How to Insulate a Concrete Block House The Easy Way

how-to-insulate-a-concrete-block-house

Concrete has been used as a building material for over 100 years and, in some areas, it is commonly used for home construction. Generally, it’s made using products like cement, stone or quartz – mixed with water.

Chances are, you have seen concrete block homes in your neighbourhood without realising it, as many concrete homes have external coverings and finishes, to make them appear more attractive. With that in mind, we’re going to tell you how to insulate a concrete block house!

Concrete blocks come in a range of shapes, and they can be hollow (with two or 3 voids or cores) or solid in construction. In fact, they’re ideal for basement walls and foundations when used correctly, as they are far more durable than mixed and poured concrete.

Concrete blocks can also be used to quickly erect partition walls, with steel reinforcing rods used to fill the voids, and make walls stronger. Other benefits of concrete blocks include:

  • They’re usually virtually soundproof
  • They are resistant to extreme temperatures and termites
  • They provide insulation against heat and cold, reducing your energy usage

Because solid walls have no gap, heat bridges through the material to the outside. This happens even more quickly when the exterior brickwork of your home is wet

How Costly Are Your Concrete Block Walls?

Do you have a friend who lives in a modern property with cavity walls? You may notice their energy bills are a lot less than yours, and that it’s cheaper for them to heat their home. This can happen even if your properties are of a similar size and you’re with the same energy provider.

Strictly speaking, cavity walls trap heat better than solid walls, which is why most new-build homes feature this type of wall.

A cavity wall has a gap between the inner and outer layer of brickwork, which provides extra insulation for your home.

Because heat travels faster through brickwork than it does across dry air, a home with cavity walls maintains heat better than a home with solid walls.

Because solid walls have no gap, heat bridges through the material to the outside. This happens even more quickly when the exterior brickwork of your home is wet.

Answer – How to Insulate a Concrete Block House

If you’re wondering how to insulate a concrete block house, then we have the answer. When you think of insulation, you probably imagine blown-in cellulose, foam, and batts of fibreglass.

That’s because in the past, insulating concrete block homes meant adding interior wall insulation, by building another wall against the concrete, and insulating between the studs. Today, there is no need to lose out on valuable interior space, as you can use external wall insulation to insulate your concrete block house.

The masonry cream bonds chemically with the substrate, providing superior protection from dirt, water and microbial growth. This helps to improve your home’s thermal insulation, as a dry wall retains more heat than a wet one

External Solid Wall Insulation

When it comes to how to insulate a concrete block house with solid walls, applying the insulation material is a bit like waterproofing your home, leaving your wall completely dry, and resolutely resistant to moisture.

In fact, your walls will absorb up to 95% less moisture than an untreated wall! The material is easy to apply too, as it takes just minutes to spray or paint the outside of your home, causing minimal disruption to your daily life. Our insulation is also resistant to biological hazards, and reduces microbial growth.

Our insulation does not stop your home from breathing though. Although the material is not water permeable, air and vapour can still permeate, whilst moisture is given its marching orders – the perfect combination!

Revolutionary Home Logic Wall Insulation

Home Logic Wall Insulation is painted or sprayed onto the exterior of your home. It may appear creamy at first – it’s usually obvious that something has been applied to your walls.

However, it takes just minutes for the product to sink into masonry, in much the same way that moisturiser sinks into skin, forming an invisible barrier against external elements.

This completely transparent barrier acts similarly to a waterproof jacket, penetrating up to 17mm into your home’s brickwork, and combating the absorption of water by over 95%.

If you apply external wall insulation on cavity walls, it will prevent moisture from even entering the outside brickwork in the first place. This provides an effective solution for water resistance, protecting your property both inside and out

Why Would You Even Consider Wall Insulation?

If you’re wondering how to insulate a concrete block house, then external wall insulation is the answer. Ever wondered why your energy bills are sky high? Your home’s construction could have a lot to answer for.

Did you know that up to 25% of your home’s heat can be lost through the walls? Warm air inside your home naturally travels towards the cold, outside air through brickwork – a process commonly referred to as thermal bridging.

Walls without insulation are very bad at preventing thermal bridging from taking place. In particular, older buildings, or listed properties with solid walls, can experience a high rate of heat loss from the interior.

Modern cavity walls, often present in new-build properties, are a little better at trapping heat, due to the space between the outer and inner layers of brickwork. But when you consider that the U-Value for cavity walls is still only 1.5 W/m²K, it’s easy to see that this is very low compared to the values of an insulated wall.

Hacked Off With Price Hikes? Insulation’s the Answer

As energy prices continue to rise, losing this amount of energy and heat from your home simply isn’t affordable. Lack of insulation could be costing you hundreds of pounds a year!

Older properties will suffer more than new builds, and if you own an older property with solid wall construction, then it is even more important to have it regularly inspected, to ensure it is as energy efficient as possible.

Installing external wall insulation not only boosts the thermal efficiency of your home, it also protects your home’s façade from dirt and moisture, and refreshes the exterior of your home, ensuring that it looks suitably impressive, for years to come.

Using our product will protect your home for up to 20 years, which can cut maintenance costs, and eliminate the need for further exterior treatments.

Not to mention that exterior wall insulation can also effectively sound-proof your home, reducing outside noise, and improving interior acoustics, so that home cinema system you purchased will sound even better!

Works Just as Well on Cavity Walls!

Just because cavity walls carry existing insulating properties doesn’t mean they too cannot benefit from an application of external wall insulation.

Cavity wall insulation, as it is traditionally recognised, is the process of filling the gap between the outer and inner shell with some form of insulating material.

In this approach, small holes will be drilled in carefully selected areas of your exterior brickwork. A series of hoses will be used to then pump insulating material into these holes, and into the cavity gap.

This method is not always effective, and can cause some unwanted side effects – such as moisture build-up and increased thermal bridging.

The better alternative to cavity wall insulation is to apply a solution to the outside of your home instead. Installing a material within the cavity allows moisture to access the cavity, and, consequently, transfer to the interior reaches of your home.
