, such as expanded polystyrene, are vapor barriers when the installation is thick enough.
What is the cheapest insulation material?
fiberglass
The most common form of home insulation is the “batt and roll” or “blanket” type, which is the least expensive to purchase and install. Its most common material is fiberglass, but if you’re looking for an alternative, check out these natural fiber options: Mineral wool.

What is the cheapest ceiling insulation?
Fiberglass batts are typically the cheapest insulation, but a loose corner or tear can diminish the insulation quality.
Should I spray foam my attic?
Insulating the attic rafters with spray foam creates a conditioned space where your attic is the same temperature as the rest of your home. This keeps the external weather and moisture outside of the attic space so you don’t have to worry about any moisture problems or air infiltration.
Should you insulate attic roof rafters?
Insulating between rafters will do no good, because the attic should be ventilated, and the rafter insulation would be between two unheated spaces. You can add insulation to the floor; the more the merrier. Just don’t put it in the eaves. Also, make sure the attic is well ventilated.
Can I use old clothes for insulation?
Perhaps that’s not as mad as it sounds: waste textiles – old clothes, curtains, carpets – are the latest materials to be developed into insulation to help save energy and lower utility bills.
Is packing styrofoam a good insulator?
Styrofoam is exceptionally lightweight, an excellent shock absorber and an effective insulator, making it one of the most common plastics used in the manufacture of packing and insulating materials. Styrofoam is also thermoplastic, meaning it changes from a liquid to a solid at a certain temperature.
Can you use carpet padding as insulation?
While the type and quality of the carpet itself may seem like the most important consideration when purchasing new carpeting for your home, the carpet pad has a significant influence on the qualities of your carpet. Carpet padding can add insulating qualities to your floor for heat and for sound.
