The article discusses the process of insulatement for concrete-block walls, focusing on the insulation options available. It highlights that there is no effective way to fill voids in existing concrete-block walls, so the only option is to cover the inside of the exterior walls with a continuous layer of insulation. The rigid insulation acts as an air/moisture barrier, and it should be taped to create a comprehensive seal. Additional insulation can be added using bat insulation or fiberglass, spray foam, and cellulose insulation.
Insulation is essential for improving energy efficiency, saving money on energy bills, and making the home more comfortable to live in. In your climate zone (zone 5), code requires insulation of concrete block and other mass walls to at least R-13 if all insulation is on the exterior. Before insulating, coat the exterior of the walls with fluid.
The best insulation for concrete block walls is either spray foam or injection foam insulation. Foam insulation is the best option for concrete block walls because it creates an air seal, making the space more comfortable and energy efficient. Other options for insulating concrete block walls include spray foam insulation, injection foam insulation, polystyrene beads, foam boards, and loose-fill masonry.
The article also discusses the process of insulating exterior walls, including removing trim from windows, door casings, baseboards, crown molding, and ripping drywall and studs off the block walls. The author recommends adding 4 inches of rigid foam insulation to the exterior wall for an insulation rating of about R24.

How do you insulate a cold exterior wall?
SprayCork is a popular choice for insulated exterior wall coatings, as it effectively retains heat without requiring adjustments to existing fittings. Its natural cork-based formulation insulates cold walls from the outside, preventing internal heat from escaping. This results in a snug home even in cold winters. An internal coating or external spray cork render can save up to 15 heating bills. The material is breathable and moisture-resistant, making it an excellent solution for insulate your home and eliminate damp issues.
How to make concrete walls warmer?
Insulating concrete block walls can be done using various materials such as spray foam insulation, injection foam insulation, polystyrene beads, foam boards, and loose-fill masonry insulation. The choice depends on whether the walls will be covered or exposed, such as in a remodel or new build. Spray foam insulation is recommended before drywall is installed and studs are furred out, allowing the foam insulation to get behind the studs to prevent thermal bridging.
How do you insulate an existing exterior wall?
Insulating exterior walls can be done without removing the siding by cutting holes in the studs and spraying foam or cellulose into the holes. This process can be done by replacing the cutouts, filling the holes with wood filler, sanding smooth, and painting the siding.
Basement walls can be insulated using foam board, spray foam, blown-in, or spray foam insulation. For finished basements with sheetrock insulation, contractors use similar methods to retrofit exterior wall insulation installation. Holes are cut for insulation installation, then patched and painted over.
Additional insulation can be added to attics, under the roof, or loose fill insulation like fiberglass beads, cellulose, or rock wool. Loose fill insulation should be added between 7 to 12 inches, meeting the requirement for older homes.
How to warm up an outside wall?
To make walls warmer, add extra insulation to your property, which can be costly depending on the size of the problem. For older solid-walled properties, investing in an external insulation system can be an effective solution, but it may be expensive. If your home has wall cavities, fill them with insulating material to prevent heat loss. This is a more affordable option and can be highly effective. If you already have cavity insulation installed but experience cold walls, replace it with a new one.
If you cannot install insulation, find other ways to reduce moisture on cold walls. In summary, adding insulation to your walls can help prevent condensation and dampness, but it’s essential to consult a local cavity insulation removal specialist for advice.
What is the best insulation for exterior concrete walls?
The insulation of concrete block walls can be achieved through the use of spray or injection foam, which creates an air seal and thereby enhances the comfort and energy efficiency of the enclosed space. The two methods of installation differ in their respective approaches. The initial method entails the injection of insulation foam into the cores of concrete blocks, representing the most efficacious approach to insulation.

Do I need a vapor barrier on exterior wall insulation?
Building codes mandate the use of vapor barriers with insulation to improve indoor environmental quality and energy efficiency. Building scientists recommend this method, as it protects against diffusion. Polyguard recommends a quality air barrier system to limit infiltration, exfiltration, and moisture accumulation in the building envelope. Contact Polyguard professionals for more information on when to use a vapor barrier with insulation.
How to reduce heat from a concrete wall?
Heat proofing paint is a chemical solution that can be applied to concrete walls to reduce heat. It is easy to apply and comes in various forms, such as aluminum foil, PU foam spray insulation, water sprinklers, mineral rocks, metal shade, clean roof, and applying primer. In Pakistan, around 99 homes are made of concrete due to cheaper cement and concrete raw materials and expensive wood. However, concrete buildings can have defects, especially during heat waves.
Advances in science and technology have made it possible to find solutions to reduce heat from concrete over walls. One such solution is heat proofing paint, which is the easiest to apply and comes in a chemical form.
Do you need a vapor barrier between concrete and insulation?
Moisture build-up in a basement is a common issue, and proper basement insulation, moisture barriers, and wall sealants can help prevent condensation and damage to the building. When building a new house or repairing a basement, it is most effective to run a moisture barrier directly in the structure. Place vapor barriers on foundation walls before installing posts and primary insulation. Proper use of basement insulation, moisture barriers, and wall sealants can keep the basement dry and safe.
Melt is always present in modern homes, including water in the ground, condensation, dampness, and moisture from stoves or showers. To waterproof a basement, more than just concrete is needed. Water vapor can pass through the concrete from the subsurface or indoor air, and can condense if it passes through walls, ceilings, or other obstructions. A vapor barrier is a material used to prevent water vapor from penetrating a wall, ceiling, or floor during cold winters.
The intelligent vapor barrier adapts to wick moisture away from the wall, regardless of humidity levels outside or inside the wall. Drywall or green foil is not resistant to moisture trapped in the barrier.
What is the best insulation for exterior walls?
In cold climates, closed-cell spray foam is the best insulation for exterior walls due to its high R-value per inch, which effectively resists heat flow and serves as an air and moisture barrier. Insulating exterior walls from the inside is possible, often done in existing homes where exterior modifications are impractical. Options include blown-in cellulose for filling existing wall cavities and spray foam insulation for excellent air sealing. The R-value of the best insulation for exterior walls varies by insulation type and wall structure, and it’s beneficial to choose an R-value that meets or exceeds local building codes.
Typical R-values include fiberglass insulation (R-13 to R-15 for 2×4 walls, R-19 to R-21 for 2×6 walls), foam board insulation (R-4 to R-6 per inch), spray foam insulation (R-6. 5 to R-7 per inch), andcellulose insulation (R-3. 5 to R-4 per inch).

Simply backfilling with granular material is a ticking time bomb, depending on your soil. Maybe it’s 40 years, maybe it’s 70 years. But sediment and clay will follow water into that granular material where it will deposit and eventually clog it up, at which point you’ll be dealing with the effects of hydrostatic pressure on your foundation, which will crack it and maybe bow it. Another thing, rigid foam placed in a single layer will shrink, leaving gaps at the seams, which is where your foundation wall will have cold spots.
