EIFS Creative Facades, Transforming Architectural Design with Versatility and Innovation
December 20, 2024
Many still think of EIFS (Exterior Insulation Finishing Systems) as synthetic stucco. But that EIFS is so last century. Over the years, significant improvements have made it an excellent choice for a durable, energy-efficient cladding system. Today’s EIFS with drainage is transforming architectural design with versatility and innovation.
Applied in multiple layers over exterior sheathing, today’s EIFS provides outstanding insulation and moisture protection. The typical components (layers) include:
- An air and water-resistive barrier over the substrate that prevents moisture from infiltrating the system.
- An adhesive applied in vertical ribbons that adheres the insulation to the sheathing and provides a source of drainage between the AWRB and insulation board.
- A layer of insulation. Options include graphite-enhanced polystyrene (GPS), mineral wool, expanded polystyrene (EPS) or extruded polystyrene (XPS).
- A layer of fiberglass mesh with embedded base coat provides reinforcement. It will also help protect against cracks and crumbling due to shifting foundations, thermal expansion, and freeze/thaw cycles.
- The system finish furnishes the color, texture, and protective nature of the structures’ exterior surfaces. A primer coat may be recommended to improve finish coat coverage and promote uniform substrate absorption.
