What Kind of Insulation for Exterior Walls Should I Use

What kind of insulation for external walls should I use? This is a very common question from families and individuals that live in properties built with solid walls.

Most buildings constructed before 1930 were made with solid walls, as this was the norm back then. These wall structures do not contain the same gap of air that is found within cavity walls, which can be injected with insulation. Therefore, the best way forward with a solid wall, is to insulate it externally.

The purpose of insulating the outside of your property is to slow the movement of heat through your walls.

This dramatically reduces heat loss, and the need for manual heating within your home.

This isn’t to say that only solid walls can benefit from external wall insulation. Cavity walls can maintain and improve upon their existing thermal qualities even further with the application of external wall insulation.

Let’s take a look at how both types of wall can benefit from exterior insulation, and what kind of insulation would work best for your external walls…

The Outmoded Approach to External Insulation

The old-fashioned way of insulating the outside of your home generally involves fixing a wooden lattice to your external walls. This is to hold some form of solid insulation in place. Then, a render or piece of cladding is fixed over the top.

A wide variety of finishes are available for this method so that you can obtain the external façade you desire.

However, in truth, this is not the best approach when it comes to the question – what kind of insulation for external walls should I use?

Why is not the best? Well for starters, this will add depth to your walls, which can make passageways and driveways narrower in a lot of cases. Guttering and drain pipes may need to be shifted outwards slightly, to accommodate this extra space filler.

All of this will radically alter the external appearance of your home. Is this something you really want to do with your property? Changing the appearance of your home may require prior planning permission too.

External Wall Insulation on Solid Walls

Solid walls only really offer the choice between an external coating, or internal insulation. The latter option is best achieved with Home Logic Spray Foam Insulation, and be easily applied by our professional team of insulation specialists.

However, this option can take away some of your floor space, and the application process may disturb the daily running of your household as well.

A better alternative is to opt for external wall insulation, which will ensure your solid wall repels water absorption, and prevents as much heat loss as possible.

A special coating is applied to the outside walls of your home. This coating prevents moisture from attacking or penetrating your masonry, protecting it from the outside elements for years to come.

This is by far the most effective method of insulating a solid wall structure, especially within properties that are getting towards 100 years old.

External Wall Insulation on Cavity Walls

External wall insulation on cavity walls is just as effective, even though a cavity wall carries existing insulating benefits. By applying a coating of external wall insulation, you can make your cavity wall even more effective at trapping heat than it was to begin with.

There is a cheaper method to insulating a cavity wall and that is to fill the cavity with some form of insulating material. This usually takes the form of beads or some type of spray foam.

However, this approach is known to throw up some distinct disadvantages. The most common issue relates to moisture. Putting a material in the gap between the outer shell and the inner shell effectively creates a bridge for moisture to travel across, rending the cavity almost useless.

To avoid a series of complications later down the line, we strongly advise against this type of application.

This method can cause structural damage and may even encourage rapid heat loss from your home instead of protecting it. This is known as thermal bridging in our industry and is counterproductive when it comes to insulating your home!

By far, the better alternative is to apply external wall insulation. This approach prevents moisture from even entering your masonry in the first place, so it doesn’t have the option to cross the bridge either.

The Modern and Sophisticated Method

What kind of insulation for external walls should you use? One that is easy to apply, and offers plenty of benefits, with very few drawbacks. So move with the times and purchase an effective masonry cream!

This material is sprayed, or painted, onto the outside walls of your home. Within minutes, the product begins to sink into your masonry, similar to the way cream dissolves into your skin. Once completely sunken, the cream turns invisible, and creates a barrier of protection against rainwater and contaminants.

But what does this achieve? Well, the best way to describe it is like putting a big waterproof jacket over your home!

The chemicals within the product bond to the substrate of your brickwork, protecting it from water, dirt and micro-organisms. Dry walls are much better thermal insulators than wet walls, so your property’s thermal efficiency is greatly improved.

This is a much more effective and easier method of insulating the external walls of your home. It does not involve cladding, rendering or any dangerous substances. It is as easy as spraying liquid onto a wall!
