All you should know
Energy efficiency is one of the great challenges in contemporary architecture. In this context, ETICS has become a key solution to improve thermal insulation and reduce energy consumption in buildings.
In this article you will learn:
✔ What ETICS is and what it consists of
✔ How it is installed
✔ Advantages and applicable regulations
What is ETICS in Architecture?
ETICS (External Thermal Insulation Composite System) is a construction technique that consists of placing an insulating material on the exterior face of the facade, protected by a coating that covers it and integrates it aesthetically.
This system allows:
✔ Improving the energy efficiency of the building.
✔ Reducing heat loss in winter and gains in summer.
✔ Complying with sustainability and energy saving regulations.
Main components of ETICS
An ETICS system is made up of:
- Insulating panel (EPS, mineral wool, XPS, etc.).
- Adhesive and mechanical fixings to anchor the panel to the support.
- Base coat with mortar and reinforcing mesh.
- Final finish (acrylic render, decorative mortar or special paint).
Advantages of ETICS in construction
✔ Energy saving: Reduces heating and air conditioning consumption.
✔ Protection against thermal bridges: Avoids losses at critical points.
✔ Improvement of interior comfort: More stable temperature throughout the year.
✔ Greater durability: Protects the facade from the elements.
✔ Regulatory compliance: Makes it easier to adapt to the requirements of the CTE (Technical Building Code) and European regulations.
How is ETICS installed?
The installation of ETICS requires:
- Preparation of the support: Clean and repair the facade.
- Placement of insulating panels: Gluing and mechanical fixing.
- Application of the base coat and mesh: Reinforcement for stability.
- Final finish: Aesthetic and functional protection.
It is essential that the installation is carried out by certified professionals to guarantee the quality and durability of the system.
Applicable regulations
In Spain and the EU, the use of ETICS is regulated by:
- Technical Building Code (CTE), especially the DB-HE (Energy Saving).
- Construction Products Regulation (EU).
- Technical Suitability Documents (DIT) for specific systems.
ETICS in architecture not only improves energy efficiency, but also contributes to the sustainability and revaluation of buildings. It is an ideal solution for facade rehabilitation and new projects that seek to comply with increasingly demanding energy standards.
