In the era of climate change and an ongoing energy crisis, external thermal insulation has emerged as one of the most effective solutions for enhancing building energy performance. In this article, we will explore in depth the benefits and application process of external thermal insulation, with a special focus on the inverted insulation system.
What is External Thermal Insulation?
External thermal insulation is a technique applied to the outer shell of a building to improve its thermal performance. This method involves installing insulation materials on the exterior walls, roofs, and other structural elements. The Inverted Thermal Insulation System The inverted insulation system is particularly effective and is mainly recommended for sloped surfaces like roofs.
How Does the Inverted Thermal Insulation System Work?
In the inverted thermal insulation system, the order of layers is different from traditional methods:
1. Waterproofing is applied first.
2. Insulation is then placed over it.
This method offers additional protection to the waterproofing layer, as the insulation acts as a shield against weather conditions and mechanical stress.
Choosing the Right Insulation MaterialThe specific structure of the inverted insulation system makes selecting the right insulation material crucial. The material must be moisture-resistant, as it will be directly exposed to rainwater. Extruded polystyrene is an excellent choice for this system due to its hydrophobic properties.
The Process of Applying External Thermal Insulation
Applying external insulation requires attention and precision. Let’s go through the steps:
1. Surface Preparation: Cleaning and smoothing the surface, removing loose mortar.
2. Placement of Insulation Boards: Typically, graphite-expanded polystyrene (Neopor) or another suitable insulation material is used. Boards are adhered with special thermal adhesive.
3. Securing with Dowels: Special dowels are used for added support, depending on the wall material.
4. Installation of Corner Guards and Drip Edges: These components protect the edges and improve water runoff.
5. First Coating Application: Applied with a notched trowel to fully cover the insulation boards.
6. Placement of Mesh: Reinforces the coating and prevents cracking.
7. Surface Smoothing: After at least 24 hours, the surface is sanded to ensure adhesion for the final plaster.
8. Final Coating: A high-strength primer and acrylic plaster are applied in a thickness of 1.5 to 3 mm.
Advantages of External Thermal Insulation
External thermal insulation offers multiple benefits:
• Energy Savings: Reduces energy consumption by up to 60%, with a typical cost payback period of five years.
• Aesthetic Enhancement: Significantly improves the building’s exterior appearance.
• Elimination of Thermal Bridges: Provides continuous insulation, eliminating points of heat loss.
• Durability: Excellent resistance to impacts, abrasion, thermal changes, and standing water.
• Consistent Performance: The system’s performance is not significantly affected by changes in moisture and temperature.
• Protection of Structural Elements: Protects the building’s structural elements from weather, extending their lifespan.
• Improved Indoor Climate: Helps maintain stable indoor temperatures, enhancing occupant comfort.
Conclusion
External thermal insulation, particularly the inverted insulation system, is an excellent investment for any building. It offers substantial energy savings, improves living conditions, and increases property value. With proper application and material selection, external insulation can provide long-term protection and energy efficiency while also helping to protect the environment by reducing carbon emissions.
In an era where energy efficiency is a priority, external thermal insulation emerges as a smart and effective solution for energy upgrades, offering benefits for both property owners and the environment.
