External Thermal Insulation (ETI) Systems
Looking to improve the thermal comfort and energy efficiency of your project, reducing energy costs for your client or future tenant? External Thermal Insulation (ETI) systems provide the energy efficiency your building requires while responding to increasingly rigorous thermal building standards and norms worldwide. By adopting a sealed exterior layer of insulation, ETI systems allow for less expensive retrofits and renovations of older buildings while also offering a cost-effective insulation solution for new buildings and homes.
For any architect, whether embarking on an entirely new project or looking to renovate an existing building, energy efficient insulation is a priority. City governments and private organizations are looking increasingly to buildings that respond to environmental norms such as LEED, BREEAM or ABCD+. External Thermal Insulation (ETI) systems answer that call by being designed to meet thermal performance requirements like 2012TR (France) as well as future demands for zero net energy and positive energy construction.
Why use an ETI system?
External Thermal Insulation (ETI) systems (also known as External Wall Insulation systems) place insulative material on the exterior of existing walls, with a finished, textured facade added to weatherproof and complete the solution. ETI systems maintain the following four characteristics:
Key features of ETI systems
Minimal disruption to existing inhabitants. Ideal of renovation and restoration projects, ETI systems allow undisrupted occupation of public or private housing and office buildings.
Limited supplemental work. With exterior insulation systems, plumbing and electric systems do not need to be displaced, ensuring a more efficient and cost-effective retrofit.
Responds to environmental norms, both current and future. By not only increasing thermal efficiency and comfort, but also reducing humidity and better protecting buildings, ETI systems respond to a whole host of environmental regulations.
Lower maintenance costs. Exterior facades provide protection while greatly minimizing the need for maintenance later in a building’s life.
Visually appealing: External finishes are available in a range of textures and colors so you can choose the perfect combination for maximum aesthetic appeal - modernising your home while ensuring its efficiency.
Exterior facade choices
There exists a variety of facade types which provide a maximum of choices for architects and designers according to specific needs, location and local building codes. The principal options include:
