Exterior Insulation and Finish Systems (EIFS)

CPL

Exterior Insulation and Finish Systems (EIFS) are advanced wall systems designed to enhance energy efficiency and aesthetics in building construction. Comprising a layer of insulation board adhered to a substrate, followed by a reinforced base coat and a textured finish coat, EIFS provides an effective barrier against thermal loss while allowing for versatile design options. However, contractors who install EIFS face several environmental exposures, including moisture infiltration, UV radiation, and temperature fluctuations, which can compromise the system’s integrity. Additionally, the risk of mold growth and deterioration from prolonged exposure to harsh weather conditions necessitates careful installation and maintenance practices to ensure the longevity and performance of EIFS in various climates.

Environmental Exposures May Include:

Mold Growth
Concrete & Masonry Hazardous Materials
Volatile Organic Compounds (VOCs)
Waste Management

Mold Growth

Improper installation of EIFS can lead to mold growth. Gaps, cracks, or poorly sealed joints can allow water to penetrate behind the EIFS. In areas with high humidity, condensation can form on the interior surfaces of the EIFS, especially if there is a significant temperature differential. EIFS should include drainage provisions to allow any water infiltrating the system to escape. If moisture becomes trapped within the EIFS layers due to poor drainage systems or inadequate ventilation, it creates an environment conducive to mold growth. Mold growth could lead to third-party claims and cleanup costs for the contractor.

Concrete & Masonry Hazardous Materials

Concrete or masonry products may be used during substrate preparation. These products may include hazardous materials, such as sealants, etchants, coatings and emulsions, mortar admixtures, acids, chemicals used in the hardening of concrete, and cleaning chemicals for masonry and equipment. Spills, improper storage, and contact with stormwater can cause contamination of surface water, groundwater, and soils.

Volatile Organic Compounds (VOCs)

Some materials used in EIFS, like adhesives and coatings, may contain volatile organic compounds (VOCs) or other harmful substances. Accidental spills and leaks of adhesives, sealants, solvents, and cleaners at the jobsite, location of storage, and during transportation may cause third-party exposures and cleanup. Some products are flammable and may result in a fire that spreads and releases other contained materials and produces hazardous vapors.

Waste Management

Improper waste disposal can lead to cleanup costs and environmental tort liability. Materials such as sealants, adhesives, and solvents may be classified as hazardous waste and require special disposal procedures. Hazardous waste may also be inadvertently mixed with leftover pieces of insulation board, broken or damaged panels, and excess base coat or finish coat and disposed of improperly. Investigations for improper disposal at a disposal facility can result in potential liability for all parties that manifested waste to the facility.

Defense of third-party claims

Claims Scenarios & Examples

A courthouse developed mold after an EIFS system was installed. Moisture buildup caused greenish-black mold to grow around windows and saturate the sheetrock. The general contractor, subcontractor, and architect were ordered to pay a $12 million settlement.
A couple filed a lawsuit against their builder and subcontractor for using synthetic stucco in the construction of their new home. The homeowners claimed the EIFS system continuously failed and allowed water to leak into the insulation and framework of the house. The complex case lasted for several years, leading to multiple claims, an appeal, and large attorney fees for the contractors involved.
A homeowner was awarded over $1 million for the water damage to his home caused by EIFS. The defendant in the case, the general contractor, went out of business.
Residents of a community joined together to file a lawsuit against their builder, subcontractors, manufacturer, and distributor for issues caused by synthetic stucco. The suit alleged that the EIFS used on their homes led to major damage, including excessive water penetration that caused structural problems, termite infestation, and toxic mold. Over 80 families joined the suit, which is still ongoing.
A roofing contractor was hired to replace three roofs on top of buildings clad in EIFS. Following the completion of the work, one of the roofs started leaking after heavy rains and snowstorms, causing water infiltration. The owner sued the roofing contractor for negligence, property damage, and remediation costs. Although the roofs did not interface with the EIFS system and the contractor completed no EIFS-related work, the contractor’s general liability policy contained an EIFS exclusion and denied the claim.

Final Consideration

As a contractor you can be faced with the cost to defend yourself against allegations or legal action from pollution related events, regardless if you are at fault or not. Having the proper insurance coverage in place will help fund the expenses incurred to investigate or defend against a claim or suit and provide you with environmental claims handling expertise.
