The Best EIFS Siding and Cladding Options

In this article, we will discuss the different finishing systems (siding/cladding) that can be used in Sto’s EIFS systems.

Exterior Insulation Finishing Systems (EIFSs) provide an insulated, finished surface that creates exterior walls with superior moisture and temperature control performance over other cladding products like brick, stucco, and cement fiberboard siding.

Simple-to-install, EIFS siding applies in multiple layers over an exterior sheathing to produce an energy-efficient, low-maintenance, fire-resistance, beautiful, and versatile exterior cladding. The typical layers (components) of EIFS include:

  • An air and water-resistive barrier over the substrate that stops air leaks and moisture from infiltrating the system.
  • Expanded polystyrene (EPS), extruded polystyrene (XPS), or mineral wool layers that add insulation and enhance energy efficiency.
  • A layer of fiberglass mesh that adds crack-resistance and provides reinforcement. It also protects against crumbling and cracks due to thermal expansion, shifting foundations, and freeze/thaw cycles.
  • A water-resistant base coat, embedded into the glass-fiber reinforcing mesh, applies insulation’s top, to provide a weather barrier.
  • A finishing coat or cladding surface that creates the color, texture, and protective nature of the structures’ exterior surfaces.

Unlike some EIFS systems, StoTherm® ci Wall Systems Drainable EIFS provides a more modern approach to EIFS technology with drainage that helps to prevent moisture from entering the wall cavity.

All long-lasting EIFS types should provide straightforward application and offer impact and condensation resistance, excellent energy efficiency, and design flexibility.

Impact Resistance

Designing EIFSs with a high-impact mesh substantially improves their impact resistance.

Condensation Resistance

EIFS insulation thickness should stop the interior air from reaching the dew point (the temperature that water vapor turns to water), in order to minimize condensation within the wall system.

Quality Sealants

Preventing water intrusion to the wall system must include proper installation of quality sealants.

Energy-Efficiency

All EIFS provide continuous insulation (CI) which lessens energy use, saves money, and meets today’s energy codes.

Design Flexibility

EIFS allows you to customize the aesthetic of the cladding system to fit the needs of your project.

A Modern Approach to the EIFS Technology Drainable StoTherm® ci Wall Systems EIFS

The International Building Code and ASTM International define traditional EIFS as a non-load bearing, exterior wall cladding system with an insulation board attached either adhesively or mechanically to the substrate, a reinforced base coat, and a textured protective finish coat.

StoTherm® ci Wall Systems Drainable EIFS improves on traditional EIFS technology by adding drainage to their wall systems. Our systems also include continuous insulation (ci), air and water-resistive barrier, and many performative aesthetics to create a sustainable, high-quality wall cladding. The durable and unique system sustains its curb appeal and saves money through lower energy bills.

Sto offers several StoTherm ci Systems, including four StoTherm ci Hurricane Impact Systems.

StoTherm® ci XPS

Long-lasting and high-performing StoTherm® ci XPS incorporates high R-value extruded polystyrene insulation into the wall system and StoGuard® air and water-resistive barrier, ensuring durability and thermal efficiency.
