How to Insulate a Cold Wall from the Inside

how to insulate a cold wall from the inside

From higher energy bills to constant chills during the winter months, cold walls are a common issue in homes across the UK. They’re precisely what the name suggests – walls that are uncomfortably cold to the touch, typically located at the edges of buildings where they separate the indoors from the outdoors.

Struggling with a cold wall in your home? The good news is that it’s easy to insulate cold walls and keep your home warm and cosy all winter long. In this article, we’ll discuss the issues associated with cold walls and their causes, as well as explore solutions to insulate them from the inside and outside.

Cold wall, cold home

As mentioned above, cold walls can compromise the energy efficiency and thermal properties of your home. These types of walls are cold primarily because they lack proper insulation, which allows heat to escape from internal spaces. Here’s a closer look at the issues cold walls can cause and why it’s worth investing in insulation:

Higher energy bills

Cold walls make it challenging to maintain a comfortable indoor temperature, even with an efficient heating system. This can force residents to turn up the thermostat or run heating for longer periods, a pattern that can increase energy consumption and send bills soaring.

Dampness and mould

Cold surfaces are more prone to moisture, which can result in condensation on your internal walls. Over time, this can lead to problems with damp and mould. This can not only compromise the structural integrity of your home but can affect your health and cause issues like respiratory infections, allergies, asthma and immune system problems.

Insulating your cold walls

Cold walls can take a toll on your comfort, health and the structural integrity of your home. Insulation is the key to fixing the problem and can be done either from the outside or from the inside. Let's explore both options.

How to insulate a cold wall from the inside

Convenient and cost effective, insulating cold walls from the inside is often done with panels or boards. While effective, the solution can be bulky and may reduce living space within your home. Another option is installing a thermally efficient coating over your interior walls. Coatings are thin but highly efficient and can significantly improve insulation.

At Total Trades, we use SprayCork to insulate cold walls from the inside. The final coating is just 8mm thick, so it doesn’t impact the size of your room. It’s also damp-resistant and noise insulating.

External insulation for cold walls

Alternatively, you can opt for external insulation – a solution that can be just as effective as panels, boards and internal coatings.

Cavity wall insulation is a traditional method used to insulate exterior walls, though it’s unsuitable for solid structures without an internal gap. It’s also unsuitable for walls exposed to heavy rain and wind, elements that can compromise insulation properties.

Insulation boards or panels can also be installed on the exterior of your home. These can work in some homes but can be bulky and may require adjustments to external fittings, which can complicate the installation process and add to the total cost.

By far, the most effective solution is an insulated exterior wall coating – again using SprayCork. A practical alternative, the coating is applied to the outside of a cold wall and effectively retains heat without the need for adjustments to existing fittings.

Choose spray cork for effective, long-lasting insulation

Looking for effective, long-lasting insulation for a cold wall? SprayCork has a natural cork-based formulation to insulate cold walls from the outside and prevent internal heat from escaping. The result? Your home will stay snug even in the coldest winter snaps.

An internal coating or external spray cork render can also slash heating bills by up to 15%. The material is breathable and moisture-resistant, making it a great way to insulate your home and eliminate damp issues.

SprayCork: An eco-friendly solution

When it comes to performance, SprayCork is best in class. The award-winning product can be applied externally as a cork render or internally with a plaster overskim. Highly versatile and available in a variety of colours and textures, SprayCork can cover a range of surfaces. Because the coating is thin and unobtrusive, there’s no need to adjust fixtures like gutters, downpipes, windows and doors. Internally, you get a thin, plaster surface that can easily be decorated.

Why choose SprayCork to insulate your cold wall? Here are a few reasons why the product is loved by homeowners across the UK.

Natural and sustainable

Cork is a natural and renewable resource, stripped from the bark of cork oak trees without causing serious damage. The process doesn’t require felling and instead allows the trees to grow back and provide more cork.

Crack resistant

Sprayed cork is flexible and won't crack, even when applied over existing render.

Reduces heating bills

The cork coating prevents heat from escaping from internal spaces, a benefit that can reduce energy bills by up to 15%.

Mould and condensation resistant

It’s also breathable and resistant to condensation, which can help prevent issues like mould, damp and water damage.

High durability

Insulate your cold wall with SprayCork and enjoy a 25-year warranty on the render.

Good sound insulation

From traffic to noisy neighbours, SprayCork render can absorb up to 38dB of noise. This helps contribute to a quiet and peaceful home.

Fire resistant

The impressive breathable properties of SprayCork make it fire resistant and provide an added layer of safety.

Easy repairs

In the unlikely event that your SprayCork coating requires repairs, it’s easy to patch small areas without re-rendering the entire wall.

Extensive range of colours

SprayCork comes in a wide range of colours, making it easy to customise your project and choose a solution that matches the architectural style of your home.
