Answer
A standard 3.625-inch thick brick does not even come close to reaching R-Air is a somewhat better insulator than masonry, but only by a small margin. An inch of calm air has an R-value of around 0.4The result is that an outside double brick wall with 2 inches of air between them and internal plaster will produce no more than R-3 of insulation.

R-value is a measure of how well something works (insulation)
A vacuum insulated panel has the greatest R-value, roughly R-45 (in U.S. units) per inch; aerogel has the second highest R-value (around R-10 to R-30 per inch); and then there are polyurethane (PUR) and phenolic foam insulations, all of which have R-7 per inch of thickness.
Straw bales have an R-1.5 per inch performance rating.
The majority of effective insulation does little more than trap air; this is why most insulations are light and fluffy in appearance. Brick isn’t exactly light and fluffy, but it’s also not heavy. As a result, it is not a very effective insulator. A brick veneer home, on the other hand, is basically a wood frame house in which the hollow between the studs in the wall may be insulated to provide additional insulation.
Vertical air gaps in walls often have the same heat flow inwards and outwards as horizontal air gaps in walls. High emittance surfaces offer little or no resistance to heat transfer, resulting in a low R-Value for the air gap between the surfaces. Surfaces with low emittance on one or both sides of an air gap result in air gaps with greater R-Values when compared to surfaces with high emittance.
Easily distinguished by its blue, green, or pink hue, XPS rigid-foam insulation is in the centre of the three varieties of rigid-foam insulation in terms of both cost and R-value, and it is the least expensive (about R-5 per inch). XPS is available unfaced or with a variety of plastic facings to choose from. It has a perm value of roughly 1, which indicates that it is semipermeable when it is not faced.
You’ll need a varied R-Value depending on where you reside and whatever area of your house you’re insulating (walls, crawlspace, attic, etc.). R-13 to R-23 are typical recommendations for exterior walls, whereas R-30, R-38, and R-49 are typical recommendations for ceilings and attic spaces. R-13 to R-23 are typical recommendations for external walls.
R-Values for Composite Walls In most cases, walls are constructed of numerous layers of various types of materials. In order to compute the R-value of a composite wall, the effective R-values of each of the wall’s layers must be added together.
Double brick is a term that refers to two brick walls that are separated by a hollow, which lowers heat transmission and prevents moisture from being carried straight from the outer walls to the inside of the home’s structure. It serves as an excellent insulator, keeping your house cooler in the summer and warmer in the winter. Noise-cancelling properties. Termites and rot are less of a threat.

Tyvek® ThermaWrap® R0 provides the same breathability and water management advantages as DuPontTM Tyvek®, as well as an extra 1 12 inches of length and width “Insulated batting with an R-value of 5.0 is used in this application.
However, because of the minor reduction in emissivity, the overall R-value has been reduced to R-8.1Assume that the product in question is an aluminium foil that has been exposed to water. According to the American Society of Heating, Refrigeration, and Air Conditioning, when just a little amount of condensation is visible on aluminium foil, the emissivity may approach 0.2 to 0.3, lowering the R-value to R-3.86.
The R-value of blown-in fibreglass ranges from 2.2 to 2.7 per inch. Batts. Fiberglass batts and rolls are perfect for use in the building of floors, walls, attics, and ceilings, where they may be sandwiched between frame members. They have a higher density than blown-in insulation and may provide an R-value of up to 4.3 per inch of thickness.
With the addition of insulation, brick dwellings are able to sustain lower temperatures than structures constructed of lighter-weight construction materials. When winter arrives, the inside of a brick wall actively absorbs and redistributes heat back into your home, assisting you in keeping it warmer for longer periods of time.
Winter may be a very expensive time for any homeowner, but owners of brick houses should reasonably expect to spend less money on heating expenditures than owners of other types of homes since brick is more energy efficient than other construction materials. Thermal mass is defined as the capacity of a heavy, dense substance to retain heat and then slowly release it back into the surrounding environment.
For comparable-sized houses, the study in the whitepaper mentioned above demonstrates that the brick home has an instant rise in value of around $4,000 when compared to the wood or fiber-cement siding counterpart.”
Furthermore, studies have shown that brick houses sell more quickly than comparable-sized homes with less durable exterior (such as vinyl siding).
Using bricks in construction has a number of pros and disadvantages. It is cost effective. When compared to other construction materials, such as wood, they have cheaper maintenance expenses than other materials. Bricks have a longer life span when compared to wood since they are less subject to deterioration or destruction by insects like wood is.
In order to properly insulate a structural brick wall (e.g., multiple-wythe brick or brick veneer on block), you must insulate it from the inside. For this to work, stiff insulation board (either foam or mineral wool) will need to be applied to the interior of the wall, and then covered with drywall.
For the most part, wood is more handy than plastic, particularly in specific situations. Wood holds up better in locations where erosion and silt collect because erosion and silt harm brick walls, but wood is more resistant to erosion and silt. Wood is also a superb insulator, as previously stated. Another benefit of concrete over brick is that it is more adaptable.
