External or internal wall insulation: advantages, limits and how to choose for your house or apartment in Belgium.
Why insulate external walls?
Poor insulation is the first source of heat loss in a home. External walls play a crucial role: a well-insulated facade guarantees significant energy savings, and more besides.
- You cut energy losses, and therefore CO2 emissions.
- You lower your heating bills in winter while keeping a pleasant indoor temperature, even in hot periods.
- You increase the value of your property by making it more energy efficient and more comfortable in the long term.
Internal insulation (ITI)
ITI is an effective method that delivers optimal thermal comfort. Its main drawback is space: fitting the insulation slightly reduces living area, by about 5 square metres.
It also requires emptying the room being worked on. It is worth considering when the facade cannot be altered or when you renovate room by room.
External insulation (ITE / ETICS)
External insulation is a complete alternative. Besides greatly improving thermal comfort, it rejuvenates the exterior look of the facade, for example with render in an almost unlimited range of colours.
It offers better protection against structural thermal bridges and, unlike internal insulation, causes no loss of space inside the house.
- Better protection against structural thermal bridges
- No loss of living space
- A refreshed facade protected from water infiltration
