Should I use R19 or R21?
Both come in rolls and are installed the same way. R-21 insulation is more efficient at preventing the transfer of heat, but it costs more per square foot. Construction companies often use R-19 as the standard insulation and may offer R-21 insulation as an available upgrade to buyers.Will a R21 wall fit a 2x6?
Insulation for 2x6 WallsUse R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2x6) walls. This combination ensures that the insulation is neither too loose nor too tightly packed within the walls.
What is the R-value of 6 inches of spray foam?
Spray foam comes in two types, mainly open-cell and closed-cell. Open-cell spray foam has an R-value of around 3.5 per inch. The closed-cell, which is more effective, has a higher R-value ranging between 6 and 6.5 per inch.Which is better R13 or R19 insulation?
Although the U.S. Department of Energy rates R-13 insulation as "good" for use in walls in southern areas of the country, it rates R-19 insulation higher, designating it as "great." That is because R-19 insulation provides more thermal insulation than R-13 does.What is R19 insulation used for?
The Basics of R19 InsulationR19 Insulation is any type of insulation that achieves that specific R-Value measurement of R19. R-value is used to judge thermal insulation performance and the higher the number, the better the product's insulating ability. So R19 has better insulating ability than R13.
What are the 3 types of insulation?
Types of Insulation
- Fiberglass: Fiberglass is the most common insulation material. ...
- Cellulose: Cellulose insulation is made from recycled paper products. ...
- Foam: Foam insulation may be made from polystyrene, polyisocyanurate or polyurethane, which are all types of plastic.

What does R30 mean on insulation?
A wall is R-19, a roof is R-30 — what does this mean? Essentially R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less heat loss, the lower your energy bills.What is R-13 insulation used for?
What is R13 Batt Insulation? R13 batt insulation is typically used to attenuate sound in interior wall cavities. It is akin to a large blanket, designed specifically to fill a wall, floor, or ceiling cavity.What R-value do I need for exterior walls?
