Class 1 rated product and meets or exceeds all building code requirements. Liberty and [your employee] stopped out and provided an estimate. They were very professional and polite. No standing air, no gaseous moisture available to condense – or at least not more than the mass masonry can handle. Orlando is installed by drilling into the concrete block and injecting the foam directly into the wall cavity. This can be exacerbated if there are unusual details or irregular shapes along the wall, which alter the spacing of the cladding connectors and result in imprecise field cutting of the insulation.

But each of those studs is a break in the insulation that collectively can reduce the thermal performance of the wall by 20, 30, or even 50 percent.

That means that during cold outdoor conditions, most or all of the wall will be not only warm, but more likely to remain dry since condensation will not likely occur.

Unfortunately, concrete blocks also provide very little natural thermal resistance. Place the strips perpendicular to the floor every 16 inches and fasten them to the block using masonry or concrete screws.

Choose screws long enough to pass through both layers of foam and into the wall. If a brick building is insulated on the interior, the bricks will be colder and wetter in winter, and therefore more vulnerable to freeze/thaw damage.

Once the wall is insulated, the escaping heat that formerly passed through the bricks is no longer available to drive out the moisture. In some cases, repeated cycles of freezing and thawing can permanently damage the bricks, causing them to fall apart.

The work crews were courteous and very professional. Evaluating the wall to determine where foam can be injected and how to ensure that the foam fills all empty cells, cavities, and gaps in the wall.

Foam insulation does not settle and will not run out if a hole is cut into the wall, and it does not interfere with mason productivity.

It is a seamless, energy efficient, weather resistant and economical solution to the most challenging insulation environments. The foam reacts, expands, and cures in-place, forming a seamless insulating and damp proofing membrane. Standard anchors tie brick facing to the block wall. Afterwards, one of the installers advised they were finished and wanted me to see the finished product. A fire rated product and meets or exceeds all testing requirements of current standard building codes. For mass walls in particular, installing the insulation on the exterior optimizes the thermal mass of the wall which can improve overall thermal performance.

Early systems required very thick walls to utilize the heat capacity and maintain consistent interior temperatures. There is also greater flexibility with regard to attachment placement and configuration since a slightly bent or misaligned anchor can still be sprayed around without requiring realignment.

The type of vapor retarder required or prohibited by the code is based on the climate zone where the building is located and the classification listed in the codes based on perm ratings and material.

I vapor retarders have a very low perm rating of less than or equal to 0.1 and include materials such as sheet polyethylene or non-perforated aluminum foil.

This not only means that there is less concern about moisture condensation inside the wall assembly, it also means that the wall has more potential to dry out quickly in the event any wayward moisture does make it there since wall drying is permitted both to the interior and exterior.

Insulates, dampproofs and air seals in one step creating a seamless membrane. The floor joists are built into the inner layer of the brick. Hence, interior finishes will be protected, water will not run down and collect at floor penetrations. Closed cell will prevent air flow while open would not. Most don’t want to do this because brick is nice to look at. On the other hand, spray foam insulation can be used to insulate the open areas of the house including the attic, crawl space, and rim joist.

To reduce this air leakage, foam insulation works best because it provides heat resistance and an air seal. The injection foam creates an air barrier that helps to prevent drafts and energy loss through existing exterior walls. Styrofoam plugs and the siding is replaced. We have been installing injection foam in walls for more than a decade, and our efficiency, pricing, and quality is unmatched in the marketplace.

Remove all the trim from the exterior walls—window and door casings, baseboards, crown molding, you name it—and rip the drywall and studs off the block walls.

Install the drywall over the panels, finish it, then replace the trim. If insulating a brick wall on the interior can make the wall vulnerable to freeze/thaw damage, does that mean such walls should never be insulated?

But builders who want to insulate an old brick wall should proceed cautiously. Some bricks are more vulnerable to freeze/thaw damage than others; there are tests to determine whether your building has good bricks or bad bricks. Keep the foam panels held tightly to the edge of each strip to minimize air leaks. Overlap the seams by 6 inches and use nails or screws to fasten the vapor barrier to the furring strips. Even if you are happy with your unfinished basement, most building codes require foam insulation to be covered with 1/2-inch drywall to increase fire resistance.

To insulate finished walls without removing the drywall, try spray foam.


Shim the rigid foam in place with little chunks of foam. No standing air, no gaseous moisture available to condense – or at least not more than the mass masonry can handle. The double layer would still allow for some venting. You also have the moisture absorption capabilities of the brick as a back up, but the thought in the enclosures/envelopes world is you want to minimize air infiltration and put the spray foam as tight to the masonry as possible.

If you insulate at all you reduce the drying rate. Most don’t want to do this because brick is nice to look at. Insulating around them can make the joist ends rot. The best result is to clad the exterior with insulated panels and cap with stucco or vinyl siding. Removing it from the brick is barely possible and would take an absolute ton of effort. Cured close cell foam is pretty solid stuff. Closed cell will prevent air flow while open would not. The floor joists are built into the inner layer of the brick. If you are new here, please review the guidelines on the stickied post. No question is too stupid, too simple, or too basic. Moreover, less energy is available to help them dry out. It will allow the wall to dry to the inside, will closed-cell spray foam allow this? So stay away from this method if you have rain in the day with freezing at night. The problem has more to do with air leakage and air convection than vapor diffusion. My advice is to hire an insulation contractor experienced at insulating brick walls. In the end, the deciding factor should be the cost and life-cycle assessment for your options. That would allow the brick to dry to the exterior while preventing moisture intrusion. Plus fantastic thermal behavior in the summer with the added mass. Interior is plaster directly on the brickj and the basement is dry. While discussing this topic with a restoration mason, he mentioned lime wash, which is apparently suitable for old(er) load bearing masonry walls. I will personally be looking into mineral wool open joint rainscreen on the rear / side where the street presence isn’t as important to the block conformity.

It’s impossible to install poly in a way that is totally airtight — and in any case the trapped air would inevitably have moisture in it anyway.

Even if the work is perfect, you still have thermal bridging through the rafters. Question regarding the rigid foam. I stand by the advice given in this article. If you are sure that it is safe to proceed, then closed-cell spray polyurethane foam (sprayed directly on the interior of the bricks) makes more sense than rigid foam.

I have decided to frame 1.5″ away from the interior brick, with 1 ” spray foam sprayed directly on the brick, and then denim insulation in the 2×4 cavity 16″oc.

and that should only be used if you feel confident about your exterior water management details and the quality of your bricks.
