How To Insulate Concrete Walls

How to insulate concrete walls? Regardless of what type of wall blocks you decide to use for your home, never lose sight of the fact that they are permeable.

That is, clay or concrete bricks are used as building blocks as it does not make a difference in the end.

They are still giant bricks that need to be treated with care when constructing your own house as air could seep into the cracks at any point. I will show you how to insulate a brick cottage house in simple steps.

How To Insulate Concrete Walls

different ways to insulate concrete walls

Insulating a concrete wall is vital to keeping cool air inside and hot air out, but there are several ways to achieve this.

You may choose decals or paint to do the job, with some opting for both as a more durable measure in the long run.

Of course, the choice is yours, and you know best what will work for your situation at home.

1. Injection foam insulation

We begin by drilling holes in the relatively easy walls to reach. This makes it easy to fill up the insides of the concrete bricks, using a center punch tool as a way to insert the sealant on all sides of the very center of each brick.

Instead of thinking about tubs of concrete (which is less efficient for smaller projects such as this) and what’s more, allows you to create bonds with adjoining concrete blocks!

The great thing is that this technique completely seals off any cracks in your wall – making it one of the best ways to keep out those cold drafts.

Because insulation foam expands and fills out all sorts of holes, air voids cannot get inside so easily anymore as a result.

2. Polystyrene Beads

This technique is typically used at the top of cavities between your concrete wall and any other walls where it has not been poured in and exposed.

This is because when the polystyrene beads are poured over the air voids above, the foam will already be there once you build your house.

There is one disadvantage to using this type of foam: they need to be trimmed. It will sprout quickly once it becomes free from its confines, but this can also be an advantage.

It provides insulating qualities for any ceiling space that may have lost its natural insulation properties by being removed for piping or similar items to be fitted through them.

3. Foam Boards

Use special glue for this material on the top of the foam board. Use a knife or caulk gun for this purpose.

When sealing the seams, keep an eye on them and be sure that the opening is sealed tightly, as otherwise, there will be water getting in.

Otherwise, you can elect to use vents or windows in your home to help prevent moisture on your wall and ceiling surfaces where it may lead to mold and mildew growth at a later date.

But if you don’t want to go the vents or window route, you can elect to add insulation kits to your exterior walls that enable you to seal air leaks out of your home.

4. Room Walls

Before framing the wooden (block) wall of your room, it’s important to consider the installation of insulation. This can be solved simply by installing the wall with furring bars.

After this is done, insulation can be applied. Like framing a model wall, this procedure has an exception in terms of its supports: here, you attach foam – and not wooden pins – in its entirety from top to bottom.

This type of industry-standard solid wood will give standard one ¾ inch spaces that are then trimmed and filled with rigid foam insulation.

FAQs

Does concrete block houses warm?

Yes, they are. Insulated Concrete Block walls keep out the cold during winter (or insulation foam or spray foam in hot climates) and heat during summer (or cooled with ventilation).

For this reason, they are often used above-ground levels, such as when framing a basement wall against concrete or insulating basement walls.

Does concrete block walls energy efficient?

They are only efficient if we insulate them to prevent air movement into the interior. If they aren’t insulated well enough, their energy efficiency will not be as good as possible.
