Insulating a home’s exterior walls with insulation can make it possible to insulate it. This can increase thermal performance and decrease energy consumption. EWI has many benefits for construction and renovation.
Comforts at home
Comfort is the most important factor for our health and well-being. A healthy and beneficial environment is one that makes its inhabitants feel comfortable.
Comfort refers to a state that is well-being and is determined by the environment in which it is built, decorated, furnished, and maintained. It is important to choose the right materials and how they are used. This will determine the interior’s quality and provide comfort for its inhabitants.
These four elements are key to comfort. They all contribute to the goals that building materials should achieve:
1 – What is the work involved in external insulation?
External Wall Insulation (EWI), is a process that adds several layers of render to the exterior walls of a house.
Insulation layer: mineral wool, polystyrene and resole foam
glass fibre matting
Primer and undercoat render
topcoat (paint, render, etc.)
The location of your home, its aspect, and local weather conditions will determine the fitting method (adhesive or nails, pegs, etc.
The type and condition of the substrate (external wall) will also influence the product solution and the fitting method.
During the work, the home remains habitable. The interior area does not shrink, unlike internal insulation which can reduce the area habitable by up to 7 percent
EWI work takes a different amount of time depending on the renovation area. For a 100m2 house, it takes on average 3 weeks.
2 – Improving the homes thermal performance
External wall insulation increases the walls’ thermal inertia. EWI reduces heat loss by adding insulation layers to the walls.
This improves your home’s thermal comfort
Reduces heating costs
Limits CO2 pollution
Accessories (heat pump and air-conditioning fans, etc.) have lower energy costs.
3 – More comfortable living areas
Heat loss through walls can cause excessive dampness in a house. Water vapour condenses in cold walls and at the corners with low insulation. Thermal bridges are where damp can form. This results in plaster and paint deterioration, wallpaper falling apart, and mite and mold growth. Damp homes can cause or exacerbate respiratory issues.
The effects of condensation are minimized by effective external insulation. It also eliminates many thermal bridges.
Thermal bridges can account for as much as 40% of heating power usage and 5 to 25% heat loss.
