Insulation Without Tearing Down Walls: The Essential Guide

Some would say that there is a standard and unconventional method for insulating existing walls. However, that mostly applies to internal walls. When you want to insulate exterior walls, there’s no need to tear down the walls. So, how can you tackle this project without affecting the structural integrity?

First, let’s discuss why you want, and need, to install insulation in your home? The predominant reason is to radically reduce your bills, by decreasing your dependence on external appliances to heat your home.

In the past several years, higher energy costs have made homeowners much more aware of the need for proper insulation.

When you rent a place, it might not be economically logical to insulate a place. However, when you own the property, insulation is a must. For older houses, insulation is even more crucial. Homes built before World War II do not have anything close to the today’s standards of insulation.

With this in mind, we’ve compiled the essential guide to applying insulation the easy way, without tearing down exterior walls to achieve it. Let’s begin!

 

Internal or External Wall Insulation: Which is Best?

We mentioned that there is no need for tearing down walls when you install external insulation. In some cases, you do not have to do that with internal walls as well. For example, spray foam insulation can be applied on the internal walls without tearing them down.

When you consider insulation, you are probably wondering should you install internal or external insulation. Let’s look at the benefits of each of those types in a little more detail:

 

Internal Wall Insulation

 

Benefits:

– Quick and easy to apply

– Ideal for projects that require decorating as well

– Cheaper than external insulation

Drawbacks:

– You lose internal space

– In some cases, you might need to move electrical sockets and light switches

– You must install a vapour control layer to prevent moisture and damp

 

External Wall Insulation

 

Benefits:

– Improves weather protection

– Provides noise insulation in addition to thermal

– No inconvenience to occupants

– Airtightness can be better preserved

– You can insulate a whole block at once

– You can achieve any value of insulation, depending on the thickness

Challenges:

– In some parts, planning permission is required

– It is more expensive, especially when the scaffolding is factored in

So, what type of insulation should you install? Both internal and external insulation come with their own set of benefits and disadvantages.

What you need to take into consideration is that the U-value of your walls should be less than 0.30 W/m2K, to meet current building regulations.

In any case, you should always ensure adequate ventilation is maintained. Your masonry should be able to “breathe”. This prevents condensation, and prevents moisture from accumulating on your property’s exterior.

 

Does Your Property Have Solid Walls?

 

Another important influence on your overall insulation decision is the type of walls you have. For example, are your walls made of brick, or some other material? Are your walls solid, or do you have cavity walls instead?

A general rule of thumb is that a solid brick wall is 22cm thick, while a cavity wall is between 27 and 30cm thick. A solid stone wall could be as much as 50cm thick.

We can offer both internal and external insulation, without tearing down walls. Here are the products, and here’s how we do it:

 

Internal Wall Insulation

In terms of internal insulation, we offer spray foam insulation. Spray foam is one of the most efficient insulation products on the market. The product decreases your heating and cooling costs by up to 35%.

The best part about spray foam is that unlike other internal wall insulation products, it does not sag, shrink, settle, or degrade in any other way.

Spray foam is a highly expansive material, increasing to up to 100 times its original size upon application.

By doing so, spray foam fills up all cavities, cracks, and holes, and creates a thermal envelope for your home. Because of its size and versatility, spray foam can be used for virtually any area; it can even be used to insulate hard-to-reach places, such as around pipework!

In terms of health, spray foam does not contain any toxic ingredients, does not accumulate dirt and dust particles, and does not absorb water. That makes the foam safe for installing in any property. Think of mould and condensation as a thing of the past.

Spray foam insulation has the highest R-value of any internal wall insulation on the market. Thanks to its high R-value, spray foam allows you to use less product. And it is lifespan is same as your building. As long as your building is standing, spray foam will protect it.

 

External Wall Insulation

If you want to install insulation without tearing down walls on the outside of your home, we’ve got the product for you. The biggest benefit of external wall insulation is that you do not lose any internal space in your home.

Our wall insulation is designed to reduce water absorption in walls by more than 95%, ensuring any potential condensation, damp, or moisture problems are eliminated.

External wall insulation also vastly improves the thermal conductivity of your home, preventing air and heat loss during Winter, and heat gain during Summer.

The lifespan of the product is 20+ years, enabling you to reap the benefits, for years to come. Wall insulation coatings will also reduce water absorption, make your masonry breathable and permeable to water vapour, as well as allowing air and moisture to pass through from one side to another.

Tests have shown that a 5% of damp content in cavity wall insulation will reduce the thermal resistance of your home by 50%. That means energy bills will go through the roof.

An underrated aspect of external wall insulation is its self-cleaning efficiency and ability. Because of the way the insulation bonds to the surface and substrate, it does not allow dirt particles to obtain a hold on the brickwork.

As a result, all of the dirt particles flow off with rainfall, while your masonry remains clean and attractive.

Wall insulation comes in a variety of different colours and textures. Our team will make sure you choose the best one for you.

Before applying the product, we will clean your outside walls, and then repair any cracks and damage in the walls. If needed, we will also re-render the walls, ensuring a sound, streamlined surface is achieved.

The coating is applied after all of the preparation work is completed. The protective wall coating is applied with industrial machinery, ensuring a fast and speedy application, and a high quality finish that’s set to impress.
