22 million homes across the UK are in dire need of upgrades to save energy. 8.5 million homes in the UK are considered ‘hard-to-treat’. This means that retroactive insulation methods, such as cavity walls, are not always possible.
External wall insulation (EWI), which is a method of insuring that a home is well-insulated, allows for the installation of insulation to the exterior of the home. This improves thermal performance and reduces energy consumption, which can lower energy bills. It also updates the aesthetics.
EWI systems are made up of several layers. You can choose from a variety of insulation boards that are suitable for different projects and their needs.
After attaching the boards to the wall, the system can be built using multiple coats that will include:
Render
Reinforcement mesh
Primer
Top coat or decorative finish
You can also choose a brick effect finish to preserve the character of your property.
Because all work is done outside, you don’t have to relocate during renovations. EWI is also less intrusive than internal insulation, which can decrease the interior space by as much as 7%.
These are five benefits to choosing external wall insulation as part of your project
1. It improves the thermal performance of buildings
EWI increases the wall’s thermal inertia, and reduces heat loss. This increases indoor thermal comfort, lowers heating costs and reduces CO2 pollution.
2. Comfortable living spaces are possible
The walls of a house can lose heat, which can cause damp. This can lead to plaster and paint deterioration, wallpaper falling apart, and possibly, mould development. Further, damp in the home can cause respiratory problems. A properly insulated home can reduce condensation and help to eliminate damp problems. Your home will be more comfortable in summer and cooler in winter, which is a win-win situation.
3. Reduces noise levels
Noise pollution can have a negative impact on our health and well-being. Installing an EWI system can help reduce outside noise, such as traffic. A quieter home will be more comfortable.
4. It makes your home more appealing
External wall insulation is a great way to revitalize your home’s appearance.
We offer a variety of durable and low-maintenance decorative finishes. There are more than 100 colors available if you choose to paint your finish. You can choose from brick-effect finishes or pebble dash in many different colours. Mineral renders can also be ordered, which can help you create a variety of architectural details like quoins or ashlars.
5. High-performance, more valuable build
It is important to think about the long-term effects of renovating your house. Potential buyers will be attracted to the house’s appearance and will also be pleased to learn that it is energy-efficient and low in heating costs. A well-insulated, thermally efficient house will be more appealing to potential buyers in the long-term.
