Indoor air quality matters—flooring can release volatile organic compounds (VOCs) and formaldehyde into your living space. These chemicals often come from vinyl, laminate, engineered wood, MDF cores, particleboard, and adhesives. Resins and binders in luxury vinyl plank, carpet backing, or underlayments can all play a role in what you’re breathing indoors, whether at home, school, or work.
FloorScore and GREENGUARD Gold both test flooring for low chemical emissions, but GREENGUARD Gold sets stricter limits for sensitive spaces, while FloorScore focuses on hard surface flooring emissions. FloorScore, created with the Resilient Floor Covering Institute, applies to hard surface flooring like vinyl plank, engineered hardwood, laminate, and adhesives. GREENGUARD Gold covers a wider range of building materials and uses lower emission limits—something many schools and healthcare projects specifically require.
Knowing these differences helps buyers compare brands like Mohawk, Shaw, or Pergo without just trusting the label. Looking at how each certification measures VOCs and formaldehyde lets you pick flooring that fits your project’s needs and avoid empty marketing claims.
FloorScore is a globally recognized indoor air quality certification standard that identifies hard surface flooring materials and adhesives complying with strict VOC emission limits.It measures chemical emissions from finished flooring so builders can check if products hit defined air quality targets.
FloorScore® came from Scientific Certification Systems (now SCS Global Services) and the Resilient Floor Covering Institute (RFCI). SCS tests products in environmental chambers and checks results against limits based on California Section 01350 and similar standards.
FloorScore is widely accepted in the industry. It qualifies products for LEED v4.1, WELL, CHPS, and BREEAM credits, which a lot of commercial projects need. For manufacturers, this makes FloorScore a practical way into North American office, school, and healthcare markets.
The certification focuses on finished flooring, adhesives, and underlayments. SCS Global Services tests VOC emissions over time in controlled chambers, so the data reflects what happens after installation. For building owners, this means lower measured emissions in real-world spaces, supporting air quality goals.
FloorScore has a clear scope. It applies to hard surface flooring like vinyl, laminate, wood, and tile systems, plus adhesives. This narrow focus keeps testing straightforward and usually more affordable than broader certifications.
FloorScore only applies to hard surface flooring materials and related adhesives or underlayments. It doesn’t cover paint, furniture, insulation, or other finishes. If you want to address total building emissions, you’ll need other certifications too.
Its VOC limits are based on established standards, but it’s not always the strictest. GREENGUARD Gold, for example, uses lower emission thresholds for certain chemicals—especially in schools or places for sensitive groups. So, a FloorScore product might fit most commercial jobs but not work for projects that want the absolute lowest emissions.
FloorScore tests emissions, not raw material content. It doesn’t confirm recycled content, sourcing, or life‑cycle impact. If your team cares about broader sustainability, you’ll need to combine FloorScore with other environmental certifications.
GREENGUARD Gold is an advanced product testing certification that ensures building materials and furnishings meet the most rigorous chemical emission standards for sensitive individuals. UL Environment, part of Underwriters Laboratories (UL), manages both GREENGUARD and GREENGUARD Gold programs.
It’s all about low emissions of VOCs, including formaldehyde. Products have to pass chamber testing that measures what they give off into indoor air over time.
GREENGUARD Gold sets stricter VOC emission limits than standard GREENGUARD. UL tests products in chambers and compares results with health-based limits designed for schools and healthcare spaces.
Because the limits are lower, certified products release fewer chemicals indoors. Builders can confidently use these materials in classrooms, daycare centers, and hospitals—places where people spend hours inside.
GREENGUARD Gold isn’t just for flooring. It covers furniture, insulation, wall panels, paints, adhesives, and other building materials. That broad reach means project teams can pick multiple low-emission products under one label.
The certification works for green building programs like LEED and WELL, too. Designers can use GREENGUARD Gold products to meet air quality credits, often without extra emission testing.
Manufacturers face higher testing costs and longer approval times with GREENGUARD Gold. UL asks for detailed documentation and repeat chamber testing to prove compliance with those tough limits.
Testing takes time and uses third-party labs, so companies often pass some of the cost to buyers. GREENGUARD Gold products might cost more than similar non-certified options.
The certification only looks at indoor air emissions—not product safety or durability. It doesn’t rate structural strength, wear resistance, or recycled content. So, GREENGUARD Gold confirms low chemical emissions, but doesn’t replace other performance or environmental certifications you might need.
Both certifications use controlled chamber testing for chemical emissions, but they differ in what products they cover and how strict their limits are. That really affects where each label fits and how tough the VOC thresholds get.
Floor Score is just for flooring. It covers hardwood, laminate, vinyl, carpet, and adhesives used with flooring.
This narrow focus lets the program tailor emissions testing to floor coverings. Independent labs put samples in chambers and measure VOC release over time. For buyers, the label tells you about the flooring itself—not furniture or paint in the room.
GREENGUARD Gold is broader. It certifies flooring, furniture, wall coverings, insulation, even electronics.
Because it covers so much, GREENGUARD Gold sets rules that look at total indoor air exposure from different sources. That’s why you see it in schools and healthcare projects, where lots of materials need to meet one emissions benchmark.
Both limit total VOCs and specific chemicals like formaldehyde, but GREENGUARD Gold sets lower emission levels.
GREENGUARD Gold uses strict limits for formaldehyde and total VOCs, based on models for sensitive groups such as kids. Lower chamber concentration means products have to release fewer chemicals to pass. For owners, this means less long-term exposure in lived-in spaces.
Floor Score also uses third-party emissions testing and lines up with LEED and other green building programs. Its limits meet widely accepted indoor air quality criteria for homes and commercial spaces.
In short, both control VOC emissions with lab testing, but GREENGUARD Gold demands lower levels, especially for formaldehyde. That impacts which products qualify for high-sensitivity environments.
Your project goals, building type, and target certifications should drive your choice. Floor Score zeroes in on flooring-specific VOC emissions; GREENGUARD Gold sets stricter limits and covers more sensitive spaces.
Go with Floor Score when you’re focused on flooring compliance for standard residential, retail, or commercial spaces.
Floor Score tests finished flooring for VOC emissions in chambers over set periods. Because it’s just for flooring, it directly addresses emissions from LVP, laminate, hardwood, and carpet. That means you know your installed floor won’t release VOCs above recognized limits.
Major green building programs—like LEED and WELL—accept Floor Score for low-emitting flooring credits. For developers, this helps with documentation without needing extra product testing.
Floor Score fits projects balancing cost and sustainability. It confirms lower chemical emissions, which reduces indoor environmental impact, without the added scope of non-flooring items.
For big multifamily builds or retail rollouts using LVP in many units, Floor Score usually checks the compliance box without going overboard.
Pick GREENGUARD Gold for schools, childcare centers, healthcare facilities, or any project aiming for strict indoor air standards.
GREENGUARD Gold sets lower VOC limits than standard GREENGUARD. It was built for sensitive groups, especially kids and patients. The stricter chemical thresholds mean less formaldehyde and total VOCs. So, your finished space keeps measured emissions lower under test conditions.
Unlike Floor Score, GREENGUARD Gold covers more than just flooring—think furniture and other building materials. That wider scope helps teams create a consistent air quality strategy across the project.
High-end residential brands and healthcare developers often pick GREENGUARD Gold to boost their health and sustainability image. The certificate shows tighter emission compliance, which can help with green building documentation and branding tied to indoor environmental quality.
Suppliers love to say “low VOC” or “eco-friendly,” but without proof, those claims aren’t worth much. Buyers can protect themselves by asking for third-party test reports, checking certificate numbers, and confirming compliance with CARB II, TSCA Title VI, and CA Section 01350.
Ask for the actual certificate and lab report—not just a logo in a brochure. A real Floor Score or GREENGUARD Gold certificate lists the product name, manufacturer, cert body, and expiration date. These programs test finished products, so the listing must match the exact SKU. If the name doesn’t match, the certification probably doesn’t apply.
Check the certificate in the program’s public database. UL Solutions lists GREENGUARD Gold products online. Floor Score listings appear through its cert body. You can search by company name or certificate number to see if it’s active and not expired.
For composite wood, check CARB II and TSCA Title VI compliance docs. These rules limit formaldehyde from plywood, MDF, and particleboard. A compliant panel has a label or invoice statement from an approved certifier. This matters because LEED credits and some state projects require proof of CA Section 01350 or similar VOC tests.
If a supplier can’t give you traceable documents from a real program like Floor Score, GREENGUARD Gold, or Green Label Plus, treat their claims as just marketing fluff.
GREENGUARD Gold asks independent labs to put flooring in sealed chambers and measure how much formaldehyde and total VOCs it gives off over time. They track the actual emissions, not just what’s in the materials.
The program sets much stricter emission limits than regular GREENGUARD. So, for a floor to qualify, it has to release only tiny amounts of formaldehyde. That’s good news for anyone worried about indoor air—especially in homes, schools, or clinics where air quality really matters.
Instead of just checking what’s inside the flooring, GREENGUARD Gold looks at what actually gets into your air after installation. That’s what really impacts your indoor environment.
Floor Score uses environmental chambers to test vinyl flooring for total VOCs, formaldehyde, and other chemical emissions. The process sticks to standards that green building programs like LEED recognize.
Vinyl flooring often contains plasticizers and additives, so checking emissions is a big deal. Floor Score measures what the floor releases after it’s installed, making sure those chemicals stay well below the set safety limits.
Independent labs handle the testing, not just the manufacturers. That way, buyers get third-party proof instead of just trusting the company’s word.
If a product is Floor Score certified, it’s passed tests for low total VOC and formaldehyde emissions. These limits match up with indoor air quality standards from green building programs.
The focus here is on low-emitting flooring. That means less chemical buildup in places where air doesn’t circulate much—think bedrooms or offices with closed windows.
Since LEED and other rating systems accept Floor Score, builders often pick these products to meet project rules. For homeowners, it’s a sign the flooring has cleared standardized emission tests. That can be reassuring if you’re sensitive to air quality or just want to play it safe.
LVP has PVC, stabilizers, and plasticizers—ingredients that can let off VOCs after you put the floor in. That’s why independent emission testing really matters.
Both GREENGUARD Gold and Floor Score set VOC emission limits, but GREENGUARD Gold goes a bit stricter. This can make a difference in places like schools or hospitals, where people want the lowest possible chemical exposure.
For most homes, either certification means the LVP passed recognized air quality tests. What actually matters is that the product went through real chamber testing for VOCs and formaldehyde, not just some vague “low-VOC” claim on the label.
