Is Laminate Flooring Toxic? Ultimate Guide Unveiled

In recent years, concerns about the potential toxicity of laminate flooring have been growing. This data-driven ultimate guide aims to explore whether laminate flooring is toxic and provide valuable information for homeowners to make informed decisions.

Laminate flooring, a popular option for home renovations, is known for its affordability and easy maintenance. However, it’s essential to understand the materials and chemicals used in its production and their potential impact on indoor air quality and health.

Understanding Laminate Flooring

Laminate flooring has gained popularity in recent years due to its affordability, durability, and ease of installation. In this section, we will explore the composition of laminate flooring, the different types available, and their potential impact on indoor air quality.

Materials and Construction

Laminate flooring is made up of four layers, each playing a vital role in its functionality and appearance:

  • Wear Layer: This top layer is designed to protect the flooring from scratches, stains, and fading.
  • Design Layer: The second layer features a high-resolution image, providing the appearance of wood, stone, or other desired patterns.
  • Core Layer: The third layer consists of a high-density fiberboard (HDF) or medium-density fiberboard (MDF), providing stability and support.
  • Backing Layer: The final layer acts as a moisture barrier, preventing warping or damage to the subfloor.

Types of Laminate Flooring

There are two main types of laminate flooring, based on the installation method:

  1. Glueless-Click: This type of flooring uses an interlocking system, allowing for quick and easy installation without adhesives.
  2. Glued-Laminate: As the name suggests, this type of flooring requires an adhesive to be applied to each plank or tile during installation.

Additionally, laminate flooring can be categorized based on its AC (abrasion class) rating, which ranges from AC1 to AC5. This rating helps buyers to understand the durability and suitability of the flooring for different levels of foot traffic.

Options that are considered eco-friendly, such as those with low VOC (volatile organic compound) emissions and formaldehyde-free adhesives, are available for consumers concerned about potential toxicity levels.

Sources of Toxicity

Formaldehyde Emissions

Formaldehyde is a toxic chemical commonly used in the production of laminate flooring. It can be released from the flooring into the indoor air over time. According to the U.S. Environmental Protection Agency (EPA), exposure to high levels of formaldehyde can cause adverse health effects, such as eye, nose, and throat irritation, respiratory issues, and even cancer.

The level of formaldehyde emissions varies depending on the product. Laminate flooring made with low-emitting materials or certified for low-emission standards, such as the California Air Resources Board (CARB) Phase 2 compliant products, poses lower health risks. Here is a table showing the acceptable levels of formaldehyde emission according to CARB Phase 2:

Product CategoryFormaldehyde Emission Limit (ppm)
Hardwood Plywood (HWPW)-VC0.05
Hardwood Plywood (HWPW)-CC0.05
PB (Particleboard)0.09
MDF (Medium Density Fiberboard)0.11
Thin MDF0.13

Volatile Organic Compounds (VOCs)

Volatile Organic Compounds (VOCs) are another potential source of toxicity in laminate flooring. VOCs are chemicals that vaporize at room temperature, and some of these can have harmful effects on human health. The Lawrence Berkeley National Laboratory states that many VOCs, such as benzene, toluene, and formaldehyde, can cause irritation, respiratory issues, and have been linked to long-term health effects such as cancer.

Similar to formaldehyde, VOC emissions can vary depending on the product. Choosing laminate flooring that is certified for low VOC emissions, such as products with GREENGUARD Gold certification, ensures a healthier indoor environment.


Phthalates are chemical compounds used as plasticizers in various products, including some laminate flooring. The Consumer Product Safety Commission (CPSC) notes that exposure to certain phthalates has been associated with reproductive and developmental issues. However, not all laminate flooring contains phthalates. In 2015, the major flooring retailer, Lumber Liquidators, stopped selling laminate flooring with phthalates in response to concerns about their potential health effects.

To avoid products containing phthalates, look for laminate flooring labeled as phthalate-free or certified by third-party organizations for their low content, such as The Resilient Floor Covering Institute’s FloorScore certification.

Health Concerns

Laminate flooring has become a popular choice for homeowners due to its affordability, durability, and aesthetic appeal. However, some health concerns have been raised about its potential impact on indoor air quality and human health. This section will discuss some of the potential health concerns associated with laminate flooring.

Asthma and Respiratory Issues

One of the primary health concerns associated with laminate flooring is the potential for the release of volatile organic compounds (VOCs) into the indoor environment. These compounds can cause respiratory issues and exacerbate existing asthma symptoms. For example, formaldehyde is a common VOC found in laminate flooring, and it has been linked to respiratory problems and worsening asthma symptoms. A study from the National Library of Medicine found that formaldehyde exposure levels in homes with laminate flooring were higher than in homes without laminate flooring.


Laminate flooring can also lead to allergenic symptoms in some individuals. Due to its smooth surface, laminate flooring can accumulate dust, pet dander, and other allergens, which could lead to an increase in allergy symptoms. However, regular cleaning and maintenance can help reduce these allergens and improve indoor air quality.

Long-Term Health Risks

There is limited research on the long-term health risks associated with laminate flooring exposure, but some concerns have been raised about potential carcinogenic effects. As mentioned earlier, formaldehyde is a known carcinogen, and chronic exposure to high levels of this chemical may increase the risk of certain cancers. In 2010, the International Agency for Research on Cancer (IARC) classified formaldehyde as a Group 1 carcinogen, which means it is “carcinogenic to humans.”

While it is crucial to be aware of these potential health concerns, it’s essential to note that the formaldehyde levels emitted from laminate flooring are generally considered low and within acceptable limits. Also, advancements in manufacturing techniques have led to low-emission laminate flooring products that meet stricter indoor air quality standards.

Choosing Safer Laminate Flooring Options

In this section, we will explore various factors to consider when selecting safer and less-toxic laminate flooring. Some key aspects include certification and standards, as well as low-VOC and no-VOC options.

Certification and Standards

When shopping for laminate flooring, it’s crucial to look for certifications and adherence to specific standards that ensure safety and reduced toxicity. Some common certifications include:

  • GREENGUARD Certification – A program by UL Environment that sets strict standards for indoor air quality.
  • FloorScore Certification – A third-party certification by SCS Global Services, which tests flooring products for VOC emissions.
  • CARB Phase 2 Compliant – The California Air Resources Board has developed strict regulations for formaldehyde emissions in composite wood products, including laminate flooring.

Low-VOC and No-VOC Options

Considering low-VOC or no-VOC laminate flooring options can significantly contribute to a safer and healthier indoor environment. Volatile Organic Compounds (VOCs) are harmful chemicals emitted by various building materials, including laminate flooring.

Studies reveal that using low-VOC or no-VOC laminate flooring can improve indoor air quality (IAQ) and reduce the risk of health issues. The Federal Emergency Management Agency (FEMA) recommends an acceptable VOC concentration of less than 0.5 mg/m³. Laminate flooring products with low-VOC or no-VOC labels, as well as those certified by FloorScore and GREENGUARD, usually meet or exceed this guideline.
