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.
However, Insulation helps you to control the temperature of your home. From our earlier discussion, we already know that a higher R-value works more efficiently. Therefore, if you're looking for energy-efficient insulation for your home, then we recommend you buying R15 over R13.
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.
Depending on where you live and the part of your home you're insulating (walls, crawlspace, attic, etc.), you'll need a different R-Value. Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces.
They are available in widths suited to standard spacings of wall studs and attic or floor joists: 2x4 walls can hold R-13 or R-15 batts, 2x6 walls can have R-19 or R-21 products.
Uses of R-19 In many regions of the country, R-19 insulation is recommended for use in outer walls of new construction projects. A different type of insulation is used in areas like basements and attics, and to insulate floors.
Exterior Garage Walls Typically these will be constructed from standard 2-by-4 studs which will define the amount of insulation that you can have installed. You should be targeting an R-Value of R-13 or R-15 in these areas to properly maximize your insulation in this application.
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy's (DOE) ranges for recommended levels of insulation below.
This Johns Manville insulation was created for walls and attics to improve energy and acoustic efficiency. You will appreciate the flexible material made of fibreglass without formaldehyde and resistant to fire and mildew.

"R" means resistance to heat flow. Here's what to know: The higher the R-value, the greater the insulating power. Almost all insulation products have to tell you their R-value — including duct wrap.
If you are adding R19 to current insulation then yes, you can add the batts of insulation cross ways over the existing layer and above the joists or bottom of the trusses. Hot air rises and beefing up your attic insulation is one of the best things you can do to keep the heat in.
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. Newer, smarter standards are 2x6 walls (a larger cavity provides more room for a thicker thermal barrier) with R-19 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.
R13 fiberglass batt insulation, typically used in walls and floors, is 3 5/8 inches thick, according to Energy.gov. Insulation needs and the effectiveness of the insulation vary depending on climate and material. Rigid foam board is prized for its high R-value in a panel that's much thinner than fiberglass batts.
Use R-40 thick insulation for the ceiling.
The effectiveness of the insulation is expressed as an R-value*, which is a measure of thermal resistance to heat flow. The higher the R-value, the better the insulation in the door. Classic Steel Model 8500 has the highest level of garage door insulation for our residential doors with an R-value* of 16.22.
R-value measures how well building insulation can prevent the flow of heat into and out of the home. Higher R-value means greater insulation performance, and thus more savings on your next heating and cooling bill.
TBF closed cell foam insulation and concrete board basement wall products offer industry-leading R-13 insulation value that will reflect back 99.987% of heat back and lead to the optimal insulating of a basement area.
Micro is smaller usually. However these terms are used a lot these days and in various contexts. So it is important to understand the context also. If you refer USB or HDMI cables or connectors then yes micro is smaller than mini.
How big of a boat to cross the Pacific? You need a boat that is at least 30 ft long to cross the Pacific, but it is much wiser to choose one that is at least 40 ft long. You need a boat this big because it needs to be seaworthy, have sufficient storage, and provide enough comfort for your journey.
Micro: A small scale ecosystem such as a pond, puddle, tree trunk, under a rock etc. Messo: A medium scale ecosystem such as a forest or a large lake.
