![]() ![]() Concrete walls provide superior insulation, are much more stable, and their finish looks a lot better.į or new houses, you can use a concrete calculator to know how much concrete you need for all the walls. If you want something more robust, you should go with concrete walls. They pose so many problems, the least of which is providing inadequate insulation to the home. I f you are building a new home and have the budget, you would do well to avoid concrete blocks. These cavities can lead to airflow into a house, and injection foam insulation takes care of that for you. I njection foam insulation affords homeowners an added advantage in that it can get into crevices that are left open as the concrete blocks are mortared together. The foam is then injected into these holes and is continually injected until all the cavities are full. These holes have to align with the cavities left by the blocks as they were arranged and installed. When you choose this option, you will start by drilling holes into the wall. This is because there is no way of knowing how much material you need beforehand and you have to estimate whether the material you have poured is enough. The main problem with using loose-fill masonry insulation is that you cannot guarantee that all cavities have been filled. ![]() Because this material is very loose, you should not cut or drill into your wall because the insulating material would spill out if you did. It is used to fill the concrete block cavities from the top. This material is installed like the polystyrene beads mentioned above. When you use this type of insulation, the results are the same as if you used sand. This could lead to mould and mildew growth. Also, if the seal is not air-tight, air could move into and out of the home, which might cause condensation where the wall meets the board. Finally, you might want to use caulk around the seams of the board to ensure there are no air leaks, as these can affect its insulation properties. Then, all you have to do is place the board on the wall, taking extra care to ensure it is aligned correctly. I f you want to use foam board, the first step is to apply adhesive to the back of the board. Regardless, foam boards are still a good option to consider and are used on the exterior of the walls before the final finish is applied. W hen used on a house’s exterior, form boards do not provide the same level of thermal insulation as spray form does. S pray foam insulation is an excellent option for basements because most owners do not mind how the walls of their basements look all they want is to prevent thermal bridging. ![]() When this happens, those areas with a higher rate of heat transfer can compromise the wall’s ability to provide thermal insulation. When building a house, thermal bridging happens when a part of a wall transfers heat faster than other parts of the wall. The spray form is sprayed on the wall so that it can enter behind all the studs installed, which helps with thermal bridging. The spray foam is used to insulate the walls before the contractor puts the final touches on the drywall. T his is another popular option that is used in a lot of homes. This is because they are not held inside your walls by anything other than the concrete blocks themselves. The problem is that if you ever need to cut into walls for any reason, the beads will come pouring out. P olystyrene bead cavity wall insulation is an excellent option because it is relatively cheap and can be installed by anyone. Since this method of insulation has been used for a long time, it is likely that these beads are embedded into walls if the home is built using concrete blocks. The beads to be used are poured into the open block cavities at the top. T his option is used when the concrete block wall is open at the top. Fortunately, there are lots of different ways you can do this. If you want a home to remain at acceptable temperatures throughout the year by blocking the airflow through the concrete blocks, you have to insulate the walls. If you decide to use these blocks to build a home, you might have to insulate it as the temperatures might never get comfortable enough. Their main caveat is that they are porous, which means that they let air in, plus they are open on the inside. They are quite common as they allow the construction of homes to be completed relatively quickly. You may see insulating concrete block walls referred to as concrete block walls, cement block walls or cinder blocks. ![]()
