It is possible to insulate your home with external wall insulation. This can improve the home’s thermal performance as well as reduce its energy consumption. EWI is a great option for both construction and renovation.
Comforts for the home
Comfort is the key to our well-being and health. Comfortable interiors are conducive to a healthy and productive environment.
Comfort is the state of well-being that results from the physical conditions of an environment. This includes how it is designed, constructed, decorated, and furnished. How materials are chosen and used can have a significant impact on the quality of interiors and therefore the comfort of its inhabitants.
Four key elements contribute to general comfort. These four elements are essential for building materials to achieve the following goals:
1 – What does it take to install external insulation?
External Wall Insulation is the application of several layers (or render) of insulation to exterior walls.
Insulation layer: Polystyrene or mineral wool.
glass fibre matting
Undercoat render and primer
topcoat (paint, render, etc.)
The local weather conditions, the altitude and aspect of the house, as well as the type of fitting (adhesive nails, pegs), will all affect the choice of method.
The substrate type (external walls), will also affect the choice of product solution and fitting procedure.
During these works, the home can still be used as a living space. The inside area of the home is not diminished, unlike with interior insulation, which can decrease the habitable space by as much as 7%
The area being renovated by PD Rendering & External Wall Insulation will determine the duration of EWI. On average, EWI works take three weeks for a 100m2 residence.
2 – Increasing the home’s heat performance
External wall insulation enhances walls’ thermal resistance. EWI is a wall insulation that reduces heat loss.
It improves the thermal comfort of your home
Heating costs are reduced
CO2 pollution is limited
Limits energy consumption of accessories (heat pumps, air-conditioning and fans)
3 – Comfortable living spaces
Heat loss through the walls is what causes excessive damp in a home. Water vapour condenses on cold walls, and in corners that are not well insulated. Damp can appear at thermal bridges. It causes paint and plaster to degrade, wallpaper to come unstuck and can lead to mites or mould growth. Damp homes can lead to or worsen respiratory problems.
A home with effective exterior insulation can reduce the effects of condensation and eliminate many thermal bridges.
Thermal bridges account up to 40% for heating power consumption, and 5 to 25% for heat loss.
