What is Solid Wall Insulation?
Solid wall insulation involves adding an insulating material to the walls of your home to reduce heat loss. There are two main types of solid wall insulation: internal insulation and external insulation.
- Internal Solid Wall Insulation: This method involves applying rigid insulation boards to the existing walls, or constructing a studded wall and inserting insulation between the studs. Internal insulation is often a more cost-effective option and can be installed room by room, making it easier to manage and control.
- External Solid Wall Insulation: This method involves adding a layer of insulating material to the outside of your home’s walls, typically covered with a protective render or cladding. While this option can be more expensive upfront, it offers additional benefits, such as improving the appearance of your home and providing extra protection from the elements.

Save Money and Reduce Heat Loss with External Insulation
Did you know up to 35% of heat loss occurs through uninsulated walls? With External Wall Insulation, you can drastically reduce this heat loss, keeping your home warmer and your energy bills lower.
At Smart Eco Homes, we make it simple and affordable for you to improve your home’s energy efficiency. External Wall Insulation acts as a thermal barrier, preventing heat from escaping through your walls and creating a comfortable indoor environment year-round.
How Does External Wall Insulation Work?
In the winter months, the insulation prevents the warmth from escaping, keeping your home cosy and reducing the need for constant heating. In the summer, external insulation can prevent heat from entering the home, keeping it cooler and more comfortable.
Benefits of External Wall Insulation
- Effective Noise Barrier
External wall insulation is also an excellent sound insulator, making it particularly useful in noisy areas. Whether it’s traffic noise from the street or sounds from neighboring homes, the insulation helps to reduce noise levels, creating a quieter, more peaceful living environment. - Protects Against Heat Loss
External wall insulation prevents heat from escaping through the walls, which can be a significant source of energy loss in older properties. By keeping the heat in, you’ll use less energy to heat your home, making it more energy-efficient and reducing heating costs. - Potential to Increase Home Value
Homes that are well-insulated tend to have a higher market value. The energy efficiency improvements and enhanced comfort provided by external wall insulation can make your property more attractive to potential buyers, especially in today’s environmentally-conscious market. - Warm and Comfortable Home
A well-insulated home is a warm home. With external wall insulation, your home will remain at a more consistent temperature throughout the year, offering comfort even during the coldest winter months. - Saving Money and Reducing Energy Costs
By reducing heat loss and making your home more energy-efficient, external wall insulation can result in significant savings on energy bills. Over time, the cost of installation is recouped through lower heating and cooling costs.
How Much Can You Save With External Wall Insulation?

The savings from installing external wall insulation can vary depending on several factors, including the size and type of your property, how much heat your home currently loses, and your existing energy usage.
However, external wall insulation generally offers substantial savings on energy bills by reducing the amount of heating required to keep your home warm.
On average, homeowners can save up to £460 per year on energy bills with external wall insulation. For larger homes or properties with poor energy efficiency, the savings can be even greater.
Additionally, insulating your home can lead to a reduced carbon footprint, making it a great option for those looking to lower their environmental impact.

Benefits and Considerations
While more expensive, external wall insulation offers additional benefits, particularly in terms of long-term energy savings and aesthetics. External insulation can:
- Enhance the Appearance of Your Home: External insulation can be covered with a range of cladding materials or a decorative render, improving the exterior of your home.
